The dual tone multi-frequency (DTMF) library contains a collection of preconstructed grammar rules. Each rule is designed to retrieve the numeric values associated with the DTMF pitches that are generated by a user pressing the keys of a telephone keypad. The DTMF library is a grammar resource that is used by ASP.NET Application Speech Controls.
The following table shows the rules contained in the DTMF library and descriptions of what the rules recognize.
