| BackgroundDetect( )
|
Plays a file in the background and detects
talking
|
BackgroundDetect(filename[,sil[,min[,max]]])
Similar to Background( ), but attempts
to detect talking.
During the playback of the file, audio is
monitored in the receive direction. If a period of non-silence that
is greater than min milliseconds yet less than
max milliseconds and is followed by silence for at
least sil milliseconds occurs, the audio playback
is aborted and processing jumps to the talk extension, if
available.
If unspecified, sil,
min, and max default to 1,000 ms,
100 ms, and infinity, respectively.
Returns -1 on hangup, and 0 on
successful playback completion with no exit conditions.
