Does the quality of the text to speech voices improve when the operating system is upgraded to 2.1?



Also, what is the best text to speech app? I DON'T need an app that reads your texts. I need a text to speech app that speaks what you type into the phone, because I'm non-verbal.Does the quality of Text to Speech apps improve on Android phones when the OS is upgraded to 2.1?
Yes, the 2.1 version is much better but I am not sure of any good speech to text.
