To apply the Accessibility Sync Caption behavior:
Apply the keyboard navigation behaviors to sprites in your scene. For more information, see
1
"Enabling keyboard navigation" on page 553.
Apply the text-to-speech behaviors to sprites in your scene. For more information, see
2
"Enabling text-to-speech" on page 555.
Drag the Accessibility Sync Caption behavior from the Library palette to the sprite that will
3
trigger the text-to-speech feature. This could be a text sprite that has the Accessibility Speak
behavior attached or another sprite that will trigger speech with the Accessibility Speak
Member Text behavior attached.
In the dialog box that appears, select the behavior group name for the scene. This associates the
4
accessibility behaviors in the scene with one another so they work properly.
In the first At Word text box, enter the number of the word in the text that will be spoken
5
where you want the captioning to begin. For example, if you want to begin captioning at the
first word of the spoken text, enter the number 1.
In the Initial Words text box, enter the number of words to display after the starting word
6
number that you selected in the previous step. This is the number of words that can appear in
the captioning sprite when the captioning begins. For example if you want the first section of
text to begin at the first word and end at word 15, enter 1 in the previous step and 15 in the
Initial Words text box. These words are replaced in the captioning display sprite by later
sections of the text being spoken. You select the number of words in each section by using the
remaining text boxes in the dialog box.
In the next At Word text box, enter the number of the word where the second section of text
7
you want to display begins. For example, if you want the second section of displayed text to
begin at word 16 of the spoken text, enter 16 in the At Word text box.
In the Display How Many of the Words That Follow text box, enter the number of words to
8
display after the word number you selected in the previous step. For example if you want to
display 22 words of text after word 16, enter 22 in this text box.
In the remaining text boxes, enter the numbers of the first word of each section of text followed
9
by the number of words in each section. To use more than five sections, drop this behavior on
the sprite again. This procedure can be repeated as often as necessary.
When you have finished entering values in the dialog box, click OK.
