What is CereProc?

CereProc is an Edinburgh speech technology company that has been building text-to-speech voices since the mid 2000s, known for character and regional accents rather than flat narration. The CereVoice engine runs as an SDK on desktop and mobile, as a server for concurrent streams, and as a cloud API billed per character, and its voices are used for game characters, announcements, education and assistive communication. Custom voice work covers a service for building a copy of your own voice and studio projects such as reconstructing a voice for someone losing theirs. Much of the business is licensing, so talks start with a quote.

FAQ

What makes CereProc different?

Accent and character. The voice library covers regional variants and emotional delivery that large generic providers often skip, which is why games and accessibility projects use it for characters rather than neutral narration.

Can I create a voice of my own?

Yes, the CereVoiceMe service builds a personal voice from recordings made at home, and the company also works on voice reconstruction for people losing their speech to illness, using recorded material and adaptive techniques.

Is there a free trial?

There is a cloud signup with a limited monthly allowance for developers, and academic use of the SDK is free. Commercial deployments are licensed, usually after a discussion about volume and target platform.
