OpenAI.fm
OpenAI's interactive demo for trying its text-to-speech models, letting users type instructions and scripts, pick voices, and hear AI-generated speech instantly.
About
OpenAI.fm is a web-based demo from OpenAI for experimenting with its speech-generation technology. It addresses a common problem for anyone building voice experiences: text-to-speech systems have traditionally offered little control over how a line is delivered, such as tone, pacing, or attitude. The demo shows how these qualities can be shaped with natural-language instructions rather than technical settings.
Built by OpenAI, the page lets visitors write a short instruction describing how the speech should sound (for example, the speaker's manner or emphasis), enter the text to be spoken, choose from a set of available voices, and play back the generated audio on the spot. The interface is intentionally simple, and the same underlying capability is available to developers through OpenAI's API, making the demo a practical preview of what can be embedded in real applications.
Key Features
Pricing & Fees
- Pricing: Not publicly listed on the pages we reviewed; check the official site for current plans. The demo itself is presented as a free-to-try experience, while API usage is billed separately by OpenAI.

- Intended use: The page is positioned as a demonstration and experimentation tool rather than a full production voice platform.
Who It's For
OpenAI.fm is aimed primarily at developers who want to evaluate OpenAI's speech-generation models before wiring them into an application. Product teams and UX designers can use it to prototype voice interfaces and demonstrate tone control to stakeholders. Content creators, voiceover artists, and educators exploring AI narration or accessibility features can also test how natural-language instructions shape delivery. Anyone who needs a quick, hands-on sense of what modern instruction-following text-to-speech sounds like will find the demo a convenient starting point.
