Voice synthesis has come a great distance since 1978’s Speak & Spell toy, which as soon as wowed folks with its state-of-the-art capacity to learn phrases aloud utilizing an digital voice. Now, utilizing deep-learning AI fashions, software program can create not solely realistic-sounding voices, but additionally convincingly imitate present voices utilizing small samples of audio.
Alongside these traces, OpenAI simply introduced Voice Engine, a text-to-speech AI mannequin for creating artificial voices primarily based on a 15-second section of recorded audio. It has offered audio samples of the Voice Engine in motion on its website.
As soon as a voice is cloned, a person can enter textual content into the Voice Engine and get an AI-generated voice outcome. However OpenAI shouldn’t be able to broadly launch its expertise but. The corporate initially deliberate to launch a pilot program for builders to join the Voice Engine API earlier this month. However after extra consideration about moral implications, the corporate determined to reduce its ambitions for now.
“In keeping with our method 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 typically shouldn’t be notably new—we have covered several AI voice synthesis fashions since 2022, and the tech is lively within the open supply neighborhood with packages like OpenVoice and XTTSv2. However the concept that OpenAI is inching towards letting anybody use their explicit model of voice tech is notable. And in some methods, the corporate’s reticence to launch it absolutely could 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 customized speech choices, and helping sufferers in recovering their very own voice after speech-impairing situations.
But it surely additionally signifies that anybody with 15 seconds of somebody’s recorded voice may successfully clone it, and that has apparent implications for potential misuse. Even when OpenAI by no means broadly releases its Voice Engine, the flexibility to clone voices has already prompted hassle in society by way of phone scams the place somebody imitates a liked one’s voice and election campaign robocalls that includes cloned voices from politicians like Joe Biden.
Additionally, researchers and reporters have shown that voice-cloning expertise can be utilized to interrupt into financial institution accounts that use voice authentication (reminiscent of 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 several major banks in Might 2023 to inquire concerning the safety measures banks are taking to counteract AI-powered dangers.
