1. A method for controlling a plurality of consumer electronic target devices interconnected via a digital bus to a central authority device, said central authority performing the steps of:
- receiving a speech command from a user;
evaluating said received speech command to determine whether one of said target devices is identified;
issuing, in response to said identified target device, a corresponding command from said central authority to said target device;
evaluating said received speech command to determine whether said received speech command is unique to a specific target device;
issuing, in response to said unique received speech command, a corresponding command from said central device to said specific target device; and
thereaftergenerating, in response to said speech command not identifying said target device and not being unique to one of said target devices, a list of target devices capable of being controlled by said received speech command.

Abstract
A speech based man-machine communication system is given, comprising more than one controllable device provided with speech synthesis function. Each of the devices in question is provided with its own unique voice pattern. The devices are connected via a bus, so that a central authority handles all the requests from the user. Because the user uses his natural language, commands can be ambiguous. Therefore an algorithm for handling ambiguous situations is provided.
