## Abstract

A computer-implemented method executes voice commands issued from within a command boundary. The method includes defining a command boundary for a VCD, where the command boundary is based on receiving an input from a user. The method further includes receiving, from the user and by the VCD, a voice command. The method also includes determining an origination location of the voice command. The method includes classifying the voice command into a command category. The method further includes executing the voice command in response to determining the origination location is within the command boundary for the VCD. The method also includes storing a set of data for the voice command.

## Claims

### Claim 1

A computer-implemented method comprising:
receiving an input from a user;
defining a command boundary for a voice controlled device (VCD), wherein the command boundary is based on the receiving the input from the user, and the command boundary outlines a physical area;
receiving, from the user by the VCD and in response to the defining the command boundary, a voice command, wherein the receiving the voice command is in response to the defining the command boundary;
determining an origination location of the voice command;
determining the origination location of the voice command is within the command boundary;
classifying the voice command into a command category;
executing the voice command in response to the determining the origination location is within the command boundary for the VCD; and
storing a set of data for the voice command.

### Claim 2 (depends on 1)

The method of claim 1, wherein the command boundary is a first command boundary, the method further comprising:
defining a second command boundary for the VCD, wherein the first command boundary is associated with a first command category, and the second command boundary is associated with a second command category.

### Claim 3 (depends on 2)

The method of claim 2, wherein the executing the voice command is in response to the command category being the same as the first command category.

### Claim 4 (depends on 2)

The method of claim 2, wherein the first command boundary and the second command boundary do not overlap.

### Claim 5 (depends on 2)

The method of claim 2, wherein the first command boundary and the second command boundary at least partially overlap.

### Claim 6 (depends on 2)

The method of claim 2, wherein the first command boundary is associated with the user, and the second command boundary is associated with a second user.

### Claim 7 (depends on 1)

The method of claim 1 further comprising:
training a learning model, by a set of training data, to generate a recommendation for first command boundary, wherein the defining the first command boundary is in response to the generating of the recommendation.

### Claim 8 (depends on 7)

The method of claim 7, further comprising updating, in response to receiving feedback from the user, the learning model.

### Claim 9 (depends on 1)

The method of claim 1, wherein the command boundary is configured to deactivate in response to a trigger.

### Claim 10 (depends on 9)

The method of claim 9, wherein the trigger is includes executing a predetermined number of commands from the first command boundary.

### Claim 11 (depends on 9)

The method of claim 9, wherein the trigger is based on a period of time.

### Claim 12 (depends on 1)

The method of claim 1, wherein the input from the user is received from a virtual device.

### Claim 13 (depends on 12)

The method of claim 12, wherein the input is based on a user-drawn boundary on an interface of the virtual device.

### Claim 14 (depends on 12)

The method of claim 12, wherein the voice command is a second voice command and the origination location is a second origination location, the method further comprising:
receiving, from the user, a first voice command;
determining a first origination location of the first voice command;
determining the first origination location is outside of the command boundary;
prompting, in response to determining the first origination location is outside the command area, the user to move into the command area; and
receiving, from the user, the second voice command.

### Claim 15 (depends on 14)

The method of claim 14, wherein the prompting includes displaying, on the virtual device, the command boundary.

### Claim 16

A system comprising:
a processor; and
a computer-readable storage medium communicatively coupled to the processor and storing program instructions which, when executed by the processor, are configured to cause the processor to:
define a first command boundary for a first voice controlled device (VCD), wherein the first command boundary is based on receiving an input from a user, and the command boundary outlines a physical area;
receive, from the user by the first VCD and in response to the defining the command boundary, a voice command;
determine an origination location of the voice command;
determine the origination location of the voice command is within the command boundary;
classify the voice command into a command category;
determine the origination location is within the first command boundary;
execute, by the first VCD and in response to the determination the origination location is within the first command boundary, the voice command; and
store a set of data for the voice command.

### Claim 17 (depends on 16)

The system of claim 16, and the program instructions are further configured to cause the processor to:
define a second command boundary for a second VCD;
receive, from the user and by the second VCD, the voice command;
determine the origination location is outside the second command boundary; and
deny, by the second VCD and in response to the determination the origination location is outside the second command boundary, execution of the voice command.

### Claim 18 (depends on 17)

The system of claim 17, wherein the user is a first user, the first command boundary is correlated to the first user, the defining of the second command boundary is based on receiving an input from a second user, and the second command boundary is correlated to the second user.

### Claim 19

A computer program product, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processing unit to cause the processing unit to:
define a first command boundary for a first voice controlled device (VCD), wherein the first command boundary is based on receiving an input from a user, and the command boundary outlines a physical area;
receive, from the user by the first VCD and in response to the defining the command boundary, a voice command;
determine an origination location of the voice command;
determine the origination location of the voice command is within the command boundary;
classify the voice command into a command category;
execute the voice command in response to determining the origination location is within the command boundary for the VCD; and
store a set of data for the voice command.

### Claim 20 (depends on 19)

The computer program product of claim 19, wherein the program instructions are further configured to cause the processing unit to:
define a second command boundary for a second VCD;
receive, from the user and by the second VCD, the voice command;
determine the origination location is outside the second command boundary; and
deny, by the second VCD and in response to the determination the origination location is outside the second command boundary, execution of the voice command.
