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.
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. ...
