Our new Text-to-Speech model is now the default, with more expressive speech and lower latency. Existing requests using default use the new model without a setup change. gradium-tts-beta also routes to this model until the next TTS beta arrives. Keep that alias to follow future betas, or use default to stay on stable releases.
Clean up a voice you already have without changing its language or who is speaking. POST /voice-generator/enhance takes a flagship voice, a clone or a candidate and returns candidates with background noise reduced. Audition and convert them like Voice Design candidates. Voice Enhance is in beta; output quality will keep improving.
Our new Text-to-Speech model is available in public beta, with lower latency and more expressive speech. In our latest measurements, the beta reaches time to first audio in under 50 ms, against 225 ms for the production model. Latency varies with network conditions and input. Set model_name to "gradium-tts-beta" in your TTS setup to use the beta.
Gradium has achieved ISO 27001 certification, independently audited by A-LIGN. Visit our Trust Center for certification details and security documentation .
Studio has a redesigned voice catalogue, new voice search controls in Text-to-Speech, and more ways to preview voices in Voice Design. Voice catalogue: Customize layout between tile or list views, group voices by language, and choose which properties to display.
Create a voice from a written description, no audio sample needed. Describe the accent, age and character you need, generate up to five candidates, and keep your favourite. The voice works with the same Text-to-Speech endpoint as any catalogue voice. In our blind listening evaluation, native speakers judged how well voices matched accent prompts.
