Abstract

Claims (39)

1. A method of providing text responsive to detection of audio playing, including:

receiving a signal corresponding to an audio track;

determining from the signal an identity of the audio track and a current audio position within the audio track;

displaying on a display a portion of a text that is linked and synchronized to the audio track identified and automatically scrolling the portion of the text displayed in pace with the audio track playing; and

displaying a current text indicator that emphasizes current text, wherein the current text indicator is visually synchronized on the display to current audio playing from the audio track;

wherein the display is a touchscreen, further including, responsive to user interaction with the display that scrolls the current text indicator beyond an area visible on the display, displaying an updated portion of the text as the audio track continues to play and at least temporarily suspending the automatic scrolling of the portion of text displayed until the audio track catches up with the portion of the text displayed.

2. The method of claim 1 , wherein the signal corresponds to audio captured from an external source as the audio track is playing.

3. The method of claim 1 , wherein the text is lyrics and the audio track is musical.

4. The method of claim 1 , wherein the current text indicator emphasizes a stanza or paragraph of text.

5. The method of claim 1 , further including receiving a validity interval and redetermining the current audio position in the audio track upon expiration of the validity interval from an additional portion of the signal received and updating synchronization of the current text indicator with the current audio playing.

6. A non-transitory computer storage medium encoded with a computer program, the program comprising instructions that when executed by data processing apparatus cause the data processing apparatus to perform operations comprising:

receiving a signal corresponding to an audio track;

determining from the signal an identity of the audio track and a current audio position within the audio track;

displaying on a display a portion of a text that is linked and synchronized to the audio track identified and automatically scrolling the portion of the text displayed in pace with the audio track playing; and

displaying a current text indicator that emphasizes current text, wherein the current text indicator is visually synchronized on the display to current audio playing from the audio track

wherein the display is a touchscreen, further including, responsive to user interaction with the display that scrolls the current text indicator beyond an area visible on the display, displaying an updated portion of the text as the audio track continues to play and at least temporarily suspending the automatic scrolling of the portion of text displayed until the audio track catches up with the portion of the text displayed.

7. The non-transitory computer storage medium of claim 6 , wherein the signal corresponds to audio captured from an external source as the audio track is playing.

8. The non-transitory computer storage medium of claim 6 , wherein the text is lyrics and the audio track is musical.

9. The non-transitory computer storage medium of claim 6 , wherein the current text indicator emphasizes a stanza or paragraph of text.

10. The non-transitory storage medium of claim 6 , wherein the computer program instructions, when executed, further cause the data processing apparatus to perform operations comprising receiving a validity interval and redetermining the current audio position in the audio track upon expiration of the validity interval from an additional portion of the signal received and updating synchronization of the current text indicator with the current audio playing.

11. A system comprising:

one or more processors configured to perform operations comprising:

receiving a signal corresponding to an audio track;

determining from the signal an identity of the audio track and a current audio position within the audio track;

displaying on a display a portion of a text that is linked and synchronized to the audio track identified and automatically scrolling the portion of the text displayed in pace with the audio track playing; and

displaying a current text indicator that emphasizes current text, wherein the current text indicator is visually synchronized on the display to current audio playing from the audio track

wherein the display is a touchscreen, further including, responsive to user interaction with the display that scrolls the current text indicator beyond an area visible on the display, displaying an updated portion of the text as the audio track continues to play and at least temporarily suspending the automatic scrolling of the portion of text displayed until the audio track catches up with the portion of the text displayed.

12. The system of claim 11 , wherein the signal corresponds to audio captured from an external source as the audio track is playing.

13. The system of claim 11 , wherein the text is lyrics and the audio track is musical.

14. The system of claim 11 , wherein the current text indicator emphasizes a stanza or paragraph of text.

15. The system of claim 11 , wherein the processors are further configured to perform operations comprising receiving a validity interval and redetermining the current audio track upon expiration of the validity interval from an additional portion of the signal received and updating synchronization of the current text indicator with the current audio playing.

16. A method of providing text responsive to detection of audio playing, including:

receiving a signal corresponding to an audio track;

determining from the signal an identity of the audio track and a current audio position within the audio track, including a validity interval;

displaying on a display a portion of a text that is synchronized to the audio track identified and automatically scrolling the portion of the text displayed in pace with the audio track playing;

displaying a current text indicator that emphasizes current text; and

upon expiration of the validity interval, automatically redetermining the current audio position in the audio track from an additional portion of the signal received and updating synchronization of the current text indicator with the current audio playing.

17. The method of claim 16 , wherein the text is lyrics and the audio track is musical.

18. The method of claim 16 , wherein the current text indicator emphasizes a stanza or paragraph of text.
