Hi there!
I haven't tried yet the newest 9.6.22.????? yet!
I simple use iGOprimo_v9.6.7.235654_thin-v1.0 and as I have seen so far I haven't find any bug in my Samsung Tablet 2 10.1 , in my Samsung Galaxy Y, in Htc desire and in so many devices that friends have tested in too many forums and use those voices.
As you said the loquendo works. So I don't know what is the exactly .apk you use and furthermore I don't know where you get this version you use 9.6.22.????? .
While loquendo works in your device, then this thread has did the job!
Goodluck please try another .apk or .apks ....
Moreover, to said you a secret , in order to have the TTS Pro active , the voice .zip file needed to have the function "ttsvoice=1" inside the info.ini file.
All of my voices that I have post here have this function and all of them have the TTS Pro menu active.
