The success of nonlinear noise reduction applied to a single channel recording of human voice is measured in terms of the recognition rate of a commercial speech recognition program in comparison to the optimal linear filter. The overall performance of the nonlinear method is shown to be superior. We hence demonstrate that an algorithm that has its roots in the theory of nonlinear deterministic...

The present study investigated a bandwidth extension method to enhance telephone speech understanding for cochlear implant (CI) users. The acoustic information above telephone speech transmission range (i.e., 3400 Hz) was estimated based on trained models describing the relation between narrow-band and wide-band speech. The effect of the bandwidth extension method was evaluated with IEEE senten...

In the present feasibility study, e-supervision was used to provide university liaison supervision to speech-language pathology (SLP) graduate students enrolled in student teaching practica. Utilizing a mixed methodology approach, interview and survey data were compared in order to identify similarities and differences between in-person and e-supervision, and guide future practice. Results show...

Cochlear-implant users perform far below normal-hearing subjects in background noise. Speech recognition with varying numbers of competing female, male, and child talkers was evaluated in normal-hearing subjects, cochlear-implant users, and normal-hearing subjects utilizing an eight-channel sine-carrier cochlear-implant simulation. Target sentences were spoken by a male. Normal-hearing subjects...

1 はじめに 我々は,ポッドキャストを音声認識によって 自動的にテキスト化することで,それらをユー ザが全文検索できるだけではなく,詳細な閲覧, 編集も可能なソーシャルアノテーションシステ ム「PodCastle1)2)3)」の開発,運営を行っている. ポッドキャストは実環境の多様な音声データであ り,従来の音声認識技術では高い認識率を達成す ることは難しい.そこで PodCastleでは,多数 のユーザに認識誤りを訂正 (アノテーション)す る協力をしてもらうことで,音声認識率をシス テムの運用中に向上させる枠組みを採用してい る.こうすることで,検索サービスとしての質を 向上させるだけでなく,音声認識技術の底上げを はかることも狙っている. 本研究では,上記の枠組みの一環として,PodCastleを通じて得られる集合知,すなわちユー ザによる音声認識誤りの訂正結果を活用した音 響...

introduction: in early typical language development, children understand words before they are able to use them in speech. children with autism spectrum disorders (asd) generally show impairments in both the comprehension and the production of language. however, the relative degree of delay or impairment in each of these sub-domains may also be atypical and remains less well-understood. materia...

INTRODUCTION Difficulties in accessing allied health services, especially in rural and remote areas, appear to be driving the use of telehealth services to children in schools. The objectives of this study were to investigate the experiences and views of school executive staff and therapy assistants regarding the feasibility and acceptability of a speech-language pathology telehealth program fo...

Computers have been used for language teaching ever since the 1960's.Learning a second language is a challenging endeavor, and, for decades now, proponents of computer assisted language learning (CALL) have declared that help is on the horison. We investigate the suitability of deploying speech technology in computer based systems that can be used to teach foreign language skills. In this case,...

BACKGROUND Hyperkinetic dysarthria is characterized by abnormal involuntary movements affecting respiratory, phonatory, and articulatory structures impacting speech and deglutition. Speech-language pathologists (SLPs) play an important role in the evaluation and management of dysarthria and dysphagia. This review describes the standard clinical evaluation and treatment approaches by SLPs for ad...
