Default [REQ] TTS Locale for voice recog. App re deaf users

Ok. My speech is not normal as far as Googles definition of normal American English dialect. It is "deaf" sounding. I've never been able to get my phone to understand me for any command. I tried EDWINs app and I've given up...so I come to you to see what needs to be done.

How do I create my own library?

Thanks
