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.
