Spinvox, a UK-based company, started accepting this week users in the United States. The service, which is mostly distributed through cell phone carriers, converts voicemails to text for either email or SMS delivery. To see how the service works, visit this site, call the number, and leave a message. A few minutes later, the message will be posted to the blog! This is great efficiency tool, but can also be used to screen calls. While in a meeting, voice messages can be converted to SMS messages delivered to your mobile device, so you can elect whether or not to return the call right away. [thanks, techcrunch]

Of similar note is a lie detection software program developed by Kish Kish that works with Skype. The program analyzes voice stress levels in a similar way law enforcement and the military verify truth.
