Thanks. As speech-dispatcher in Slint by default sends it audio output 
to libao which sends it to alsa, I could compare the results with the 
ones I get sending the audio output to pulseaudio instead.

PS as an aside, with our default settings there should be no latency 
issue with Orca as pulseaudio doesn't come into play. Same for the
console screen readers (e)speakup, speechd-up and fenrir.
