I'm using 1.50, but I tried with both 1.49.2 and the latest development 
version 1.51-dev. But None of them were better.


I don't know why it is working worse for me than some others, but I 
think it may depend on the fact that I'm using an arm architecture.


What functions are brltty calling from espeak-ng? It might be a good 
idea to create an simple c- or python-file which can reproduce the 
error. Then it might be easier for the espeak-ng devs to find the 
problem in there source code.
