Technology that detects segments of an audio recording where actual speech occurs. Helps remove silence, split audio into segments, and reduce transcription cost and time.
Why it matters
Filters out silence before transcription — you pay for and wait only for the parts where someone is speaking, and recordings are split at natural breaks.
What's missing without it
Without voice detection, transcription processes the entire recording including silence and noise — longer, more expensive, and with poorer segmentation of speech.
When it is used
Before transcribing recordings, in voice assistants, and when editing long audio materials.
How we use it
Before STT, the system cuts out long silences from the recording and sends only speech segments.
