Company Overview

Lmnt (pronounced "element") is a San Francisco-based speech synthesis company that provides an ultra-low-latency text-to-speech API designed specifically for real-time voice AI applications including conversational AI agents, voice interfaces, and interactive voice response systems. While traditional TTS APIs have latency measured in hundreds of milliseconds, Lmnt's streaming architecture delivers the first audio bytes in under 100 milliseconds, enabling natural back-and-forth voice conversations without perceivable delay. The company offers voice cloning from short samples and a library of pre-built voices with emotional range, all accessible through a developer-friendly API. Lmnt is used by companies building AI companions, customer service voice bots, and voice-enabled productivity tools that require speech synthesis fast enough to feel natural. Founded in 2021 by ex-Google Brain researchers, Lmnt raised seed funding to commercialize research on real-time speech synthesis. It competes with ElevenLabs Turbo, Cartesia, and Deepgram TTS in the low-latency speech API market.
