Unreal Speech

Cut text-to-speech costs. Production-ready. Stream in 300ms. Generate 10-hr audio. 48 voices & 8 languages. Per-word timestamps. 250K chars free

Unreal Speech gives developers a text-to-speech API built to cut the cost of turning text into audio, positioned as substantially cheaper than competitors like Eleven Labs. It's aimed at production apps that need speech, offering audio streaming that starts within 300 milliseconds and support for requests up to ten hours of audio in a single call.

The API includes 48 voices across 8 languages and returns per-word timestamps, so developers can highlight words in sync with the audio as it plays, useful for things like karaoke-style captions or accessibility features. A live demo on the site lets you type text and hear it synthesized through the Kokoro-82M model, with controls for voice, language, format, speed, and pitch. The service also supports streaming both audio and timestamps together over a websocket connection, and it's categorized here alongside other research and text-to-speech tools.

New users get a set number of free characters to try the API, and the site describes a model where usage becomes cheaper as it scales, alongside paid options beyond that free allowance. Developers building podcasts, videos, or voice-driven apps can grab a free API key to test the voices and timestamp accuracy on their own text.
