Guidelines for building responsible synthetic voices

Learn about responsible deployment

Synthetic voices must be designed to earn the trust of others. Learn the principles of building synthesized voices that create confidence in your company and services.

Obtain consent from voice talent

Help voice talent understand how neural text-to-speech (TTS) works and get information on recommended use cases.

Be transparent

Transparency is foundational to responsible use of computer voice generators and synthetic voices. Help ensure that users understand when they’re hearing a synthetic voice and that voice talent is aware of how their voice will be used. Learn more with our disclosure design guidelines.
