About Text Templates

The Text-to-Speech device produces real-time dynamic speech from a text template file. This file can contain three components, each of which handles a different task (see below).

See Before Creating a Template for more information.




The text represents the words that are spoken. This device provides an electronic dictionary to instruct the speech engine how to pronounce the words. See Modifying the Dictionary for more information. The text analysis capabilities of the system detect the ends of sentences, perform some rudimentary syntactic analysis, expand digit sequences into words, and disambiguate and expand abbreviations into normally spelled words which can then be analyzed by the dictionary-based pronunciation module.

control tags

Also called speech engine control tags. These commands are used to better simulate human speech by improving inflection, accent, timing and other factors that affect speech quality.


Also called V+ commands. These are used to control speech based on data within V+, by allowing dynamic control over the speech output, via ports found in the V+ design and referenced in the text template.
