OpenAI has debuted three new models for transcription and voice generation — gpt-4o-transcribe, gpt-4o-mini-transcribe and gpt-4o-mini-tts. The text-to-speech and speech-to-text AI models are designed to help developers create AI agents with highly customizable voices. OpenAI claims these models will power natural and responsive voice agents, moving AI out of the text-based communications stage and into intuitive spoken conversations. The suite outperforms existing solutions in accuracy and reliability, OpenAI says, especially with “accents, noisy environments, and varying speech speeds,” making them well-suited for customer call centers and meeting notes.

Sesame, an AI startup from Oculus co-founder Brendan Iribe, has created a conversational voice model that many feel has achieved uncanny levels of authenticity. Drawing comparisons to the charismatic vocal centerpiece of the 2013 Warner Bros. film “Her,” Sesame seems to have achieved a new level of engagement among AI voice assistants. While some are describing the tech as “amazing.” others have expressed concern over its capabilities. “Our goal is to achieve ‘voice presence’ — the magical quality that makes spoken interactions feel real, understood and valued,” explains a blog post by Iribe and others.

OpenAI has debuted a new text-to-voice generation platform called Voice Engine, available in limited access. Voice Engine can generate a synthetic voice from a 15-second clip of someone’s voice. The synthetic voice can then read a provided text, even translating to other languages. For now, only a handful of companies are using the tech under a strict usage policy as OpenAI grapples with the potential for misuse. “These small scale deployments are helping to inform our approach, safeguards, and thinking about how Voice Engine could be used for good across various industries,” OpenAI explained.
