Customers can choose either a prebuilt or a custom neural voice for their avatar. If the same person's voice and likeness are used for both the custom neural voice and the custom text to speech avatar, the avatar will closely resemble that person.
As part of Microsoft's commitment to responsible AI, text to speech avatar is designed with the intention of protecting the rights of individuals and society, fostering transparent human-computer interaction, and counteracting the proliferation of harmful deepfakes and misleading content, the company said.
Customers can upload their own video recording of avatar talent, which the feature uses to train a synthetic video of the custom avatar speaking, the blog post reads.
