Google Voice is an invite only service by Google that provides benefits like voicemail transcriptions, notifications, custom greetings based on the caller or the ability to share voicemails for all users who have created a Google Voice account and linked their existing phone number to it. There is also an option for a Google number for additional benefits like free SMS, blocking and recording calls, checking on the callers before picking the phone up and one number that rings all the phones owned by the user.
Google Voice for Google Chrome is an extension that allows access to several Google Voice features directly in the web browser.

The Google Voice extension for instance displays the number of unread messages on the Google Voice inbox, play audio alerts when new messages arrive (with the option to turn that feature off) and offers quick access to recent messages with transcripts and voicemail playbacks.

The extension furthermore allows the user to send free text messages and to initiate calls right from the extension menu by typing a number or contact name. Phone numbers on websites are made callable via Google Voice by clicking on them with the fallback option to highlight the phone number to use the click to call popup to call the number instead.

Google Voice for Google Chrome can be downloaded from the Google Chrome Extension gallery. Several of the features that might get annoying after some time, like the audio notifications of new messages or the automatic modification of phone numbers to links can be turned off in the extension’s options.
