Patent ID: 8423357

Claim:
A communication device for generating enhanced audio signals, the communication device comprising: at least one microphone configured to acquire an audio signal, wherein the audio signal comprises at least one speech signal and at least one noise signal; and a noise processor configured to: detect a pitch estimation of the audio signal; initialize a plurality of processing parameters for the audio signal; and process the audio signal based on the pitch estimation and the processing parameters, wherein the audio signal is processed to reduce the at least one noise signal and generate an enhanced audio signal; wherein the noise processor is further configured to: decrease the pitch estimation value based on a fundamental frequency of the audio signal based on a first predefined condition; increase the pitch estimation value based on a fundamental frequency of the audio signal and based on a second predefined condition; and multiply the pitch estimation value with at least one of the plurality of processing parameters to generate an enhanced audio signal; a transmitter for transmitting the enhanced audio signal over a communication channel; a switch configured to: enable the noise processor used for processing the audio signal to reduce at least on noise signal, and disable the noise processor used for processing the audio signal to reduce noise signal.
