That's correct as eSpeak-NG uses libespeak0ng.so (not libespeak.so). Perhaps
you're trying to use the es (eSpeak) driver rather than the en (eSpeak-NG)
driver.

Yes, it should, because they're two completely different speech engines.

But that's because you're introducing an error into your system by pretending
that libespeak.so should really be libespeak-ng.so.

Are you sure you're using the latest development code? I just tested this and
the previous line is ineeed stopped before the next line is spoken. Perhaps
this was a bug in an older release.
