Google Inc is seeking to blur the line between the telephone and the computer even further with yesterday's introduction of Google Voice.

The new service weaves traditional phone features with Google's Gmail email product, allowing a person to store transcripts of voicemail phone messages in their email inbox and to find a specific nugget of information within a phone message as if trawling through a sea of emails.

The move comes as Google increasingly branches out from its stronghold in Internet search, as it seeks to carve out a role in everything from cell phones to personal productivity software.
