What is LMNT?

LMNT is a text‑to‑speech API that delivers fast, lifelike audio with low latency (150‑200 ms) suitable for conversational applications, virtual agents, and interactive games. It supports unlimited studio‑quality voice cloning from a brief 5‑second recording and offers 24 language options, including the ability to switch languages mid‑sentence.

The service provides real‑time streaming without concurrency or rate limits, allowing continuous speech generation for live interactions. Developers can integrate LMNT via a straightforward REST API, with example code available in the official documentation, and can test functionality in an online playground.
