Voice-activated control device for intelligent instruments
First Claim
1. A voice-activated control device for use with an intelligent instrument of the type having an external communication port to allow a user to control the operations of the intelligent instrument through voice activation;
- the voice-activated control device comprising;
(a) a communication interface for external coupling with the communication port of the intelligent instrument;
(b) a voice input unit, which is capable of picking up the user'"'"'s voice command, if any, and converting it to an analog voice signal;
(c) a voice signal conversion unit, which is capable of converting the output analog voice signal from the voice input unit into a digital voice signal;
(d) a voice recognition unit, which is capable of performing a voice recognition algorithm on the output digital voice signal from the voice signal conversion unit to thereby producing a voice key representative of the user'"'"'s voice command;
(e) a command-code database for storing a predefined set of command codes specific to the intelligent instrument; and
(f) a data acquisition unit, which is capable of searching through the command-code database to find a command code corresponding to the output voice key from the voice recognition unit, and further capable of transferring the retrieved command code via the communication interface to the intelligent instrument to cause the intelligent instrument to perform a function specific to the command code.

Abstract
A voice-activated control device is proposed for use with an intelligent instrument, such as an intelligent oscilloscope, of the type having an external communication port, such as IEEE-488 or RS-232 compliant communication port, to allow a user to control the operations of the intelligent instrument through voice activation. The proposed voice-activated control device can be either implemented as an externally-coupled module box which can be externally coupled between an intelligent instrument and a computer system, or as a soft-ware program loaded in a computer system having a compliant communication interface and a digital voice processing module. The proposed voice-activated control device allows the user to control the operations of the intelligent instrument simply by uttering a voice command, and the voice-activated control device will be automatically activated to send out the corresponding command code via the IEEE-488 or RS-232 communication link to the intelligent instrument to cause the intelligent instrument to operate accordingly.
