60 This function creates a table called BytesUsed that holds the value that
61 describes the number of bytes required to hold one frame worth of data in
62 the WMF (non-IF2) frame format. Each table entry is the sum of the frame
63 type byte and the number of bytes used up by the core speech data for each
