(rename downloaded file from *.nvda-addon to *.zip, extract, and copy to SD Folder structure as shown in my download)
Each language in it's own subfolder under VocalizerEx...enu = English US, etc
Note: "Compact" voices will not work with the "Premium" engine..only (probably) Plus and Premium High. I have not tested "Plus".
Download all RAR parts and extract on PC.
Copy entire VocalizerEx folder in download to the root of SD Card. Add any other voices/languages downloaded separately.
Install APK, go to Android Settings>Language and Input>Text to speech output> Enable VocalizerEx TTS, adjust voice settings as desired, etc.
All of this tested under KitKat on a medium range Android Phone. How it may perform under other circumstances is unknown.
