About igo: I don't use TTS in igo. I have the simple voices working. The problem with my igo was online search. I fixed it with a few adds in the sys.txt file.
Now about Sygic: I only refered to my s3 as rooted in order to inform everyone who is willing to help me that i can edit android system files. As far as i know in order to make tts voices work i must have installed or preinstalled some tts engines. According to android's text to speech settings my tts engines are samsung's and google's. Is sygic working with these or should i install another one?
I have copied LoquendoTTS folder into my internal storage. I opened Sygic and it didn't recognise any. I moved it into my external sd card and nothing again. My sygic folder is in internal storage. I moved it to external sd nothing again.
About the s3 i9300: I have flashed it again from the beginning with its original samsung rom without rooting it in order to test sygic again, But when i opened sygic it didn't recognise the voices.
Can you help me with these info?
Sorry for not mentioning that my language is greek.
