For the past few months Google has been in the process of integrating WebRTC into Chrome. WebRTC allows webcams and microphones to connect with the browser without using Flash. Chrome 25 also comes with WebSpeech API, which allows us to use voice commands using a simple snippet of JavaScript.
The long wait is finally over and you can officially start downloading the new Google Chrome Beta. Google also has a Chrome Beta channel available for tablets and smartphones running on Android 4.0+.
