I have had approx 15 or so different people leave messages, and of those “testers” all women voicemails came through fine, and the men were a hit or miss just based on pitch… such as, of some that failed, I had them call again and say the same verbage just in a more “happy” (for a lack of better terms) tone and then the transcription worked semi-well. It was somewhat still hit or miss on some words but it got a majority of what was said.

Thus far, I’m impressed, but it still requires much more fine tuning before I am willing to just read those transcripts instead of actually taking the time to download and listen to the voicemails.

Hope this helps.

There are apps available (for the iPhone, windows mobile, blackberry) that give you a dial pad interface to initiate calls from your GoogleVoice number (google voice would ring your phone first, then once you pickup, it will connect you to the number you dialed). iPhone Grand Dialer: http://mickeypapillon.wordpress.com/2008/08/05/great-iphone-app-grand-dialer/

@Jeff — it actually does, however it only shows one line, and that line only is as long as the embedded player is wide. What would be nice is if they could let the player ‘caption’ expand vertically to fit the entire transcribed text!
