Phonical recordings for a vocal synthesizer please.

I have an idea to make a vocal synthesizer with blender to use in games, but I need the sounds of every letter in the English alphabet (at least 26). This project won’t be concerned with accuracy, but I’d like to have both male and female vocals for use within a game (numbers and numerical words will also help). If it is successful I’ll post a Let’s Blending tutorial, otherwise there’ll be nothing. Placing a textfile in the zip with your name will allow me to add you to the credits of any game I use this in. Please no GPL licensing. Ifyou don’t want to do every vowel type, I’d rather have long vowels than
