Segmentation
Detect and isolate speech and other sounds
Detect speech and other sounds and locate their start and end times.
For streaming applications, use a voice activity detector (VAD) to
output the probability that speech is present in a given frame. You can
also use speech2text
to create time-aligned word labels for
speech signals.
