In October, UK-based speech-to-text (STT) provider SpinVox launched a free service that allows Facebook users to make changes over the phone to their accounts or profiles. SpinVox hopes its success in those areas will carry over to social networking. But it's a gamble. Though mobile devices keep users constantly connected to the Web, STT software has yet to venture further than basic applications like SMS, voicemail, and email. So far, speech apps via the Internet haven't caught the Web 2.0 generation's interest. And with SpinVox planning to offer a paid-subscription option in the near future, some wonder not only if the demand is there, but also whether younger users will pay.
