Bases: Mapping

Reader class for ‘vad.scp’.

Different from segments, the vad.scp would focus on utterance-level, while the segments are expected to focus on a whole session. The major usage in ESPnet is to guide the silence trim for UASR.

Examples

key1 0:1.2000 key2 3.0000:4.5000 7.0000:9:0000 …

>>> reader = VADScpReader('wav.scp')
