Pulse, built by Smallest AI, is a speech-to-text API purpose-built for real-time voice applications: live call transcription, voice agents, and captioning, alongside a high-throughput batch mode for recorded audio. It streams over WebSocket with sub-100ms time-to-first-token at low concurrency, and includes speaker diarization, word- and sentence-level timestamps, keyword boosting for domain vocabulary, voice-activity events, and inverse text normalization out of the box.
A companion model, Pulse Pro, trades multilingual support for English-only batch transcription tied for #2 on the public Open ASR Leaderboard, built for high-volume call center, meeting, and financial-audio transcription at scale.
Both models include built-in PII and PCI redaction (currently English and Hindi), and the platform holds ISO 27001, SOC 2 Type II, HIPAA, and GDPR compliance, with on-premise deployment available on Enterprise plans.
