Together they replace the usual three-model cascade (Speech-To-Text, Text-To-Text translation, Text-To-Speech) and deliver the combination of highest accuracy and lowest latency, with the ability to choose the target voice for the generated speech, including a clone of your own. This post covers what stt-translate does, how we measure its quality, how s2s-translate pairs it with our TTS models for a full Speech-To-Speech workflow, and how both compare with gpt-realtime-translate and gemini-3.5-live-translate .
