Voice calls described herein include, but are not limited to: a voice call performed through a voice call service in third-party application software, or a voice call performed through a voice call service provided by an operator, and the like.

As shown in fig. 1, the voice call method includes:

step 101: the method comprises the steps of obtaining a voice signal collected by at least one first device within a preset range.

The first device described herein is a device having a speech acquisition function, such as a device provided with microphone hardware. The first device may be a non-communication electronic device such as a home appliance.

The preset range described herein refers to a range of a certain place, such as a home range of a user. The first terminal can enumerate first equipment with a voice acquisition function in a preset range by means of an enumeration interface (named as IotAPI.

The voice signal is a voice signal sent by a target user, and the target user is a home terminal user in a voice call.

The state of voice call described herein may be a handsfree call state or the like.

In the embodiment of the invention, when the first terminal detects that the first terminal is in a voice call state, the first terminal acquires the voice signal of the target user, which is acquired by at least one first device within a preset range, so that in the subsequent steps, one device is determined in the first device according to the signal quality of the voice signal and is used as a microphone for acquiring the voice signal of the target user in the voice call.

Step 102: and determining the first equipment corresponding to the voice signal with the highest signal quality as first target equipment according to the signal quality of the voice signal acquired by the first equipment.

In this step, according to the signal quality of the voice signal acquired by each first device obtained instep 101, the voice signal with the highest signal quality is determined, and the first device corresponding to the voice signal with the highest signal quality (i.e., the first device acquiring the voice signal with the highest signal quality) is determined as the first target device, so as to be used in the voice call to acquire the voice signal of the target user.

Optionally, in this step, when analyzing the quality of the speech signal, parameters such as amplitude, frequency response, distortion degree, and signal-to-noise ratio of the speech signal may be weighted and calculated, so as to determine the signal quality of each speech signal.

Optionally, after the first target device is determined, other devices in the first device except the first target device may be controlled to stop acquiring the audio signal, so as to reduce power consumption of the device.

Step 103: and sending the voice signal collected by the first target device to the second terminal.

The second terminal is an opposite terminal of the voice call.

In the embodiment of the present invention, after the first target device is determined instep 102, the voice signal of the target user collected by the first target device is sent to the first terminal, and the voice signal of the target user collected by the first target device is sent to the opposite end of the voice call by the first terminal, so that the voice signal of the target user is sent in the voice call process.

In the embodiment of the invention, when a user is in voice communication, some electronic equipment with a voice acquisition function around can participate in the voice communication. The electronic equipment with good quality of collected voice signals is used as a microphone in the voice call process of the home terminal so as to collect the voice signals of the home terminal user. Therefore, the voice signal of the local terminal user can be collected without being limited by the first terminal while the call quality is ensured, more freedom of selection is provided for the voice call of the user, and the voice call of the user is facilitated. In addition, the surrounding non-communication electronic equipment can be fully utilized, and the utilization rate of the non-communication electronic equipment is improved.

Optionally, before acquiring the voice signal collected by at least one first device within the preset range instep 101, the method further includes: respectively acquiring a first audio signal acquired by each first device; matching the voiceprint of the first audio signal with a preset voiceprint; and if the voiceprint of the first audio signal is matched with the preset voiceprint, determining the first audio signal as the voice signal.

The preset voiceprint described herein is generated based on a pre-recorded voice signal of the target user.

Optionally, the first audio signal comprises at least one audio signal. The determining that the first audio signal is the speech signal if the voiceprint of the first audio signal matches the preset voiceprint includes: and determining the audio signal matched with the preset voiceprint in the first audio signal as the voice signal collected by the first equipment.

In the embodiment of the invention, when the first device acquires the voice signal of the target user, the first device may also acquire the sound generated by other sound sources such as other people and objects, so as to avoid the influence of the sound generated by other sound sources on the signal quality judgment of the voice signal; then, matching the voiceprint of each first audio signal with a preset voiceprint respectively; and finally, determining the audio signal matched with the preset voiceprint in the first audio signal as the voice signal acquired by the first equipment.

In the embodiment of the present invention, the principle of obtaining the voice signal of the target user acquired by the first device through the voiceprint is as follows:

since the vocal organs used by a person during speaking are very different from person to person in terms of size and shape, the vocal print maps of any two persons are different, and are mainly reflected in the following aspects:

a. the resonance mode is characterized in that: pharyngeal resonance, nasal resonance and oral resonance.

b. Voice purity characteristics: the different people's voices are generally of different purities, roughly classified into three grades of high purity (bright), low purity (dull) and medium purity.

c. Average pitch characteristics: the average sound level is said to be high or low voice.

d. The range characteristic: the level of the sound field is known as whether the sound is full or flat.

The distribution conditions of formants of different people's voices in a voiceprint spectrogram are different, and the voiceprint recognition is to judge whether the two voices are the same person or not by comparing the vocalization of the two voices on the same phoneme, so that the function of people's voice recognition is realized.

Optionally, when determining the first device corresponding to the voice signal with the highest signal quality, the signal quality of each voice signal may be compared with a preset signal quality, the voice signals with the signal quality greater than the preset signal quality are screened out, and then the first device corresponding to the voice signal with the highest signal quality is determined as the first target device from the screened out voice signals.

When the signal quality of all the voice signals is less than or equal to the preset signal quality, the voice signal with the highest signal quality can be screened out, and the voice signal is optimized in a mode of increasing the gain of the audio signal. The audio signal Gain can convert the received analog signal into a digital signal through an Automatic Gain Control (AGC) algorithm, and then the digital signal is converted into an analog signal through an amplification module.

The preset signal quality may be determined according to an experience threshold of a user, or may be a parameter value for ensuring the basic communication quality under big data.

Optionally, in the embodiment of the present invention, in addition to determining the first target device serving as the microphone in the home terminal voice call, a second target device serving as the speaker in the home terminal voice call may also be determined within a preset range, so that the target user can listen to the call voice of the peer user. The specific implementation mode can be as follows: detecting the state of the first terminal; and when the first terminal is detected to be in a call state, determining second target equipment in at least one second equipment within a preset range.

After the second target device is determined, the first terminal may send the received call voice of the user of the second terminal (i.e., the peer user) to the second target device, and play the call voice of the user of the second terminal through the second target device.

The second device described herein is a device having a voice playback function, such as a device provided with speaker hardware. The second device may be a non-communication electronic device such as a home appliance. The second target device is the same device or a different device than the first target device. When the second target device and the first target device are the same device, the device is indicated to have the voice acquisition function and the voice playing function.

In the embodiment of the invention, some surrounding electronic equipment with a voice acquisition function can participate in the voice call, and some surrounding electronic equipment with a voice playing function can also participate in the voice call, so that the playing of the call voice of the opposite-end user is not limited to the playing through the first terminal, more freedom of selection is provided for the voice call of the user, and the voice call of the user is facilitated. In addition, the surrounding non-communication electronic equipment can be fully utilized, and the utilization rate of the non-communication electronic equipment is improved.

Optionally, determining a second target device in at least one second device within the preset range includes: determining whether the first target device has a voice playing function; when the first target equipment has a voice playing function, determining the first target equipment as second target equipment; and when the first target equipment does not have the voice playing function, determining second equipment closest to the first target equipment as second target equipment according to the pre-stored distance between the equipment.

The pre-stored distance between the devices is a pre-stored distance between each first device and each second device.

The first target device is a device which collects the voice signal quality of the target user to the best, and shows that the first target device is closer to the target user, and the device closer to the target user should be selected for the convenience of listening to the call voice of the opposite-end user by the target user. When the first target device does not have the voice playing function, the second device closest to the first target device may be determined as the second target device according to the pre-stored distance between the devices.

Optionally, before thestep 101 acquires the voice signal acquired by at least one first device within the preset range, the method further includes: and searching the first equipment and the second equipment within a preset range, and establishing an equipment list according to a search result.

In the embodiment of the present invention, device lists may also be respectively established in advance for a first device and a second device within a preset range. When the device list is established, it may be determined whether a current location of the first terminal is a preset location (e.g., home). When the current location of the first terminal is a preset location, searching for a first device and a second device within a preset range, and respectively adding the searched names of the first device and the second device to corresponding device lists, for example, adding the name of the first device to the first device list, and adding the name of the second device to the second device list, so as to record the first device and the second device, so that the first device and the second device can be quickly determined through the device list during voice communication.

The first terminal can enumerate devices with a voice acquisition function and devices with a voice playing function in a preset range by means of an enumeration interface (named as IotAPI. It will be appreciated that the device list for the first device and the device list for the second device may also be established manually by the user.

Further, under the condition that the device list is established, when it is detected that the first terminal is in the voice call state, the signal quality of the voice signal can be obtained according to the voice signal acquired by the first device in the device list, and the first device corresponding to the voice signal with the highest signal quality is determined as the first target device.

Optionally, in the embodiment of the present invention, a switch may be set for the voice call method. When the switch is in an on state, when the current location of the first terminal is detected to be a preset location, the first device and the second device within a preset range are automatically searched. And the steps in the voice call method provided by the embodiment of the invention are executed when the switch is in the on state.

Optionally, after determining, according to the signal quality of the voice signal, the first device corresponding to the voice signal with the highest signal quality as the first target device, the signal quality of the voice signal acquired by the first target device may also be detected in real time or at regular time, and when the signal quality of the voice signal acquired by the first target device is lower than the preset signal quality, the device with the highest signal quality of the acquired voice signal is determined as the first target device in the first devices other than the current first target device.

In the embodiment of the invention, in order to ensure the voice call quality of the user, the signal quality of the voice signal acquired by the first target device can be detected in real time or at regular time. When the signal quality of the voice signal acquired by the first target equipment is lower than the preset signal quality, the other first equipment can be controlled to acquire the voice signal of the target user, and one equipment with the highest signal quality of the acquired voice signal is reselected as the first target equipment.

Further, according to the above-mentioned method for determining a second target device, a second target device may be re-determined for the user to use according to the re-determined first target device.

Optionally, before acquiring the voice signal collected by at least one first device within the preset range instep 101, the method further includes: receiving a call request; and when the call request is not answered within the preset time, sending a call prompt tone to a preset third target device, and playing the call prompt tone through the third target device.

The third target device is a device having a voice playing function, and the third target device may be a device preset by a user, and the third target device is generally in a state of playing sound for a long time and having a large volume.

In the embodiment of the invention, in order to remind the user of the incoming call, the incoming call prompt tone can be sent to the preset third target device when the call request lasts for the preset time and is not answered, and the incoming call prompt tone is played through the third target device, so that the problem that the user cannot find the incoming call in time and misses the incoming call due to the fact that the incoming call prompt tone of the first terminal is too small is solved.

Optionally, the first device and the second device in the embodiment of the present invention may be internet of things devices, and information interaction may be performed between the first device and the first terminal through an internet of things technology. If the internet of things equipment decodes the collected voice signals, digital signals are generated and sent to the first terminal through the internet of things technology, or the internet of things equipment receives the digital signals and converts the digital signals into analog voice signals which can be understood by human ears through a digital-to-analog conversion chip and then the analog voice signals are played.

The internet of things technology can be wireless communication technology such as bluetooth, WiFi or cellular mobile communication network (such as 2G, 3G, 4G, 5G, etc.).

In order to better understand the voice call method provided by the embodiment of the present invention, the following example is further explained.

As shown in fig. 3, a dotted rectangle represents a preset location range. The method comprises the steps that the mobile phone obtains Internet of things equipment with a microphone and/or loudspeaker function within a preset place range, and an equipment list is respectively established. When one piece of internet of things equipment has the microphone function and the loudspeaker function, the name of the piece of internet of things equipment is added to the two equipment lists respectively.

Step 202: when the mobile phone is in a voice call state, whether the mobile phone is in a hands-free call state is detected.

When the mobile phone is in the hands-free call state, it indicates that the user may not be convenient to hold the mobile phone for calling. When the mobile phone is in the receiver mode, the user can conveniently hold the mobile phone to receive the call.

Step 203: when the mobile phone is in a hands-free call state, the mobile phone matches the sound signals collected by each Internet of things device with a microphone function with the preset voiceprint respectively according to a pre-established device list, and selects the sound signals matched with the preset voiceprint from the sound signals.

Step 204: and comparing the signal quality of the screened voice signals with preset signal quality, and screening out the Internet of things equipment with the best signal quality and with the microphone function.

Step 205: the internet of things equipment with the microphone function and the best signal quality is controlled to be in a working state, voice signals of a target user are continuously collected, and other internet of things equipment with the microphone function is controlled to sleep.

Step 206: when a user moves within a preset place range, if the signal quality of a voice signal acquired by the Internet of things equipment with the microphone function in the working state is lower than the preset signal quality, other Internet of things equipment with the microphone function is awakened, the acquired voice signal quality of the Internet of things equipment with the microphone function is enabled to be optimal, the Internet of things equipment with the microphone function is in the working state, and the voice signal of a target user is acquired, so that the conversation quality of the user is guaranteed.
