3.2.1
Some Explanations about full- half-duplex Introduction
traditional telephone connection which uses handsets both sides there always full-duplex conversation. Because gains required microphone earpiece moderate, extra work done prevent acoustical feedbacks (echoes). soon people start enjoy hands-free telephony whether office signal levels loudspeaker microphone become greater. there would circuitry prevent acoustical feedback, calling partner far-end telephone would hear himself very loudly, especially phone conversation takes place mobile phone, speech delayed echoes extremely disturb person calling.
3.2.2
Considerations prevent echoes
past when DSPs were expensive, slow weak performance, only possibility prevent echo unused signal connections. This means signal transmission permitted only direction. Either from handset phone speakerphone, other round, both transmission paths same time. this document this method called half-duplex. circuitry phone algorithm decide, which person caller which receiver, corresponding path switched transmission. other path gets attenuation about prevent echo. This algorithm also called Stronger-Wins-Algorithm because double talk situation person with stronger voice will transmission path other understood. case half-duplex conversation both persons have very disciplined other finish speaking avoid misunderstandings because cutting words. Nowadays' performance much more powerful, sophisticated algorithms process speech signals. Therefore possible simulate acoustical behavior room where hands-free phone used digital Filter subtract simulated signal from microphone signal. better image room acoustics, better echo cancellation. performance Echo Canceller benchmarked rate, algorithm needs adapt Echo-Cancel-Filter room acoustics. faster adaptation, better echo cancellation, acoustics continuously changes: driver turning steering wheel, gear shift lever used, because strong break passengers move around, etc. these situations Echo Canceller adapt room acoustics. Echo-Filter well adapted, echo, which heard telephone reduced minimum. Otherwise strong echo heard. prevent this, combination Echo Canceller Stronger-Wins-Method available ACE.

Detailed Description Car-Phone Demo provides which useful give far-end input defined level. view signals, signal value high possible advantageous avoid signal overload compare level adjusted very good method comfortably adjust volume car. Because people speak with different strength, person adjust signal level will need care about different speakers.
Noise Reduction
speakerphone module supports Noise Reduction block receive path which reduces sound regular signal power. Signal power speech usually rather irregular will filtered. parameter provided adjust maximal amount noise reduction. speech distorted much, parameter been adjusted high. Values from give best performance Noise Reduction unit. background noise reduced minimum distortion speech signal negotiable.
Comfort Noise Noise Adaptation
comfort noise algorithm makes conversation more easy far-end caller. Think situation, echo canceller fully adapted because driver turning. echo suppression gives some attenuation prevent echoes. this case, far-end caller will recognize attenuation because noise getting softer. cover this, artificial noise injected transmit signal. result this, attenuation only heard speaker's voice background noise. After short time, echo canceller fully readapted echo suppressor needed. Though comfort noise only needed very short periods time, improves performance car-phone. Noise Adaptation shows it's effect inside car. With this, four parameters adapted depending noise level car. There important parameters: loudspeaker gain total attenuation. loudspeaker gain incremented noise level rises. This makes manual volume control unnecessary. prevent distortion loudspeaker, volume increase limited. total attenuation reduced noise level rises echo masked noise. With this, side effect eliminated. noisy environment, echo canceller needs little more time fully adapt. echo cancel requirement decreased, adaptation time full-duplex also decreased.
