Accessibility scripting with Lingo or JavaScript syntax
If you have a basic understanding of Lingo or JavaScript syntax, you can write custom scripts to
add text-to-speech functionality to your movies. For more information about Lingo and
JavaScript syntax, see the Scripting Reference topics in the Director Help Panel.
First, you must initialize the speech software.
To initialize the text-to-speech software:
•
Use the
voiceInitialize()
method.
The following frame script tests whether text-to-speech software is installed. If no software is
installed, the script displays an alert dialog box.
on exitFrame
if voiceInitialize() then
_movie.go("Start")
else
alert "Text-to-speech is not available"
end if
end
To determine the number of available voices:
•
Use the
voiceCount()
method.
To return a property list that describes the name, gender, age and index number of the
current voice:
•
Use the
voiceGet()
method.
To return a list of property lists that describes all the available voices:
•
Use the
voiceGetAll()
method.
To set a particular voice as the current voice:
•
Use the
voiceSet()
method.
After you select a voice for speech synthesis, you can control the progress of the speech.
To begin speech synthesis:
•
Use the
voiceSpeak()
method.
To temporarily pause the speech:
•
Use the
voicePause()
method.
Some speech engines might continue to speak for several seconds after the pause method
is used.
