Playback speed optimization
View Patent ↗An approach is provided that identifies a preferred words-per-minute corresponding to a user listening to an audio. The actual words-per-minute of a selected audio segment is determined and used to calculate a playback speed adjustment value based on the preferred words-per-minute and the actual words-per-minute. A playback speed is adjusted according to the calculated playback speed adjustment value and the audio segment is audibly played at the adjusted first playback speed.
1. A method, implemented by an information handling system comprising a processor, a memory accessible by the processor, and a network interface connecting the information handling system to a computer network, the method comprising:
identifying a preferred words-per-minute corresponding to a user, wherein the identifying further comprises:
determining a type of the audio source file; and
selecting the preferred words-per-minute based on the determined type of the audio source file;
determining a first actual words-per-minute as originally spoken and recorded in a selected first audio segment;
calculating a first playback speed adjustment value based on the preferred words-per-minute and the first actual words-per-minute;
adjusting a first playback speed according to the calculated first playback speed adjustment value; and
audibly playing the first audio segment at the adjusted first playback speed.
2. The method of claim 1 further comprising:
partitioning the audio source file into a plurality of audio segments that includes the selected audio segment.
3. The method of claim 2 further comprising:
determining a second actual words-per-minute of a second audio segment selected from the plurality of audio segments;
calculating a second playback speed adjustment value based on the preferred words-per-minute and the second actual words-per-minute;
adjusting a second playback speed according to the calculated second playback speed adjustment value, wherein the second playback speed is different than the first playback speed; and
audibly playing the second audio segment at the adjusted second playback speed.
4. The method of claim 1 further comprising:
identifying the type of the audio source file based on a source corresponding to the audio source file.
5. The method of claim 1 further comprising:
identifying the type of the audio source file based on a word analysis performed on the audio source file.
6. The method of claim 1 further comprising:
calculating the playback speed adjustment by dividing the preferred words-per-minute by the actual words-per-minute.
7. An information handling system comprising: one or more processors; an audio output accessible by at least one of the processors; a memory coupled to at least one of the processors; and a set of computer program instructions stored in the memory and executed by at least one of the processors in order to perform actions comprising: identifying a preferred words-per-minute corresponding to a user, wherein the identifying further comprises:
determining a type of the audio source file; and selecting the preferred words-per-minute based on the determined type of the audio source file; determining a first actual words-per-minute as originally spoken and recorded in a selected first audio segment;
calculating a first playback speed adjustment value based on the preferred words-per-minute and the first actual words-per-minute; adjusting a first playback speed according to the calculated first playback speed adjustment value; and audibly playing, via the audio output, the first audio segment at the adjusted first playback speed.
8. The information handling system of claim 7 wherein the actions further comprise:
partitioning the audio source file into a plurality of audio segments that includes the selected audio segment.
9. The information handling system of claim 8 wherein the actions further comprise:
determining a second actual words-per-minute of a second audio segment selected from the plurality of audio segments;
calculating a second playback speed adjustment value based on the preferred words-per-minute and the second actual words-per-minute;
adjusting a second playback speed according to the calculated second playback speed adjustment value, wherein the second playback speed is different than the first playback speed; and
audibly playing the second audio segment at the adjusted second playback speed.
10. The information handling system of claim 7 wherein the actions further comprise:
identifying the type of the audio segment based on a source corresponding to the audio source file.
11. The information handling system of claim 7 wherein the actions further comprise:
identifying the type of the audio source file based on a word analysis performed on the audio source file.
12. The information handling system of claim 7 wherein the actions further comprise:
calculating the playback speed adjustment by dividing the preferred words-per-minute by the actual words-per-minute.
13. A computer program product comprising: a computer readable storage medium, comprising computer program code that, when executed by an information handling system, executes actions comprising: identifying a preferred words-per-minute corresponding to a user, wherein the identifying further comprises:
determining a type of the audio source file; and selecting the preferred words-per-minute based on the determined type of the audio source file; determining a first actual words-per-minute as originally spoken and recorded in a selected first audio segment;
calculating a first playback speed adjustment value based on the preferred words-per-minute and the first actual words-per-minute; adjusting a first playback speed according to the calculated first playback speed adjustment value; and audibly playing the first audio segment at the adjusted first playback speed.
14. The computer program product of claim 13 wherein the actions further comprise:
partitioning the audio source file into a plurality of audio segments that includes the selected audio segment.
15. The computer program product of claim 14 wherein the actions further comprise:
determining a second actual words-per-minute of a second audio segment selected from the plurality of audio segments;
calculating a second playback speed adjustment value based on the preferred words-per-minute and the second actual words-per-minute;
adjusting a second playback speed according to the calculated second playback speed adjustment value, wherein the second playback speed is different than the first playback speed; and
audibly playing the second audio segment at the adjusted second playback speed.
16. The computer program product of claim 13 wherein the actions further comprise:
identifying the type of the audio source file based on a source corresponding to the audio source file.
17. The computer program product of claim 13 wherein the actions further comprise:
identifying the type of the audio source file based on a word analysis performed on the audio source file.
