I did a full whipe and reset of the phone and checked the sound levels with no luck.
Then I noticed when placing a call my phone says "llamando" which is spanish for "Calling" and everything myphone read to me was in english but awkwardly spoken, as if a spanish person would be reading, hahahaha. So, thats was the second clear clue.
Then I went to languages and inputs and checked "text to speech output", then, "motorola tts" and it offered me only spanish and portuguese languages.
It seems that the OTA update to android 4.4.3 had only those options, maybe because OTA detected my latin amaerican carrier (movistar, Chile).
What I don't know for sure is if before, when moto assist worked just fine with 4.4.2, was by default in english.
Is there a way to add languages to motorola tts? Any stock motorola rom from another country that would work just fine with my XT1058 that surely would use english TTS?
