OpenAI says it can clone a voice from just 15 seconds of audio

OpenAI just announced that it recently conducted a small-scale preview of a new tool called Voice Engine. This is a voice cloning technology that can mimic any speaker by analyzing a 15-second audio sample. The company says it generates "natural-sounding speech" with "emotive and realistic voices." The technology is based on the company's pre-existing text-to-speech API and it has been in the works since 2022. OpenAI has already been using a version of the toolset to power the preset voices available in the current text-to-speech API and the Read Aloud feature. There are a bunch of samples on the company's official blog and they sound eerily close to the real thing.
