In the prior art, a user cannot select the communication equipment with good quality of the sent voice signal to communicate, so that the probability of poor communication quality is high, and the communication experience is influenced.
In order to solve the above problems, an embodiment of the present invention provides a method for sending a call signal, where a microphone of a mobile terminal and a microphone of a vehicle-mounted bluetooth both simultaneously acquire a voice signal in a vehicle during a call, and the voice signals acquired by the two different methods can obtain a call signal meeting a preset amplitude condition, so that the call signal meets the preset amplitude condition, thereby ensuring the call quality of an opposite-end caller, reducing the probability of poor call quality, improving the call quality, and improving user experience.
Referring to fig. 2, a flow chart of a method for sending a call signal according to a first embodiment of the present invention is shown, where the method includes:
in the embodiment of the invention, the vehicle-mounted Bluetooth can be connected with the mobile terminal through a wireless technology, after the connection, audio signals such as conversation, music and the like of the mobile terminal can be wirelessly transmitted to the vehicle-mounted Bluetooth, and at the moment, the mobile terminal and the vehicle-mounted Bluetooth can execute functions such as conversation, music playing and the like.
In the embodiment of the invention, no matter the user selects the mobile terminal to carry out the call or the vehicle-mounted Bluetooth to carry out the call under the condition that the mobile terminal and the vehicle-mounted Bluetooth are in wireless connection, a microphone of the mobile terminal and a microphone of the vehicle-mounted Bluetooth simultaneously acquire the voice signals in the vehicle, and the mobile terminal acquires the first voice signal acquired by the microphone of the mobile terminal and the second voice signal acquired by the microphone of the vehicle-mounted Bluetooth.
in the embodiment of the invention, an amplitude threshold value is preset according to the lowest call requirement, and when the amplitude of the third voice signal is below the amplitude threshold value, the third voice signal is determined to be the third voice signal meeting the preset amplitude condition.
And step 203, sending the third voice signal to the opposite terminal as a call signal.
In the embodiment of the invention, the third voice signal is used as the call signal to be sent to the opposite terminal because the amplitude of the third voice signal meets the call requirement, so that the call quality of a caller at the opposite terminal can be ensured.
In the embodiment of the invention, under the condition that the mobile terminal and the vehicle-mounted Bluetooth are in wireless connection, a first voice signal acquired by a microphone of the mobile terminal and a second voice signal acquired by a microphone of the vehicle-mounted Bluetooth are acquired, a third voice signal meeting a preset amplitude value condition is determined according to the first voice signal and the second voice signal, and the third voice signal is used as a call signal and is sent to an opposite terminal. Compared with the prior art, when in conversation, the microphone of the mobile terminal and the microphone of the vehicle-mounted Bluetooth both simultaneously acquire the voice signal in the vehicle, the voice signal acquired by the two different modes can be used for acquiring the conversation signal meeting the preset amplitude condition, and the conversation signal meets the preset amplitude condition, so that the conversation quality of an opposite-end speaker is ensured, the probability of poor conversation quality is reduced, the conversation quality is improved, and the user experience is improved.
Referring to fig. 3, a flow chart of a method for sending a call signal according to a second embodiment of the present invention is shown, where the method includes:
in the embodiment of the present invention, the content of the step 301 is the same as that described in the step 201 in the first embodiment of the present invention, and is not described herein again.
in the embodiment of the present invention, the voice signal includes a voice of a caller, music, a whistle, etc., and the voice signal is analyzed to obtain voiceprint features of a plurality of sounds, and a first target voiceprint feature and a second target voiceprint feature are determined from the voiceprint features, wherein the first target voiceprint feature and the second target voiceprint feature are the same voiceprint feature and are both the voiceprint features of the caller at the local terminal.
Wherein, because the microphone of the mobile terminal and the microphone of the vehicle Bluetooth simultaneously collect the voice signals in the vehicle, the periods of the collected speech signals are the same, but the amplitudes may be different, so that the voiceprint characteristics of the sounds parsed from the first speech signal correspond to the frequencies of the voiceprint characteristics of the sounds parsed from the second speech signal, e.g., the voiceprint characteristics of the plurality of sounds obtained by analyzing the first voice signal comprise the voice characteristics of the first caller and the first music characteristics, the voiceprint characteristics of the plurality of sounds obtained by analyzing the second voice signal are the voice characteristics of the second speaker and the second music characteristics, the first speaker voice characteristic is the same frequency as the second speaker voice characteristic and is the same voiceprint characteristic, and the first music characteristic is the same frequency as the second music characteristic and is also the same voiceprint characteristic.
and step 305, sending the third voice signal to the opposite terminal as a call signal.
In the embodiment of the present invention, an absolute value of a difference between the first amplitude and the second amplitude is calculated, if the absolute value is less than or equal to a preset first threshold, an amplitude average value of the first amplitude and the second amplitude is calculated, and a speech signal corresponding to the amplitude average value is determined as a third speech signal.
Under normal conditions, the amplitude of the first voice signal collected by the microphone of the mobile terminal and the amplitude of the second voice signal collected by the microphone of the vehicle-mounted bluetooth are not different too much, so that the first amplitude of the sound belonging to the first target voiceprint feature and the second amplitude of the sound belonging to the second target voiceprint feature are not different too much, and during driving, the distance between the microphone of the mobile terminal and the microphone of the vehicle-mounted bluetooth may be changed due to the movement of the body position of the local terminal caller, so that the amplitude of the first voice signal collected by the microphone of the mobile terminal and the amplitude of the second voice signal collected by the microphone of the vehicle-mounted bluetooth are unstable, and the amplitude of the first amplitude of the sound belonging to the first target voiceprint feature and the amplitude of the second amplitude of the sound belonging to the second target voiceprint feature are also unstable, if the voice signal corresponding to the amplitude with the larger first amplitude value and the larger second amplitude value is determined as the third voice signal, the amplitude value of the third voice signal may be unstable, for example, the first threshold value is 10db, the first amplitude value in the current time duration is 42db, the second amplitude value is 36db, the first amplitude value in the next time duration is 34db, the second amplitude value is 36db, the absolute value of the first amplitude value and the second amplitude value in the current time duration is smaller than the first threshold value, the absolute value of the first amplitude value and the second amplitude value in the next time duration is also smaller than the first threshold value, if the voice signal corresponding to the amplitude value with the larger first amplitude value and the second amplitude value is determined as the third voice signal, the voice signal corresponding to the first amplitude value of 42db needs to be collected by the microphone of the mobile terminal in the current time duration is determined as the third voice signal, the voice signal corresponding to the second amplitude value of 36db needs to be collected by the microphone of the vehicle-mounted bluetooth in the next time duration is determined as the third voice signal, when the amplitude of the third voice signal is changed from 42db to 36db, 6db is changed once, and if the amplitude changes frequently, the voice information received by the opposite terminal is large and small, which affects the communication quality of the opposite terminal. Therefore, the voice signal corresponding to the average amplitude value is determined as the third voice signal, that is, the voice signal corresponding to (36+42)/2 ═ 39db in the current time length is determined as the third voice signal, the voice signal corresponding to (36+34)/2 ═ 35db in the next time length is determined as the third voice signal, and the rate of change in the amplitude of the current time length and the next time length is 4db, so that the change in the amplitude of the third voice signal is more gradual, and the third voice signal is transmitted to the opposite end as the call signal, so that the call quality of the opposite end can be ensured.
If the absolute value is larger than the first threshold, determining the amplitude with larger value in the first amplitude and the second amplitude, and determining the voice signal corresponding to the amplitude with larger value as the third voice signal.
In the embodiment of the present invention, if the absolute value is greater than the first threshold, it indicates that the difference between the first amplitude and the second amplitude is too large, and if the average value of the amplitudes of the first amplitude and the second amplitude is calculated again, the average value of the amplitudes is too small, and the voice signal corresponding to the average value of the amplitudes is determined as the third voice signal and sent to the opposite end, which may affect the call quality of the opposite end, for example, the first threshold is 10db, the first amplitude in the current time duration is 42db, and the second amplitude is 10db, the average value of the amplitudes is (42+10)/2 db, the voice signal corresponding to the amplitude 26db is determined as the third voice signal, and the third voice signal is sent to the opposite end as the call signal, so that the amplitude of the call signal received by the opposite end is too small, and the call quality is too small.
It should be noted that, if the absolute value is greater than the first threshold, the magnitude of the amplitude with the larger value is compared with a preset second threshold, and if the absolute value exceeds the second threshold, the amplitude is too large, which may cause a sound breaking phenomenon, and the call signal with the too large amplitude is transmitted to the opposite terminal, and the opposite terminal may hear the sound breaking, which affects the call quality, so that if the amplitude with the larger value is less than or equal to the second threshold, the voice signal corresponding to the amplitude with the larger value is determined as a third voice signal, and the third voice signal is transmitted to the opposite terminal as a call signal; if the amplitude value with the larger numerical value is larger than the second threshold value, amplitude reduction processing needs to be performed on the amplitude value of the voice signal, the voice signal refers to a voice signal corresponding to the amplitude value with the larger numerical value, the amplitude value of the voice signal is adjusted to be the third threshold value based on a preset third threshold value, the voice signal with the adjusted amplitude value is determined to be the third voice signal, and the third voice signal is sent to the opposite terminal as a call signal, so that the call signal received by the opposite terminal is not broken, and the call quality is improved.
Referring to FIG. 4, a flow chart of the step 302 of the embodiment shown in FIG. 3 is shown, which includes:
in the embodiment of the invention, the voices from different sources can be various persons or objects or equipment capable of generating voices, such as a caller, a television, an animal, a machine and the like, the voiceprint characteristics of the voices are main physical parameters of the voices, the voiceprint characteristics of the voices can be displayed by an electric instrument, the voiceprint characteristics of each voice are different, and the different voices can be determined through the voiceprint characteristics of the voices.
in the embodiment of the present invention, a voiceprint feature recognition library is preset in the mobile terminal, and includes voiceprint features of one or more users, for example, a voice signal of a local caller is obtained in advance, and the voiceprint features of the voice signal are stored in the mobile terminal of the local caller to serve as the preset voiceprint feature recognition library.
In the embodiment of the invention, because the microphone of the mobile terminal and the microphone of the vehicle-mounted Bluetooth simultaneously acquire the voice signals in the vehicle, the periods of the acquired voice signals are the same, but the amplitudes of the acquired voice signals may be different, so that the first voiceprint feature and the second voiceprint feature are the same voiceprint feature.
In the embodiment of the invention, during conversation, the microphone of the mobile terminal and the microphone of the vehicle-mounted Bluetooth simultaneously acquire the voice signal in the vehicle, analyze the first voice signal acquired by the microphone of the mobile terminal to acquire the first target voiceprint belonging to the local terminal caller, analyze the second voice signal acquired by the microphone of the vehicle-mounted Bluetooth to acquire the second target voiceprint belonging to the local terminal caller, determine the first amplitude of the sound belonging to the first target voiceprint characteristic in the first voice signal and the second amplitude of the sound belonging to the second target voiceprint characteristic in the second voice signal, and utilize the first amplitude and the second amplitude to acquire the conversation signal of which the amplitude meets the preset amplitude condition, so as to ensure the conversation quality of the opposite terminal caller, reduce the probability of poor conversation quality and improve the conversation quality, and the user experience is improved.

Under normal conditions, the amplitude of the first voice signal collected by the microphone of the mobile terminal and the amplitude of the second voice signal collected by the microphone of the vehicle-mounted bluetooth are not different too much, so that the first amplitude of the sound belonging to the first target voiceprint feature and the second amplitude of the sound belonging to the second target voiceprint feature are not different too much, and during driving, the distance between the microphone of the mobile terminal and the microphone of the vehicle-mounted bluetooth may be changed due to the movement of the body position of the local terminal caller, so that the amplitude of the first voice signal collected by the microphone of the mobile terminal and the amplitude of the second voice signal collected by the microphone of the vehicle-mounted bluetooth are unstable, and the amplitude of the first amplitude of the sound belonging to the first target voiceprint feature and the amplitude of the second amplitude of the sound belonging to the second target voiceprint feature are also unstable, if the voice signal corresponding to the amplitude with the larger first amplitude value and the larger second amplitude value is determined as the third voice signal, the amplitude value of the third voice signal may be unstable, for example, the first threshold value is 10db, the first amplitude value in the current time duration is 42db, the second amplitude value is 36db, the first amplitude value in the next time duration is 34db, the second amplitude value is 36db, the absolute value of the first amplitude value and the second amplitude value in the current time duration is smaller than the first threshold value, the absolute value of the first amplitude value and the second amplitude value in the next time duration is also smaller than the first threshold value, if the voice signal corresponding to the amplitude value with the larger first amplitude value and the second amplitude value is determined as the third voice signal, the voice signal corresponding to the first amplitude value of 42db needs to be collected by the microphone of the mobile terminal in the current time duration is determined as the third voice signal, the voice signal corresponding to the second amplitude value of 36db needs to be collected by the microphone of the vehicle-mounted bluetooth in the next time duration is determined as the third voice signal, when the amplitude of the third voice signal is changed from 42db to 36db, 6db is changed once, and if the amplitude changes frequently, the voice information received by the opposite terminal is large and small, which affects the communication quality of the opposite terminal. Therefore, the voice signal corresponding to the average amplitude value is determined as the third voice signal, that is, the voice signal corresponding to (36+42)/2 ═ 39db in the current time length is determined as the third voice signal, the voice signal corresponding to (36+34)/2 ═ 35db in the next time length is determined as the third voice signal, and the rate of change in the amplitude of the current time length and the next time length is 4db, so that the change in the amplitude of the third voice signal is more gradual, and the third voice signal is transmitted to the opposite end as the call signal, so that the call quality of the opposite end can be ensured.
If the absolute value is larger than the first threshold, determining the amplitude with larger value in the first amplitude and the second amplitude, and determining the voice signal corresponding to the amplitude with larger value as the third voice signal.
In the embodiment of the present invention, if the absolute value is greater than the first threshold, it indicates that the difference between the first amplitude and the second amplitude is too large, and if the average value of the amplitudes of the first amplitude and the second amplitude is calculated again, the average value of the amplitudes is too small, and the voice signal corresponding to the average value of the amplitudes is determined as the third voice signal and sent to the opposite end, which may affect the call quality of the opposite end, for example, the first threshold is 10db, the first amplitude in the current time duration is 42db, and the second amplitude is 10db, the average value of the amplitudes is (42+10)/2 db, the voice signal corresponding to the amplitude 26db is determined as the third voice signal, and the third voice signal is sent to the opposite end as the call signal, so that the amplitude of the call signal received by the opposite end is too small, and the call quality is too small.
It should be noted that, if the absolute value is greater than the first threshold, the magnitude of the amplitude with the larger value is compared with a preset second threshold, and if the absolute value exceeds the second threshold, the amplitude is too large, which may cause a sound breaking phenomenon, and the call signal with the too large amplitude is transmitted to the opposite terminal, and the opposite terminal may hear the sound breaking, which affects the call quality, so that if the amplitude with the larger value is less than or equal to the second threshold, the voice signal corresponding to the amplitude with the larger value is determined as a third voice signal, and the third voice signal is transmitted to the opposite terminal as a call signal; if the amplitude value with the larger numerical value is larger than the second threshold value, amplitude reduction processing needs to be performed on the amplitude value of the voice signal, the voice signal refers to a voice signal corresponding to the amplitude value with the larger numerical value, the amplitude value of the voice signal is adjusted to be the third threshold value based on a preset third threshold value, the voice signal with the adjusted amplitude value is determined to be the third voice signal, and the third voice signal is sent to the opposite terminal as a call signal, so that the call signal received by the opposite terminal is not broken, and the call quality is improved.
