When the default text-to-speech program (spd-say) speaks it is accompanied by noise/crackling/buzzing (and some echo), how to fix?

spd-say "Hello world!"

I'm running Ubuntu 17.10 on a laptop (Dell XPS 15). I haven't noticed any audio problems on this machine with any other application. I've done sudo apt dist-upgrade pretty recently so everything is pretty much up to date.

00:1b.0 Audio device: Intel Corporation 8 Series/C220 Series Chipset High Definition Audio Controller (rev 05)

> spd-say --version
spd-say: 0.8.7

> uname -sr
Linux 4.13.0-39-generic

The problem persists if I change the volume on the computer, but if I run the application randomly a couple of times with the parameters -i -50 (decreased volume) it goes away temporarily, but I am looking for a more permanent solution.

    It seems to be a bug in the combination of speech-dispatcher with pulseaudio. As a workaround you can set

    AudioOutputMethod "libao"

    in /etc/speech-dispatcher/speechd.conf.
