Voice recognition system for replacing specific domain, mobile device and method thereof

A voice recognition system, comprising:

• a mobile terminal dividing a search space for voice recognition into a general domain search space and a specific domain search space and performing voice recognition for a voice recognition target word through linkage of the general domain search space and the specific domain search space;
• and
• a voice recognition server creating and storing the specific domain search space by a request from the mobile terminal,
• wherein the specific domain search space is selected by a user,
• wherein when a predetermined specific domain search space is selected by a user, the voice recognition server performs the voice recognition for the voice recognition target word through linkage of the selected specific domain search space and the general domain search space when the selected specific domain search space is present.

A mobile device, comprising:

• a general domain search space database storing a general domain search space based on general knowledge information of which a category is not specified;
• a specific domain search space database storing a specific domain search space based on knowledge information in a specific category;
• and
• a voice recognition engine performing the voice recognition of the voice recognition target word through linkage of the general domain search space database or the specific domain search space database,
• wherein the specific domain search space database is selected by a user,
• wherein when a predetermined specific domain search space database is selected by a user, the voice recognition engine performs the voice recognition for the voice recognition target word through linkage of the selected specific domain search space and the general domain search space when the selected specific domain search space is present.

A voice recognition method for replacing a specific domain, the method comprising:

• dividing a search space for voice recognition into a general domain search space and a specific domain search space and storing the spaces;
• receiving a voice recognition target word from a user;
• and
• performing the voice recognition of the voice recognition target word based on the general domain search space and the specific domain search space,
• wherein the performing the voice recognition of the voice recognition target word based on the general domain search space and the specific domain search space comprises
• selecting, by a user, the specific domain search space;
• and
• performing the voice recognition for the voice recognition target word through linkage of the selected specific domain search space and the general domain search space when the selected specific domain search space is present.

A voice recognition method for replacing a specific domain, the method comprising:

• dividing a search space for voice recognition into a general domain search space and a specific domain search space and storing the spaces;
• selecting, by a user, a specific domain search space;
• judging whether the specific domain search space selected by the user is stored;
• loading the specific domain search space selected by the user when the specific domain search space selected by the user is stored;
• creating the specific domain search space when the specific domain search space selected by the user is not stored;
• and
• performing voice recognition through linkage of the selected specific domain search space and the general domain search space.
