The file VOICE.C contains a major subroutine "talk" which enables the
user to operate a Votrax SC-01 speech synthesizer chip phonetically. That is,
the subroutine takes as right argument a character string made up of the
Votrax standard phoneme descriptors. For example the statement
talk("T,EH,N,PA1,"); (the trailing , is mandatory)
will say the word ten. Note that without the final PA1 the synthesizer will
say NNNNNN.... if you use a latched scheme like I do.
Some other subroutines to make life easier are included. They are
[1] saynum(num) will pronounce a number (num is unsigned integer)
[2] sayday(dayow) will say the day of the week (dayow is char 0-6)
[3] saymonth(month) will say the month (month is char 0-11).
No doubt this could be sped up in some way, but it simplifies
code. Especially if you want to write an interactive program to check out
various phoneme combinations. The routine "pronounce" assumes that you have
the chip set up as a LIST device when IOBYTE is set for UC3: . I.E. setting
STAT LIST:=UC3: on my micro gets the Votrax ready for LIST output. This
routine will most likely need changing on your machine, although this route is
convenient for interfacing less tolerant languages as STAT can do all the
work.
Easiest method of use in BDS-C is to compile VOICE.C separately and CLINK
it to whatever routines you write to use the synthesizer.
