An embodiment of the present invention provides an automatic voice call switching method, and referring to fig. 2, fig. 2 is a flowchart of a first embodiment of the automatic voice call switching method according to the present invention.
In this embodiment, the method for automatically switching voice calls includes the following steps:
step S10: when a voice call is started, acquiring a user voice signal in the surrounding environment;
it should be noted that the execution subject of this embodiment is an intelligent terminal device, such as a mobile phone or a tablet, and may also be other devices having the same or similar functions.
It can be understood that the terminal intelligent device is generally provided with a microphone, and when the voice call function of the intelligent terminal is started, the microphone can collect a user voice signal.
In specific implementation, taking a mobile phone as an example, two microphones are respectively arranged at the bottom and the top of the mobile phone, the microphone at the bottom is a main microphone and is mainly used for collecting sound signals, and the microphone at the top is an auxiliary microphone and is mainly used for noise reduction and noise elimination.
Further, in order to accurately collect the user voice signal in the surrounding environment, the step S10 includes: when a voice call is started, acquiring voice signals in the surrounding environment; and acquiring a sound source distance corresponding to the voice signal, and selecting a user voice signal from the voice signal according to the sound source distance.
It can be understood that the environment of the user during the voice call is complex and various, and it is possible that in a shopping mall, a station or other noisy environment, the microphone collected voice signal not only includes the user voice signal, but also has an interference signal in the environment.
It should be understood that terminal intelligent equipment is generally provided with a distance sensor, can perceive the distance between other objects and the equipment, combines the sound signal collected by a microphone, can obtain the sound source distance corresponding to the sound signal, and selects the sound source closest to the equipment in each sound source distance as the user voice signal.
Step S20: determining the sound energy corresponding to the user voice signal through a preset sound energy calculation algorithm;
it can be understood that the preset sound energy calculation algorithm is an algorithm for converting the user voice signal collected by the microphone into corresponding sound energy.
Step S30: and determining a target output mode of the voice call according to the sound energy, and switching the current output mode of the voice call to the target output mode.
It should be understood that the sound energy may reflect the intensity of the sound, and the determination of how the voice call outputs the audio ensures the current call quality is based on the sound energy.
Further, in order to improve the safety and convenience of switching the audio output mode during the voice call, the step S30 includes: judging whether the sound energy is larger than a preset energy threshold value or not; when the sound energy is larger than a preset energy threshold value, judging that a target output mode of the voice call is a first output mode; and if the current output mode of the voice call is the second output mode, switching the current output mode of the voice call to the first output mode.
It can be understood that the preset energy threshold is the sound energy when the user normally uses the receiver to perform voice call, and can be calculated by a laboratory to obtain the sound energy which is pre-stored in a local storage, so that the use habit of the user can be counted in the subsequent use, and the preset energy threshold is automatically updated.
It should be understood that the sound energy is greater than the preset energy threshold, so that it can be determined that the loudness of the sound output by the intelligent terminal device is not strong enough to ensure the call quality.
In a specific implementation, taking a mobile phone as an example, the first output mode may be a receiver output, the second output mode may be a speaker output, when the sound energy is greater than a preset energy threshold, the target output mode is the receiver output, and if the audio output mode of the current mobile phone voice call is the speaker output, the target output mode is automatically switched to the receiver output.
Further, in order to improve the safety and convenience of switching the audio output mode in the voice call process, after the step of determining whether the sound energy is greater than the preset energy threshold, the method further includes: when the sound energy is smaller than a preset energy threshold value, judging that the target output mode of the voice call is a second output mode; and if the current output mode of the voice call is the first output mode, switching the current output mode of the voice call to the second output mode.
It can be understood that, if a mobile phone is taken as an example, the first output mode may be a receiver output, the second output mode may be a speaker output, when the sound energy is smaller than the preset energy threshold, it indicates that the distance of sound source amplitude propagation is greatly attenuated, and the target output mode is the speaker output, but in the actual use process, there is a case that the current output mode of the voice call is already the speaker output, and at this time, the current output mode is kept unchanged, and when the current output mode of the voice call is the receiver output, the current output mode is automatically switched to the speaker output.
In a specific implementation, taking a mobile phone as an example, a main microphone of the mobile phone collects sound signals in a surrounding environment, a distance sensor of the mobile phone is combined, a user speech signal is selected from the collected sound signals, sound energy corresponding to the user speech signal is determined through a preset sound energy calculation algorithm, the sound energy is compared with a preset energy threshold, when the sound energy is greater than the preset energy threshold, if an output mode of a current speech call audio is a speaker output, the current speech call audio is automatically switched to a receiver output, and when the sound energy is less than the preset energy threshold, if the output mode of the current speech call audio is a receiver output, the current speech call audio is automatically switched to a speaker output.
In the embodiment, when the voice call is started, the voice signals of the user in the surrounding environment are collected; determining the sound energy corresponding to the user voice signal through a preset sound energy calculation algorithm; the target output mode of the voice call is determined according to the sound energy, the current output mode of the voice call is switched to the target output mode, and the target output mode of the voice call can be determined and automatically switched according to the sound energy in the voice call process because the embodiment collects the voice signals in the surrounding environment, selects the user voice signals from the voice signals, converts the collected user voice signals into the sound energy according to the preset sound energy calculation algorithm, and determines the output mode of the voice call according to the sound energy.
