Sound_InstallVoice

(SWI &40183)

This SWI can perform several different operations, determined by combinations of R0 & R1. Consult the table below for details.

R0	R1	Action
Pointer	-	Install voice generator
0	0	Find free voice slot
0	1-32	Read name of installed voice
1	-	Install voice generator, specifying its local language name
2	-	Read name of installed voice and its local language name
3	-	Change local language name of voice

Notes

If an error occurs, this SWI does not set V in the usual manner. Instead R1 is zero on exit, and R0 points directly to a null-terminated error string.
