What is the Web Speech API?

The Web Speech API is a JavaScript API within browsers that allows websites to perform speech recognition.

Web Captioner uses the Web Speech API for quick client-side speech recognition. Because Web Captioner is the kind of product that I think most people would use in an environment where they have control over their browser choice (instead of a restricted enterprise environment, for example), and because Chrome is a modern browser with wide adoption, I’ve decided to focus my development effort on making Web Captioner work great in Google Chrome.
