Voice Activity Detector (VAD)
is used for detection silence intervals. Principle of functioning of
detector is based on methods of adaptive filtrations, allowing tracing
dynamically appearance of fragments of noise signal. Depending on
conditions of the channel, mips and quality detection, it’s possible
different realizations of variants Voice Activity detectors. It allows
using them effectively on the background of broadband noises and
channel distortion. ...
Phone Talk Detector (PhTD)
is used for detection of speech intervals. Such detector can be used
in devices, where it is important to detect exactly fragments of
speech signal. For instance, in telephone systems, when it is
necessary to detect moment of the beginning of talk between speakers
on telephone line and its duration. ...
Double Talk Detector (DTD)
can be used for estimate degree of similarity between channels. Double
Talk Detector effectively can be used at the suppression of echo in
devices VOIP telephony (with echo cancellers). It's developed two
modification of Double Talk detectors. ...
Acoustic Clipping Detector (ACD)
is used for estimation degree of clipping signal, appearing because of
the excess of maximum amplitude level of signal. The
restrictions of the maximum level of signal amplitude can be added by
mike or channel itself or both of them simultaneously.
Acoustic Clipping Detector can be effectively used in devices IP
telephony, Call service centers, where it’s necessary constantly
monitoring of the incoming clipping signal (acoustic shocks). ...
