SAN FRANCISCO – OpenAI is sharing early results from a test for a feature that can read words aloud in a convincing human voice – highlighting a new frontier for artificial intelligence and raising the spectre of deepfake risks.

The company is sharing early demos and use cases from a small-scale preview of the text-to-speech model, called Voice Engine, which it has shared with about 10 developers so far, a spokesperson said. OpenAI decided against a wider rollout of the feature, which it briefed reporters on earlier this month.
