ABSTRACT:
A method for audio modulation is provided. The method including: obtaining the digital audio signals of the caller in the process of communications; analyzing the digital audio signals and obtain a voice frequency of the caller; reading a voice frequency of the user from a memory, and calculate the rate of the voice frequencies between the caller and the user; modulating the user' analog audio signals according to the rate of the voice frequencies; converting the modulated analog audio signals into digital audio signals; coding the digital audio signals and modulating the coded digital audio signals and transmitting the modulated digital audio signals to the caller. Through the method, the user's voice is modulated to sound like the caller's voice, thereby increasing the interest of the process of communicating.
