## Abstract

Presented are improvements for speech recognition systems used to control devices. Features include two-stage confirmation, two-stage limited speech recognition mode, and two-stage wake-up for speech driven applications and systems. A headset computer device includes such staged confirmation operation.

## Claims

### Claim 1

A method of speech control in a computer application, comprising:
given a headset computer having a microphone and a display, receiving a sound input via the microphone;
processing the sound input using a speech recognition engine coupled to the headset computer, said processing including the speech recognition engine interpreting the sound input to be a command for an action having a level of criticality that meets or exceeds a threshold level of criticality; and
in response to the processed sound input:
(i) displaying a first dialog box on the display, and
(ii) conditioning headset computer performance of the action on a user making a first confirmatory utterance corresponding to a prompt in the first dialog box.

### Claim 2 (depends on 1)

The method of claim 1, wherein the displaying of the first dialog box is able to automatically time-out.

### Claim 3 (depends on 1)

The method of claim 1, wherein the command is a command for the headset computer to disengage from a low power sleep mode.

### Claim 4 (depends on 1)

The method of claim 1, wherein the command is a command for the headset computer to disengage from a limited speech recognition mode.

### Claim 5 (depends on 1)

The method of claim 1, further comprising the steps of:
receiving via the microphone the first confirmatory utterance corresponding to the prompt in the first dialog box; and
displaying a second dialog box on the display in response to the receipt of the first confirmatory utterance, the headset computer conditioning performance of the action on the user making a secondary confirmatory utterance corresponding to a prompt in the second dialog box.

### Claim 6 (depends on 5)

The method of claim 5, wherein the displaying of the second dialog box is able to automatically time-out.

### Claim 7 (depends on 5)

The method of claim 5, wherein the command is a command for the headset computer to disengage from a low power sleep mode.

### Claim 8 (depends on 5)

The method of claim 5, wherein the command is a command for the headset computer to disengage from a limited speech recognition mode.

### Claim 9 (depends on 5)

The method of claim 5, wherein the first confirmatory utterance and the second confirmatory utterance are different from each other.

### Claim 10

A speech control apparatus comprising:
given a headset computer having a display and a microphone configured to receive a sound input;
a speech recognition engine configured to interpret the sound input and as part of that interpretation to determine whether the sound input is a command for an action having a level of criticality that meets or exceeds a threshold level of criticality, said command being a critical command; and
a processor communicatively coupled to the speech recognition engine, and in response to a determination by the speech recognition engine that a sound input is a critical command, configured to:
(i) display a first dialog box on the display, and
(ii) condition headset computer performance of the action on a user making a first confirmatory utterance corresponding to a prompt in the first dialog box.
the sound input using a speech recognition engine coupled to the headset computer, said processing including and

### Claim 11 (depends on 10)

The apparatus of claim 10, wherein the first dialog box is able to automatically time-out.

### Claim 12 (depends on 10)

The apparatus of claim 10, wherein the command is a command for the headset computer to disengage from a low power sleep mode.

### Claim 13 (depends on 10)

The apparatus of claim 10, wherein the command is a command for the headset computer to disengage from a limited speech recognition mode.

### Claim 14 (depends on 10)

The apparatus of claim 10, the processor further configured to:
receive via the microphone the first confirmatory utterance corresponding to the prompt in the first dialog box; and
display a second dialog box on the display in response to the receipt of the first confirmatory utterance, the headset computer conditioning performance of the action on the user making a secondary confirmatory utterance corresponding to a prompt in the second dialog box.

### Claim 15 (depends on 14)

The apparatus of claim 14, wherein the second dialog box is able to automatically time-out.

### Claim 16 (depends on 14)

The apparatus of claim 14, wherein the command is a command for the headset computer to disengage from a low power sleep mode.

### Claim 17 (depends on 14)

The apparatus of claim 14, wherein the command is a command for the headset computer to disengage from a limited speech recognition mode.

### Claim 18 (depends on 14)

The apparatus of claim 14, wherein the first confirmatory utterance and the second confirmatory utterance are different from each other.

### Claim 19

A headset computer comprising:
a display;
a microphone receiving sound input;
a speech recognition engine configured to interpret the sound input and as part of that interpretation to determine whether the sound input is a command for an action having a level of criticality that meets or exceeds a threshold level of criticality, said command being a critical command; and
a processor communicatively coupled to the speech recognition engine, and in response to a determination by the speech recognition engine that a sound input is a critical command, configured to:
(i) display a first dialog box on the display, and
(ii) condition headset computer performance of the action on a user making a first confirmatory utterance corresponding to a prompt in the first dialog box.

### Claim 20 (depends on 19)

The headset computer of claim 19, the processor further configured to:
receive via the microphone the first confirmatory utterance corresponding to the prompt in the first dialog box; and
display a second dialog box on the display in response to the receipt of the first confirmatory utterance, the headset computer conditioning performance of the action on the user making a secondary confirmatory utterance corresponding to a prompt in the second dialog box. ff
