Speech processing apparatus, medium, and method recognizing and responding to speech

A method of speech processing, the method comprising:

• extracting entity information by extracting input speech entity information from input speech and extracting a respective upper entity from a respective same domain as the input speech entity information;
• determining a focus of the input speech using the extracted input speech entity information that requires a response;
• mapping lower domain entities, of the domain, corresponding to the focus with the extracted input speech entity information;
• and
• recognizing the extracted input speech entity information according to a semantic association among domain entities, in the domain, as the input speech,
• wherein the upper entity is a hierarchically higher entity, within the domain, than the lower domain entities, the semantic association among domain entities is preset, and entity portions within the extracted input speech entity information are semantically associated with one another.

A medium comprises computer readable code to implement a method of speech processing, the method comprising:

• extracting entity information by extracting input speech entity information from input speech and extracting a respective upper entity from a respective same domain as the input speech entity information;
• determining a focus of the input speech using the extracted input speech entity information that requires a response;
• mapping lower domain entities, of the domain, corresponding to the focus with the extracted input speech entity information;
• and
• recognizing the extracted input speech entity information according to a semantic association among domain entities, in the domain, as the input speech,
• wherein the upper entity is a hierarchically higher entity, within the domain, than the lower domain entities, the semantic association among domain entities is preset, and entity portions within the extracted input speech entity information are semantically associated with one another.
