Abstract

A speech to text conversion and annotation system. In an embodiment, the system displays an annotated text corresponding to computer rendered speech and allows a user to adjust voicing and pronunciation parameters of the annotated text; and use a text to speech engine to render the annotated text to a human like generated voice that has modified voicing and pronunciation corresponding to the user selected voicing and pronunciation parameters. In another embodiment, a read-aloud coaching system is introduced that allows a student to “incrementally program” a voice synthesis engine, thoughtfully and purposively creating his or her own reading of a literary text.

Claims

1. An article comprising a medium storing software that causes a processor-based computer system to perform the following steps:

a. display an annotated text corresponding to computer rendered speech;

b. allow a user to adjust voicing and pronunciation parameters of the annotated text; and

c. use a text to speech engine to render the annotated text to a human like generated voice that has modified voicing and pronunciation corresponding to the user selected voicing and pronunciation parameters.

2. The article of claim 1 further comprising the step of allowing the user to input the text using a speech to text recognition engine.

3. The article of claim 1 further comprising the step of allowing the user to input the text using a speech to text recognition engine that also detects the users voicing and pronunciation to supply baseline parameters of the annotated text.

4. The article of claim 1 further comprising the step of allowing the user to input the text using a keyboard input like used in common text editors.

5. The article of claim 1 wherein the step of allowing the user to input voicing and pronunciation for the annotated text includes pitch, volume and timing.

6. The article of claim 1 wherein the computer system is part of an automated phone answering system.

7. The article of claim 1 wherein the user may annotate text that is the computer systems output so that the output of the computer in the form of auditory voice speech can be modified by the user.

8. A portable computing device, comprising:

a. a processor;

b. a memory coupled to the processor; and

c. a storage medium coupled to the processor including a software program that, upon execution;

i. displays an annotated text corresponding to computer rendered speech;

ii. allows a user to adjust voicing and pronunciation parameters of the annotated text; and

iii. uses a text to speech engine to render the annotated text to a human like generated voice that has modified voicing and pronunciation corresponding to the user selected voicing and pronunciation parameters.

9. The article of claim 8 further comprising the step of allowing the user to input the text using a speech to text recognition engine.

10. The article of claim 8 further comprising the step of allowing the user to input the text using a speech to text recognition engine that also detects the users voicing and pronunciation to supply baseline parameters of the annotated text.

11. The article of claim 8 further comprising the step of allowing the user to input the text using a keyboard input like used in common text editors.

12. The article of claim 8 wherein the step of allowing the user to input voicing and pronunciation for the annotated text includes pitch, volume and timing.

13. A method of teaching the auditory rendering of a literary work comprising the following steps:

a. the student generates an initial rendering of a textual literary work using a text to speech engine;

b. allowing the student to adjust voicing and pronunciation parameters of the annotated text; and

c. using a text to speech engine to render the annotated text to a human like generated voice that has modified voicing and pronunciation corresponding to the user selected voicing and pronunciation parameters.

14. The method of claim 13 further comprising the step of allowing the student user to input the text using a speech to text recognition engine.

15. The method of claim 13 further comprising the step of allowing the student user to input the text using a speech to text recognition engine that also detects the users voicing and pronunciation to supply baseline parameters of the annotated text.

16. The method of claim 13 further comprising the step of allowing the student user to input the text using a keyboard input like used in common text editors.

17. The method of claim 13 wherein the step of allowing the student user to input voicing and pronunciation for the annotated text includes pitch, volume and timing.
