Description

Mobile communication method capable of increasing the clarity of communication content

The invention relates to a mobile communication method, in particular to a mobile communication method capable of increasing the recognition of communication content.

With the development of technology, mobile communication devices such as mobile phones, personal digital assistants (PDAs), tablets or notebook computers allow users to make calls anytime, anywhere. Before the call or during the call, the user can adjust the volume of the loudspeaker of the mobile communication device according to his or her preference or the environment. In the prior art mobile communication method, if the environment of the Talker user is quite noisy, in order to hear the voice of the Talker user, the user of the receiving terminal may increase the volume of the loudspeaker of the mobile communication device. However, it will simultaneously amplify the voice of the whispering user and the noise of the whispering user's environment, so it is still impossible to clearly understand the communication content that the Talker user wants to convey.

On the other hand, after the speaker volume is turned up, the user usually does not turn the volume back to the normal volume after ending the call. Therefore, when the next call is answered, if the user is in a quiet environment, the volume of the loudspeaker may be scared to the user or to the people around, so the loudspeaker must be manually adjusted to the appropriate volume, so Prior art mobile communication methods often cause inconvenience.

The present invention provides a communication method for increasing the clarity of a communication content, comprising: a calling terminal device analyzing one of the received audio signals according to a first reference signal to identify a first voice signal and a first background signal When it is determined that the volume of the first voice signal is lower than a first threshold value, the calling device automatically increases the volume of the first voice signal according to a first adjustment parameter; The calling device sends the adjusted audio signal to a receiving device; the receiving device detects a second background signal when receiving the audio signal; and when determining that the audio signal has a volume lower than the first When the volume of the background signal exceeds a second threshold, the receiving device automatically increases the volume of the audio signal according to a second adjustment parameter.

Figure 1 is a flow chart showing the operation of a mobile communication method in the present invention. The mobile communication method of the present invention can be applied to a calling terminal device and a receiving terminal device, wherein the calling terminal device and the receiving terminal device can be the same or different types of communication such as a mobile phone, a personal digital assistant, a tablet computer or a notebook computer. Device. It should be noted that the types of the terminating device and the terminating device do not limit the scope of the present invention.

Step 190: End.

In the communication system of the present invention, two users can each use their communication device to make a call. During the call, two users can be the Talker or the Receiver in sequence. For convenience of explanation, the communication device held by the Talker user is referred to as the Talker device, and the communication device held by the recipient user is referred to as the terminating device. As mentioned above, the identity of the originating device and the terminating device may be constantly switched during the call, so the steps of the present invention are not limited to being performed by a particular communication device.

In step 110, the two users can individually set up the communication device they are holding. For example, the calling device can provide a user interface for the Talker user to record a voice of their own voice as the first reference signal, and set the value of the first threshold and the first adjustment parameter; The device can provide a user interface for the user of the receiving party to record a voice of their own as a second reference signal and set the values of the second threshold and the second adjustment parameter. The first threshold and the second threshold may be used as a determination as to whether the volume needs to be adjusted, and the first adjustment parameter and the second adjustment parameter may be adjustment amounts each time the volume adjustment is performed. Figure 2 is a schematic diagram of the present invention when the step 110 is performed, showing the user interface provided by the terminating device or the terminating device. It should be noted that other various forms of user interface are within the scope of the present invention.

In step 120, the source device can perform the function of voice recognition. The calling device analyzes the received audio signal according to the first reference signal (such as the voice of the calling user) set in step 110 to identify the first voice signal and the first background signal. The first voice signal is related to the content of the call of the Talker user, and the first background signal is related to the background noise of the environment in which the Talker user is located.

In step 130, the originating device can determine whether the volume needs to be adjusted. If the environment of the utterer user is quite noisy, the volume of the first voice signal is lower than the volume of the first background signal exceeds the first threshold, and the utterer device performs step 140 to automatically follow the first adjustment parameter. The volume of the first voice signal is increased, and then step 150 is performed to send the volume-adjusted audio signal to the receiving device. If the environment of the utterer user is quite quiet, the volume of the first voice signal is not lower than the volume of the first background signal exceeds the first threshold, and the utterer device directly performs step 150 to send the original audio signal. To the receiving device.

In step 160, the originating device can detect the second background signal during the call, wherein the second background signal is related to the background noise of the environment in which the receiving party user is located.

In step 170, the receiving device can determine whether the volume needs to be adjusted. If the environment of the user of the receiving party is quite noisy, the volume of the audio signal is lower than the volume of the second background signal exceeds the second threshold, and the receiving device performs step 180 to automatically follow the second adjustment parameter. Increase the volume of the audio signal. If the environment of the receiving party user is quite quiet, the volume of the audio signal is not lower than the volume of the second background signal exceeds the second threshold, and the calling device does not adjust the volume.

In the present invention, the calling device performs voice recognition and automatically adjusts the volume of the conversation user's conversation content according to the environment; the receiving device automatically adjusts the audio received from the source device according to the environment. Signal. Therefore, in different environments, the mobile communication method of the present invention can increase the recognition of the communication content, and the user of the calling party and the user of the receiving party do not need to manually adjust the volume of the loudspeaker, so that the voice of the other party can be clearly heard.

The above are only the preferred embodiments of the present invention, and all changes and modifications made to the scope of the present invention should be within the scope of the present invention.
