Bob 2.0 implementation of Voice Activity Detection (VAD) based on 4Hz energy filtering

This algorithm is a legacy one. The API has changed since its implementation. New versions and forks will need to be updated.
This algorithm is splittable

Algorithms have at least one input and one output. All algorithm endpoints are organized in groups. Groups are used by the platform to indicate which inputs and outputs are synchronized together. The first group is automatically synchronized with the channel defined by the block in which the algorithm is deployed.

Group: main

Endpoint Name Data Format Nature
speech system/array_1d_floats/1 Input
labels system/array_1d_integers/1 Output

Parameters allow users to change the configuration of an algorithm when scheduling an experiment

Name Description Type Default Range/Choices
rate Sampling rate of the speech signal float64 16000.0 [2000.0, 256000.0]
win_length_ms The length of the sliding processing window, typically about 20 ms float64 20.0
win_shift_ms The length of the overlap between neighboring windows. Typically the half of window length. float64 10.0
