Speech on Android

[JeeJeeStudio]

Hi,


i have a few questions on speech used on android:


1. can you use any available language or must the Android System be set 
on a language? (i suspect the first) i choose an english and dutch lang, 
first it worked, later it talked spanish...could be a mistake from me of 
course.

2. the list of available voice is filled with unrecoqnizable names like 
nl-nl-x-lgc-network or nl-nl-x-dma-local, how can we change this like 
male-female or with names like Hans-Cynthia-Ben-Susan


thanks

Jerry
