Abstract

The present invention relates to voice processing and provides a method and system for correcting a text. The method comprising: determining a target text unit to be corrected in a text; receiving a reference voice segment input by the user for the target text unit; determining a reference text unit whose pronunciation is similar to a word in the target text unit based on the reference voice segment; and correcting the word in the target text unit in the text by the reference text unit. The present invention enables the user to easily correct errors in the text vocally.

Claims

1. A system for correcting text, comprising:

a target text unit determining section configured to determine a target text unit to be corrected in the text;

a reference voice segment receiving section configured to receive a reference voice segment input by a user for the target text unit;

a reference text unit determining section configured to determine a reference text unit whose pronunciation is similar to a word in the target text unit based on the reference voice segment; and

a target text unit correcting section configured to correct the word in the target text unit in the text by the reference text unit.

2. The system according to claim 1, wherein the text is a recognized text of voice data.

3. The system according to claim 1, wherein the reference text unit determining section comprises:

a voice recognition section configured to perform voice recognition on the reference voice segment to obtain the reference text segment,

wherein the reference text unit determining section is further configured to determine the reference text unit whose pronunciation is similar to the word in the target text unit from the reference text segment.

4. The system according to claim 3, wherein the reference text unit determining section further comprises:

a phoneme parsing section configured to parse a phoneme corresponding to the reference text segment and a phoneme corresponding to the target text unit,

wherein the reference text unit determining section is further configured to determine the reference text unit whose pronunciation is similar to the word in the target text unit from the reference text segment based on phoneme similarity.

5. The system according to claim 1, wherein the reference text unit determining section comprise:

a voice recognition section configured to perform voice recognition on the reference voice segment to obtain the reference text segment,

wherein the reference text unit determining section is further configured to determine a voice sub-segment whose pronunciation is similar to the word in the target text unit from the reference voice segment based on pronunciation similarity, and obtain the reference text unit corresponding to the voice sub-segment from the reference text segment.

6. The system according to claim 1, wherein the determined reference text unit is multiple reference text units, wherein the reference text unit determining section is further configured to receive a selection by the user for one of the multiple reference text units to correct at least one word in the target text unit.

7. The system according to claim 1, wherein the determined reference text unit is multiple reference text units, wherein the target text unit correcting section is further configured to select the reference text unit for correcting the word in the target text unit based on the confidences of the multiple reference text units.

8. The system according to claim 1, further comprising a boundary recognition section configured to recognize unit boundaries of text units in the text.

9. The system according to claim 1, wherein the target text unit determining section is further configured to receive a selection by the user for text units in the text to determine the target text unit to be corrected.

10. The system according to claim 2, wherein the target text unit determining section is further configured to obtain the confidences of text units in the recognized text of the voice data, and determine the target text unit to be corrected based on the confidences.
