本发明实施例在开始发送音频数据之后，音频数据发送完成之前即对音频接收单元进行初始化，移动终端无需等待数据发送完毕之后再开启录音模块，并且通过标志位识别该音频数据来自发送端还是接收端，从而节省了录音单元初始化的时间，以达到缩短交互时间，提高音频数据交互速度的目的。In the embodiment of the present invention, the audio receiving unit is initialized after the audio data is sent and before the audio data is sent, and the mobile terminal does not need to wait for the data to be sent before turning on the recording module, and identifies whether the audio data comes from the sending end or the receiving end through the flag bit. end, thereby saving the time of recording unit initialization, so as to shorten the interaction time and improve the audio data interaction speed.
以上仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。The above are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention. Inside.
