Abstract

A portable telephone has a for-recognition voice data storing unit for storing for-recognition voice data, a relation-to-dial information storing unit for storing pieces of dial information respectively to be used to perform a call access, a voice inputting unit for receiving a voice, a voice recognizing unit for recognizing the voice received in the voice inputting unit according to the for-recognition voice data stored in the for-recognition voice data storing unit and extracting dial information corresponding to a recognition result from the relation-to-dial information storing unit, a position detecting unit for detecting a position of the portable telephone relative to a user, and a control unit for performing a call access operation using the dial information extracted in the voice recognizing unit according to position information which is relative to the user and is detected in the position detecting unit. Accordingly, a call access processing adapted to use conditions of the user can be performed.

Claims

1. A portable telephone, comprising:

a for-recognition voice data storing unit for storing for-recognition voice data;

a relation-to-dial information storing unit for storing pieces of dial information respectively to be used to perform a call access;

a voice inputting unit for receiving a voice signal;

a voice recognizing unit for recognizing the voice signal received in the voice inputting unit according to the for-recognition voice data stored in the for-recognition voice data storing unit and extracting dial information corresponding to a recognition result from the relation-to-dial information storing unit;

a position detecting unit for detecting a position of the portable telephone relative to a user; and

a control unit for performing a call access operation according to position information, which is relative to the user and is detected in the position detecting unit, by using the dial information extracted in the voice recognizing unit.

2. A portable telephone according to

claim 1

in which the position of the portable telephone relative to the user is detected in the position detecting unit by detecting whether or not the portable telephone is in proximity to an ear of the user.

3. A portable telephone according to

claim 2

in which the call access operation using the dial information extracted in the voice recognizing unit is performed in the control unit in cases where it is detected in the position detecting unit that the portable telephone is in proximity to the ear of the user, and the call access operation using the dial information extracted in the voice recognizing unit is performed in the control unit after the reception of a call access request of the user in cases where it is detected in the position detecting unit that the portable telephone is not in proximity to the ear of the user.

4. A portable telephone according to

claim 1

, further comprising:

an external voice input/output apparatus detecting unit for detecting whether or not an external voice input/output apparatus is connected with the portable telephone, wherein the call access operation using the dial information extracted in the voice recognizing unit is performed in the control unit according to both the position information, which is relative to the user and is detected in the position detecting unit and information which is detected in the external voice input/output apparatus detecting unit and indicates whether or not the external voice input/output apparatus is connected with the portable telephone.

5. A portable telephone according to

claim 4

in which the call access operation using the dial information extracted in the voice recognizing unit is performed in the control unit in cases where it is detected in the position detecting unit that the portable telephone is in proximity to the ear of the user, the call access operation using the dial information extracted in the voice recognizing unit is performed in the control unit in cases where it is detected in the position detecting unit that the portable telephone is not in proximity to the ear of the user and in cases where it is detected in the external voice input/output apparatus detecting unit that the external voice input/output apparatus is connected with the portable telephone, and the call access operation using the dial information extracted in the voice recognizing unit is performed in the control unit after the reception of a call access request of the user in cases where it is detected in the position detecting unit that the portable telephone is not in proximity to the ear of the user and in cases where it is detected in the external voice input/output apparatus detecting unit that the external voice input/output apparatus is not connected with the portable telephone.

6. A portable telephone, comprising:

a for-recognition voice data storing unit for storing for-recognition voice data;

a relation-to-dial information storing unit for storing pieces of dial information respectively to be used to perform a call access;

a voice inputting unit for receiving a voice signal;

a voice recognizing unit for recognizing the voice signal received in the voice inputting unit according to the for-recognition voice data stored in the for-recognition voice data storing unit and extracting dial information corresponding to a recognition result from the relation-to-dial information storing unit; and

a control unit for performing a call access operation according to information, which indicates whether or not a recognition processing is started in the voice recognizing unit in response to a key input for an automatic call access, by using the dial information extracted in the voice recognizing unit.

7. A portable telephone according to

claim 6

in which the call access operation using the dial information extracted in the voice recognizing unit is performed in the control unit in cases where a recognition processing is started in the voice recognizing unit in response to a key input for an automatic call access, and the call access operation using the dial information extracted in the voice recognizing unit is performed in the control unit after the reception of a call access request of the user in cases where a recognition processing is started in the voice recognizing unit without a key input for an automatic call access.

8. A portable telephone, comprising:

a for-recognition voice data storing unit for storing for-recognition voice data;

a relation-to-dial information storing unit for storing pieces of dial information respectively to be used to perform a call access;

a voice inputting unit for receiving a voice signal;

a voice recognizing unit for recognizing the voice received in the voice inputting unit according to the for-recognition voice data stored in the for-recognition voice data storing unit, extracting dial information corresponding to a recognition result from the relation-to-dial information storing unit and comparing a parameter value obtained in a voice analysis of a recognition processing and a prescribed threshold value; and

a control unit for performing a call access operation, in which the dial information extracted in the voice recognizing unit is used, according to a comparison result between the parameter value obtained in the voice analysis of the recognition processing of the voice recognizing unit and the prescribed threshold value.

9. A portable telephone according to

claim 8

in which an S/N ratio of the voice received in the voice inputting unit is used in the voice recognizing unit as the parameter in the voice analysis of the recognition processing.

10. A portable telephone according to

claim 8

in which a level of noise received in the voice inputting unit is used in the voice recognizing unit as the parameter in the voice analysis of the recognition processing.
