Provided are a method and apparatus for providing a mobile voice web service in a mobile terminal. The method includes analyzing a web history of a user from web search logs of the user and generating a voice access list based on the analysis results, and performing voice recognition by dynamically generating a voice recognition syntax according to the generated voice access list. Accordingly, by limiting syntax required for voice recognition by generating a syntax suitable for a web context of the user, efficient voice recognition, which can be performed in a terminal not a server, can be implemented.

Method, medium and apparatus for providing mobile voice web service

An apparatus and method for recognizing a voice command for use in an interactive voice user interface are provided. The apparatus includes a command intention belief generation unit that is configured to recognize a first voice command and that may generate one or more command intention beliefs for the first voice command. The apparatus also includes a command intention belief update unit that is configured to update each of the command intention beliefs based on a system response to the first voice command and a second voice commands. The apparatus also includes a command intention belief selection unit that is configured to select one of the updated command intention beliefs for the first voice command. The apparatus also includes an operation signal output unit that is configured to select a final command intention from the selected updated command intention belief and to output an operation signal based on the selected final command intention.

A device, a method, and a medium for establishing a language model for speech recognition are disclosed. The language-model-establishing device includes: a schema expander for expanding a state schema which is composed of at least one state defined by a finite state grammar using a general grammar database; a grammatical-structure-expander for expanding grammatical structures which can be expressed by each state of the expanded state schema using the general grammar database; and a grammatical-structure-filter for filtering out any incorrect grammatical structure from the expanded grammatical structures using the general grammar database. Since the state schema is expanded using the general grammar database, it is possible to improve recognition of unlearned grammatical structures.

A voice query extension method and system. The voice query extension method includes: detecting voice activity of a user from an input signal and extracting a feature vector from the voice activity; converting the feature vector into at least one phoneme sequence and generating the at least one phoneme sequence; matching the at least one phoneme sequence with words registered in a dictionary, extracting a string of the matched words with a linguistic meaning, and selecting the string of the matched words as a query; determining whether the query is in a predetermined first language, and when the query is not in the first language as a result of the determining, converting the query using a phoneme to grapheme rule, and generating a query in the first language; and searching using the query in the first language.

Provided are a method and apparatus for automatically completing a text input using speech recognition. The method includes: receiving a first part of a text from a user through a text input device; recognizing a speech of the user, which corresponds to the text; and completing a remaining part of the text based on the first part of the text and the recognized speech. Therefore, accuracy of the text input and convenience of the speech recognition can be ensured, and a non-input part of the text can be easily input based on the input part of the text and the recognized speech at a high speed.

Method and apparatus for automatically completing text input using speech recognition

The spoken dialogue interface apparatus according to an embodiment of the present invention includes a speech recognition module for recognizing a human's speech from a sound signal; a user intention interpretation module for extracting a sentence from the recognized speech and interpreting a user's intention based on the sentence; a user intention selection module for determining user intention using the interpreted user's intention and a predetermined domain action frame; and a system response generation module for generating a system response sentence corresponding to the selected user intention, wherein the domain action frame includes service information which the user requests, and parameter information which is used to perform a service, and the domain action frame is constructed to have a hierarchical tree structure.
