dtmf-buffer-time

Specifies the size of the type-ahead buffer.

Value

Integer: 0–INT_MAX (milliseconds)

DEFAULT: 0

How to set

Shown in precedence order (see Rules of parameter precedence):

Set in the browser, using the Vendor-Specific-Parameters header in a SET-PARAMS method.

In the application's session xml in the <speechrecog> section of <speechserver> under <sessionparameters>.

Usage

Seldom used.

The type-ahead buffer collects DTMF digits as they are pressed, even when there is no RECOGNIZE command active. When the browser sends a RECOGNIZE method, the recognizer looks to this buffer to match the SET-PARAMS request. If the digits in the buffer are not sufficient, then the recognizer continues listening for more digits to match the grammar.
