Voxa

Voxa is a free Chrome extension that lets you type with your voice on any website. Click into any text box (email, chat, forms, comments — anywhere you can type), tell Voxa to listen, speak naturally, and your words appear as text. You can even pick an output language: speak English and have Portuguese, French, Japanese (or any of 80+ languages) inserted instead. No accounts. No sign-ups. No configuration.
