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

Mar 30, 2024 - engadget.com
OpenAI has previewed a new tool, Voice Engine, a voice cloning technology that can mimic any speaker using a 15-second audio sample. The technology, which has been in development since 2022, generates "natural-sounding speech" with "emotive and realistic voices" and is based on the company's pre-existing text-to-speech API. OpenAI sees potential applications in reading assistance, language translation, and aiding those with speech conditions. However, the company acknowledges the technology's potential for misuse, such as deepfake creation, and is working to address privacy concerns before a full rollout.

The company has implemented safety measures, including watermarking to trace the origin of any audio and proactive monitoring of system usage. When the product officially launches, there will be a "no-go voice list" to prevent AI-generated voices too similar to prominent figures. Pricing data suggests Voice Engine could cost $15 per one million characters, significantly undercutting competitors. OpenAI has also announced a partnership with Microsoft to build a $100 billion AI-based supercomputer called "Stargate".

Key takeaways:

  • OpenAI has previewed a new tool called Voice Engine, a voice cloning technology that can mimic any speaker by analyzing a 15-second audio sample.
  • The technology is expected to be useful for reading assistance, language translation, and helping those with speech conditions, but there are concerns about potential misuse for deepfake creation.
  • OpenAI is incorporating feedback from various sectors and has implemented safety measures like watermarking and proactive monitoring to minimize risks.
  • The company has not yet announced a rollout date, but pricing data suggests Voice Engine could cost $15 per one million characters, potentially undercutting competitors like ElevenLabs.
