Abstract

A voice control method and a voice control system are provided. The voice control method is adapted to a voice control apparatus connected to a local area network. The voice control method includes following steps. Voice data is received. A voice recognition is executed for the voice data to obtain voice print information and a prompt command corresponding to the voice data. Permission information corresponding to the voice print information is determined according to the voice print information and the prompt command. At least one electronic apparatus is controlled through the local area network according to at least one of the permission information, the prompt command and environment information.

Claims

1. A voice control method, adapted to a voice control apparatus connected to a local area network, the voice control method comprising:

receiving a first voice data;

executing a voice recognition for the first voice data in order to obtain a first voice print information and a first prompt command corresponding to the first voice data;

determining a first permission information corresponding to the first voice print information according to the first voice print information and the first prompt command; and

controlling at least one electronic apparatus through the local area network according to at least one of the first permission information, the first prompt command and an environment information.

2. The voice control method as claimed in claim 1, wherein the step of determining the first permission information corresponding to the first voice print information according to the first voice print information and the first prompt command comprises:

selecting one of a plurality of permission levels to be set as the first permission information according to the first voice print information;

providing a user state corresponding to the first voice print information;

recording a location information included by the first prompt command into the user state; and

updating the permission level of the first permission information when the user state is changed according to the location information.

3. The voice control method as claimed in claim 2, wherein the step of recording the location information included by the first prompt command into the user state comprises:

determining whether the first prompt command comprises the location information; and

recording the location information into the user state when the first prompt command comprises the location information.

4. The voice control method as claimed in claim 2, wherein the step of updating the permission level of the first permission information when the user state is changed according to the location information comprises:

adjusting the first permission information into another one of the permission levels according to the user state.

5. The voice control method as claimed in claim 2, wherein the permission level of the first permission information is used to determine an apparatus amount, a function amount or a combination thereof for the at least one electronic apparatus controlled by the first voice print information.

6. The voice control method as claimed in claim 2, wherein the step of controlling the at least one electronic apparatus through the local area network according to at least one of the first permission information, the first prompt command and the environment information comprises:

limiting the first voice data from controlling the at least one electronic apparatus according to the first permission information when the environment information matches a specific time interval.

7. The voice control method as claimed in claim 1, further comprising:

receiving a second voice data;

executing the voice recognition for the second voice data to obtain a second voice print information and a second prompt command corresponding to the second voice data, wherein the second voice print information is different from the first voice print information;

determining a second permission information corresponding to the second voice print information according to the second voice print information and the second prompt command; and

increasing a permission level of the second permission information according to the first permission information when a user state corresponding to the first voice print information is recorded with a specific location information and the first permission information is higher than the second permission information.

8. The voice control method as claimed in claim 1, wherein the voice control apparatus comprises a voice print database and a plurality of voice databases, the voice print database records a plurality of preset voice prints corresponding to the voice databases respectively, each of the voice databases records a plurality of preset audio signals, and the step of executing the voice recognition for the first voice data in order to obtain the first voice print information and the first prompt command corresponding to the first voice data comprises:

obtaining the first voice print information in the first voice data according to a characteristic parameter of the first voice data;

comparing whether the first voice print information matches one of the preset voice prints in the voice print database; and

if yes, obtaining one of the voice databases corresponding to the preset voice print matching the first voice print information and setting said one of voice databases as a specific voice database corresponding to the first voice data;

comparing whether the first voice data matches at least one of the preset audio signals in the specific voice database; and

if yes, setting the preset audio signal matching the first voice data as the first prompt command.

9. The voice control method as claimed in claim 8, further comprising:

updating the specific voice database according to an input operation.

10. The voice control method as claimed in claim 1, wherein the voice control apparatus comprises a voice print database, and the voice print database records a plurality of preset voice prints, and the voice control method further comprises:

determining whether the first prompt command comprises an apparatus information of the at least one electronic apparatus; and

searching for a specific voice print corresponding to the highest permission level among the preset voice prints when the first prompt command comprises the apparatus information, and transmitting a prompt message to a user corresponding to the specific voice print.

11. The voice control method as claimed in claim 1, wherein the voice control apparatus comprises a voice print database, the voice print database records a plurality of preset voice prints, and the step of controlling the at least one electronic apparatus through the local area network according to at least one of the first permission information, the first prompt command and the environment information comprises:

obtaining a plurality of user states corresponding to the preset voice prints respectively when the environment information is determined to be a specific time point;

determining whether each of the user states is set as a specific location information; and

executing an operation mode corresponding to the specific time point to control the at least one electronic apparatus when none of the user states is set as the specific location information.

12. A voice control system, comprising:

at least one electronic apparatus, comprising;

a first communication unit, connected to a local area network; and

a voice control apparatus, comprising;

a second communication unit, connected to the local area network;

a storage unit, recording a plurality of modules; and

a processing unit, coupled to the second communication unit and the storage unit, and configured to access and execute the modules recorded in the storage unit, the modules comprise;

a voice communication module, receiving a voice data;

a voice assistant module, executing a voice recognition for the voice data to obtain voice print information and a prompt command corresponding to the voice data;

a permission setting module, determining a permission information corresponding to the voice print information according to the voice print information and the prompt command; and

a control module, controlling the at least one electronic apparatus through the local area network according to at least one of the permission information, the prompt command and an environment information.
