Pulse — Speech-to-Text by Smallest AI

Pulse is a voice AI platform that brings together everything you need to work with speech: speech-to-text, text-to-speech, speech-to-speech, voice cloning, and real-time voice agent technologies, all in one place.

At its core, Pulse offers powerful speech-to-text models that deliver accurate transcription across 38+ languages, handling global accents and dialects with impressive ease. Latency can go as low as 64 milliseconds, so conversations feel natural instead of delayed.

Beyond transcription, the platform supports speaker diarization, sentiment and emotion recognition, and language identification, giving you deeper insight into every conversation. For building voice assistants, Pulse provides voice agent orchestration, telephony support, knowledge bases, and enterprise deployment options, making it suitable for teams of any scale.
