Apparatus and system for speech intent recognition
First Claim
1. An apparatus for speech intent recognition, comprising:
- a speech recognition device configured to recognize a speech entered by a user and convert the speech into a speech text;
a speech intent recognition device configured to extract a user speech intent for the speech text using skill level information of the user and dialogue context information; and
a feedback processing device configured to extract an expression depending on the user speech intent and a speech situation of the user,wherein the speech intent recognition device selects a speech-based model among a plurality of speech-based models based on the skill level information of the user, estimates a speech intent for the speech text using the selected speech-based model, estimates a speech intent based on the dialogue context information using a dialogue context-based model, and combines the speech intent based on the speech-based model and the speech intent based on the dialogue context-based model to extract the user speech intent,wherein the apparatus for speech intent recognition outputs the expression extracted by the feedback processing device as a voice through a speaker or as a text form on a display screen,wherein the plurality of speech-based models are separately modeled for respective learner levels and classified into the respective learner levels based on philological information,wherein the dialogue context-based model is based on a list of speeches previous to the speech entered by the user, andwherein the speech intent based on the speech-based model and the speech intent based on the dialogue context-based model are simultaneously estimated.

8. An apparatus for speech intent recognition, comprising:
-
a speech recognition device configured to recognize a speech entered by a user and convert the speech into a speech text; a speech intent recognition device configured to extract a user speech intent for the speech text; and a feedback processing device configured to extract a recommended expression, a right expression, or an alternative expression according to the user speech intent and a speech situation of the user, and provides the extracted expression to the user, wherein the speech intent recognition device selects a speech-based model among a plurality of speech-based models based on skill level information of the user, estimates a speech intent for the speech text using the selected speech-based model, estimates a speech intent based on dialogue context information using a dialogue context-based model, and combines the speech intent based on the speech-based model and the speech intent based on the dialogue context-based model to extract the user speech intent, wherein the apparatus for speech intent recognition outputs the expression extracted by the feedback processing device as a voice through a speaker or as a text form on a display screen, wherein the plurality of speech-based models are separately modeled for respective learner levels and classified into the respective learner levels based on philological information, wherein the dialogue context-based model is based on a list of speeches previous to the speech entered by the user, and wherein the speech intent based on the speech-based model and the speech intent based on the dialogue context-based model are simultaneously estimated. - View Dependent Claims (9)

10. A dialogue system comprising:
-
a speech recognition device configured to recognize a speech entered by a user and convert the speech into a speech text; and a speech intent recognition device configured to extract a user speech intent for the speech text using a plurality of speech-based models which are separately generated for skill levels of the user and a dialogue context model generated by considering dialogue context information, wherein the speech intent recognition device selects one of the plurality of speech-based models based on the skill level information of the user, estimates a speech intent for the speech text using the selected speech-based model, estimates a speech intent based on the dialogue context information using the dialogue context-based model, and combines the speech intent based on the speech-based model and the speech intent based on the dialogue context-based model to extract the user speech intent, wherein the speech intent recognition device extracts an expression depending on the user speech intent and a speech situation of the user, and outputs the extracted expression as a voice through a speaker or as a text form on a display screen, wherein the plurality of speech-based models are separately modeled for respective learner levels and classified into the respective learner levels based on philological information, wherein the dialogue context-based model is based on a list of speeches previous to the speech entered by the user, and wherein the speech intent based on the speech-based model and the speech intent based on the dialogue context-based model are simultaneously estimated.
