7.7.3 Volume Change

The speech volume can be changed by sending SPI command to modify the speed or by adding

control character to control the volume in real-time.

0x16 ^V

Volume Change Flag. A space character is required after the control characters

before the input text string.

•

^V+: Increase volume by 1 (e.g. ‘^V+ Hello world’).

•

^V-: Decrease volume by 1.

•

^VX: Set the volume to X. X starts from 0 to 7 (e.g. ‘^V1 Hello world’).

Any number that is greater than 7 will be set to 0.

It’s the user’s responsibility to verify the WTS701 volume setting before sending a control character

and/or SPI command that modify volume.

7.7.4 Case Sensitivity

The way upper/lower case is handled can be changed by adding a control character in the text sent to

control the case sensitivity behavior in real-time.

0x15 ^U

All-Uppercase Word (all CAPs) Control Flag. This flag controls interpretation of strings

with all uppercase letters. A space character is required after the control characters before the acutual

input text string.

•

^U0: This is the default setting. Some all-uppercase words (all CAPs) are spelled out, but

others are treated as ordinary words, abbreviations, Roman numerals, ect. (e.g. ‘^U0 IBM

equals ‘i b m’).

•

^U1: Avoid spelling out all-uppercase words. Any all-uppercase word in the input string will

NOT be spelled out unless the system determines that the word is not pronounceable. In this

mode, there is no abbreviation support (e.g. ‘^U1 NOKIA’ equals ‘nokia’).

•

^U2: Spell out all words, regardless of case. All words in the input sting are spelled out in

this mode. There is no abbreviation support in this mode (e.g. ‘^U2 NOKIA’ equals ‘n o k i a’).

^U3: Force the all-capital words/strings to be spelled out regardless of string length. For

instance, ‘^U3 HELLO’ will be pronounced as ‘H’, ‘E’, ‘L’, ‘L’, ‘O’.

7.7.5. Pause Control

Pause control flage: ‘^QX’: Pauses with variant length can be added within a sentence by using the

‘^QX’ flag. ‘X’ is an integer which indicats the pause duration (‘X’ is 0.1 sec per unit). For instance,

‘^Q10’ will add in a 1-second pause.
