Abstract

A method and apparatus of detecting and reporting an emergency situation of a mobile terminal user to a third party using an audio recognition function included in a mobile terminal are provided. The method includes recognizing speech received from a microphone; determining whether a current situation is emergent based on the recognized speech; and controlling a radio frequency communication unit to report the emergency situation to a preset external device when the current situation is emergent.

Claims

1. A method operative in a mobile terminal having a speech recognition function, the method comprising:

recognizing speech received from a microphone;

determining whether a current situation is emergent based on the recognized speech; and

reporting an emergency situation via a radio frequency communication unit to a preset external device when the current situation is determined to be emergent.

2. The method of claim 1, wherein reporting the emergency situation comprises:

recording the speech received from the microphone; and

transmitting the recorded speech to the external device.

3. The method of claim 2, wherein the recording of the speech comprises recording the speech for a preset duration of time.

4. The method of claim 1, wherein reporting the emergency comprises transmitting a call connection signal for a call to the external device.

5. The method of claim 1, wherein the determining whether the current situation is emergent comprises:

comparing speech characteristic information in the recognized speech with stored emergency situation pattern information; and

determining that a current situation is emergent when the speech characteristic information in the recognition information is different from the stored emergency situation pattern information, wherein the different speech characteristic information is indicative of a non-registered person.

6. The method of claim 1, comprising:

comparing text information in the recognition information with stored emergency situation pattern information; and

determining that the current situation is emergent when the text information in the recognition information is substantially the same as the stored emergency situation pattern information.

7. The method of claim 1, further comprising determining that the current situation is emergent when a magnitude of the recognized speech is equal to or greater than a preset magnitude.

8. The method of claim 1, further comprising detecting input information for activating an emergency situation alert service,

wherein determining whether the current situation is emergent is performed in response to detection of the input information.

9. The method of claim 1, wherein determining whether the current situation is emergent is automatically performed when a preset time arrives.

10. A mobile terminal comprising:

a microphone;

an audio processor converting speech input from the microphone into speech data;

a radio frequency communication unit transmitting information associated with the speech data to an external device; and

a controller recognizing the speech data from the audio processor, determining whether a current situation is emergent based on the speech recognition, and controlling the radio frequency unit to report an emergency situation to the external device when the current situation is determined to be emergent.

11. The mobile terminal of claim 10, wherein when the current situation is emergent, the controller records the speech data from the audio processor, and controls the radio frequency communication unit to transmit the recorded speech data to the external device.

12. The mobile terminal of claim 10, wherein when the current situation is emergent, the controller controls the radio frequency communication unit to transmit a call connection signal for a call with the external device.

13. The mobile terminal of claim 11, wherein when the current situation is emergent, the controller controls the radio frequency communication unit to transmit a call connection signal for a call with the external device while the speech data is being recorded.

14. The mobile terminal of claim 10, wherein the controller compares speech characteristic information in the recognition information with a stored emergency pattern information, and determines a current state as an emergency situation when the speech characteristic information in the recognition information is different from the stored emergency pattern information, wherein the different speech characteristic information is indicative of the presence of a non-registered person.

15. The mobile terminal of claim 10, wherein the controller compares text information in the recognition with stored emergency situation pattern information, and determines a current situation as an emergency situation when the text information in the recognition is the same as the stored emergency situation pattern information.

16. The mobile terminal of claim 10, wherein when magnitude of a speech in the recognition information equals or exceeds a preset magnitude, the controller determines the current situation as the emergency situation.
