This one is related to PortAudio V19 and depends on the current chipset.
The PortAudio mailing list has been contacted.
In principle, this issue  only affects the command line (or
Speech-Dispatcher or gnome-speech).

Could you please indicate which is your sound chip or audio card?

This behaviour might be hopefully improved in eSpeak for some chipsets.
Otherwise, patch might be offered to PortAudio.

A little bit of development time is needed.
