BackgroundDetect() — Plays a file in the background and detects talking
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.
