Google is announcing a new service - Google Voice. Apart from the automatic transcripts of voicemail, call filtering and other user benefits, the service will give Google access to enormous amounts of information about your life - including recordings of your voice mail.
Of course, the Google creed is - Do no evil! But let's dig deeper into what Google will get their hands on:
Records of voice mail calls, with automatic transcription - Google will have the voice AND a searchable text of your messages, possibly even your calls at some point
Voice imprints of all the people who called you - and they can match those imprints to a source phone number.
FULL listing of your incoming call list - since Google Voice is a service integrated with Grand Central (Google Number) which creates one single number and when the caller rings that number, you can select up to 6 phones to ring simultaneously.
