With continued reference to FIG. 2, a flow 200 of one embodiment of a method for waking up an electronic device in accordance with the present application is shown. The method for waking up the electronic device comprises the following steps:
In this embodiment, an execution subject of the method for waking up the electronic device (such as the terminal device 101 shown in fig. 1) may acquire the voice to be recognized in a wired connection manner or a wireless connection manner. The speech to be recognized may include a speech of a target user. The target user may be any user, or may be a user determined according to a rule, for example, a user having a wake-up authority for an electronic device determined according to a Voiceprint Recognition (VPR) technology. Optionally, the speech to be recognized may further include speech of which the length of the speech segment is smaller than a preset threshold.
Specifically, the executing body may acquire the voice to be recognized, which is pre-stored locally, or may acquire the voice to be recognized, which is transmitted by a voice input device (e.g., a microphone) communicatively connected to the executing body.
It should be noted that the speech may include, but is not limited to, a complete speech segment with a definite beginning and ending. The speech may also be a speech segment in a continuous stream of speech.
In this embodiment, the executing entity may perform recognition on the speech to be recognized acquired in step 201 by using various speech recognition techniques to generate a first speech recognition result. The voice recognition technology can comprise a traditional voice recognition method and an end-to-end acoustic model training method combined with an artificial neural network. The above conventional speech recognition methods generally include feature extraction, acoustic model matching, language models, and the like. The end-to-end acoustic model training method may include generating a speech recognition result using a model constructed based on a DTW (Dynamic Time Warping) algorithm, a CTC (connection Temporal Classification) algorithm, and the like.
In some optional implementation manners of this embodiment, the executing body may further perform word segmentation on a result of recognizing the speech to be recognized according to a preset number of characters, and generate at least one word with a number of characters not exceeding the preset number of characters as the first speech recognition result.
In this embodiment, the execution main body may determine whether a wakeup word including the first speech recognition result exists in a preset wakeup word set in various ways. Wherein the number of characters included in the wake-up word is generally greater than the number of characters included in the first speech recognition result. As an example, the execution main body may use the first speech recognition result as a search term, and determine whether a search result including the search term exists in the preset wake-up term set.
In some optional implementation manners of this embodiment, in response to determining that a matching wakeup word exists in the preset wakeup word set, the execution main body may determine that a wakeup word including a character string in the first speech recognition result exists in the preset wakeup word set. And the matched awakening words comprise character strings consistent with the first voice recognition result. For example, the first N characters of the matching wake-up word are consistent with the first speech recognition result. As an example, the first speech recognition result may be "small K" or "small K small". As yet another example, the first speech recognition result may also be "XX" or "XX-the same". Then, the matching wake words corresponding to the above-described first speech recognition result may be "small K" and "XX classmates", respectively.
In this embodiment, in response to determining that there is a search result including the search term, the execution subject may generate pre-wake information indicating that pre-wake is allowed. In response to determining that there is no search result including the search term, the execution subject may generate pre-wake-up information characterizing that pre-wake-up is not allowed.
And step 205, waking up the electronic device based on the pre-wake-up information.
In this embodiment, based on the pre-wake-up information generated in the step 203, the executing entity may wake up the electronic device in various ways. As an example, the execution subject may wake up the electronic device directly in response to determining that the pre-wake-up information is used to characterize that pre-wake-up is allowed. It should be noted that the awakened electronic device may be the execution main body itself.
With continued reference to fig. 3, fig. 3 is a schematic diagram of an application scenario of a method for waking up an electronic device according to an embodiment of the present application. In the application scenario of fig. 3, a user 301 is ready to wake up a smart terminal device (e.g. a smart sound box) 302. Thus, the user 301 speaks the wake word by word towards the smart terminal device 302. The intelligent terminal device 302 acquires the voice 303 of the user 301 speaking the awakening word by word. Then, the intelligent terminal device 302 performs speech recognition on the speech 303 to generate a first speech recognition result "small K small" 304. According to the fact that the wake-up word "small K" including the first speech recognition result 304 exists in the preset wake-up word set, the smart terminal device 302 may generate the pre-wake-up information 305 indicating that pre-wake-up is allowed. Then, according to the above pre-wake-up information 305 for representing that pre-wake-up is allowed, the smart terminal device 302 can be directly woken up, i.e. switched to the operating mode.
At present, in one of the prior arts, after a user completely speaks a wake word, the electronic device matches the wake word again, which results in a low wake speed of the electronic device. In the method provided by the embodiment of the application, the first voice recognition result containing the characters with the number smaller than that of the characters contained in the awakening word is generated through the voice to be recognized, the pre-awakening information is further generated, and then the electronic equipment is awakened according to the pre-awakening information. Therefore, the user can start to match the awakening words before the user speaks the complete awakening words, and the awakening speed of the electronic equipment is improved. From the perspective of the user, the time for waiting for the electronic equipment to wake up is reduced, and the user experience is improved.
With further reference to fig. 4, a flow 400 of yet another embodiment of a method for waking an electronic device is shown. The flow 400 of the method for waking up an electronic device includes the following steps:
The above steps 401, 402, and 404 are respectively consistent with the steps 201, 202, 204, and their optional implementations in the foregoing embodiment, the above step 403 is consistent with the corresponding optional implementation in the foregoing embodiment, and the above descriptions for the steps 201, 202, 204, their optional implementations, and the optional implementation of the step 203 also apply to the steps 401, 402, 403, and 404, which are not described again here.
In some optional implementations, in response to determining that the pre-wake-up information is used to characterize that pre-wake-up is allowed, the execution body may further send response information characterizing that the electronic device is woken up. Based on the optional implementation manner, the electronic device may send response information of the wake-up device to the user when acquiring the corresponding pre-wake-up information. Compared with the method that the user waits for the user to speak the complete awakening word and then matches the awakening word, the response information is sent to the user, the time for the user to wait for the awakening response is shortened, the awakening rate of the electronic equipment is improved, and therefore the user experience is improved.
In response to determining that the pre-wake information is used to characterize the pre-wake allowed, a subsequent voice associated with the voice to be recognized is obtained, step 405.
In this embodiment, an executing entity (e.g., the server 105 shown in fig. 1) of the method for waking up the electronic device may retrieve subsequent speech associated with the speech to be recognized in response to determining that the pre-wake information is used to characterize the pre-wake allowed. Wherein, the acquisition time of the subsequent voice is generally later than the voice to be recognized.
It should be noted that, in the context of a continuous speech stream, the first frame of the subsequent speech may be generally consecutive in time with the last frame of the speech to be recognized.
In response to determining that the pre-wake-up information is used to characterize that pre-wake-up is allowed, the execution subject may obtain a pre-stored subsequent voice from a local location, as an example; as still another example, the execution subject may acquire the subsequent voice from the same device (e.g., a microphone) as the voice to be recognized.
In this embodiment, based on matching between the to-be-recognized speech and the subsequent speech and the preset wake-up word set, the execution main body may wake up the electronic device in various ways. As an example, the execution subject may splice the speech to be recognized and the subsequent speech into a target speech according to the collection time. Then, the execution subject may perform speech recognition on the target speech to generate a target speech recognition result. Next, the executing body may determine whether the target speech recognition result includes a wakeup word in the preset wakeup word set. In response to determining to include, the execution body may be awakened.
In some optional implementation manners of this embodiment, the executing main body may further wake up the electronic device according to the following steps:
the first step is to perform voice recognition on the subsequent voice to generate a second voice recognition result.
In these implementations, the execution subject may generate the second speech recognition result in a manner similar to the generation of the first speech recognition result.
And secondly, splicing the first voice recognition result and the second voice recognition result according to the acquisition time to generate a target voice recognition result.
In these implementations, the executing body may splice the first speech recognition result obtained in the step 402 and the second speech recognition result obtained in the first step according to the speech acquisition time, so as to generate a target speech recognition result. As an example, the first speech recognition result may be "XX" and the second speech recognition result may be "classmate". Then, the execution agent may generate a target speech recognition result "XX classmate".
And thirdly, responding to the fact that the target voice recognition result is consistent with the matched awakening words, and awakening the electronic equipment.
In these implementations, the executing entity may wake the electronic device in response to determining that the target speech recognition result is consistent with the matching wake word.
As can be seen from fig. 4, the flow 400 of the method for waking up the electronic device in the present embodiment embodies the steps of acquiring the subsequent voice and waking up the electronic device according to the voice recognition result of the subsequent voice. Therefore, according to the scheme described in this embodiment, on the basis of waking up the electronic device according to the pre-wake-up information, the matching step of the complete wake-up word is added, so that the technical effect of giving consideration to both the wake-up rate and the wake-up accuracy is achieved.
With further reference to fig. 5, as an implementation of the methods shown in the above-mentioned figures, the present application provides an embodiment of an apparatus for waking up an electronic device, where the embodiment of the apparatus corresponds to the embodiment of the method shown in fig. 2, and the apparatus may be specifically applied to various electronic devices.

The matched awakening word can contain a character string consistent with the first voice recognition result.
In some optional implementations of the present embodiment, the wake-up unit 505 may include an obtaining module (not shown in the figure) and a wake-up module (not shown in the figure). Wherein the obtaining module may be configured to obtain subsequent speech associated with the speech to be recognized in response to determining that the pre-wake information is used to characterize the pre-wake allowed. Wherein, the acquisition time of the subsequent voice can be later than the voice to be recognized.

The wake-up sub-module may be configured to wake up the electronic device in response to determining that the target speech recognition result is consistent with the matching wake-up word.
The apparatus provided in the above embodiment of the present application first acquires the speech to be recognized through the acquisition unit 501. Then, the recognition unit 502 recognizes the speech to be recognized, and generates a first speech recognition result. Next, the determining unit 503 determines whether a wakeup word including the first speech recognition result exists in a preset wakeup word set, wherein the number of characters included in the wakeup word is greater than the number of characters included in the first speech recognition result. Then, the generating unit 504 generates pre-wakeup information in response to determining that a wakeup word including the first speech recognition result exists in the preset wakeup word set.
