Abstract-Keyword spotting is an important application of speech recognition. This research introduces a keyword spotting approach to perform audio searching of uttered words in Arabic speech. The matching process depends on the utterance nucleus which is insensitive to its context. For spotting the targeted utterances, the matched nuclei are expanded to cover the whole utterances. Applying this approach to Quran and standard Arabic has promising results. To improve this spotting approach, it is combined with a text search in case of the existence of a transcript. This can be applied on Quran as there is exact correspondence between the audio and text files of each verse. The developed approach starts by text search to identify the verses that include the target utterance(s). For each allocated verse, the occurrence(s) of the target utterance is determined.The targeted utterance (the reference) is manually segmented from an allocated verse. Then Keyword spotting is performed for the extracted reference to the corresponding audio file. The accuracy of the spotted utterances achieved 97%. The experiments showed that the use of the combined text and audio search has reduced the search time by 90% when compared with audio search only tested on the same content. The developed approach has been applied to non-transcribed audio files (preaches and News) for searching chosen utterances. The results are promising. The accuracy of spotting was around 84% in case of preaches and 88% in case of the news.
The assessment of hand functions after hand surgery treatment is essential to address the optimal rehabilitation procedures for any patient. To this aim, the current procedures anachronistically rely mainly on manual goniometers (highly prone to human errors) and know-how of experienced medical staffs (potentially prone to biased judgment), so that there is room for improvements in objective measurements of hand capabilities and new technological systems are very welcome. In particular, systems based on sensory glove are gaining more and more relevance in acquiring hand movement capabilities. Within this frame, in this research the Range of Motion (ROM) for all fingers and the ability of participants (health vs. patient subjects) to repeat two ADL (Activities of Daily Living)-based tasks were investigated. As a result, the glove-based system was evaluated in its feasibility for the assessment of hand function in clinical practice and rehabilitation settings.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
