Google on Thursday launched Google Talk with video and voice chat for Android phones. “You can now video or voice chat with your friends, family and colleagues right from your Android phone, whether they’re on their compatible Android tablet or phone, or using Gmail with Google Talk on their computer,” Google said in a blog post.

Google Talk voice and video chat will work over 3G and Wi-Fi, provided your carrier supports it, according to Google. The feature will initially be available on the Nexus S, and Google said it will gradually roll out the feature in the next few weeks as part of the Android 2.3.4 over-the-air update. It will come to Android 2.3+ devices in the future.

To access, a video or voice chat button will appear next to the people in your Google Talk friends list; just touch the button to connect. Text chats you receive will be overlayed on top of the screen, so you don’t have to leave a video to read them. If you need to check something else, the video will pause but the audio will continue.
