Google Voice offers so many features, it can be confusing for newbies. CNet gets you started and points to Google’s own excellent Help pages.
“Google Voice is best known for its visual voice mail features. If you miss a call, Google Voice uses computers to transcribe the voice message into text, which it can send to you via SMS or e-mail.
You can read or listen to messages in any order you like and the messages, which are stored online on Google’s servers, and are accessible from any browser, including the browser on your mobile phone (see video at left for more details.)”
