Abstract

Embodiments of the present invention address deficiencies of the art in respect to podcasting and provide a method, system and computer program product for speed podcasting. In an embodiment of the invention, a speed podcasting method can include speech recognizing an audio portion of a podcast, parsing the speech recognized audio portion to identify essential words, and playing back only audio segments and corresponding video segments of the podcast including the essential words while excluding from playback audio segments and corresponding video segments of the podcast including non-essential words.

Claims

1. A speed podcasting method comprising:

speech recognizing an audio portion of a podcast;

parsing the speech recognized audio portion to identify essential words; and

,

playing back only audio segments and corresponding video segments of the podcast including the essential words while excluding from playback audio segments and corresponding video segments of the podcast including non-essential words.

2. The method of claim 1, wherein playing back only audio segments and corresponding video segments of the podcast including the essential words while excluding from playback audio segments and corresponding video segments of the podcast including non-essential words, comprises:

matching words in the speech recognized audio portion to essential words in a data store of essential words;

determining audio segments of the audio portion including the matched words; and

,

playing back the determined audio segments while excluding other audio segments of the audio portion from playback.

3. The method of claim 1, wherein playing back only audio segments and corresponding video segments of the podcast including the essential words while excluding from playback audio segments and corresponding video segments of the podcast including non-essential words, comprises:

identifying non-essential words in the speech recognized audio portion; and

,

excluding audio segments of the audio portion from playback including the identified non-essential words while playing back other audio segments of the audio portion.

4. The method of claim 2, further comprising:

consulting a thesaurus to retrieve words synonymous with the matched words; and

,

adding the synonymous words to the data store of essential words.

5. The method of claim 2, wherein playing back the determined audio segments while excluding other audio segments of the audio portion from playback comprises:

applying a rating to each word in the data store of essential words;

associating a playback speed with each rating;

excluding from the determined audio segments audio segments with essential words associated with a rating inconsistent with a contemporaneously selected playback speed; and

,

playing back only the determined audio segments while excluding other audio segments of the audio portion from playback.

6. A mobile video playback device comprising:

an operating system configured to playback podcasts stored in the mobile video playback device;

a datastore of essential words;

a speech recognition engine; and

,

speed podcasting logic executing under management of the operating system comprising program code enabled to speech recognize an audio portion of a selected podcast, to parse the speech recognized audio portion to identify words present in the datastore of essential words, and to play back only audio segments and corresponding video segments of the podcast including the matched words while excluding from playback audio segments and corresponding video segments of the podcast including non-essential words.

7. The device of claim 6, wherein non-essential words comprise articles and pronouns.

8. The device of claim 6, further comprising a thesaurus, the program code being further enabled to locate in the thesaurus words synonymous with the identified words present in the datastore of essential words and to add the synonymous words to the datastore of essential words.

9. A computer program product comprising a computer usable medium embodying computer usable program code for, the computer program product comprising:

computer usable program code for speech recognizing an audio portion of a podcast;

computer usable program code for parsing the speech recognized audio portion to identify essential words; and

,

computer usable program code for playing back only audio segments and corresponding video segments of the podcast including the essential words while excluding from playback audio segments and corresponding video segments of the podcast including non-essential words.

10. The computer program product of claim 9, wherein the computer usable program code for playing back only audio segments and corresponding video segments of the podcast including the essential words while excluding from playback audio segments and corresponding video segments of the podcast including non-essential words, comprises:

computer usable program code for matching words in the speech recognized audio portion to essential words in a data store of essential words;

computer usable program code for determining audio segments of the audio portion including the matched words; and

,

computer usable program code for playing back the determined audio segments while excluding other audio segments of the audio portion from playback.

11. The computer program product of claim 9, wherein the computer usable program code for playing back only audio segments and corresponding video segments of the podcast including the essential words while excluding from playback audio segments and corresponding video segments of the podcast including non-essential words, comprises:

computer usable program code for identifying non-essential words in the speech recognized audio portion; and

,

computer usable program code for excluding audio segments of the audio portion from playback including the identified non-essential words while playing back other audio segments of the audio portion.

12. The computer program product of claim 10, further comprising:

computer usable program code for consulting a thesaurus to retrieve words synonymous with the matched words; and

,

computer usable program code for adding the synonymous words to the data store of essential words.

13. The computer program product of claim 10, wherein the computer usable program code for playing back the determined audio segments while excluding other audio segments of the audio portion from playback comprises:

computer usable program code for applying a rating to each word in the data store of essential words;

computer usable program code for associating a playback speed with each rating;

computer usable program code for excluding from the determined audio segments audio segments with essential words associated with a rating inconsistent with a contemporaneously selected playback speed; and

,

computer usable program code for playing back only the determined audio segments while excluding other audio segments of the audio portion from playback.
