Spelling deficits have repeatedly been observed in children with dyslexia. However, the few studies addressing this issue in dyslexic adults have reported contradictory results. We investigated whether Spanish dyslexics show spelling deficits in adulthood and which components of the writing production process might be impaired in developmental dyslexia. In order to evaluate the involvement of t...

In this paper we report on our recent development work in large vocabulary,American English continuous speech dictation. We have experimented with (1) alternative analyses for the acoustic front end, (2) the use of an enlarged vocabulary so as to reduce the number of errors due to out-of-vocabulary words, (3) extensions to the lexical representation, (4) the use of additional acoustic training ...

For English learners, listening has its special importance among the four language skills. While it is the basic form of communication and foundation for developing other language skills, listening is usually regarded as the most difficult part among all kinds of English examinations. Dictation tests are now used as an economical and valid method to investigate English learners’ listening diffi...

In this paper we report on our development work in large vocabulary , American English continuous speech dictation on the ARPA NAB task in preparation for the November 1994 evaluation. We have experimented with (1) alternative analyses for the acoustic front end, (2) the use of an enlarged vocabulary of 65k words so as to reduce the number of errors due to out-of-vocabulary words, (3) extension...

Speech recognition (SR) is a technology that can improve accessibility to computer systems for people with physical disabilities or situation-introduced disabilities. The wide adoption of SR technology; however, is hampered by the difficulty in correcting system errors. HCI researchers have attempted to improve the error correction process by employing multi-modal or speech-based interfaces. Th...

A natural way to correct errors made while dictating to a computer is to respeak portions of the original sentence. But often spoken corrections are themselves misrecognized, costing the user time and testing their patience. To better understand how users behave while correcting, I created a simulated dictation interface and fooled users into believing they were correcting errors by respeaking....

BACKGROUND Electronic medical records (EMR) are considered the best solution to improved dissemination of health information for patients. The associated transcription caused a significant cost increase in an academic pediatric center. An educational campaign was implemented to achieve cost-effective transcriptions without compromising the number of EMR transcriptions. METHODS We analyzed the...

For very large vocabulary vocal dictation systems, we present a decoding strategy useful to reduce the lexical decoding cost. For each test-utterance, a sub-lexicon is selected from a very large recognition vocabulary. Such a recognition sub-lexicon is called Dynamic Lexicon (DL). Various algorithms of DL selection are developed and tested in terms of coverage rate of textual corpus. From these...
