The present application will be described below in detail with reference to the accompanying drawings and in combination with the embodiments.

FIG. 1 shows an exemplary architecture of a system 100 which may be used by a method and apparatus for voice input according to an embodiment of the present application.

As shown in FIG. 1, the system architecture 100 may include terminal device 101, a network 102 and a server 103. The network 102 serves as a medium providing a communication link between the terminal device 101 and the server 103. The network 102 may include various types of connections, such as wired or wireless transmission links, or optical fibers.

The user 110 may use the terminal device 101 to interact with the server 103 through the network 102, in order to transmit or receive messages, etc. Various communication client applications, such as input method applications, search engine applications, instant messaging tools, social platform software, may be installed on the terminal device 101.

The terminal device 101 may be various electronic devices supporting voice input function, including but not limited to smart phones, tablet computers, laptop computers, desktop computers, etc. Specifically, the terminal device 101 may first recognize the volume value of a voice input by the user in the voice input mode, then present to the user prompt information for prompting the user to control the volume value of the currently input voice, if the recognized volume value is not within the preset volume value range, and finally send the voice input by the user in a preset mode to the server 103, in the case where an instruction to end the voice input sent by the user is received.

The server 103 may be a backend server for various client applications installed on the terminal device 101. The backend server may process, such as analyze the voice output in the preset mode received from the terminal device 101 and feed the processing result (e.g., a webpage corresponding to the voice output in the preset mode) back to the terminal device 101, or send the processing result (e.g., the voice output in the preset mode) to other terminal devices that communicates with the terminal device 101.

It should be noted that the voice input method provided by the embodiments of the present disclosure is generally executed by the terminal device 101, accordingly, the voice input apparatus is generally provided in the terminal device 101.

It should be appreciated that the numbers of the terminal devices, the networks and the servers in FIG. 1 are merely illustrative. Any number of terminal devices, networks and servers may be provided based on the actual requirements.

With further reference to FIG. 2, a flow 200 of an embodiment of the voice input method according to the present disclosure is illustrated. The voice input method includes the following steps:

Step 201, switching, in response to detecting an instruction to start a voice input mode, a current input mode of an input method application to the voice input mode.

In the present embodiment, an electronic device (e.g., the terminal device 101 as illustrated in FIG. 1) on which the voice input method operate may detect instructions input by the user to start various input modes, and switch the current input mode of the input method application to the voice input mode, in the case where an instruction to start the voice input mode is detected. Here, the input method application may include a plurality of input modes, for example, the Pinyin input mode, the Five-stroke input mode, the handwriting input mode, the voice input mode, etc.

Typically, a preset switching key may be set on the visual interface of the input method application. The user may operate the preset switching key, thus triggering the input method application to send the instruction to start the voice input mode to the voice input engine, in order to switching the current input mode of the input method to the voice input mode. Here, the preset switching key may include but is not limited to a physical switching key, a virtual switching key, etc.

It should be noted that the input method application may be an input method application that comes with the terminal device, also may be a third party input method application installed by the user on the terminal device. The present embodiment is not limited to a specific input method application.

Step 202, recognizing a volume value of a voice input by a user in the voice input mode.

In the present embodiment, the electronic device may recognize the volume value of the voice input by the user in the voice input mode, in the case where the current input mode of the input method application is the voice input mode.

Typically, a preset voice input key may be set on the visual interface of the input method application. The user may input voice while touching or pressing the preset voice input key, meanwhile the electronic device may recognize the volume value of the voice input by the user in real time. Here, the preset voice input key may include but is not limited to a physical voice input key, a virtual voice input key, etc.

In the present embodiment, the volume value of the voice may be represented in a plurality of ways, for example, the volume value of the voice may be represented by a decibel value.

Step 203, determining whether the recognized volume value is within a preset volume value range.

In the present embodiment, based on the volume value recognized in step 202, the electronic device may determine whether the recognized volume value is within the preset volume value range. For example, the electronic device may compare the recognized volume value with the maximum value and/or the minimum value of the preset volume value range. If the recognized volume value is greater than the maximum value of the preset volume value range and/or less than the minimum value of the preset volume value range, it is determined that the recognized volume value is not within the preset volume value range. Otherwise, it is determined that the recognized volume value is within the preset volume value range.

Typically, the preset volume value range may be set by default. For example, the preset volume value range may be set to between 25 and 40 dB in the case where the voice input by the user does not interfere with the surrounding environment and can be accurately recognized.

Step 204, presenting to the user prompt information for prompting the user to control the volume value of the currently input voice, if the recognized volume value is not within the preset volume value range.

In the present embodiment, if the recognized volume value is not within the preset volume value range, the electronic device may present prompt information to the user. Here, the prompt may be used to prompt the user to control the volume value of the currently input voice. For example, if the recognized volume value is greater than the maximum value of the preset volume value range, a prompt to reduce the volume value of the currently input voice is presented to the user. The user may properly reduce the volume of the currently input voice according to the prompt to ensure that the user does not interfere with the surrounding environment when inputting voice. If the recognized volume value is smaller than the minimum value of the preset volume value range, a prompt to increase the volume value of the currently input voice is presented to the user. The user may properly increase the volume of the currently input voice according to the prompt to ensure that the voice input by the user can be accurately recognized.

In some alternative implementations of the present embodiment, the prompting mode of the prompt may include but is not limited to at least one of the following: a vibration prompt, a ringtone prompt, a voice prompt and a text prompt. For example, the electronic device may present a text prompt to prompt the user to increase or reduce the volume value of the currently input voice on the visual interface of the input method application, when the recognized volume value is not within the preset volume value range.

Alternatively, in order to avoid the text prompt affecting the user's regular voice input, the text prompt may automatically disappear after displaying a preset time on the visual interface of the input method application. For example, the text prompt disappears automatically after displaying 1 s on the visual interface of the input method application.

Step 205, outputting, in response to receiving an instruction to end the voice input, the voice input by the user in the voice input mode in a preset mode.

In the present embodiment, the electronic device may output the voice input by the user in the voice input mode in the preset mode, in the case where the electronic device receives an instruction to end the voice input sent from the user. Generally, the electronic device may assume that the user has finished the present voice input, in the case where the user stops touching or pressing the preset voice input key.

In some alternative implementations of the present embodiment, the electronic device may output a text matching the voice input by the user converted from the voice input by the user in the voice input mode. For example, the electronic device may first perform a voice recognition to the voice input by the user to generate a text matching the voice input by the user, and then send the text matching the voice input by the user to the corresponding backend server.

In some alternative implementations of the present embodiment, the electronic device may output the voice input by the user in the voice input mode, after amplifying the volume of the voice. For example, the electronic device may first amplify the volume of the voice input by the user, and then send the amplified voice to the corresponding backend server, so that the corresponding backend server sends the amplified voice to other electronic devices that communicate with the electronic device.

In some alternative implementations of the present embodiment, the electronic device may directly output the voice input by the user in the voice input mode. For example, the electronic device may directly send the voice input by the user to the corresponding backend server, so that the corresponding backend server sends the voice to other electronic devices that communicate with the electronic device.

The present disclosure also provides an application scenario of the voice input method according to the present embodiment. First, the user initiates an instruction to start the voice input mode. The electronic device may switch the input mode of the input method application to the voice input mode. As shown in FIG. 3a, the voice input interface may be presented on the screen of the electronic device. Then, the electronic device may recognize the volume value of the voice input by the user in the voice input mode and determine whether the recognized volume value is within the preset volume value range. In the case where the recognized volume value is greater than the maximum value of the preset volume value range, as shown in FIG. 3b, a text prompt “please reduce the volume value of the input voice” may be presented on the voice input interface. Finally, in the case where the user sends an instruction to end the voice input, the electronic device may perform a voice recognition to the voice input by the user in the voice input mode to generate a text “which input method application is better?” matching the voice input by the user. As shown in FIG. 3c, the text “which input method application is better?” may be presented in the search box of the voice input interface, and the electronic device may also send the text “which input method application is better?” to the background server of the search engine application, in the case where the user clicks on the search key.

By recognizing the volume value of the voice input by the user in the voice input mode, determining whether the recognized volume value is within the preset volume value range, then presenting to the user prompt information for prompting the user to control the volume value of the currently input voice in the case where the recognized volume value is not within the preset volume value range, and finally outputting the voice input by the user in the voice input mode in the preset mode in the case where an instruction to end the voice input is received, the voice input method provided by the above embodiment of the present disclosure realizes the effective control to the volume value of the voice input by the user in the voice input mode, effectively reduces the occurrences of situations such as the interference to the surrounding environment, the incorrect or the unrecognisable voice recognition, when the user adopts the voice input mode for voice inputting.

With further reference to FIG. 4, a flow 400 of another embodiment of the voice input method is illustrated. The flow 400 of the voice input method includes the following steps:

Step 401, switching, in response to detecting an instruction to start a voice input mode, a current input mode of an input method application to the voice input mode.

In the present embodiment, an electronic device (e.g., the terminal device 101 as illustrated in FIG. 1) on which the voice input method operate may detect instructions input by the user to start various input modes, and switch the current input mode of the input method application to the voice input mode, in the case where an instruction to start the voice input mode is detected.

Step 402, recognizing a volume value of a voice input by a user in the voice input mode.

In the present embodiment, the electronic device may recognize the volume value of the voice input by the user in the voice input mode, in the case where the current input mode of the input method application is the voice input mode.

Step 403, generating a waveform matching the recognized volume value based on the recognized volume value, and displaying the waveform in an input area of the input method application.

In the present embodiment, the electronic device may generate a waveform matching the recognized volume value, based on the volume value recognized in step 402, and display the waveform in the input area of the input method application. Generally, the abscissa of the waveform is time and the ordinate is the volume value.

Step 404, determining whether an amplitude of the waveform exceeds a target area.

In the present embodiment, the electronic device may determine whether the amplitude of the waveform exceeds the target area, based on the waveform matching the recognized volume value generated in step 403. Here, the amplitude of the waveform is the ordinate of each moment, and the target area is an area pre-partitioned in the input area matching the preset volume value range. Generally, the range of the target area is jointly defined by the upper limit indication line and the lower limit indication line of the target area. The upper limit indication line corresponds to the maximum value of the preset volume value range, and the lower limit indication line corresponds to the minimum value of the preset volume value range.

In the present embodiment, the electronic device may determine whether the amplitude of the waveform exceeds the target area. If the crest of the waveform crosses the upper limit indication line of the target area, step 405a is performed; if the trough of the waveform crosses the lower limit indication line of the target area, the 405b is performed. Here, the crest is the maximum value of the amplitude, and the trough is the minimum value of the amplitude.

Step 405a, presenting to the user prompt information for prompting the user to reduce the volume value of the input voice, if a crest of the waveform crosses an upper limit indication line of the target area.

In the present embodiment, based on the determined result of step 404, the electronic device may present prompt information for reducing the volume value of the currently input voice, in the case where the crest of the waveform crosses the upper limit indication line of the target area. The user may properly reduce the volume of the currently input voice according to the prompt to ensure that the user does not interfere with the surrounding environment when inputting voice. Here, the upper limit indication line corresponds to the maximum value of the preset volume value range.

Step 405b, presenting to the user prompt information for prompting the user to increase the volume value of the input voice, if a trough of the waveform crosses a lower limit indication line of the target area.

In the present embodiment, based on the determined result of step 404, the electronic device may present prompt information for increasing the volume value of the currently input voice, in the case where the trough of the waveform crosses the lower limit indication line of the target area. The user may properly increase the volume of the currently input voice according to the prompt to ensure that the voice input by the user can be accurately recognized. Here, the lower limit indication line corresponds to the minimum value of the preset volume value range.

Step 406, outputting, in response to receiving an instruction to end the voice input, the voice input by the user in the voice input mode in a preset mode.

In the present embodiment, the electronic device may output the voice input by the user in the voice input mode in the preset mode, in the case where the electronic device receives an instruction to end the voice input sent by the user.

As can be seen from FIG. 4, the flow 400 of the voice input method in the present embodiment, as compared with the corresponding embodiment in FIG. 2, highlights the step of determining whether the recognized volume value is within the preset volume value range based on whether the amplitude of the waveform corresponding to the recognized volume value exceeds the target area. Thus, the solution described in the present embodiment can display more vividly and intuitively to the user whether the recognized volume value is within the preset volume value range.
