Google Talk is a lightweight Jabber-based instant messaging client with voice capabilities. Google Talk is easy and intuitive to use. All you need to make free calls is an Internet connection, a microphone, and a speaker. After you download Google Talk, sign in with your Gmail username and password. Invite your friends to download Google Talk, and once they do, you'll be able to talk or IM with them instantly.
Google Talk currently does not encrypt chats or calls. When you use Google Talk, you can choose to have your IM chats stored locally on your own computer so that you have a chat history. Google does not collect the content of instant message chats or voice conversations.
They say talk is cheap. Google thinks it should be free. Google Talk enables you to call or send instant messages to your friends for free–anytime, anywhere in the world. Google Talk offers you:
Choice: Get in touch over email, IM or a call
Quality: Talk through your computer but hear your friends as if they were in the same room
Convenience: Your Gmail contacts are pre-loaded into Google Talk so inviting or talking to your friends is just a click away
