Problems solved by technology

However, sometimes users want to keep the recording process and don’t want to miss the incoming call, that is, they hope that the call and recording can be carried out at the same time without interfering with each other. However, the existing communication terminals cannot meet the above needs of users, thus affecting the user experience.

[0045] see figure 1 , propose the first embodiment of the method of simultaneous conversation and recording of the present invention, said method comprises the following steps:

[0046] Step S101: Collecting sound signals during the call and recording

[0047] The communication terminal is talking and recording at the same time, and the calling event and recording event are events of the same priority. The communication terminal can first start the recording, and during the recording process, it suddenly receives an incoming call, and after the call is established, the recording is transferred to the background to continue; or it can first establish the call, and start the recording during the call. In short, the two are carried out simultaneously without interfering with each other.

[0048] The sound signal collected by the sound collection unit such as a microphone includes a call signal and a recording signal, wherein the call signal is the sound from the user, and the r...

[0056] see figure 2 , propose the second embodiment of the method of simultaneous conversation and recording of the present invention, said method includes the following steps:

[0057] Step S201: Collecting sound signals during calls and recordings

[0058] Step S202: Comparing the volume difference of the sound signals collected by the two sound collection units

[0059] Step S203: Separate the sound signal whose volume difference is smaller than the preset value as the recording signal

[0060] The present invention is especially applicable to the situation where the recording sound source is two meters away from the communication terminal. The volume difference of the sound emitted by the two meters away from the sound source collected by the two sound collection units is usually less than 6 decibels, so the volume difference is directly reduced to less than 6 decibels The sound signal is separated and used as a recording signal.

[0064] see image 3 , propose the third embodiment of the method of simultaneous conversation and recording of the present invention, the method includes the following steps:

[0065] Step S301: Collecting sound signals during the call and recording

[0066] Step S302: Comparing the volume difference of the sound signals collected by the two sound collection units

[0067] Step S303: Separate the sound signal whose volume difference is smaller than the preset value as the recording signal

[0068] Step S304: Separate the sound signal whose volume difference is greater than or equal to the preset value as a call signal

[0069] In this embodiment, the recording signal and the call signal are separated directly by comparing the volume difference of the sound signals collected by the two sound collection units. Wherein, the preset values ​​described in steps S303 and S304 may be the same or different, preferably both are 6 decibels.

Abstract

The invention discloses a method for achieving telephone conversation and sound recording simultaneously and a communication terminal. The method comprises the steps that in the telephone conversation and the sound recording process, sound signals are collected; sound recorded signals are separated from the sound signals; the sound recorded signals are transmitted to a sound recording unit. In this way, sounds generated by users in the telephone conversation process are filtered away from the sound signals, the pure sound recorded signals are obtained, the recorded sounds have no telephone conversation content of the users, interferences caused by telephone conversation with sound recording are avoided, and the requirement of the users for achieving telephone conversation and sound recording simultaneously is met. When the users are on a call in the sound recording process, sound recording is shifted into the background to proceed; or in the telephone conversation process, sound recording can be started, so that telephone conversation and sound recording can be conducted simultaneously, and user experience is improved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and a communication terminal for talking and recording at the same time. Background technique [0002] In the prior art, when the communication terminal is recording, if a call comes in suddenly, when the call is connected and the call is made, because the prior art cannot perform multiplexing of the microphone, the communication terminal will suspend the current recording and save it, and then switch to the call path to continue. call. If the user wants to record uninterrupted, there is no other way but to use airplane mode to not receive incoming calls. However, sometimes users want to keep the recording process and don’t want to miss incoming calls, that is, they hope that the call and recording can be performed simultaneously without interfering with each other. However, the existing communication terminals cannot meet the above needs of users, thus affecting ...
