1. An apparatus, comprising:
- an input that receives speech commands over a network from a station set of a subscriber, said speech commands controlling a service being provided by a service unit with at least part of the service operation being controlled by control signals sent across the network;
a speech recognition unit, coupled to said input, that converts the speech commands into control signals;
an output that transmits the control signals over a public switched telephone network to the service unit that is located remote from the speech recognition unit;
wherein the commanded service function is delivered from the service unit through the network, through the speech recognition unit and subsequently to the station set of the subscriber.

Abstract
A speech recognition system front end interface to provide a subscriber voice control over many voice mail functions. The speech recognition system converts spoken instructions into DTMF instructions for voice mail systems while allowing prompts form the voice mail system and DTMF tones from the subscriber to pass through without any interference by the speech recognition system. To accomplish these pass through functions, the speech recognition system sets up what is know as a hairpin connection between the subscriber, the speech recognition system and the voice mail system.

4. A method for controlling a voice mail system comprising the steps of:
-
a. receiving a call from a subscriber over a public telecommunication network at a system providing speech recognition services and collecting a caller ID;
b. initiating another call to a voice mail system subscribed to by the subscriber based upon the caller ID, the another call originated by the system providing speech recognition services and placed over the public telecommunication network;
c setting up a hairpin call connection between the call and the another call at said speech recognition system such that the speech recognition system listens to the subscriber; and
at the same time the subscriber listens to the voice mail system;
d. said speech recognition system converting speech commands received from the subscriber into control signals;
e transmitting the control signals over a public switched telephone network to the voice mail system that is located remote from the speech recognition system. - View Dependent Claims (5, 6)

7. A method for providing a speech recognition interface for a voice mail system comprising the steps of:
-
receiving a call at a speech recognition system speech commands from a subscriber transmitted over a telecommunication network;
translating the speech commands at the speech recognition system into control signals adapted for controlling the voice mail system;
originating another call from the speech recognition system to the voice mail system over the telecommunication network transmitting from the speech recognition system the control signals via the another call over the telecommunication network to the voice mail system. - View Dependent Claims (8, 9, 10, 11)
