The WTS701 allows receiving control characters embedded in the text sent in the Convert command
to better emphasize word or alter meaning of sentence. The control characters supported are for
phonetic alphabet playback, speed, volume modification and case sensitivity behavior.
The WTS701 uses an intermediate phonetic translation represented as an alphabet that represents
phonemes and stress for each input word. This feature allows the text sent to the WTS701 to consist
of a combination of ASCII characters as well as phonetic alphabet. This capability offers the flexibility
to send words already processed for phonetic representation, achieving the desired pronunciation.
Phonetic strings can be sent directly to the WTS701. This can be done by embedding phoneme
strings in the text stream for conversion. To embed a phoneme string, the string must be preceded by
a control-P (^P, ASCII 0x10) character and terminated by a space character.
For example:
“The quick ^Pbr1Wn fox.”
The following table lists the phoneme symbols acceptable by the WTS701E (English software
version). As the acceptable phoneme symbols are language dependent, please refer to the specific
language User’s Guide for details regarding characters accepted and other development
considerations.
