SpeakGPT addresses a simple annoyance: the official ChatGPT web interface is text-first, so every question has to be typed. This extension installs a small toolbar layer and a dedicated talk page that add speech recognition and text-to-speech on top of the site you already use. You click the microphone, speak, and the transcript is submitted as a prompt; the answer is then spoken back through the browser's speech engine. Because it operates on your own logged-in ChatGPT session, there is no separate account, no API key to configure in the basic flow, and no second chat history to manage.
The extension exposes a small options page where you can choose the playback voice, set the recognition language code, and paste or validate a token. Voice choice matters more than it sounds: picking a language-matched voice and recognition code is what makes dictation usable for non-English speakers. A TikTok-style voice option is included for people who want a more playful read-aloud tone, and the same Chromium extension can be side-loaded into Kiwi Browser so the microphone flow also works on Android phones.
SpeakGPT is a hobby-scale tool. The Chrome Web Store listing shows a tiny install base and a single rating, updates are infrequent, and the extension is distributed as-is by an individual developer. It also offers in-app purchases, so treat it as freemium rather than strictly free. If you need a polished, supported voice product, look at OpenAI's own voice modes or a larger commercial dictation tool; if you just want a free talking interface for the web chat, SpeakGPT is a reasonable experiment.
