Hello,
espeak-ng used to have overlapping speech synthesis issues (#848016):
e.g. while moving fast in a list of items, the speech of each item would
get mixed with the previous one, making it difficult or impossible to
hear. We reduced the buffer size of espeak-ng from 200ms to 50ms to
considerably reduce the issue.
However, the modified buffer size happened to break the use of mbrola
voices (#860891), so we raised it a bit, from 50ms to 60ms, like
upstream did, to fix that.
However, that brought back some of the overlapping issues, making it
tedious to use...
(https://lists.debian.org/debian-accessibility/2017/06/msg00002.html)
I have thus uploaded a version -11 of espeak-ng (attached debdiff) which
reduces it to 49ms, which avoids the overlapping regression, and which I
have tested as working with all mbrola voices.

This contains udebs, so Cc-ing KiBi for the udeb ack.
