Programming note: This REXX program uses a freeware program NIRCMD to interface with the Microsoft Windows speech synthesizer program '''SAM''', a text to speech using a male voice. SAM can possibly be configured to use other voices with later releases of Windows. More recent Microsoft Windows have another speech synthesizer program: ANNA.
Each word of the text is highlighted (by showing the word in uppercase). the terminal screen is cleared before showing the text that is being spoken; the repeated calls to the (Windows) speech engine makes for a slower speech rate.
<lang rexx>/*REXX program uses a command line interface to invoke Windows SAM for speech synthesis.*/
parse arg t /*get the (optional) text from the C.L.*/
#= words(t)
if #==0 then exit /*Nothing to say? Then exit program.*/
dq= '"' /*needed to enclose text in dbl quotes.*/
rate= 1 /*talk: -10 (slow) to 10 (fast). */
/* [↓] where the rubber meets the road*/
do j=1 for #
x= word(t, j); upper x /*extract 1 word, capitalize it for HL.*/
if j==1 then LHS= /*obtain text before the spoken word. */
else LHS= subword(t, 1, j-1)
if j==# then RHS= /*obtain text after the spoken word. */
else RHS= subword(t, j+1)
'CLS' /*use this command to clear the screen.*/
say 'speaking: ' space(LHS x RHS) /*show text, one word is capitalized. */
oneWord= dq x dq /*surround a word in double quotes (").*/
'NIRCMD' "speak text" oneWord rate /*NIRCMD invokes Microsoft's Sam voice*/
end /*j*/ /*stick a fork in it, we're all done. */</lang>
