چکیده
growth of information and communication technologies has influenced the research trends n speech technologies. This research explains a basic speech segmentation application for Arabic language with the aim to further develop a language tutor. The focus is on rabic as there are standards available which help in obtaining better accuracy. The roblem has been formulated in the form of a number of possible cues that could help e phoneme boundaries. These cues include zero crossing rate (ZCR), power spectral SD), formant transitions, rhythm of consonants and vowels, intonation pattern also called al frequency and vowel duration. A number of experiments were carried out involving ombinations of cues. The best results for phoneme level segmentation were observed D and ZCR whereas pitch and intensity were helpful in determining pauses. Our system strated up to 89% accuracy on continuous speech files of eight different speakers which es approximately 14300 phonemes. : Speech Segmentation, Power Spectral Density, Zero Crossing Rate, Phoneme ion.

The paper describes a speaker independent segmentation system for breaking Arabic uttered sentences into its constituent syllables. The goal is to construct a database of acoustical Arabic syllables as a step towards a syllable-based Arabic speech verification/recognition system. The proposed technique segments the utterances based on maxima extraction from delta function of 1st MFC coefficient...

Automatic speech segmentation is a key step for building large vocabulary and continuous speech recognition systems. An alternative method is to use manual speech segmentation, which is tedious, time consuming, subjective and error prone.

We annotate a small corpus of religious Arabic with morphological segmentation boundaries and fine-grained segment-based part of speech tags. Experiments on both segmentation and POS tagging show that the religious corpus-trained segmenter and POS tagger outperform the Arabic Treebak-trained ones although the latter is 21 times as big , which shows the need for building religious Arabic linguis...
متن کاملAutomatic Speech Segmentaion Using the Arabic Phonetic Database
In this paper, a special algorithm is developed to accomplish segmentation for the Arabic speech based on energy level of the uttered words or sentences. In Arabic language, phonemes can be divided into two energy regions: unvoiced phonemes are categorized as low energy, for example, the sounds / س / (/s/) and / ـه / (/h/); On the other hand, vowels and semi-vowels such as / _َ / ) هحتف ( (/ ‘a ...
