When English language teachers are deciding on their priorities for teaching pronunciation, it is imperative to know what kind of differences and errors are most likely to interfere with communication, and what special problems particular first-language speakers will have with English pronunciation. In other words, phoneme discrimination skill is an integral part of speech processing for the EFL learners' learning to converse in English. Training using sound visualization technique can be effective in improving second language learners' perceptions and productions of segmental and suprasegmental speech contrasts. This study assessed the efficacy of a pronunciation training that provided visual feedback for EFL learners acquiring pitch and durational contrasts to produce and perceive English phonemic distinctions. The subjects' ability to produce and to perceive novel English words was tested in two contexts before and after training; words in isolation and words in sentences. In comparison with an untrained control group, trainees showed improved perceptual and productive performance, transferred their knowledge to new contexts, and maintained their improvement three months after training. These findings support the feasibility of learner-centered programs using sound visualization technique for English language pronunciation instruction.

This study examines the recognition of the user's sound command based on speech recognition and natural language processing, and develops the natural language interface agent which can analyze the recognized command. The natural language interface agent consists of speech recognizer and semantic interpreter. Speech recognizer understands speech command and transforms the command into character strings. Semantic interpreter analyzes the character strings and creates the commands and questions to be transferred into the application program. We also consider the problems, related to the speech recognizer and the semantic interpreter, such as the ambiguity of natural language and the ambiguity and the errors from speech recognizer. This kind of natural language interface agent can be applied to the telephony environment involving all kind of communication media such as telephone, fax, e-mail, and so on.

With progressive advancements in Man-made consciousness (computer based intelligence) and Profound Learning (DL), contributing altogether to Normal Language Handling (NLP), the precision and nature of Machine Interpretation (MT) has worked on complex. There is a discussion, but that its no time like the present the human interpretation became immaterial or excess. All things considered, human flaws are consistently dealt with by its own creations. With the utilization of brain networks in machine interpretation, its been as of late guaranteed that keen frameworks can now decipher at standard with human interpreters. In any case, simulated intelligence is as yet not without any trace of issues related with handling of a language, let be the intricacies and complexities common of interpretation. Then, at that point, comes the innate predispositions while planning smart frameworks. How we plan these frameworks relies upon what our identity is, subsequently setting in a one-sided perspective and social encounters. Given the variety of language designs and societies they address, their taking care of by keen machines, even with profound learning abilities, with human proficiency looks exceptionally far-fetched, at any rate, for the time being.

본 연구는 중의성을 가진 어휘가 심성 어휘집에 표상된 방식과 감각 양상에 따른 처리 과정을 알아보기 위하여 한국어 동음동철이의 어절의 시·청각 재인 과정을 조사하였다. 청각 어절 판단 과제(실험 1)와 시각 어절 판단 과제(실험 2)를 이용한 두 실험에서 두 가지 이상의 의미를 가진 동음동철이의 어절(예: '물었다')과 단일한 의미만을 가진 통제 어절(예: '고통을')이 사용되었다. 어절 자극들의 누적 빈도는 조작하는 한편, 각 동음동철이의 어절의 다양한 의미가 가지는 상대적 빈도는 통제하였다. 어절 판단 과제를 사용한 두 실험 모두에서 유의한 빈도의 주효과와 함께 의미 수에 따른 어절 유형과 빈도 간의 상호작용이 발견되었다. 실험 1에서 청각적으로 제시된 동음동철이의 어절은 저빈도 조건에서 단의 어절에 비해 반응시간이 빠른 중의성 이득 효과가 나타난 반면, 고빈도 조건에서는 이와 반대로 비이득 효과가 나타났다. 마찬가지로 시각적으로 제시된 실험 2의 자극에서도 유사한 상호작용 패턴이 발견되었다. 본 연구 결과는 시각 및 청각 양상 모두에서 어휘-의미 처리가 상호의존적으로 이루어짐을 보여주며, 이는 의미 처리가 감각 의존적 단계보다는 일반적 어휘 지식 처리 단계에서 이루어질 가능성을 시사한다. 이와 더불어 의미 선택 과정에서 동음동철이의 어절이 가지는 다양한 의미의 후보군은 어절의 빈도가 상대적으로 낮을 때에만 촉진적 피드백을 제공함을 보여준다.

The search for relevant and actionable information is a key to achieving clinical and research goals in biomedicine. Biomedical information exists in different forms: as text and illustrations in journal articles and other documents, in images stored in databases, and as patients' cases in electronic health records. This paper presents ways to move beyond conventional text-based searching of these resources, by combining text and visual features in search queries and document representation. A combination of techniques and tools from the fields of natural language processing, information retrieval, and content-based image retrieval allows the development of building blocks for advanced information services. Such services enable searching by textual as well as visual queries, and retrieving documents enriched by relevant images, charts, and other illustrations from the journal literature, patient records and image databases.

For the Korean language, on acoustics, it creates a different form of phonetic value not a phoneme by its own peculiar property. Therefore, the construction of extended recognition system for understanding Korean language should be created with a study of the Korean rule-based system, before it can be used as post-processing of the Korean recognition system. In this paper, text-based Korean rule-based system featuring Korean peculiar vocal sound changing rule is constructed. and based on the text-based phonetic value result of the system constructed, a preliminary phonetic value segmentation border points with non-uniform blocks are extracted in Korean isolated word speech. Through the way of merge and recognition of the non-uniform blocks between the extracted border points, recognition possibility of Korean voice as the form of the phonetic vale has been investigated.

Fixed-point optimization utility software that can aid scaling and wordlength determination of digital signal processign algorithms written in C or C$\^$++/ language is developed. This utility consists of two programs: the range estimator and the fixed-point simulator. The former estimates the ranges of floating-point variables for automatic scaling purpose, and the latter translates floating-point programs into fixed-point equivalents for evaluating te fixed-point performance by simulation. By exploiting the operator overloading characteristics of C$\^$++/ language, the range estimation and the fixed-point simulation can be conducted just by modifying the variable declaration of the original program. This utility is easily applicable to nearly all types of digital signal processing programs including non-linear, time-varying, multi-rate, and multi-dimensional signal processing algorithms. In addition, this software can be used for comparing the fixed-point characteristics of different implementation architectures.

The purpose of this study was to evaluate the effects of multisensory(AVK: Auditory, Visual and Kinethetic) treatment on reading pronunciation with phonological prcessing - tensification, palatalization, and lateralization for the middle school students with delayed language development caused by mental retarded. Participants were three children with reading pronunciation difficulties in phonological processing. The following conclusions were arrived. First, three children are improved on tensifiication, palatalization, and lateralization by multisensory treatment program. Second, multisensory treatment was effective in facilitating generalization. Three children presented prominent generalization effcects in lateralization. Third, they were found to maintain partially their performance rates of the later phase of the reading with phonological processing intervention three weeks after the termination of the intervention.
