What it is
Pulse is Smallest AI's speech-to-text API, built for developers adding live transcription, voice agents, or call analytics into their own products. It streams over WebSocket at sub-100ms latency with speaker diarization, keyword boosting, and built-in PII/PCI redaction, and covers 21 languages live, 26 in batch. A companion model, Pulse Pro, trades multilingual support for English-only accuracy that ties for #2 on the public Open ASR Leaderboard.
