Abstract

A terminal and speech-recognized text edit method edit the text input through writing recognition or speech recognition function efficiently. The text edit method includes displaying at least one letter input through speech recognition; detecting one of touch and speech inputs; analyzing the detected input; and performing a certain operation corresponding to the at least one letter based on the analysis result. The terminal and speech-recognized text edit method are advantageous in editing misrecognized speech-input text efficiently though finger or pen gesture-based or speech recognition-based input.

Claims

1. A method for editing text, the method comprising:

displaying at least one letter input using speech recognition;

detecting one of a touch input or a speech input;

analyzing the detected input; and

performing an operation corresponding to the at least one letter based on a result of the analyzing.

2. The method of claim 1, wherein analyzing comprises:

identifying, in response to detection of a touch input, a type of the touch input based on a presence of at least one of a touch position, a drag occurrence, a shape, a text inclusion, a duration, an auxiliary key activation, or consecutive touches; and

performing, in response to detection of a speech input, speech recognition on the speech input.

3. The method of claim 2, wherein the operation is set depending on whether an auxiliary key is activated.

4. The method of claim 1, wherein performing the operation comprises:

detecting one of an additional touch input or an additional speech input in response to performing the operation;

analyzing the additionally detected input; and

performing an additional operation corresponding to the at least one letter based on a result of analyzing the additionally detected input.

5. The method of claim 1, wherein the operation is one of an input, a delete, a crop, a transpose, a conversion, and a save.

6. The method of claim 1, wherein performing the operation comprises determining, when the touch input is a special symbol, a sentence type among a declarative sentence, interrogative sentence, and an exclamatory sentence based on the special symbol.

7. The method of claim 1, wherein performing the operation comprises controlling a function in response to the detected input.

8. The method of claim 7, wherein the function is one of Natural Language Processing (NLP), placing a call, sending a text message, saving a memo, an information search, or multimedia playback.

9. The method of claim 1, wherein performing the operation comprises displaying a submenu including at least one of a text edit, a substitute letter list, and font change items.

10. A terminal comprising:

a display unit configured to display at least one letter input using speech recognition;

a touch input unit configured to detect a touch input;

a speech input unit configured to detect a speech input; and

a control unit configured to detect one of the touch input and the speech input, analyze the detected input, and perform an operation corresponding to the at least one letter based on a result of analyzing the detected input.

11. The terminal of claim 10, wherein the control unit is configured to identify, in response to detection of a touch input, a type of the touch based on a presence of at least one of a touch position, a drag occurrence, a shape, a text inclusion, a duration, an auxiliary key activation, or consecutive touches, and perform, in response to detection of a speech input, speech recognition on the speech input.

12. The terminal of claim 13, wherein the operation is set depending on whether an auxiliary key is activated.

13. The terminal of claim 10, wherein the control unit is configured to control the touch input unit and the speech input unit to detect one of an additional touch input or an additional speech input in response to the operation, analyze the additionally detected input, and perform an additional operation corresponding to the at least one letter based on a result of analyzing the additionally detected input.

14. The terminal of claim 10, wherein the operation is one of an input, a delete, a crop, a transpose, a conversion, and a save.

15. The terminal of claim 10, wherein the control unit is configured to determine, when the touch input is a special symbol, a sentence type among a declarative, sentence, interrogative sentence, and an exclamatory sentence based on the special symbol.

16. The terminal of claim 10, wherein the control unit is configured to control a function in response to the detected input.

17. The terminal of claim 10, wherein control unit is configured to control one of functions of Natural Language Processing (NLP), placing a call, sending a text message, saving a memo, an information search, or multimedia playback.

18. The terminal of claim 10, wherein the control unit is configured to control the display unit to display a submenu including at least one of a text edit, a substitute letter list, and font change items, in response to the detected input.

19. A method of editing text, the method comprising:

displaying at least one letter input through speech recognition;

determining, in response to detection of a touch input, whether the touch input is made in a state that an auxiliary key is activated; and

performing an operation based on a result of determining whether the touch input is made in the state that the auxiliary key is activated, the operation being set depending on whether the auxiliary key is activated.

20. A method of editing text, the method comprising:

displaying at least one letter input through speech recognition;

analyzing, in response to detection of a touch input, the touch input;

detecting a speech input in correspondence to a result of analyzing the touch input; and

performing an operation corresponding to the at least one letter based on the detected speech input.
