Abstract

The present invention discloses a method and device for voice control, which are used to solve the problem of low success rate of voice control in the prior art. The method includes: classifying stored recognition information used for voice recognizing to obtain a syntax packet corresponding to each type of recognition information (10); receiving an inputted voice signal, and performing a voice recognition processing respectively on the received voice signal by using each obtained syntax packet in turn (20), and performing a corresponding control processing based on a voice recognition result of the voice signal according to each syntax packet (30).

Claims

1. A method for voice control, comprising the following steps:

classifying stored recognition information used for voice recognition to obtain a syntax packet corresponding to each type of recognition information;

receiving an inputted voice signal, and performing a voice recognition processing respectively on the received voice signal by using each obtained syntax packet in turn; and

, performing a corresponding control processing based on a voice recognition result of the voice signal according to each syntax packet.

2. The method according to claim 1, wherein, the step of performing a voice recognition processing on the received voice signal according to each syntax packet specifically comprises:

when at least one piece of recognition information in the syntax packet can be recognized from the received voice signal, selecting an identifier corresponding to the recognized recognition information from identifiers corresponding to various recognition information in the pre-designated syntax packet as the voice recognition result of the syntax packet on the voice signal;

otherwise determining that voice recognition of this time fails, and selecting an identifier corresponding to a reason for voice recognition processing failure of this time from identifiers corresponding to pre-designated various reasons for voice recognition processing failure as the voice recognition result of the syntax packet on the voice signal.

3. The method according to claim 2, wherein, the step of performing a corresponding control processing on a voice recognition result of the voice signal according to each syntax packet specifically comprises:

when there is at least one identifier corresponding to the reason for voice recognition processing failure in the voice recognition result of each syntax packet on the voice signal, outputting a prompt signal for prompting voice recognition failure.

4. The method according to claim 2, wherein, the step of performing a corresponding control processing on a voice recognition result of the voice signal according to each syntax packet specifically comprises:

counting a number of identifiers corresponding to a same reason for voice recognition processing failure in the voice recognition result of each syntax packet on the voice signal, and prompting a user for the reason for voice recognition processing failure corresponding to the identifier of the largest number through a prompt message.

5. The method according to claim 2, wherein, the step of performing a corresponding control processing on a voice recognition result of the voice signal according to each syntax packet specifically comprises:

when there is no identifier corresponding to the reason for voice recognition processing failure in the voice recognition result of the designated syntax packet on the voice signal, performing a predetermined control processing corresponding to the voice recognition result of the designated syntax packet on the voice signal according to the voice recognition result of the designated syntax packet on the voice signal.

6. The method according to claim 2, wherein, the step of performing a corresponding control processing based on a voice recognition result of the voice signal according to each syntax packet specifically comprises:

combining the voice recognition results of various syntax packets on the voice signal in a predetermined combining order, and sending a combination result to external equipment; and

,

receiving a query request sent from the external equipment, and the query request comprising a splitting result obtained after the external equipment splits the combination result in a splitting order corresponding to the predetermined combining order; and

,

selecting recognition information corresponding to the splitting result contained in the query request from a pre-designated corresponding relationship between the recognition information and the identifier;

providing the recognition information corresponding to the splitting result to the external equipment, and the external equipment performing the control processing according to the recognition information corresponding to the splitting result.

7. The method according to claim 1, wherein, the recognition information used for voice recognition comprises information of contact name type, information of contact way type and information of operation type.

11. The method according to claim 2, wherein, the recognition information used for voice recognition comprises information of contact name type, information of contact way type and information of operation type.

12. The method according to claim 3, wherein, the recognition information used for voice recognition comprises information of contact name type, information of contact way type and information of operation type.

13. The method according to claim 4, wherein, the recognition information used for voice recognition comprises information of contact name type, information of contact way type and information of operation type.

14. The method according to claim 5, wherein, the recognition information used for voice recognition comprises information of contact name type, information of contact way type and information of operation type.

15. The method according to claim 6, wherein, the recognition information used for voice recognition comprises information of contact name type, information of contact way type and information of operation type.

8. A device for voice control, comprising:

a syntax packet obtaining unit, which is used to classify stored recognition information used for voice recognition to obtain a syntax packet corresponding to each type of recognition information;

a voice recognition processing unit, which is used to receive an inputted voice signal, and perform a voice recognition processing respectively on the received voice signal by using each syntax packet obtained by the syntax packet obtaining unit in turn;

a performing unit, which is used to perform a corresponding control processing based on a voice recognition result of the voice signal according to each syntax packet.

9. The device according to claim 8, wherein, the voice recognition processing unit specifically comprises:

a first determining sub-unit, which is used to, for reach syntax packet obtained by the syntax packet obtaining unit, when at least one piece of recognition information in the syntax packet can be recognized from the received voice signal, select an identifier corresponding to the recognized recognition information from identifiers corresponding to various recognition information in the pre-designated syntax packet as the voice recognition result of the syntax packet on the voice signal;

a second determining sub-unit, which is used to, when no recognition information in the syntax packet can be recognized from the received voice signal, determine that voice recognition of this time fails, and select an identifier corresponding to a reason for voice recognition processing failure of this time from identifiers corresponding to pre-designated various reasons for voice recognition processing failure as the voice recognition result of the syntax packet on the voice signal.

10. A device for voice control connected with external equipment, comprising:

a syntax packet obtaining unit, which is used to classify stored recognition information used for voice recognition to obtain a syntax packet corresponding to each type of recognition information;

a voice recognition processing unit, which is used to receive an inputted voice signal, and perform a voice recognition processing respectively on the received voice signal by using each syntax packet obtained by the syntax packet obtaining unit in turn;

a combining sub-unit, which is used to combine the voice recognition results of various syntax packets obtained by the voice recognition processing unit on the voice signal in a predetermined combining order, and send a combination result to the external equipment;
