Problems solved by technology

Of course, in the above-mentioned oral dialogue training process with the user, the system will also perform some simple error prompts. These error prompts mostly occur when the user's spoken voice does not match the demonstration voice and require the user to complete the spoken dialogue training again; In this process, the system does not provide heuristic feedback and evaluation on the user's oral learning situation, especially it cannot heuristically capture the errors in the user's oral language, and correct and guide the errors; the result is that the user Unable to discover their deficiencies in time, so that they can practice in a targeted manner to improve their oral English
[0004] In short, the existing computer systems used to assist oral language learning cannot heuristically induce users to learn oral language in depth, and often cause learners to blindly imitate the correct oral pronunciation without getting rich guidance information from the interaction with the system. The performance is not perfect. It can be seen that providing a computer system with perfect performance to assist oral language learning is an important issue to be solved urgently.

Embodiment Construction

[0047] Specifically, the invention discloses a computer system for assisting spoken language learning, which uses speech recognition and speech and language analysis techniques to generate pattern features related to spoken language learning, and uses structured teaching pattern information (especially error patterns) , and intelligently feed back rich teaching guidance information. Possible acoustic and linguistic pattern features (learning errors or multiple spoken expressions of the same meaning) can be gleaned from actual foreign language teaching cases. The present invention uses a machine learning method to analyze the above pattern, and obtains a set of concise feature vectors to reflect different teaching directions. These feature vectors can be combined to give specific or general scores for different instructional content, such as pronunciation, fluency, or correct use of grammar. By statistically regressing these machine ratings with those of human teachers, a high...

Abstract

The invention discloses a computer system for assisting spoken language learning, comprising the following components of a user interface for prompting a user to complete a certain spoken language learning content and collect voice response data of the user; a database which comprises a group of mode features used for describing the performances on acoustic and linguistic aspects which are related to the spoken language learning of the user; a voice analysis system for analyzing the voice response data and extracting acoustic mode features or linguistic mode features; a mode matching system for correspondingly matching one or more subsets in the mode feature extracted from the voice response data with the mode features in the database and generating feedback data according to the matching result; and a feedback system for feeding data back to the user and assisting the user to master the spoken language learning content. The computer system has higher interactivity and self-adaptability and can particularly heuristicly capture user errors and intelligently feed back rich teaching instruction information, thereby making up for deficiencies of the prior art on the aspect.

Description

technical field [0001] The invention relates to a computer system for assisting oral language learning. Background technique [0002] Due to the lack of a language practice environment and targeted individual tutoring, oral language learning is the most difficult part of learning a foreign language. Although computers have been used to assist language learning in a general sense, in the field of oral language learning, the effect of computer-assisted teaching is still limited and unsatisfactory. At present, some technologies related to speech recognition and pronunciation evaluation have been initially used to assist oral language learning, but their performance is still very limited. [0003] Such as WO 2006 / 031536; WO 2006 / 057896; WO 02 / 50803; US 6,963,841; US ​​2005 / 144010; Oral language learning methods and corresponding computer systems, but the use of speech recognition and pronunciation evaluation related technologies in such methods and systems is mostly limited to...
