## What we know about LMNT

LMNT sits in the text-to-speech apis category, where it is speed-and-affordability challenger: a single fast model (Blizzard 2) with streaming-first APIs, unlimited voice clones on every tier, and flat subscription pricing with per-1K overage. We keep this LMNT profile grounded in primary sources, each fact dated to when we last confirmed it.

On pricing, LMNT starts at $10 per month for its entry tier. That is the sticker rate: real production cost usually runs higher once you add a language model, a voice provider, and telephony minutes.

On capabilities, LMNT covers streaming audio output, realtime websocket api, instant voice cloning, emotion / style controls, and word-level timestamps. Each of those is verified against LMNT's own docs or dashboard, not marketing copy.

Placed against the 46 text-to-speech tools we track, LMNT's strongest showing is the 15th-widest language coverage, while it trails at 9th on latency - a spread worth weighing against your own priorities.

In total we track 17 verified facts for LMNT today, each linking the primary source it came from so you can check our work - and vendor claims we have not measured ourselves are labeled as such on the LMNT fact sheet below.
