Pascal to MCL, e.g., speech manager

[Repenning Alexander <ralex@tigger.cs.colorado.edu>]

Maybe I'm missing something here but how do I 
map 

FUNCTION  SpeakString( s: Str255): OSErr;
    INLINE $203C, $0220, $000C,$A800; 
FUNCTION SpeakText( chan:SpeechChannel; textBuf: Ptr; byteLen: LongInt): OSErr;
    INLINE $203C, $0624, $000C,$A800;

into deftrap? Are $0220 and $0624 the trap numbers?

More generally has somebody alredy gone through the trouble of 
creating an MLC interface for the new Mac speech manager?
