Can I synthesize arbitrary text strings with TTS from the Android's console?
To give the idea, on Debian I would do:
The TTS engine needs to be always available and run offline, thus Google TTS is not an option. The phone is a "Samsung Galaxy Fame gt-s6810p" with Android 4.1.2; it comes with an offline Samsung TTS engine installed.
I tried SimpleTalker (URL to GitHub forbidden), a cmdline TTS proxy over Android's synthesis engine, but apparently it's bugged.
