What does “Speech-to-text” mean?
Speech-to-text: Turning spoken audio into written text. Systems are trained on recordings paired with transcripts, and current models handle accents, background noise and many languages far better than older ones; some also identify who is speaking or add timestamps. Errors still occur with rare names, jargon and overlapping voices.
