OpenAI Text To Speech WebUI

OpenAI Text To Speech WebUI is a simple web interface that lets you convert text into speech using OpenAI's Text-to-Speech API. You type or paste your text, choose from six voices (Alloy, Echo, Fable, Onyx, Nova, Shimmer), pick a quality level (HD or standard), and hit convert. The tool then sends your text to OpenAI's servers and plays back the generated audio. It's a straightforward wrapper — no accounts, no subscriptions, just a clean UI for OpenAI's TTS service.

The tool requires your own OpenAI API key, which you paste into the browser. You can optionally save it locally (though the site warns against it). It supports over 60 languages, from Afrikaans to Welsh, and the voices are the same realistic ones used in ChatGPT's voice mode. The interface is minimal: a text box with a character counter (up to 4096 characters), a voice selector, and a convert button. There's no history, no file management, no batch processing — it's designed for quick, one-off conversions.

This is ideal for developers, content creators, or anyone who needs to generate natural-sounding voiceovers without paying for a full TTS subscription. You can use it for product demos, social media videos, e-learning narration, or accessibility tools. Since you bring your own API key, you only pay OpenAI's usage fees — the web UI itself is free. If you already have an OpenAI account and want a no-fuss way to test their TTS voices, this is a handy tool to bookmark.
