I think it's hard to understand what many people say, with all the abbreviations and the wannabe ghetto-slang And it's takes probably more time than to just write it. Except if you push a single button (on PC of phone) and as long as you hold it, it's recording. When you stop to push it will be sent. That would be the fastest way.
It could work when everyone who uses it speaks understandable
I love this, and just read an article yesterday that motivates me too do this with you - the article suggested how in the near future, we will not use remote-controls for TVs, etc; it will all be hand gestures and... VOCAL COMMANDS. Voice recognition is improving, let's get in on this now. Brilliant idea, though it will be a big challenge, Eric. SKYPE osakasaul or gtalk firstname.lastname@example.org and we'll talk on the Facebook API - as soon as possible.
