A new Gradium Text-to-Speech model is live and is now the default. Existing voices, including custom voices, work as-is. The model reads the structured entities that break voice agents in production, such as phone numbers, email addresses, IBANs and reference codes, with no pre-processing or text normalization needed.
Speech-to-Text requests now require a language in json_config . Our ASR gives its best results when the language is known, so set it whenever you can: en , fr , es , pt , or de . When the language is not known ahead of time, pass any and the model detects it from the audio. Requests that already set a language or any are unaffected.
We're excited to announce major updates to the Gradium API and Gradium Studio, delivering enhanced text-to-speech (TTS) and speech-to-text (STT) capabilities for developers and enterprises.
- Model selector in Gradium Studio : the Text-to-Speech page now has a Model dropdown to switch between the production model and gradium-tts-beta , showing each model_name with a copy button. Shareable studio links : pre-configure a session with ?voice= , ?model_name= , ?text= and ?language= and share the full setup as a single link.
Our live translation models ( stt-translate for translated transcription and s2s-translate for Speech-to-Speech) now produce more natural, more accurate translations, with better context understanding across a conversation. The quality gains are most noticeable on conversational speech. See Speech-to-Speech and the Speech-to-Text overview to get started.
