Delphi and DSP

This question is about Digital Signal Processing (DSP) and not meant for this group, but I would still ask because I will be implementing the solution to this question in Delphi. Probably someone on the group has already tackled this problem...please pardon me if I am a bit vague.

My application will be receiving alpha-numeric data from the COM port in realtime. The application is responsible for converting this data into a sound. (Please note that data is *not* to be converted into speech).

I am not an expert on DSP, but I envisage that I need to put the incoming data into the buffer of the sound card so that it can be played back. Another possibility is to create an in-memory wave file that can be played back.

I will appreciate any comments, or pointers to resources on this matter.
