Speech Enhancement


Single-microphone solution
of speech enhancement can be used for reduction of external hindrances and broadband color noises in speech signal. Controlled level of noises suppression in speech is up to 60 dB. ...

Multi-microphone solution

of speech enhancement can be effectively used when noise from many different sources needs to be canceled. In its simplest form the technique uses two microphone solution. Speaker is recorded synchronous with the source of hindrance (noise). The first microphone bases near by speaker, but the second one bases near by source of hindrance or noise. ...

Microphone Array solution

of speech enhancement can be used for reduction of external hindrances and ambient noises in speech source signal. In its simplest form the technique uses two array microphone configurations. By using acoustical beam-forming techniques, the microphone array can "focus" on the speaker's position. ...
