OpenAI updated its Service Terms to add a new subsection on Prompt-to-Voice, a feature that generates synthetic speech from text. The updated terms require users to obtain express consent before reproducing any person's voice, clearly disclose that generated speech is AI-generated, and not remove or alter OpenAI-provided AI-origin indicators. Critically, OpenAI's indemnification obligations do not extend to Prompt-to-Voice or its output, meaning customers bear the legal risk if generated speech infringes third-party rights or violates consent requirements.
Developers: You cannot generate synthetic speech that sounds like a real person without their explicit permission.
Developers: You must tell users that the voice they hear is artificial and cannot hide or modify OpenAI's AI markers.
Developers: If someone sues because generated speech infringes their rights or violates consent, OpenAI will not defend or pay for your legal costs.
The updated terms introduce a new Prompt-to-Voice feature with strict usage requirements. Users must obtain express consent before reproducing any person's voice, must clearly disclose that generated speech is AI-generated, and must not remove or alter OpenAI-provided AI-origin indicators. Critically, OpenAI's indemnification obligations do not apply to Prompt-to-Voice or its output, meaning customers and End Users bear full legal liability if generated speech infringes third-party intellectual property rights or violates consent requirements.
→ Review your current use of Prompt-to-Voice to identify whether you are reproducing any person's voice without documented express consent.
→ Implement consent collection and disclosure mechanisms in any application or service that uses Prompt-to-Voice.
→ Audit your privacy notices and terms of service to disclose Prompt-to-Voice use and AI-generated speech to end users.
