About Voice Engine by OpenAI

Voice Engine is a model developed by OpenAI that generates natural-sounding, emotive synthetic speech from a text input and a single 15-second audio sample of a speaker. First developed in late 2022, it has been used to power preset voices in OpenAI's text-to-speech API, ChatGPT Voice, and Read Aloud. OpenAI has conducted small-scale previews with trusted partners to explore applications such as reading assistance for children and non-readers, video and podcast translation while preserving the original speaker's accent, remote healthcare worker training in local languages, and augmentative communication for non-verbal individuals. The company is proceeding cautiously due to the potential for misuse of synthetic voices and is engaging in dialogue about responsible deployment.
