Multimodal AI
Voice activity detection
Detecting which parts of a recording contain someone speaking.
Example
A speech tool skips long silences before turning speech into writing.
Why people use it
It helps audio tools focus on speech instead of processing long stretches of silence.
What you'll hear
“Start processing when someone begins speaking.”
What this means for you
Try quiet voices and noisy rooms to check that speech is not cut off.
Can you control it?

Common questions
- Does voice activity detection identify the words being spoken?
- No. It detects speech presence rather than transcribing content.
- Can it mistake background sound for speech?
- Yes. Music, noise or other sounds can trigger an incorrect detection.
- Can it cut off a quiet speaker?
- Yes. Faint speech may be mistaken for silence or background noise.
