Sorry I miss a not in "You said PremiumHigh is necessary", I want to know how and where the PremiumHigh can do?
I just download the Android-VocalizerExTTSPro-English(UK)-Daniel(male) .rar, copy and install as your instruction, it turns out igo can not see this voice. Some other TTS voice can be seen, for example, that unisex voice English-UK_universal_unisex_andTTS-Boki_Srb_v.1.zip, I know you know that file.
I saw you update every your post very fast, so I thought Android-VocalizerExTTSPro-English(UK)-Daniel(male) .rar is all new and correct one.
I will try again, thanks very much for your quick reply.
