Send a piece of text in a simple GUI through a text-to-speech engine (producing spoken output). At the same time as each word is being spoken, highlight the word in the GUI. (The GUI does not need to be interactive, but some extra kudos for allowing users of the code to provide their own text.)
AutoHotkey
We use the simple SAPI.SPVoice COM Object and a parsing loop. The highlighting is done with EM_SETSEL and Notepad. Rather crude, but it works. Due to the simplistic nature of the parsing loop, the text ends with a space. <lang AutoHotkey>SetTitleMatchMode 2 EM_SETSEL := 0x00B1
Run notepad,,,pid WinWaitActive ahk_pid %pid% ControlSetText, Edit1, % text := "AutoHotkey was the first to implement this task! ", ahk_pid %pid%
pVoice := ComObjCreate("Sapi.spvoice"), i := 1 ; the spvoice COM Object ships with the OS
- parse the text
While lf := SubStr(text, i, 1) {
If lf = %A_Space%
{
SendMessage, EM_SetSel, % i-StrLen(word)-1, % i-1, Edit1, ahk_pid %pid%
pVoice.speak(word), word := "", i++
}
Else word .= lf, i++
}</lang>
