OpenAI Text To Speech WebUI Product Information

OpenAI Text to Speech WebUI Frontend

This is a free frontend web UI for OpenAI's Text-to-Speech (TTS) API. It allows users to input text and generate speech using OpenAI's TTS models. Users must provide their own OpenAI API key. The project aims to offer an approachable interface to synthesize speech in a variety of languages and voices supported by OpenAI's TTS service.


How it works

  • The app acts as a frontend that calls OpenAI's Text-to-Speech API using your own API key.
  • You paste or type the text, select the language/voice options available, and the UI sends a request to OpenAI's API to generate audio.
  • Generated audio can be played in the browser and downloaded if supported by the frontend.
  • Because it relies on your API key, you control access and usage per your OpenAI account policies.

Supported languages

OpenAI TTS supports a wide range of languages. The UI exposes the language options available from the API, enabling multi-language speech generation.


Who is it for

  • Digital marketers, product creators, or developers who want a lightweight, browser-based TTS testing ground.
  • Teams that want to prototype speech-enabled content for product videos, tutorials, or accessibility features.

How to use

  1. Obtain an API key. Get an API key from the OpenAI Platform.
  2. Open the WebUI frontend. Load the app in your browser.
  3. Enter text. Type or paste the content you want spoken.
  4. Choose language/voice. Select from available languages and voices.
  5. Generate speech. Click to synthesize and listen to the result.
  6. Download (optional). Save the generated audio file if the UI provides a download option.

Note: This is a free frontend for OpenAI’s TTS API. API usage incurs OpenAI charges according to your account plan.


Safety and usage considerations

  • Use TTS responsibly and in compliance with applicable laws and OpenAI terms.
  • Avoid generating or distributing content that could be harmful, defamatory, or violate privacy or consent.
  • Do not share your API key publicly.
