To ward off potential legal headaches, Microsoft’s requiring that users give “explicit consent” in the form of a recorded statement before a customer can use personal voice to synthesize their voices.
Access to the feature is gated behind a registration form for the time being, and customers must agree to use personal voice only in applications “where the voice does not read user-generated or open-ended content.”
“Voice model usage must remain within an application and output must not be publishable or shareable from the application,” Microsoft writes in a blog post.
