I've had a tablet now for about a week - my first experience of Android. I posted earlier explaining that I could not change the default TTS engine used and unfortunately I have still not found an answer to the problem. I have installed Ivona and also Svox and in the settings tried to change to one of these, but no luck. When I tap on an alternative, the selection remains at the default Pico. I cannot imagine why, but is it possible that the manufacturer may have disabled the ability to change, or am I missing some other possibility. Any input would be greatly appreciated.
