So: Set Google Translate to English, then click the microphone that appears in the lower right-hand corner of the input box. One other hitch is that because this is a brand-new feature, it's also limited at present in Google Translate to translations originating in English. Expect that to change as site developers begin to implement the feature. Currently, that's limited to Google Translate, which itself is limited to translations that originate in English. Next, you have to navigate to a site that supports the new speech API. First off, be sure that you're using Google Chrome 11 ( download for Windows | Mac | Linux)or later, and that you've got a microphone.
