I use the VocilizerEX TTS with the high premium voice of Melina and the vocalizer_e.tts_1.0.2.3t.apk. I want to use the newer VocilizerEX2 and I have found 2 different versions. The vocalizer-voice-melina.nvda-addon which is 750MB and the VocalizerExpressive-2.2.121-grg-Melina-PremiumHigh-enu.msi with the vocalizer_e2.tts_1.0.2.3t2.apk

What is the difference between VocilizerEX2 and Vocilizer expressive? They both work with nextgen and which is the best?
The vocalizer_e2.tts_1.0.2.3t2.apk works with both versions?
Thank you.
