Detailed ways

The technical solutions of the present application will be described below with reference to the accompanying drawings.

For ease of understanding, the related concepts involved in this application are briefly introduced.

The TeleTYpe (TTY) service or the Text Telephone Devices for the Deaf (TDD) service is a mobile "voice" service for deaf people. TTY services or TDD services can generally support three TTY function modes: Full mode (also called TTY mode), Voice Carry Over (VCO) mode, and Hearing Carry Over (HCO) mode. The TTY mode supports sending and receiving TTY text at the same time. In the TTY mode, when the terminal device is connected to the TTY device, only the character transmission can be performed and the call cannot be made. When the connection between the terminal device and the TTY device is disconnected, the terminal device can normally talk with other terminal devices. In the VCO mode, the terminal device can switch between receiving TTY text and transmitting voice, mainly for 聋. In the HCO mode, the terminal device can switch between sending TTY text and answering a call, mainly for dumb.

TTY devices work similarly to TDD devices. The following only describes TTY devices as an example.

The following is a brief description of the working principle of the TTY device.

Figure 1 is a schematic diagram of the working principle of the TTY device. Referring to Figure 1, the existing TTY solution requires a dedicated TTY device to connect to a terminal device. When the user connects the session on the terminal device, text input and display can be performed on the TTY device to implement communication with the peer.

The use of the TTY device can be roughly expressed as follows: The TTY device provides a 3.5 mm audio connector for connection with the terminal device. If the audio connector of the terminal device does not match the audio connector provided by the TTY device, it can be converted by a patch cord.

The working principle of the TTY device and the TDD device are similar. To avoid the cumbersome description, the following describes the TTY device as an example.

2 is a structural block diagram of a TTY device. As shown in Figure 2, the implementation of the TTY service mainly includes two parts: an encoder and a decoder. The encoder is responsible for detecting a Baudot tone transmitted on a Pulse Code Modulation (PCM) link and parsing it into corresponding TTY character information for transmission to the decoder. After receiving the TTY character information, the decoder is responsible for restoring the TTY character information to the corresponding Bode tone.

The FER in Fig. 2 represents a frame error rate (FER).

The existing TTY device has a high purchase cost, and since the communication between the TTY device and the terminal device is transmitted through an analog signal, signal loss and distortion are inevitable in the process of signal transmission, processing, and conversion, and thus error The code rate is also higher. In addition, the weight and volume of the TTY device are generally large and inconvenient to carry.

To this end, the present application provides a method for implementing voice communication, which can avoid a high bit error rate when using a conventional TTY hardware device. Inconvenience such as carrying.

In the embodiment of the present application, by running an application software having a function of converting between text and voice on a terminal device, the user can implement voice communication by using the application software.

In the embodiment of the present application, the application software running on the terminal device that implements the function of converting between text and voice needs to acquire the same authority as the call module on the terminal device. In order to facilitate the succinctness of the description, in the following, we will write the software running on the terminal device with the function of realizing the conversion between text and voice as the first application.

It should be noted that, the first application mentioned in the embodiment of the present application is different from the data service-based application (for example, WeChat), and the first application mentioned herein is based on voice service. Or, the first application needs to be based on a real-time communication network. Moreover, the voice service is a function supported by all carrier networks, so any area with signal coverage can be used.

In addition, the first application in this article needs to have the same privileges as a normal call. This requires a high level of authorization due to user privacy. Taking the Android operating system as an example, the first application requires an Android installation package (Android Package, APK) to interact with the underlying driver software, and the underlying driver software can only be modified by the original equipment manufacturer (OEM). Therefore, this application The first application in the embodiment is not suitable for a third party to provide separately.

The voice communication method provided by the present application can be applied to various scenarios. For example, a terminal device running a first application communicates with a legacy TTY device. Alternatively, communication between the terminal device running the first application and the terminal device is performed.

Referring to FIG. 3, FIG. 3 is a schematic flowchart of a method 300 for voice communication provided by the present application.

It should be noted that the terminal device that performs the method 300 needs to run the first application, and at least should also have a voice transmission module. Among them, the first application is an application software, which needs to have the function of converting text and voice to each other. The voice transmission module can communicate with the first application to send the application output by the first application to other terminal devices that perform voice communication with the terminal device. Alternatively, the voice transmission module may send the voice data sent by the other terminal device to the first application, so that the voice data is converted into text information by the first application.

It can be understood that the mutual conversion between the text information and the voice can be realized through the first application on the terminal device. In this way, if the user using the terminal device is a deaf or hearing impaired person, the terminal can support the sending and receiving of text, thereby helping the deaf or hearing impaired person to perform normal voice communication.

310. The first application on the terminal device obtains text information for input.

The user can use various input methods for text input based on the operating system running on the terminal device.

Further, the terminal device can provide modes such as "only hear HCO", "just say no listening to VCO" and "FULL" for the user to select. A description of these modes can be found above.

In the "speak only" mode, the user can enter the text to be sent on the interface of the first application. The text entered by the user can be displayed in real time on the interface of the first application. In the "just say no listening" mode, users can also input by voice or text. In the FULL mode, the user can input the text to be sent on the interface of the first application, and the information sent by the other party is received by the user by displaying the text on the first application interface.

320. The first application converts the text information into voice data.

The first application can convert the text information into voice data. For example, the first application can encode the text input by the user number based on the TTY protocol to obtain voice data.

330. The first application sends the voice data to the voice transmission module.

340. The voice transmission module sends the voice data to other terminal devices that perform voice communication with the terminal device.

In the process of the user inputting text in real time, the first application can convert the text input by the user into voice data in real time, and send the voice data to the voice transmission module. The voice transmission module on the terminal device is responsible for transmitting voice data over the cellular network to other terminal devices that perform voice communication with the terminal device.

For convenience of description, we refer to the terminal device described in steps 310-340 as the first terminal device. Other terminal devices that perform voice communication with the first terminal device are referred to as second terminal devices.

After the voice transmission module on the second terminal device receives the voice data from the first terminal device, the voice transmission module sends the voice data to the first application on the second terminal device. The first application on the second terminal device converts the voice data into text information. In this way, the user using the second terminal device can receive the text information sent by the first terminal device. Since the text information input by the user can be converted into voice data in real time, real-time communication and communication between the two parties of the voice communication is realized.

Compared with the traditional TTY device, the process of converting the text information and the voice data input by the user is realized by the first application, that is, the processing of the digital signal is no longer involved, and the analog signal and the digital signal are no longer involved. The conversion between them can thus reduce the bit error rate. At the same time, the user no longer needs to carry the TTY device with him, and the voice communication and communication can be realized through the first application on the terminal device, thereby avoiding the disadvantage that the TTY device is inconvenient to carry.

Referring to FIG. 4, FIG. 4 is an application scenario of a voice communication method applicable to an embodiment of the present application.

401. The first application on the terminal device A obtains text information input by the user.

For example, the first application gets the text entered by the user as "Long time no see, is it good recently?"

402. The first application converts text input by the user into voice data.

In the process of the user inputting the text in real time, the first application running on the terminal device A directly encodes the text input by the user into the voice data conforming to the TTY protocol according to the TTY protocol.

In step 402, the encoded speech data is a digital signal.

403. The first application sends the voice data to the voice transmission module. The voice transmission module receives the voice data sent by the first application, and modulates the voice data and sends the voice data.

For example, the voice transmission module can be a modulation module (Modem). The first application sends the encoded voice data to the modulation module on the terminal device A. The modulation module modulates the voice data into an analog signal and sends the voice data to the operator network, and the operator network sends the analog signal to the terminal device B.

In the process of sending an analog signal, if an abnormal situation occurs (for example, network failure, dropped network), the modulation module will send feedback information to terminal device A in real time. The receiver on the terminal device A forwards the received information to the first application, and the first application displays the prompt information on the interface to prompt the user.

In the VCO mode, the first application performs text prompts on the software interface, for example, displays prompts such as "will resend the input text", "network exception, please wait a little". In the HCO mode, the first application can perform voice prompts, or both voice prompts and text prompts.

404. The terminal device B receives the analog signal sent by the terminal device A, and obtains voice data after demodulation.

The voice transmission module on the terminal device B receives the analog signal from the terminal device A, and demodulates the analog signal to obtain voice data. The voice data at this time is a digital signal.

405. The first application on the terminal device B converts the voice data into text information.

In steps 404-405, after receiving the analog signal, the terminal device B first demodulates the analog signal into a digital signal. The digital signal is then forwarded to the first application running on terminal device B. The first application decodes the digital signal (ie, voice data) based on the TTY protocol to obtain the decoded text.

For example, the decoded text of the first application on the terminal device is "Long time no see, is it good recently?"

Further, the terminal device may further include a display module.

406. The display module on the terminal device B displays the decoded text information in real time.

Specifically, the display module displays the text "Long time no see, is it good recently?" in real time on the interface of the first application.

In step 406, the terminal device B may have a preset number of data packets (eg, 10) buffers and display text at a set speed to avoid network fluctuations that may result in a poor user experience.

The above-mentioned FIG. 4 uses the voice communication method provided by the present application as the application scenario, that is, both parties performing voice communication run the first application on the terminal device, and the first application performs the mutual conversion between the text and the voice. In another application scenario, the party in the call uses the voice communication method provided by the present application, and the other party to the call can continue to use the traditional TTY device.

As mentioned above, the communication between the traditional TTY device and the terminal device requires a lot of analog-to-digital converter (ADC) and/or digital-to-analog converter (DAC). The process, in the course of the ADC/DAC, will inevitably cause distortion and loss of the signal, resulting in a higher bit error rate.

Referring to FIG. 5, FIG. 5 is another application scenario applicable to the voice communication method provided by the present application. As shown in FIG. 5, the terminal device C adopts the voice communication method in the embodiment of the present application, and the terminal device C runs the first application. The terminal device D is connected to a conventional TTY device. Since the TTY device involves the mutual conversion between the analog signal and the digital signal in the processing and transmission of the data packet, the bit error rate is high. Therefore, the terminal device C may receive an error in the data packet transmitted by the terminal device D. The present application is specifically directed to such an application scenario, and it is proposed that the first application on the terminal device C can perform error correction on data packets from other terminal devices.

Specifically, after receiving the voice data sent by the terminal device D, the voice transmission module on the terminal device C sends the voice data to the first application on the terminal device C. The first application decodes the voice data based on the TTY protocol, and converts the voice data into text information. Thereafter, the first application can correct the decoded text information to obtain the corrected text. Finally, the corrected text is displayed by the display module on the terminal device C.

Furthermore, error correction of the data packet can also be performed by other applications on the terminal device than the first application. For example, an expert system capable of self-learning is run on the terminal device C, and the first application sends the decoded text information to the expert system, and the expert system performs error correction (or error correction) on the text information. .

In the embodiment of the present application, the function of the expert system is to perform secondary correction on the decoded text (for example, text correction in word text). This is an alignment correction method based on an existing font library. The system can compare the decoded text with the existing text in the font library by means of fuzzy matching. If the decoded text is not found in the text library, mark it out and give the suggested text the closest.

For example, after "hello" is deformed to "helle" due to network or other reasons, the expert system can add a wavy line under "helle" and give the closest word "hello".

Because it is based on the contrast correction of the font library, and the font library is in fact constantly updated, the font library can be upgraded with the upgrade of the operating system running on the terminal device to enhance the correction capability.

Take the Android operating system as an example, the text library can be continuously upgraded following the upgrade of the APK.

It can be understood that since the expert system is an application software running on the terminal device, the central server can perform push upgrade at any time to enhance the error resistance capability of the expert system.

Alternatively, the expert system in the embodiment of the present application can also be understood as an application software having a text correction function. In a specific implementation, the function of the expert system can be integrated on the first application, or can also be interacted with the first application. The embodiments of the present application are not limited in any way.

The voice communication method provided by the present application is described in detail above with reference to FIG. 3 to FIG. 5. It can be seen that, in the embodiment of the present application, by softwareizing the function of the TTY device, the problem that the bit error rate is high and the portability is inconvenient when using the traditional TTY device can be avoided.

In addition, the deaf-mute person will no longer be limited to the hardware TTY device with high cost of purchase, and the terminal device designed according to the voice communication method according to the embodiment of the present application can reduce the purchase cost.
