I'm sorry. My message must not have been clear. The niceness change helps in the case of choppy speech. It does not help in the case that I was going to open a bug about. The bug is that a large input to espeakup causes the synthasizer to stop speaking for a time measured in seconds. Depending on how much data is sent into espeakup it could be one second or a multiple there of.

Thank you for adding the renice to the package.

It would be good to taskset as  well, if systemd has a mechanism for this so we don't have a dependency on util-linux.
