The DOSUSB drivers by Georg Potthast include a driver which claims to  
support adapters with Prolific chipsets. I don't have such an adapter  
myself, so I don't know how well it works.

There is a program called VSB which emulates a Sound Blaster and sends the  
output to the PC speaker or a Covox Speech Thing (which despite its name  
is only a digital-to-analog converter connected to the parallel port).  
However, it is only compatible with real mode software, and even then not  
all of it. The quality, of course, is not that great, but it is probably  
good enough for speech.
