Abstract

A voice dialing method and apparatus for simplifying voice dial is provided. The voice dialing method includes receiving a speech in a voice recognition mode, extracting characters from the speech, translating the characters into corresponding numerals, and dialing a phone number on the basis of the numerals.

Claims

1. A voice dialing method for a mobile phone comprising:

receiving a speech in a voice recognition mode;

extracting characters from the speech;

translating the characters into corresponding numerals; and

dialing a phone number corresponding to the numerals.

2. The voice dialing method of claim 1, further comprising converting the speech into a sequence of characters.

3. The voice dialing method of claim 1, wherein dialing a phone number comprises retrieving the phone number including the numerals from a phonebook.

4. The voice dialing method of claim 1, wherein the speech is a word or a sequence of words spoken by a user.

5. A voice dialing method for a mobile phone, comprising:

receiving a speech in a voice recognition mode;

searching for a word or phone number corresponding to the speech in a phonebook;

extracting, if the word or phone number is not retrieved, characters from the speech;

translating the characters into corresponding numerals; and

dialing a phone number corresponding to the numerals.

6. The voice dialing method of claim 5, wherein dialing a phone number comprises retrieving the phone number including the numerals from the phonebook.

7. The voice dialing method of claim 5, further comprising if a phone number is retrieved from the phonebook, dialing the phone number.

8. The voice dialing method of claim 5, wherein the speech is a word or a sequence of words spoken by a user.

9. A voice recognition-enabled mobile phone comprising:

an audio processing unit for processing a speech input through a microphone;

a memory unit for storing a phonebook, a mapping table listing characters matched with numerals, and a voice dialing application; and

a control unit for translating the speech into a sequence of numerals with reference to the mapping table and dialing a phone number on the basis of the sequence of numerals.

10. The voice recognition-enabled mobile phone of claim 9, wherein the control unit controls activation/deactivation of a voice recognition mode, character to numeral conversion, and dialing the phone number retrieved by the numeral sequence.

11. The voice recognition-enabled mobile phone of claim 10, wherein the control unit comprises:

a mode controller for selectively activating and deactivating voice dial modes according to a user request or preset configuration;

a voice recognizer for recognizing a speech and decomposing the speech into characters; and

a character translator for translating a sequence of the characters into a sequence of numerals.

12. The voice recognition-enabled mobile phone of claim 11, wherein the control unit further comprises a dialing processor for retrieving a phone number on the basis of the sequence of numerals.

13. The voice recognition-enabled mobile phone of claim 12, wherein the dialing processor retrieves a phone number including the sequence of numerals and dials the phone number in response to a user request.

14. The voice recognition-enabled mobile phone of claim 9, wherein the voice dialing application comprises:

a voice recognition module for recognizing the speech;

a voice dialing module for placing a call with the recognized speech;

a speech decomposition module for decomposing the speech into characters; and

a character-numeral translation module for translating the characters into corresponding numerals.

15. The voice recognition-enabled mobile phone of claim 9, further comprising a display unit for displaying the translated numerals.

16. The voice recognition-enabled mobile phone of claim 9, further comprising a radio frequency unit for transmitting a call request signal to a radio access network in accordance with dialing the phone number.
