Announcement plus speech recognition
Task
The Announcement plus speech recognition element recognizes spoken words
and stores them in a variable. For speech recognition you can also use variables
(<:variablename:>) in the Allowed terms field. A variable (<:variablename:>)
can contain several words to be recognized, separated by semicolons (today;
tomorrow; day after tomorrow).
If a text does not match the allowed words or if the maximum speech time is
over, it is distributed to the Error-exit connector.
Announcement plus speech recognition elements can have several input
connectors.
You can use any number of Announcement plus speech recognition elements.
Allowed terms
When you enter the keyword DTMF in the Allowed terms field, telephone
keystrokes are also recognized and stored in the Result variable field. The
result variable must be evaluated to check which key was pressed. Note that
DTMF digits are stored as digits (e.g., 1) in the Result variable, whereas spoken
words are stored as words (e.g., one).
You can also link a grammar file of your choice via the Allowed terms field. To
do so, you must create a local variable as usual and enter the name of the
grammar file as the value (e.g., saydigits.grxml). For further information please
refer to Tips and Tricks - Grammar for speech recognition.
Which announcement files are possible?
The announcement can be available as announcement file to be played or as text
or a text file to be read with TTS. The text or text file can also contain variables
(<:variablename:>) You can also enter several files separated by semicolons
(announcement1.wav; announcement2.wav; announcement3.wav)

directly. The variable can be a variable or a tag. The length of
the text is not limited. All characters are allowed.
