The

activation_threshold

parameter is a configurable option in the Silero Voice Activity Detection (VAD) system. It determines the threshold for considering a frame as speech, allowing you to adjust the sensitivity of speech detection. You can set this parameter in two ways: • When initially loading the VAD model using the

load()

method (default value is 0.5). • By updating options after creation using the

update_options()

method on either the VAD object or a VADStream. The parameter accepts float values. A higher threshold requires stronger speech signals to be detected as speech, while a lower threshold makes the system more sensitive to detecting speech. Sources: livekit.plugins.silero API documentation
