Voice search in Chrome
The new browser extension Google Chrome "Voice search" allows you to search using your voice. The extension is not developed by Google, but uses a speech input form - an experimental feature of Chrome.
Voice Search ships with the following services by default: Google, Wikipedia, YouTube, Bing, Yahoo, DuckDuckGo, and Wolfram|Alpha. You can add your own search engines. The extension also adds a voice input button for all sites using HTML5 search forms. The extension requires a microphone to work.
Speech input is experimental, so it is not stable. In addition, you need to speak clearly in order for speech to be recognized better. Only English is recognized and the extension doesn't always work, but it's a good way to test features that will be included in future versions of Chrome. You can also add support for speech input to your own site, but it still takes time for this feature to become standard in other browsers.
