Public bug reported:

Running espeak if bluetooth is enabled via the panel applet and bluez-
alsa is installed slows down espeak sound output *significantly*...

With bluetooth disabled...

"A" way (not ideal! ;-) to resolve the problem is to simply remove the
bluez-alsa package:

$ sudo apt-get remove blue-alsa


Notes:

- I have no bluetooth audio devices within range or enabled.
- I have no ~/.asoundrc so unclear why I'm getting all the alsa cruft.

Attached is the output of 'sudo hcidump -XYt'.
