Gradium Launches stt-translate and s2s-translate, Real-Time Speech Translation Models Beating gpt-realtime-translate on Accuracy and Latency

Gradium has launched two real-time speech translation models, stt-translate and s2s-translate, which provide translation across 20 language pairs including English, French, German, Spanish, and Portuguese. These models streamline the traditional three-model setup into a two-model architecture, combining transcription and translation in a single pass with a text-to-speech (TTS) stage, achieving superior accuracy and lower latency compared to gpt-realtime-translate and gemini-3.5-live-translate. This advancement is significant for practitioners as it enhances real-time translation capabilities while offering features like output voice selection and cloning, potentially improving user experience in multilingual applications.
