I recorded my first 500 sentences tonight. Note, make yourself comfortable so that you can read the sentences and read-aloud while recording without much head movement. However, don't put the mic right in front of your monitor. If you do, there will be some notch filtering that can occur. The recording 'studio' that is part of the voicebank is quite simple to use. Note to the interested, it's no small task to record 500 sentences - it took me about an hour and a half to get it done. The overall amount is roughly 3500 sentences! So, I'm looking at probably 8 hours of time that I'll be putting in to this effort. I will say that the first 150 sentences or so took longer because of the way I was oriented and had to turn away from the monitor for each sentence. The next 350 went by much faster.
