I ran the following:

$ make clean

$ git pull

$ ./configure --with-espeak=no

$ make

$ sudo ./run-brltty


The problem is more precisely that the speech isn't interrupted when I 
move to a new line. The lines are not enqueued as I said before. For 
example. Let say brltty reads a very long line and I walk 10 lines away. 
Brltty doesn't stop to speak the first line until it is done, but when 
it is done with the first line, it will start to speak the current line 
I'm at and not all lines in between.


I expect brltty to interrupt the speech immediately when I move to a new 
line. It is very strange if this is different on different systems. 
Maybe it is a problem in espeak-ng. I'm using espeak-ng 1.50.


I'm willing to help as much as possible to fix this problem because it 
is very annoying.


Best regards,

Tage
