Gradium Launches Voice Design: Custom Voices from a Single Prompt

Voice AI company Gradium has released Voice Design: users simply write a prompt describing the desired accent, age, gender, and speaking pace, and a ready-to-use new voice is generated within seconds. The feature is now live in the Gradium API and Studio, and is available for free. The company says the underlying model was originally built to internally screen customer voices and is now officially open to everyone.

Confirmed

• Voice Design supports generating custom voices via prompts describing accent, age, gender, speaking pace, and other dimensions, with results in seconds.
• The feature is live on the Gradium API and Studio, free of charge.
• Users have already tested it: sharer amritwt actually generated a custom voice; other users tried specific voices such as a "contemporary Singaporean English accent, crisp and practical, male in his 20s," and ThePeterMick also generated a voiceover voice, showing the feature works out of the box for ordinary users.

Why it matters

• Voice customization previously relied on recording-based cloning or professional tuning; Voice Design lowers the barrier to writing a single natural-language description, dramatically cutting personalization costs for voiceover, audio content, and in-app speech scenarios.
• Free availability means developers can integrate it into APIs at low cost, potentially intensifying competition in the speech synthesis space.
