The Speech Display Bar (SDB) displays text that you enter or generate in the app. There are settings to change the size of the text, increase the number of lines of text, and add highlighting to text that appears in the SDB.

Select Menu > Settings and scroll to the Speech Display Bar section.
Under Font Size, select a larger font size. Font sizes range from 14 Point to 72 Point.
Create a Tap Action to Enlarge Text
Select Menu > Settings and scroll to the Speech Display Bar section.
Under Tap Action, select Speak and Enlarge Text.

Increase Number of Lines for Text in the SDB
Under Number of Lines, select the number of lines of text you want to appear in the SDB. The number of lines ranges from 1 Line to 10 Lines.
Note: If you try to select a font size and number of lines that together would make the SDB larger than the screen can accommodate, the font size will be adjusted down automatically to a value that allows the SDB to fill no more than 60% of the screen. For example, if you select 10 lines with a 72-point font, the font will be adjusted to a smaller size.
Highlight Spoken Words during Phone Calls/FaceTime
