Default Value: 0.5
Set the sensitivity level. A value of 1.0 means that it is highly sensitive to quiet input. A value of 0.0 means it is least sensitive to noise. The value is a Real Number Designation.
<?xml version="1.0"?> <vxml version="2.0"> <property name="sensitivity" value="0.3"/> <form> <field type="boolean"> <prompt> Please say yes or no. </prompt> </field> </form> </vxml>
From this example, a user is able to say “yes” or “no” in a noisy environment. Setting the “sensitivity” level to a low setting helps in environments where there is alot of background noise. However, by setting the “sensitivty” to a low setting, there is also a small risk of the application missing some of the incoming speech.
