Is it possible to change the tts voice (from robotic to more natural) either via phone settings or an app? Thanks
Settings - Accessibility - Text-to-speech output - (cogwheel next to Preferred engine) - Voice variant (and all the other settings there)
See here for suggested settings and perhaps different engines to install …
Thank you, the link led to very useful info. I could not get an acceptable voice tone by tweaking the e-speak settings. However, I have installed IVONA tts engine (from info contained in the linked topic) and the voice is excellent. Rather an involved procedure for me, being not particularly tech-savvy, but the result was well worth it.
