I downloaded this new Personal Audio Link app. They issued a press release looking for beta testers, with a compensation offer of 6 months free Vonage service for qualified testers.
I'm posting this because they are seeking more beta testers, particularly seeking "power-users" who understand the technology.
It uses a SIP client for speech interaction. One can send and receive e-mail by voice, get instant local traffic reports, instant local weather, listen to podcasts, blogs, RSS feeds when navigating by voice.
I'm a speech recognition user, and am using it now, dictating e-mails with 98% accuracy, even with significant background noise, or wind noise.. using a cell phone.
