Special Characters in Text Input String
These characters inserted into the ASCII text are used to modify the behavior for special
circumstances.
0x10 ^P
‘^Ppr0Ez0Intles0In’).
0x11 ^Q
is an integer which indicates the pause duration (‘X’ is 0.1 sec per unit). For instance, ‘^Q10’ will add
in a 1-second pause.
It is important to remember that all the text following these special characters will be subjected to the
same special conditions. If a ^V+ command precedes a word then all the following words will be
spoken louder. If a single word is to be emphasized then the ^V+ must be ahead of the word and a
^V- must follow.
The rate of speech can be changed by sending an SPI command to modify the speed or by adding a
control character to control the speed in real-time.
0x13 ^S
the input text string.
It’s the user’s responsibility to verify the WTS701 speed setting before sending a control character
and/or SPI command that modify speed.
Examples:
