To check whether the speech is currently speaking, paused, or stopped:
•
Use the
voiceState()
function.
To set the volume of the voice:
•
Use the
voiceSetVolume()
command.
To set the pitch of the voice:
•
Use the
voiceSetPitch()
command.
To determine the chronological number of the current word within the string being spoken:
•
Use the
voiceWordPos()
function.
The following frame script tests whether the current voice is female and starts speech if it is. In
this case the
voiceSpeak()
command specifies the text of the cast member named
“TextCommentary”.
on exitFrame
voiceProps = voiceGet()
if voiceProps.gender = "female" then
voiceSpeak(member("TextCommentary").text)
end if
end

Deploying accessible movies
To successfully deploy an accessible movie, you become familiar with the Speech Xtra’s system
requirements and download procedure as well as the experience users will have with your
accessible movie in real-world situations.
Adding the Speech Xtra
If you use the text-to-speech feature in a projector, you need to include the Speech Xtra in your
movie’s Xtra list. Normally, Xtra extensions that are not included in a movie’s default Xtra list are
added to the list when a cast member that requires one is added to the cast. You can view the
default Xtra list by opening a new movie and selecting Modify > Movie > Xtras.
The Speech Xtra is a Lingo-only Xtra, which means that it adds commands and properties to
the Lingo scripting language but does not add support for any new cast member types. Because
the Speech Xtra is not associated with any kind of cast member, you must add it to the movie’s
Xtra list manually.
