/* Speech routines by Russell Wallace 1988, developed from speech demo program
* in ROM Kernel Manual. Routines are as follows:
* openmouth () sets everything up - returns nonzero if error condition
* say (string) says a null-terminated character string
* closemouth () shuts everything down - don't use it if openmouth ()
* returned an error.
* Parameters for voice are contained in openmouth () and may be changed,
* so may MAXLEN if you have very long strings or all of them are going to
* be fairly short. Use +L if compiling with Aztec C. Requires presence of
* translator.library in system disk LIBS directory.
* This code may be freely used in writing Amiga programs. */
