Speech-to-Text (ASR)

In depth

Automatic speech recognition, the task of converting spoken audio into written text. Modern ASR models are trained end to end on large amounts of paired audio and transcripts. OpenAI's Whisper, trained on 680,000 hours of multilingual audio, showed that this kind of weak supervision transfers zero-shot to standard benchmarks without fine-tuning. ASR is the first stage of most voice agents, dictation tools, and meeting transcription pipelines.
