Voice synthesis has come a great distance since 1978’s Communicate & Spell toy, which as soon as wowed individuals with its state-of-the-art capability to learn phrases aloud utilizing an digital voice. Now, utilizing deep-learning AI fashions, software program can create not solely realistic-sounding voices, but in addition convincingly imitate current voices utilizing small samples of audio.
Alongside these strains, OpenAI simply introduced Voice Engine, a text-to-speech AI mannequin for creating artificial voices primarily based on a 15-second phase of recorded audio. It has supplied audio samples of the Voice Engine in motion on its web site.
As soon as a voice is cloned, a person can enter textual content into the Voice Engine and get an AI-generated voice consequence. However OpenAI shouldn’t be able to broadly launch its expertise but. The corporate initially deliberate to launch a pilot program for builders to enroll in the Voice Engine API earlier this month. However after extra consideration about moral implications, the corporate determined to reduce its ambitions for now.
“Consistent with our strategy to AI security and our voluntary commitments, we’re selecting to preview however not broadly launch this expertise presently,” the corporate writes. “We hope this preview of Voice Engine each underscores its potential and in addition motivates the necessity to bolster societal resilience in opposition to the challenges introduced by ever extra convincing generative fashions.”

Voice cloning tech usually shouldn’t be significantly new—we have coated a number of AI voice synthesis fashions since 2022, and the tech is energetic within the open supply group with packages like OpenVoice and XTTSv2. However the concept that OpenAI is inching towards letting anybody use their specific model of voice tech is notable. And in some methods, the corporate’s reticence to launch it absolutely may be the larger story.
OpenAI says that advantages of its voice expertise embody offering studying help by way of natural-sounding voices, enabling world attain for creators by translating content material whereas preserving native accents, supporting non-verbal people with personalised speech choices, and aiding sufferers in recovering their very own voice after speech-impairing situations.
Nevertheless it additionally implies that anybody with 15 seconds of somebody’s recorded voice might successfully clone it, and that has apparent implications for potential misuse. Even when OpenAI by no means broadly releases its Voice Engine, the power to clone voices has already precipitated bother in society by way of telephone scams the place somebody imitates a beloved one’s voice and election marketing campaign robocalls that includes cloned voices from politicians like Joe Biden.
Additionally, researchers and reporters have proven that voice-cloning expertise can be utilized to interrupt into financial institution accounts that use voice authentication (corresponding to Chase’s Voice ID), which prompted Sen. Sherrod Brown (D-Ohio), the chairman of the US Senate Committee on Banking, Housing, and City Affairs, to ship a letter to the CEOs of a number of main banks in Could 2023 to inquire concerning the safety measures banks are taking to counteract AI-powered dangers.
