Kurzfassung: In this work, we propose an unsupervised monaural Arabic speech enhancement method that is based on two different techniques. The main idea is to determine an exact threshold value in the wavelet domain depending on the voicing state of the Arabic speech signal. Our proposed voiced/unvoiced decision algorithm based on the Multi-scale Product (MP) analysis is used. The MP is based o...

In this paper, a parity judgment task and a number naming task were used to investigate cross-notational number priming. Primes and targets could be verbal (e.g., seven) or Arabic numbers (e.g., 7), and were always presented in a different notation within the same trial (either a verbal prime and an Arabic target or an Arabic prime and a verbal target). Previous experiments showed that response...

One of the challenges related to large vocabulary Arabic speech recognition is the rich morphology nature of Arabic language which leads to both high out-of-vocabulary (OOV) rates and high language model (LM) perplexities. Another challenge is the absence of the short vowels (diacritics) from the Arabic written transcripts which causes a large difference between spoken and written language and ...

In this paper, a framework for long audio alignment for conversational Arabic speech is proposed. Accurate alignments help in many speech processing tasks such as audio indexing, speech recognizer acoustic model (AM) training, audio summarizing and retrieving, etc. We have collected more than 1,400 hours of conversational Arabic besides the corresponding human generated non-aligned transcriptio...

a community of practice may shape and reshape the identity of members of the community through providing them with situated learning or learning environment. this study, therefore, is to clarify the salient learning-based features of the language teaching community of practice that might formulate the identity of language teachers. to this end, the study examined how learning situations in two ...

the tremendous mounting interest in lipase production is pertinent to the biotechnological applications that these enzymes offer. lipase, belonging to the hydrolyze enzymes, is involved in copious biological functions including: hydrolysis insoluble triacylglycerol to mono and diacylglycerols and glycerol. submerge fermentation technique was applied for the efficient production of this. briefly...

since the verbs of and have similar use and play an important role in arabic grammar, it was useful to study both and discuss about their functions. following the discussion we found that there is five different functions for :first, it is an imperfect verb, (that give the noun an nominative case and the comment an objective case) arabic grammar experts disagree if it has a verb function or a n...

Arabic has some special syntax features which lead to complex syntax structures. We have developed a formal description of Arabic syntax in Definite Clause Grammar. This grarnrnar is characterized by its h igh descriptive power due to its dual formulat ion in terms of functions and in terms of grammatical categories. The developed g rammar has a high coverage of Arabic language and has context ...
