TEXT TO SPEECH ONE LETTER AT A TIME

you could use apple script to do this. can you describe how you would want this to work?

Launch AppleScript and create a new document. Then paste this into the new document and save it.

tell application “Finder"

set theTextToSpeak to text returned of (display dialog "What text do you want me to say?" default answer "text to speak.”)

repeat with aCharacter in theTextToSpeak

set theCmd to "say \"" & aCharacter & "\”"

do shell script theCmd

end repeat

end tell

Without the smart quote before Finder, or after speak, and without the Finder tell block or do shell script. 😉 It will pronounce umlaut if a diacritical character (e.g. ö, etc.) is encountered by casting each character to UTF8. Does not pronounce spaces, or punctuation in words though.

use scripting additions

set theTextToSpeak to text returned of (display dialog "What text do you want me to say?" default answer "text to speak.")

repeat with aCharacter in theTextToSpeak

sayaCharacter as «class utf8» using "Victoria" speaking rate 110 pitch 54 modulation 80

end repeat
