Abstract:
1. A device control device for controlling a plurality of devices, each being controlled by use of numerical parameters, the device control device comprising: constant storage means that stores in advance a phrase and a predetermined constant in association with each other; speech recognition means that acquires speech data representing a speech, and performs speech recognition on said speech data, thereby specifying a candidate for a phrase included by said speech and computes a likelihood for each specified candidate; and device control means that specifies those devices which are controllable of said plurality of devices, and an amount of change of said numerical parameter based on the predetermined constant associated with the specified phrase and the likelihood that have been computed by said speech recognition means, and changes the numerical parameter by the specified amount of change to thereby control the specified devices, wherein said device control means controls a device when a number of said specified devices is one, and when there are a plurality of devices specified, said speech recognition means further acquires speech data to specify a candidate for the phrase and computes the likelihood, and said device control means specifies any one of the devices that are controllable, based on the predetermined constant associated with the specified phrase and likelihood computed by said speech recognition means, and controls said specified device.
