I got an email from Desert Consulting, and he is definitely still developing Quick Voice and is currently working on a release that will support capitalization and other new features. Nice!

Until then, the best way to capitalize the first word is to dictate the word, "period," and then say the sentence you had in mind. The program knows to capitalize the word that follows the period, so you'll just have to go back and delete the opening "." Since deleting a "." can be a pain to select, I usually press the button and dictate, "Starting, period [and continuing what I really want to write blah, blah, blah]" which prints out: "Starting. Blah blah blah" Then it's easy to select text of "Starting." with a tap and delete. Also starting sentences with "I" or a name like "Megan" works, too. :-)
