### AI overview

Gradium announces stt-translate, which converts speech directly into translated text, and s2s-translate, which returns translated speech through a WebSocket. The models support five languages, and s2s-translate lets users choose a catalog voice or a clone. The post compares translation quality and latency with two competing services using BLEU and MetricX benchmarks.

### Source excerpt

Gradium launches stt-translate and s2s-translate: real-time Speech-To-Text and Speech-To-Speech translation across English, French, German, Spanish, and Portuguese, with a better accuracy-latency tradeoff than gpt-realtime-translate and gemini-3.5-live-translate and full control of the output voice, including cloning.
