Whisper Text Reader is a lightweight Chrome extension that turns highlighted web text into spoken audio using the OpenAI Whisper API. You supply your own OpenAI API key, pick a voice in the popup, then right-click any selection and choose "Read this text aloud."
Highlight any text on a web page, right-click, and pick "Read this text aloud" to hear it spoken immediately — no copy-and-paste into another app.
The extension supports several Whisper voices that you choose from the popup, so you can match the tone to the content.
The extension is a thin client for the OpenAI Whisper API and is billed at OpenAI's standard API rates rather than a separate monthly fee.
The extension requests no broad data collection and declares that your data is not sold or shared for unrelated purposes.
