Acoustic processing apparatus and method

An acoustic processing method of an acoustic processing apparatus based on position information, the acoustic processing method comprising:

• extracting a first acoustic model that corresponds with a first position among positions set in a speech recognition target area;
• extracting at least one second acoustic model that corresponds with, respectively, at least one second position in proximity to the first position;
• and
• generating a third acoustic model based on the first position of the first acoustic model, or a combination of the first position of the first acoustic model and the second acoustic model.

An acoustic processing method, the acoustic processing method comprising:

• setting positions in a speech recognition target area;
• extracting at least one second acoustic model corresponding to at least one second position in proximity to a first position;
• generating a third acoustic model based on weights assigned to the second positions;
• and
• recognizing an acoustic signal received from the first position of a first acoustic model using the third acoustic model.

A hardware acoustic processing apparatus comprising:

• a first extracting unit configured to extract a first acoustic model that corresponds with position information among positions set in a speech recognition target area;
• a second extracting unit configured to extract at least one second acoustic model that corresponds with, respectively, at least one second position in proximity to the position information;
• and
• an acoustic model generating unit configured to generate a third acoustic model based on the position information of the first acoustic model.
