Parser Selection
Emic 2 provides a choice of text parsing engines: Epson or DECtalk.
Both will process incoming text strings and generate synthesized speech, but there are differences in
control and customization of the resulting output. Each parser's specific functionality is incompatible with
the other. Choosing which parser to use ultimately depends on what sort of speech output you desire for
a particular text string.
See the Sample Text Strings section (p. 9) using specific features of the Epson and DECtalk parsers.
Epson Parser
The Epson parser is the default setting upon Emic 2 power-up. It allows on-the-fly, dynamic changes of
emphasis, pitch, voice selection, and speaking rate to take place within a text using embedded mark-up
control symbols:
\/
/\
>>
<<
__
##
:-)x
DECtalk Parser
The DECtalk parser is intended for advanced users and allows the finest control and customization of
speech output by providing direct access to the internal parameters of the DECtalk 5.0.E1 text-to-speech
synthesizer engine.
Dynamic customization using the DECtalk parser requires the correct usage of specialized commands and
their associated parameters. Incorrect usage of the DECtalk commands may result in improper or
unintelligible speech output. Please refer to the Epson/Fonix DECtalk 5.0.E1 User Manual available on the
Emic 2 product page for full command details and phonetic symbols.
Only a subset of the DECtalk commands are supported by the Emic 2 Text-to-Speech Module:
[:comma]
[:dv]
[:mode]
[:name]
[:period]
[:phoneme]
[:pitch]
[:pronounce]
[:punct]
[:rate]
[:say]
[:skip]
[:sync]
