include all the sounds you want to use in a single project.
Speaker Independent Custom Vocabularies
The set of built-in Speaker Independent recognition vocabularies can be expanded with custom grammars,
that you can create with the QuickT2SI
TM
tool (a separate license is required to use the software).
When you create a QuickT2SI
TM
project, you are presented with a list of words or short phrases (also called
“commands”) and an optional trigger word/phrase. The so-called “trigger” is a special set that contains
only one word or phrase, with an improved recognition performance, that is used as an entry point for any
vocal interaction with a device that is continuously listening to the user’s voice.
If you need to use a trigger word, it is important to carefully choose it so that it has good performance,
with very few unintended activations and a high recognition rate. When the user says the trigger word
followed by a command, the system can discard unintended activations when the trigger is not followed
by a command within a short amount of time (usually around 3 seconds). Moreover, there is only one
trigger word to listen to, instead of a list of several commands, so the chance to pick up a random
command from background noise or talk is also lower, when using a trigger word.
