Performs Speech Synthesis and Speech Recognition. The speech recognition operates on both words and variables because the output ports provide variable substitution at run time.

Summary
Use the Generic List Object when you wish to provide branching based on speech recognition but are using variables instead of fixed words or phrases in the recognition ports. The variable in the recognizer is substituted when the dialog reaches the object.
The following diagram shows the recognition port of a Generic List Object. Speech recognition is performed on the words, phrases and variables within the text box. In this case the variable named "answer" is substituted and recognition is performed on both "the value of the variable called answer" and the fixed phrase "I can’t remember."
In the Generic List Object’s speech recognition window, you may separate phrases just as you would with the Generic Object. (I.e. using a <return>) You may combine both words and variables in the recognition window
Details
- The variable $answer should be a string.
- Within the variable $answer, separate word groups using a comma (,)
This is equivalent to separating words with a <return> in a recognition port.
For example if the value of answer is
then the recognizer will spot any one of the words individually.
For example the value of answer is
Specifying an exact pronunciation using phonemes
The Speech Toolkit uses the WorldBet symbols Rather than the International Phonetic Alphabet for phonetic representation. One reason is that the IPA has many characters that interfere with Tcl/TK and are not represented on standard keyboards. To help those familiar with IPA, there is an
IPA / WorldBet translator.
To insert phonemes into the recognizer using the IPA Keypad translator:
- Right Click the IPA symbols for an audio example ( or use audio button )
- Double Click the IPA symbols to insert the associated WorldBet phoneme in the Recognition Box ( or use insert button )
- Hold the mouse over the IPA symbol to view a brief Sticky Note description
Type and Category
Type: Because the Generic List Object allows speech recognition on both words and phonemes, you must tell the system which one you are using. The default setting is
Category:
The Speech Toolkit has an optional "Data Capture Mode" (see Data Capture in the reference manual for details). The Data file is simply a tab delimited text file where each line represents information from an object during the dialog. Each Generic, Generic List Object, and PSL Response Object make an entry into the data capture file during a dialog. The Category menu allows you to classify a user’s responses in the recognition port as either Pass, Trap, Help, Other or the default Undefined.
Pass: Use this setting to categorize the user’s response as "correct" or "expected"
Trap: Used with *any in the recognition port. The user’s response is incorrect or unexpected
Help: User says, "help" or requests assistance in the dialog
Other: Reserved for your own classification
Undefined: Category not specified
Each object’s preferences window has a subset of these tabs.
