Method and system for computer assisted natural language instruction with distracters
First Claim
1. A method of computerized language instruction for a student, the method comprising:
- creating a context including a set of words and utterances selected to allow recognition of the words and utterances by a speech recognizer, and a set of distracters, which comprise sets of syllables used less frequently in the context, the sets of syllables not forming words or utterances in the context;
receiving an audio input;
comparing the input with information in the context;
if the input more closely matches a distracter than a word or utterance, ignoring the input; and
otherwise, processing the input to determine an associated word or utterance.

Abstract
A method of computerized language instruction for a student. Based on data regarding past performance of the student, an adjustable speech recognizer is adjusted. An utterance is received from the student, and the utterance is processed using the adjusted adjustable speech recognizer. The adjustable speech recognizer may comprise an Automatic Speech Recognition (ASR) engine. A set of contexts is created. Each context includes a set of words and utterances selected to allow recognition of the words and utterances by a speech recognizer. For each context, a set of subcontexts is created. Each subcontext includes the words and utterances of the context and selected mispronunciations or misarticulations of the words and utterances of the context. Recursively passing a portion of a received utterance to an ASR engine is described. According to one embodiment, a context includes a set of words and utterances selected to allow recognition of the words and utterances by a speech recognizer, and a set of distracters, which comprise sets of syllables used less frequently in the context, the sets of syllables not forming words or utterances in the context. Systems based on the described methods are disclosed.

7. A system for computerized language instruction for a student, the system comprising:
-
memory including a context having a set of words and utterances selected to allow recognition of the words and utterances by a speech recognizer, and a set of distracters, which comprise sets of syllables used less frequently in the context, the sets of syllables not forming words or utterances in the context;
logic that receives an audio input;
logic that compares the input with information in the context;
logic that, if the input more closely matches a distracter than a word or utterance, ignores the input; and
logic that otherwise processes the input to determine an associated word or utterance. - View Dependent Claims (8, 9, 10, 11, 12)
