Can we increase voice volume?

[Daireaux]

I have purchased the Cepstral David voice and it is rather low in volume compared to the other Windows sounds my computer makes. Is there a way within Hal to increase Just his spoken voice volume? The Cepstral volume, pitch, and speed controls available through the SwiftTalker configurations change text to speech qualities but don't seem to affect the voice coming out of Hal. I need to boost just Hal.
