1. An interactive voice response system for a telecommunications system, comprising:
- an adjunct processor that outputs an output data stream to user;
a speech gateway enabling system comprising;
a speech recognition engine operable to identify words in an input voice stream received from the user on a first communication path extending between the user and the speech gateway enabling system and a speech gateway controller operable (a) to transfer at least a portion of the input voice stream from the first communication path to a second communication path extending between the speech gateway enabling system to the adjunct processor and (b) to transfer the at least a portion of the input voice stream from the first communication path to the speech recognition engine for processing.

Abstract
The present invention is directed to a speech enabling gateway system that can provide a speech recognition capability to signal-based adjunct processors, such as DTMF-based adjunct processors. The gateway, in one configuration, conferences two or more channels together and performs speech recognition on data streams carried by one or both of the channels. Spoken commands are mapped to appropriate signals for the signal-based adjunct processor.

7. A method of providing interactive voice response capability in a telecommunications system, comprising:
-
(a) directing to a speech recognition engine at least a portion of an input voice stream received from a user on a first communication path extending between the user and a first adjunct processor;
(b) detecting at least some of the words in the at least a portion of the input voice stream;
(c) transferring the input voice stream to a second communication path extending between the first adjunct processor and a second adjunct processor;
(d) comparing at least some of the detected words with a grammar, the grammar correlating a plurality of words with a corresponding plurality of DTMF codes, to identify corresponding DTMF codes for each of the at least some of the detected words; and
(e) transmitting a DTMF signal corresponding to at least one identified DTMF code on a second communication path extending between the first adjunct processor and the second adjunct processor. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16)

17. A system of providing interactive voice response capability in a telecommunications system, comprising:
-
first and second adjunct processors;
a speech recognition engine that detects at least some words in an input voice stream received from a user on a first communication path extending between the user and the first adjunct processor;
comparing means for comparing at least some of the detected words with a grammar, the grammar correlating a plurality of words with a corresponding plurality of DTMF codes, to identify corresponding DTMF codes for each of the at least some of the detected words;
directing means for directing to the speech recognition engine at least a portion of the input voice stream;
transferring means for transferring the input voice stream to a second communication path extending between the first adjunct processor and the second adjunct processor; and
transmitting means for transmitting a DTMF signal corresponding to at least one identified DTMF code on a second communication path extending between the first adjunct processor and the second adjunct processor. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
