Abstract

Occurrences of at least one of a plurality of telephone number-related speech patterns are identified in an audio stream using speech analysis techniques. At least one number pattern corresponding to the occurrences are thereafter identified and stored for later presentation to a user of a mobile device. The occurrences and corresponding number pattern(s) may be filtered to reduce the likelihood of false detections. Furthermore, the detected number pattern(s) may be augmented to ensure completeness. Users may edit and persistently store the resulting number pattern(s). In one embodiment, a portion of the audio stream may be stored and subsequently subjected to the speech analysis process. The stored portion of the audio stream may be reproduced at substantially the same time that at least one number pattern detected therein is provided to the user. In this manner, telephone numbers in audio streams may be captured safely and conveniently.

Claims

1. In a communication device, a method for processing a telephone number within an audio stream, the method comprising:

identifying occurrences of at least one of a plurality of telephone number-related speech patterns in the audio stream;

storing at least one detected number pattern corresponding to the occurrences of the at least one of the plurality of telephone number-related speech patterns; and

presenting the at least one detected number pattern to a user of the communication device.

2. The method of claim 1, the audio stream comprising a wirelessly received audio stream.

3. The method of claim 1, further comprising:

providing an augmented number pattern by appending at least one additional number pattern to the at least one detected number pattern; and

presenting the augmented number pattern to the user.

4. The method of claim 3, further comprising:

determining the at least one additional number pattern based on at least one of;

a portion of the detected number pattern, a length of the detected number pattern, a location of operation of the communication device and an area of registration of the communication device.

5. The method of claim 1, further comprising:

disregarding occurrences of pause-filler utterances within the audio stream between any two of the occurrences.

6. The method of claim 1, further comprising:

identifying occurrence of a keyword utterance within the audio stream proximate in time to the occurrences of the at least one of the plurality of telephone number-related speech patterns; and

storing the at least one detected number pattern corresponding to the occurrences of the at least one of the plurality of telephone number-related speech patterns when the occurrences of the at least one of the plurality of telephone number-related speech patterns are proximate in time to the occurrence of the keyword utterance.

7. The method of claim 1, further comprising:

rendering the audio stream audible to the user;

providing a stored portion of the audio stream in response to receiving an instruction from the user; and

identifying occurrences of at least one of a plurality of telephone number-related speech patterns in the stored portion of the audio stream.

8. The method of claim 7, further comprising:

presenting the stored portion of the audio stream substantially simultaneously with the detected number pattern.

9. The method of claim 1, further comprising:

persistently storing the detected number pattern in response to receiving an instruction from the user.

10. The method of claim 1, further comprising:

providing an edited number pattern in response to edits to the at least one detected number pattern received from the user; and

persistently storing the edited number pattern in response to the instruction.

11. A wireless communication device comprising:

a processor;

a display coupled to the processor;

a storage device coupled to the processor; and

processor executable instructions stored in the storage device,

the processor executable instructions including a speech analysis segment that identifies occurrences of at least one of a plurality of telephone number-related speech patterns in the audio stream,

the processor executable instructions including a detected number pattern storage segment that stores at least one detected number pattern corresponding to the occurrences of the at least one of the plurality of telephone number-related speech patterns,

the processor executable instructions including a detected number pattern presentation segment presenting the at least one detected number pattern via the display.

12. The wireless communication device of claim 11, further comprising:

a wireless receiver, coupled to the processor,

the processor executable instructions including an audio stream receiving segment whereby the audio stream is received via the wireless receiver.

13. The wireless communication device of claim 11,

the processor executable instructions including a number pattern augmenting segment that appends at least one additional number pattern to the at least one detected number pattern,

whereby the detected number pattern presentation segment present an augmented number pattern provided by the number pattern augmenting segment.

14. The wireless communication device of claim 11,

the processor executable instructions including a keyword utterance detection segment that identifies occurrences of a keyword utterance,

whereby the detected number pattern storage segment stores the at least one detected number pattern corresponding to the occurrences of the at least one of the plurality of telephone number-related speech patterns when the occurrences of the at least one of the plurality of telephone number-related speech patterns are proximate in time to the occurrence of the keyword utterance.

15. The wireless communication device of claim 11, further comprising:

a user-actuated instruction input device coupled to the processor,

the processor executable instructions including an audio stream capture segment responsive to an instruction from the user-actuated instruction input device,

whereby the speech analysis segment operates upon a stored audio stream portion provided by the audio stream capture segment.

16. The wireless communication device of claim 15, further comprising:

a speaker, coupled to the processor,

the processor executable instructions including a stored audio stream portion presentation segment,

the detected number presentation segment presenting the at least one detected number pattern via the display substantially simultaneously with the stored audio stream presentation segment presenting the stored audio stream portion via the speaker.

17. A wireless communication device comprising:

an audio stream receiving wireless receiver;

a telephone number-related speech pattern recognizing speech analyzer coupled to the audio stream receiving wireless receiver and operating upon an audio stream provided by the audio stream receiving wireless receiver;

a detected number pattern filtering component coupled to the telephone number-related speech pattern recognizing speech analyzer operating upon at least one detected number pattern provided by the telephone number-related speech pattern recognizing speech analyzer; and

a filtered number pattern augmenting component coupled to the detected number pattern filtering component.

18. The wireless communication device of claim 17, the detected number pattern filtering component further comprising at least one pattern rule.
