The Speech Processing algorithms comprise of signal processing algorithms that perform

different functions on speech signals. The Noise Suppression algorithm reduces the

background noise. The Acoustic Echo Cancellation reduces the echo due to the acoustic

coupling between a speaker and microphone. Line Echo cancellation reduces the echo from

impedance mismatch in telecommunication networks. The Speech Recognition library

provides a speaker independent speech recognition system which can be used to implement

a speech based command interface.
