Description

Translation method based on voice characteristics and electronic device for the same

Embodiments disclosed in this document relate to a translation method based on speech features and an electronic device therefor.

The electronic device may be configured to provide translation or interpretation. For example, the electronic device may acquire the user's voice (eg, speech) and provide translation or interpretation corresponding to the user's speech. An electronic device can acquire a voice signal from a user, perform voice recognition on the voice signal, and obtain text corresponding to the voice signal. The electronic device can provide translation corresponding to the user's speech by providing translated text for the text. The electronic device may provide interpretation through audio output based on the translated text.

For smoother translation or interpretation on electronic devices, translation based on machine learning can be used. For example, translation may be performed using a model learned using a transformer. For example, the electronic device may obtain a text translated from the first language into the second language by inputting the text of the first language into a learned model. The electronic device can perform translation in units of one sentence or multiple words.

Users can translate speech in real time using a translation application installed on the electronic device. For example, a user can translate the conversation partner's speech into his or her native language, or translate his or her own speech into the other person's native language. In order to translate the speech, the user can cause the electronic device to listen to the speech by performing input to the electronic device. The electronic device can activate the microphone based on user input and acquire speech through the activated microphone. Even if there is no user input to end listening, the electronic device can end listening. For example, when the end point of the speech is identified, the electronic device can deactivate the microphone and proceed with translation of the acquired speech.

Users can communicate with others who speak different languages. For example, a user can translate his or her speech using a translation application for conversation. The electronic device can identify the endpoint from the user's speech and end listening. However, the other party can give a speech after listening is completed. In this case, the user may need to activate the listening of the translation application again and request the other party to speak again.

An electronic device according to an embodiment disclosed in this document may include a microphone, a display, memory, and a processor. Memory can store instructions executable by the processor. The processor may activate the microphone based on a first user input to activate speech translation. The processor may receive an audio signal through an activated microphone and detect a first end point from the first voice signal included in the audio signal. The processor may display the first text based on a speech recognition result for the first speech signal preceding the first endpoint and the translated first text corresponding to the first text on the display. The processor may maintain the microphone activated for at least a first period of time following the first endpoint. When at least a portion of the second voice signal is detected from an audio signal acquired using a microphone within a first time interval, the processor detects a second endpoint of the second voice signal, and detects a second voice signal preceding the second endpoint. The second voice characteristic of the signal may be compared with the first voice characteristic of the first voice signal. If the first voice characteristic and the second voice characteristic do not match, the processor may display the second text based on the voice recognition result for the second voice signal. If the first voice characteristic and the second voice characteristic match, the processor may translate the second text and the second text into the target language and display the translated second text.

In a method for translation of an electronic device according to an embodiment disclosed in this document, the operation of activating the microphone of the electronic device based on a first user input to activate voice translation, and transmitting an audio signal through the activated microphone An operation of receiving, an operation of detecting a first end point from a first voice signal included in an audio signal, a first text and a first text based on a voice recognition result for the first voice signal preceding the first end point It may include displaying the translated first text corresponding to on the display of the electronic device. The method further comprises, when at least a portion of the second speech signal is detected using the microphone within a first time interval subsequent to the first endpoint, combining the second speech characteristic of the second speech signal and the first speech characteristic of the first speech signal. May include comparison operations. The method may include displaying a second text based on a speech recognition result for the second speech signal if the first speech characteristic and the second speech characteristic do not match based on the comparison. The method may include, when the first voice characteristic and the second voice characteristic match, translating the second text and the second text into the target language and displaying the translated second text.

An electronic device according to an embodiment of the present disclosure can provide smoother translation through extended listening time.

An electronic device according to an embodiment of the present disclosure can provide translation that meets the user's intent by determining whether to translate based on voice characteristics.

The electronic device 501-1 of FIG. 7A may be an electronic device that includes the configuration of the electronic device 501 described above with reference to FIG. 6 . The description of the electronic device 501-1 described later in relation to FIG. 7A may be equally applied to the electronic device 501 of FIG. 6.

According to one embodiment, the electronic device 501-1 may include a plurality of modules. For example, at least some of the components of the electronic device 501-1 described with reference to FIG. 7A may be software modules implemented by executing instructions stored in the memory 630 by the processor 620. At least some of the modules of the electronic device 501-1 may be hardware modules. For example, the memory 630 may store the speaker identification model DB 745. For example, end point detection (EPD) module 730, speaker identification module 740, ASR module 750, translation module 760, execution module 770, and/or microphone control module 780. It may be a software module.

According to one embodiment, the electronic device 501-1 may activate the microphone 650 based on user input. For example, the electronic device 501 may display the UI (eg, UI of FIG. 11 ) of the translation application on the display 660 according to the execution of the translation application. The electronic device 501-1 may activate the microphone 650 when an input to the UI (eg, an input to the button 1110 of FIG. 11) is received. For example, the electronic device 501-1 may activate the microphone 650 using the microphone control module 780. Using the activated microphone 650, the electronic device 501-1 can acquire an audio signal. In this disclosure, an audio signal may be referred to as digitized audio information or an analog audio signal, unless otherwise specified. Using the activated microphone 650, the electronic device 501-1 can acquire a voice signal. In the present disclosure, a voice signal may refer to a signal corresponding to a voice band among audio signals or the audio signal itself. In one example, the electronic device 501-1 performs preprocessing on the audio signal (e.g., frequency band filtering, noise suppression, automatic gain control (AGC), acoustic echo cancelling (AEC), noise cancellation, and/or A voice signal can be obtained from an audio signal through windowing.

In one example, the electronic device 501-1 can identify voice characteristics from a voice signal. For example, the electronic device 501-1 may identify voice features (eg, at least one of speaker, age, gender, or language) using the speaker identification module 740. The speaker identification module 740 can identify voice features corresponding to the voice signal by extracting a voice vector from the voice signal. The speaker identification module 740 may identify at least one of the speaker, age, gender, or language of the voice included in the voice signal based on the voice vector.

The speaker identification module 740 can identify the speaker of a voice from a voice signal. For example, the speaker identification model DB 745 may include at least one speaker identification model (eg, speaker identification vector). One speaker identification model may correspond to a previously generated speech vector based on the speech of one speaker. The speaker identification module 740 converts the received voice signal into a voice vector and compares the voice vector with the speaker identification model stored in the speaker identification model DB 745 to identify the speaker. For example, if the similarity (e.g., likelihood ratio test (LRT), Euclidian distance, or Cosine similarity) between the speech vector and the speaker identification model is greater than or equal to the specified similarity, the speaker identification module 740 determines that the speaker in the speech signal is stored. It can be determined by corresponding to the speaker in the identification model.

The speaker identification module 740 may identify the speaker's age and/or gender from the voice signal. For example, the speaker identification module 740 may extract features of a voice signal and identify the speaker's age, gender, and/or language based on the pattern of features.

The speaker identification module 740 can extract linguistic features of the voice signal and identify the language of the voice included in the voice signal based on the feature pattern. In one example, language identification of the speech signal may be performed by translation module 760.

For example, the ASR module 750 may convert a voice signal obtained by the microphone 650 into text. The electronic device 505-1 may display text converted by the ASR module 750 on the display 660. For example, the electronic device 505-1 can convert voice signals in real time and display text.

EPD module 730 can detect the endpoint from the voice signal. For example, the EPD module 730 may detect the end point of the voice signal when a silence section exceeding the first threshold time is detected from the voice signal. In the present disclosure, a silent section may be referred to as a section in which no voice is detected from a voice signal. The EPD module 730 may detect a section in which the volume of the voice signal is less than or equal to a specified value as a silent section. The EPD module 730 may detect a section in which a signal component corresponding to a designated band (e.g., human voice band) is not detected from the voice signal as a silent section. When an endpoint is identified from a voice signal, the EPD module 730 may transmit information indicating that the endpoint has been identified to the ASR module 750.

According to one embodiment, the electronic device 501-1 may maintain the microphone 650 in an activated state even if an endpoint is detected. For example, the electronic device 501-1 may maintain the microphone 650 in an activated state for at least a specified time (eg, a second threshold time) after detecting the endpoint.

In one example, if a voice signal is not detected within a specified time (eg, a second threshold time), the electronic device 501-1 may deactivate the microphone 650. For example, the electronic device 501-1 may deactivate the microphone 650 using the microphone control module 780. When information indicating that an endpoint is identified is received, the ASR module 750 may transmit the text converted from the voice signal to the translation module 760. The converted text may be text corresponding to the voice acquired before endpoint detection. The converted text may be text corresponding to a voice signal (eg, a first voice signal) from when the microphone 650 is activated until the end point is detected.

In one example, while the microphone 650 is activated after detecting the endpoint, the electronic device 501-1 may acquire a subsequent voice signal (eg, a second voice signal) through the microphone 650. For example, a voice signal acquired subsequent to an endpoint may be referred to as a second voice signal, and a voice signal acquired prior to an endpoint may be referred to as a first voice signal. The ASR module 750 may display text corresponding to the second voice signal on the display 660.

According to one embodiment, the speaker identification module 740 may compare the first voice feature of the first voice signal and the second voice feature of the second voice signal. For example, speaker identification module 740 may compare the speaker, age, gender, and/or language of the first and second voice signals.

For example, the speaker identification module 740 may determine that the second voice characteristic corresponds to the first voice characteristic if the similarity between the first voice characteristic and the second voice characteristic is greater than or equal to a preset value. If the similarity between the first voice feature and the second voice feature is less than a preset value, or if the difference exceeds a specified range, the speaker identification module 740 may determine that the first speaker and the second speaker are different speakers. .

For example, the speaker identification module 740 may determine whether the first speaker of the first voice signal and the second speaker of the second voice signal are the same speaker. If the first speaker and the second speaker are determined to be the same speaker, the speaker identification module 740 may determine that the first voice feature and the second voice feature correspond. The speaker identification module 740 may identify the speaker corresponding to the first voice signal using the first voice signal and the speaker identification model stored in the speaker identification module DB 745. The speaker identification module 740 may attempt to identify the speaker corresponding to the second voice signal using the second voice signal and the speaker identification model stored in the speaker identification module DB 745. For example, if the first voice signal and the second voice signal correspond to the same speaker, the speaker identification module 740 may determine that the first voice feature and the second voice feature correspond. For example, when the first voice signal and the second voice signal correspond to different speakers or when speaker identification for the second voice signal fails, the speaker identification module 740 uses the first voice feature and the second voice feature. You can decide not to respond.

For example, the speaker identification module 740 may determine that the first voice feature corresponds to the second voice feature if at least one of age, gender, or language of the first voice signal and the second voice signal is the same. .

According to one embodiment, if the first voice feature and the second voice feature do not correspond, the ASR module 750 may transmit the first text corresponding to the first voice signal to the translation module 760. The translation module 760 may obtain the translated first text by translating the first text obtained from the ASR module 750 into the target language. The translation module 760 may translate the text corresponding to the voice signal into the target language, for example, based on machine learning. The translation methods in this disclosure are exemplary, and those skilled in the art will understand that any of a variety of translation methods may be used. The execution module 770 may provide the translated first text through the display 660. The execution module 770 may provide the translated first text through a speaker (not shown). In one example, execution module 770 may cause microphone control module 780 to disable microphone 650 when providing translated first text. In this case, translation for the second text may not be provided. In one example, execution module 770 can display a button for translation of the second text on display 660.

According to one embodiment, if the first speech feature corresponds to the second speech feature, the ASR module 750 sends a first text corresponding to the first speech signal and a second text corresponding to the second speech signal to the translation module 760. 2 Text can be transmitted. For example, ASR module 750 may forward the first text and second text to translation module 760 once the endpoint for the second speech signal is identified. In one example, the translation module 760 may obtain the translated first and second texts by translating the first and second texts obtained from the ASR module 750 into the target language. In one example, when the first text and the second text constitute one sentence, the translation module 760 may obtain one translated sentence by combining the first text and the second text and translating it into the target language. there is. The execution module 770 may provide the translated first and second texts through the display 660. The execution module 770 may provide the translated first and second texts through a speaker (not shown). In one example, execution module 770 may cause microphone control module 780 to disable microphone 650 when providing translated first and second texts.

In one example, the first voice feature and the second voice feature do not correspond, but the electronic device 505-1 may provide translated second text that corresponds to the second voice signal. For example, the first voice feature may correspond to the first speaker in the speaker identification model DB 745, and the second voice feature may correspond to the second speaker in the speaker identification model DB 745. Although the second voice signal is from a different speaker than the first voice signal, the speaker of the second voice signal may also correspond to a speaker previously stored in the electronic device 505-1. In this case, similar to the case where the first voice feature and the second voice feature correspond to each other, the electronic device 505-1 may provide the translated second text.

As described above with respect to FIG. 5 , translation of text may be performed by the server device 511 of FIG. 5 . In this case, the electronic device 501-1 may transmit text corresponding to the voice signal to the server device using the communication circuit 690 and obtain translated text from the server device. In one example, translation module 760 may be omitted.

Referring to FIGS. 6 and 7B , the electronic device 501-2 of FIG. 7B is an example of the electronic device 501 of FIG. 6 . The electronic device 501-2 of FIG. 7B may be an electronic device that includes the configuration of the electronic device 501 described above with reference to FIG. 6 . The description of the electronic device 501-2 described later in relation to FIG. 7B may be equally applied to the electronic device 501 of FIG. 6. Unless otherwise stated, the description described with respect to the electronic device 501-1 in FIG. 7A may be applied to the electronic device 501-2 in FIG. 7B.

In the example of FIG. 7B, the electronic device 501-2 may obtain an audio signal or voice signal from the surrounding electronic device 521. The electronic device 501-2 may be connected to the peripheral electronic device 521 using the communication circuit 690.

According to one embodiment, the peripheral electronic device 521 may include a microphone 651, a voice activity detection (VAD) module 710, a microphone control module 720, and a communication circuit 691. The peripheral electronic device 521 may communicate with the electronic device 501-2 using the communication circuit 691.

In one example, the peripheral electronic device 521 may be a wearable electronic device that can be worn on the user's body, such as earbuds or AR glasses. The peripheral electronic device 521 can detect whether the wearer utters a utterance using the VAD module 710. For example, the peripheral electronic device 521 can detect speech by the wearer by using an acceleration sensor to detect a change in acceleration according to the wearer's speech.

When transmitting a voice signal to the electronic device 501-2, the peripheral electronic device 521 can inform whether the voice signal was uttered by the wearer. In this case, the speaker identification module 740 may determine whether the first voice feature corresponds to the second voice feature based on information received from the peripheral electronic device 521. For example, the first voice signal may be from the wearer of the peripheral electronic device 521, but the second voice signal may not be from the wearer of the peripheral electronic device 521. In this case, the electronic device 501-2 may determine that the speaker of the first voice signal and the speaker of the second voice signal are different based on information received from the peripheral electronic device 521.

As described above with reference to FIG. 7A, the electronic device 501-2 determines whether the first voice feature of the first voice signal corresponds to the second voice feature of the second voice signal, and provides a translation based on the determination. The provision is as described above. However, in the embodiment of FIG. 7B, the execution module 770 may provide feedback (eg, auditory feedback) through the peripheral electronic device 521. The electronic device 501-2 may determine control of the microphone 651 of the peripheral electronic device 521 using the microphone control module 780. The microphone control module 720 of the peripheral electronic device 521 may control the microphone 651 based on the microphone control signal received from the electronic device 501-2.

Below, various operations of the electronic device 501 may be described with reference to FIGS. 8 to 16 . The following disclosure may be applied to the electronic device 501-1 in FIG. 7A and/or the electronic device 501-2 in FIG. 7B. Those skilled in the art will understand that descriptions of various operations described below may change depending on the configuration of the electronic device 501-1 in FIG. 7A or the electronic device 501-2 in FIG. 7B.

Figure 8 shows an example of a conversation for which translation is provided.

Referring to FIGS. 6 and 8 , for example, a speaker 599 and the other speaker 598 may be having a conversation. For example, speaker 599 may be a user of electronic device 501. For example, the other speaker 598 may be a conversation partner whose speaker identification model is not stored in the electronic device 501.

In the first time interval T1, the speaker 599 may utter the first speech 801. The second time section T2 may be a silent section between the first speech 801 and the second speech 802. The second time interval T2 is longer than the first threshold time TH1, but is shorter than the first threshold time TH1 and the second threshold time TH2. For example, the first threshold time (TH1) may be a threshold time for endpoint detection. The electronic device 501 may detect the end point of the first speech 801 by detecting a silence period longer than the first threshold time TH1.

As described above, the electronic device 501 may maintain the activated state of the microphone 650 for the second threshold time TH2 even after detection of the endpoint. The electronic device 501 may display the first text (e.g., automatic voice recognition result for the first speech) corresponding to the first speech 801 on the display 660. The electronic device 501 may display the translated first text by translating the first text into the target language.

In the third time interval T3, the electronic device 501 may acquire the second speech 802. The electronic device 501 may display the second text (e.g., automatic voice recognition result for the second speech) corresponding to the second speech 802 on the display 660.

When acquiring the second speech 802, it may be determined whether the first voice feature of the first speech 801 of the electronic device 501 corresponds to the second voice feature of the second speech 802. For example, the electronic device 501 may determine whether the first voice feature and the second voice feature correspond according to the method described above with reference to FIG. 7A. In the example of FIG. 8, because both the first speech 801 and the second speech 802 were uttered by the speaker 599, the electronic device 501 determines that the first speech feature corresponds to the second speech feature. You can decide. In this case, the electronic device 501 may provide translations corresponding to the first text of the first speech 801 and the second text of the second speech 802. Electronic device 501 may provide translations visually and/or audibly. The electronic device 501 may additionally display a translated second text corresponding to the second text.

The fourth time section T4 may be a silent section between the second speech 802 and the third speech 803. The fourth time interval T4 is longer than the first threshold time TH1, but is shorter than the first threshold time TH1 and the second threshold time TH2. The electronic device 501 may detect the end point of the second speech 802 by detecting a silence period longer than the first threshold time TH1. The electronic device 501 may provide a translation when the endpoint of the second speech 802 is detected.

In the fifth time interval T5, the electronic device 501 may acquire the third speech 803 through the activated microphone 650. The third speech 803 may be uttered by the other speaker 598. The electronic device 501 may determine whether the second voice feature of the second speech 802 and the second voice feature of the third speech 803 correspond. For example, the electronic device 501 may determine whether the second voice feature and the third voice feature correspond according to the method described above with reference to FIG. 7A. In the example of FIG. 8, because the second speech 802 and the third speech 803 were uttered by different speakers, the electronic device 501 determines that the second speech feature does not correspond to the third speech feature. You can. In this case, the electronic device 501 may provide a third text corresponding to the third speech 803. In one example, the electronic device 501 may display a button for translating the third text together with the third text.

Figure 9 shows an example of a conversation for which translation is provided.

In the example of FIG. 9 , the other speaker 598 may perform the fourth speech 904 instead of the third speech 803 of FIG. 8 . Descriptions of the first speech 801 and the second speech 802 may be referenced by the description related to FIG. 8.

Referring to FIGS. 6 and 9 , in the fourth time period T4, the electronic device 501 may detect a silence period exceeding the first threshold time TH1 and the second threshold time TH2. As the second threshold time (TH2) is exceeded, the electronic device 501 may deactivate the microphone 650. Accordingly, the fourth speech 903 of the other speaker 598 in the fifth time interval T5 may not be received by the electronic device 501.

Figure 10 shows an example of a conversation for which translation is provided.

In the example of FIG. 10, a fellow speaker 597 may speak instead of the other speaker 598 of FIG. 9. The electronic device 501 may be assumed to have stored the speaker identification model of the fellow speaker 597. Descriptions of the first speech 801 and the second speech 802 may be referenced by the description related to FIG. 8 .

The fourth time interval T4 is longer than the first threshold time TH1, but is shorter than the first threshold time TH1 and the second threshold time TH2. In the fifth time interval T5, the electronic device 501 may acquire the fifth speech 1003 through the activated microphone 650. The fifth speech 1003 may be an utterance by a fellow speaker 597.

The electronic device 501 may determine whether the second voice feature of the second speech 802 corresponds to the fifth voice feature of the fifth speech 1003. For example, the electronic device 501 may determine whether the second voice feature and the fifth voice feature correspond according to the method described above with reference to FIG. 7A.

In the example of FIG. 10, because the second speech 802 and the fifth speech 1003 were uttered by different speakers, the electronic device 501 determines that the second speech feature does not correspond to the fifth speech feature. You can. In one example, the electronic device 501 may determine whether the fifth speech 1003 is uttered by the speaker for whom information is stored. If the fifth voice feature of the fifth speech 1003 corresponds to the speaker recognition model stored in the memory 630, the electronic device 501 may determine that the fifth speech 1003 is an utterance by the stored speaker. In this case, the electronic device 501 may visually and/or audibly provide a translation corresponding to the fifth speech 1003.

Referring to FIGS. 6 and 11 , according to one embodiment, the electronic device 501 may provide a translation UI according to execution of a translation application. For example, the first screen 1100-1 may correspond to an initial screen provided upon execution of a translation application. The first screen 1100-1 may include a listening button 1110. When an input to the listening button 1110 is received, the electronic device 501 may enter the listening mode for at least a specified period of time. In listening mode, the electronic device 501 may activate the microphone 650. The electronic device 501 may display a second screen 1100-2 on the display 660 indicating that it is in listening mode. When the listening mode ends, the electronic device 501 may return to its initial state. For example, the electronic device 501 may output the first screen 1100-1 in the initial state.

Referring to FIGS. 6 and 12 , the electronic device 501 may display the third screen 1200-1 as part of the translation UI. For example, the third screen 1200-1 may be a screen output according to reception of the first speech 801 and the second speech 802 of FIGS. 8, 9, and 10. For example, upon receiving the first speech 801, the electronic device 501 may generate a first text 1210 corresponding to the first speech 801 and a translated first text 1210 corresponding to the first text 1210. Text 1220 can be displayed. Upon receiving the second speech 802, the electronic device 501 may display the second text 1230 corresponding to the second speech 802.

In the example of FIG. 12 , because the first speech feature of the first speech 801 corresponds to the second speech feature of the second speech 802, the electronic device 501 displays the second text 1230 and the translated first speech 802. 2 Text (1240) can be provided. For example, as shown in the fourth screen 1200-2, the electronic device 501 may display the translated text adjacent to the corresponding text. In one example, the first text 1210 and the second text 1230 may constitute one sentence. In this case, the electronic device 501 may provide a translation corresponding to the sentence composed of the first text 1210 and the second text 1230. The translation may be displayed below the second text 1230.

Referring to FIGS. 6 and 13 , the electronic device 501 may display the fifth screen 1300 as part of the translation UI. For example, the fifth screen 1300 may be a screen displayed by the electronic device 501 upon reception of the third speech 803 of FIG. 8. As described above with respect to FIG. 8 , the phonetic characteristics of the second speech 802 may not correspond to the phonetic characteristics of the third speech 803 . The electronic device 501 may display the third text 1310 corresponding to the third speech 803. The electronic device 501 may display a translation button 1320 along with the third text 1310. In one example, the electronic device 501 may display the third text 1310, which has different voice characteristics, differently from the first text 1210 and the second text 1230. For example, the electronic device 501 may align the third text 1310 differently from the first text 1210 and the second text 1230. For example, the electronic device 501 may additionally display arbitrary graphics (eg, icons) to distinguish the speaker of the third text 1230.

In the example of FIG. 13 , as the listening mode ends, the electronic device 501 may display the listening button 1110 again.

Referring to FIGS. 6 and 14 , the electronic device 501 may display the sixth screen 1400 as part of the translation UI.

For example, when an input to the translation button 1320 of FIG. 13 is received, the electronic device 501 may display the translated third text 1410 for the third text 1310. For example, as in the example of FIG. 8, if the voice characteristics are different from the previous voice signal and the speaker of the voice signal is not the stored speaker, the electronic device 501 may display the fifth screen 1300 of FIG. 13. You can. When an input to the translation button 1320 of the fifth screen 1300 is received, the electronic device 501 may display the sixth screen 1400.

For example, as described above with reference to FIG. 10 , the third text 1310 may correspond to an utterance by a speaker stored in the electronic device 501 (e.g., fellow speaker 597 in FIG. 10 ). In this case, the electronic device 501 can display the translated third text 1410 even if no input for a separate translation button is received.

In the examples described above with reference to FIGS. 12, 13, and 14, the electronic device 501 may display speech-corresponding text so that speech by different speakers can be visually distinguished for speaker distinction. 12, 13, and 14, the alignment of the text is different depending on the speaker, but this is an example and the embodiments of the present disclosure are not limited thereto.

6 and 15, according to one embodiment, the electronic device 501 may be configured to provide translation based on speaker characteristics (e.g., at least one of voice vector, age, gender, or language). .

In operation 1505, the electronic device 501 activates the microphone 650 and receives first audio. For example, the electronic device 501 may activate the microphone 650 when an input to the listening button 1110 of FIG. 11 is received. The electronic device 501 may receive first audio using the activated microphone 650.

In operation 1510, the electronic device 501 may determine whether the silent time period exceeds a first threshold time (eg, the first threshold time TH1 in FIG. 8). When a silent time period exceeding the first threshold time is detected, the electronic device 501 may identify the end point. For example, operation 1510 may correspond to the operation of EPD module 730 described above with respect to FIG. 7A. If a silent time period exceeding the first threshold time is not detected (e.g., operation 1510-NO), the electronic device 501 may continue to receive the first audio.

When a silent time period exceeding the first threshold time is detected (e.g., operation 1510-YES), in operation 1515, the electronic device 501 may display the first audio corresponding text and the translated first text. The electronic device 501 may detect the end point of the first audio and display text corresponding to the first audio using the ASR module 750 described above with reference to FIG. 7A. The electronic device 501 may obtain the translated first text using the translation module 760 described above with reference to FIG. 7A. For example, the electronic device 501 may transmit the first audio-corresponding text to the server device and receive the first audio-corresponding translated text from the server device using the communication circuit 690.

In operation 1520, the electronic device 501 may determine whether the second audio is received within a second threshold time (eg, the second threshold time TH2 in FIG. 8). For example, when the first threshold time expires, the electronic device 501 may maintain the activated state of the microphone 650 for at least a second threshold time.

If the second audio is not received within the second threshold time (e.g., operation 1520-NO), in operation 1545, the electronic device 501 may end the listening mode.

If the second audio is received within the second threshold time (e.g., operation 1520-YES), in operation 1525, the electronic device 501 may determine whether the first speaker feature corresponds to the second speaker feature. The first speaker feature may correspond to the speaker feature of the first audio, and the second speaker feature may correspond to the speaker feature of the second audio. For example, the electronic device 501 may determine whether the first speaker feature corresponds to (eg, matches) the second speaker feature using the speaker identification module 740 of FIG. 7A. Speaker characteristics may include at least one of voice vector, gender, age, or language.

If the first speaker feature corresponds to the second speaker feature (e.g., operation 1525-YES), in operation 1530, the electronic device 501 may display the second audio corresponding text and the translated second text. The translated second text may be a text obtained by translating the second audio corresponding text into the target language.

If the first speaker feature does not correspond to the second speaker feature (e.g., operation 1525-NO), in operation 1535, the electronic device 501 may determine whether the second speaker is the stored speaker. For example, when a speaker authentication model corresponding to a second speaker is stored, the electronic device 501 may determine that the second speaker is the stored speaker. If the second speaker is a stored speaker (e.g., operation 1535-YES), the electronic device 501 may display the translated text according to operation 1530.

If the second speaker is not the stored speaker (e.g., operation 1535-NO), the electronic device 501 may display the second text corresponding to the second audio according to operation 1540. In this case, the electronic device 501 may not display the translated text of the second audio corresponding text. The electronic device 501 may display a button for translating the second text corresponding to the second audio (eg, the translation button 1320 of FIG. 13) along with the second text corresponding to the second audio.

Referring to FIGS. 6 and 16 , according to one embodiment, the electronic device 501 may be set to provide translation based on voice characteristics (eg, at least one of speaker, age, gender, or language).

In operation 1605, the electronic device 501 may activate the microphone 650 based on a first user input to activate voice translation. For example, the electronic device 501 may activate the microphone 650 when an input to the listening button 1110 of FIG. 11 is received.

In operation 1610, the electronic device 501 may receive an audio signal through an activated microphone. In operation 1615, the electronic device 501 may detect the first endpoint from the first voice signal included in the audio signal. For example, the electronic device 501 may detect the first endpoint when a silent section exceeding a first threshold time (eg, the first threshold time TH1 in FIG. 8) is identified from the audio signal. For example, operation 1615 may correspond to the operation of EPD module 730 described above with respect to FIG. 7A.

In operation 1620, the electronic device 501 may display the first text and the translated first text based on the voice recognition result for the first voice signal. For example, the first speech signal may be referenced to a previously acquired speech signal of the first endpoint. The electronic device 501 may display the first text corresponding to the first voice signal using the ASR module 750 described above with reference to FIG. 7A. The electronic device 501 may obtain the translated first text using the translation module 760 described above with reference to FIG. 7A. For example, the electronic device 501 may transmit the first audio corresponding text to the server device and receive the translated first text from the server device using the communication circuit 690.

In operation 1625, the electronic device 501 may display the activation state of the microphone 650 for at least a first time period (eg, the second threshold time TH2 in FIG. 8). In one example, the electronic device 501 may deactivate the microphone 650 if a voice signal is not detected within the first time period.

In operation 1630, when at least a portion of the second voice signal is detected from the audio signal acquired within the first time interval, the electronic device 501 may display the second text. The first voice characteristic and the second voice characteristic can be compared. For example, the first voice characteristic may correspond to the voice characteristic of the first voice signal, and the second voice characteristic may correspond to the voice characteristic of the second voice signal.

In operation 1635, the electronic device 501 may determine whether the first voice characteristic and the second voice characteristic match. The first voice characteristic may correspond to the voice characteristic of the first voice signal, and the second voice characteristic may correspond to the voice characteristic of the second voice signal. For example, the electronic device 501 may determine whether the first voice characteristic matches (eg, corresponds to) the second voice characteristic using the speaker identification module 740 of FIG. 7A. Voice characteristics may include at least one of a feature distribution pattern, gender, age, or language. In one example, the electronic device 501 may identify a first similarity between a speaker identification model stored in memory 630 and a first speech characteristic, and identify a second similarity between a speaker identification model and the second speech characteristic. You can. If the difference between the first similarity and the second similarity is within a specified range, the electronic device 501 may determine that the first voice characteristic and the second voice characteristic are matched.

If the first voice characteristic and the second voice characteristic match (e.g., operation 1635-YES), the electronic device 501 may display the second text and the translated second text in operation 1640. In one example, the translated second text may be a text obtained by translating the first text and the second text into the target language. For example, the electronic device 501 may identify the second endpoint of the second voice signal when a silent section exceeding a first threshold time (e.g., the first threshold time (TH1) of FIG. 8) is identified from the audio signal. You can. Once the second endpoint is identified, the electronic device 501 can translate the first text and the second text into the target language.

If the first voice characteristic and the second voice characteristic do not match (e.g., operation 1635-NO), in operation 1645, the electronic device 501 may display a second text corresponding to the second voice signal. In this case, the electronic device 501 may display the second text without the translated second text. For example, the electronic device 501 may display an icon (eg, translation button 1320 in FIG. 13) for requesting translation of the second text along with the second text. When a second user input for an icon is received, the electronic device 501 may display the translated second text by translating the second text into the target language along with the second text.

Additionally, as described above in connection with operation 1535 of FIG. 15 , if the first voice characteristic and the second voice characteristic do not match, the electronic device 501 matches the second voice characteristic with the speaker recognition model stored in the memory 630. You can compare. If the second voice characteristic corresponds to the stored speaker recognition model, the electronic device 501 may display the second text and the translated second text by translating the second text into the target language.
