Some Natural Access functions have parameters that you can modify to:
Enable or disable function features.
Adapt a function for exceptional configurations.
For example, when recording speech data you can specify:
The subset of DTMF keys entered by the telephone caller that abort the function.
The gain applied to the input signal.
An initial timeout in which the caller must start speaking before the function terminates.
The amount of silence after a caller has stopped speaking before the function terminates.
The beep tone frequency, amplitude, and duration.
Automatic gain control settings.
These parameters are grouped together into structures for convenience and efficiency. Each parameter structure has a default value that is sufficient for many configurations.
