Hands-free, voice-operated remote control transmitter
First Claim
1. A speech recognition control system for controlling appliances, the control system comprising:
- a microphone for receiving audio signals;
a speech recognition system for receiving audio signals from said microphone and converting said audio signals to control signals for controlling a selected appliance, the speech recognition system having a speech recognition mode for decoding said audio signals and generating control signals for controlling an appliance and a MUTE mode for the selected appliance in order to reduce background noise;
wherein said MUTE mode includes a plurality of submodes; and
wherein one of said submodes is a recognition error muting mode for automatically muting an appliance upon detection of one or more types of recognition errors.

Abstract
A wireless, programmable, sound-activated and voice-operated remote control transmitter can be used to add hands-free speech control operation to a plurality of remotely controlled appliances manufactured by various manufacturers, each of which is normally controlled with one or more signals from an associated remote control transmitter. The present invention may be pre-programmed with a universal library of codes for controlling various appliance categories and appliances produced by various manufacturers within each category. The present invention may also be programmed using the controlled appliances'"'"' remote control transmitters and one or more operators'"'"' spoken commands. Once programming is complete, there is no need for the operator to manually operate the present invention, allowing true hands-free voice control of the remotely controlled products. The programmable transmitter structure includes means for independently aligning the output signal transmitter and voice input microphone with the remotely controlled appliance and the operator, respectively. Voice commands are organized into a plurality of linked recognition vocabulary sets, each representing a subset of the complete voice command vocabulary available. These subsets are structured in a fashion that is intuitive to the user because the structure is consistent with controlled appliance operation. The invention discloses a scheme by which a user can easily navigate via voice commands between recognition sets to attain access to the intended voice commands.
