TTS is working for me on my M96 on the Booxstor edition from Oct 13th.
It didn't work out of the box.
I went to Android Settings -> Personal -> Language & input -> Speech -> Text-to-speech output.
Under 'Preferred Engine', it was only showing me 'Pico TTS', because I don't have Ivona or other TTS engine installed.
Under its settings, there was an option to install the speech files. Clicking on it brought me to the app on Google Play Store. I installed it & it works now, although its pretty robotic sounding.
