Abstract

A method of monitoring for security events using a speech recognition system can include receiving a sound signal within the speech recognition system and determining at least one attribute of the sound signal. The attribute of the sound signal can be compared with one or more acoustic models associated with a security event. The method can further include identifying the sound signal as a security event according to the comparing step.

Claims

1. A computer-readable storage, having stored thereon a computer program having a plurality of code sections executable by a computer for causing the computer to perform the steps of:

receiving a sound signal within the speech recognition engine;

determining at least one attribute of the sound signal;

comparing the attribute of the sound signal with at least one acoustic model associated with the security event;

notifying a user over a specified communications channel if, based upon comparison of the attribute of the sound signal with at least one acoustic model, the sound signal is identified as the security event;

initiating a recording of an audio loop for a predetermined time frame to record other sounds signals if, based upon comparison of the attribute of the sound signal with at least one acoustic model, the sound signal is identified as the security event.

2. The computer-readable storage of claim 1, further comprising sending a message describing the detected security event over a specified communications channel.

3. The computer-readable storage of claim 2, further comprising sending a recording of the sound signal with the message.

4. The computer-readable storage of claim 2, wherein the communication channel is an Internet communication channel.

5. The computer-readable storage of claim 2, wherein the communication channel is at least one of a wireless communication channel and a telephony communication channel.

6. The computer-readable storage of claim 2, said sending step further comprising notifying the user of a system failure.

7. The computer-readable storage of claim 1, wherein the speech recognition engine is disposed within a personal computer.

8. The computer-readable storage of claim 1, said receiving step comprising detecting an acoustic sound through a transducer communicatively linked to the speech recognition engine.

9. The computer-readable storage of claim 1, wherein said sound signal specifies a sound of an alarm.

10. The computer-readable storage of claim 1, wherein the sound signal specifies a sound of glass breaking, a person walking, an animal noise, or a human voice.
