Voice activated control apparatus
First Claim
1. A voice activated control apparatus for control of at least one variable of a system, comprising:
- drive means responsive to electrical signals for creating controlled changes of the at least one variable;
sound detection means for converting acoustic energy into audio-electrical signals;
control means including;
word recognition means for recognizing commands from said audio-electrical signals and for generating corresponding identified electrical signals;
means for generating operating electrical signals corresponding to said identified electrical signals;
output signal generator means, responsive to said operating electrical signals for delivering actuating electrical signals to said drive means;
means for measuring the value of the at least one variable;
memory means for recording the value of the at least one variable at an identified instant in response to a command applied to said sound detection means indicating that the value at the identified instant should be recorded, said memory means also recording a value identifying command applied to said sound detection means and corresponding to the value of the at least one variable at the said identified instant; and
means for restoring the at least one variable to the value of the at least one variable at said identified instant upon application of said value identifying command to said sound detection means.

Abstract
A system is provided with a voice activated control apparatus which permits precise control of one or more system variables by means of voice commands uttered by the system operator. When a system variable is in a movement or change mode, the movement or change is terminated by any sound exceeding a preestablished acoustic threshold level. Any value of one or more system variables can be identified and appropriate data stored in a memory to permit the one or more system variables to return to an identified value or state with a single voice command. The control apparatus is combined with a screen monitor and/or an acoustic speaker to provide visible and/or acoustic responses to an operator. The control apparatus is practical for retrofitting existing remotely controllable systems.

11. A voice activated control apparatus for control of at least one variable of a system, comprising:
-
drive means responsive to electrical signals for creating controlled changes of the at least one variable; sound detection means for converting acoustic energy into audio-electrical signals; control means including; word recognition means for identifying commands from said audio-electrical signals and for generating corresponding identified electrical signals; means for generating operating electrical signals corresponding to said identified electrical signals; output signal generator means, responsive to said operating electrical signals for delivering actuating electrical signals to said drive means, whereby word commands corresponding to said commands, applied to said sound detection means will result in preestablished controlled changes of the at least one variable; and stop means for stopping any change of the at least one variable when any audio-electrical signal is delivered to said control means having an amplitude which exceeds a preestablished threshold amplitude while said variable is in a state of change, said variable remaining unchanged until another audio-electrical signal corresponding to one of said word commands is applied to said sound detection means. - View Dependent Claims (12, 13, 14, 15, 16, 17)
