Dysprosody in aphasia: An acoustic analysis evidence from palestinian arabic

Bu çalışma Broca afazisi olan ve normal Filistin dili konuşan dört kişiden toplanan veri üzerinden Filistin dilininbürününün akustik incelenmesini sunmayı amaçlamaktadır. Bu çalışmada ton modülasyon, F0 aralığı, ifade sonuuzatma, kelime süresi ve hece süresini kapsayan çeşitli akustik ölçüler incelenmiştir. Sonuçlar, Broca afazilikişilerin kontrol grubuna göre ifade sonu uzatmalarını gerçekleştiremediklerini göstermiştir. Bu da konuşmaplanlaması ve zamanlamasında altta yatan zorlukları ortaya koymaktadır. Ayrıca kontrol grubuna göre Brocaafazili kişiler yüksek F0 aralığı göstermiştir. Buna rağmen, kısmen daha düzgün yüksek ve düşük entonasyonmodelleri sergilemişlerdir. Bu çalışmanın sonuçları, konuşma zamanlama eksikliklerinin ve anormal süreselmodellerin Broca afazili kişilerin konuşmalarının önemli bir özelliği olduğu Broca afazili kişilerde zamanlamave bürünsel modeller açısından önceki çalışmalarla bağlantılıdır. Bu çalışmanın sonuçları diğer dillerde özelliklediğer Arapça lehçelerine ve dillerine kıyassan daha az araştırılan Filistin Arapçasında yapılan nörolinguistikaraştırmalarına katkı sağlamaktadır.

Ahenksiz konuşma: Filistin Arapçasından akustik analiz örneği

The present study was aimed to present an acoustic analysis of Palestinian prosody based on data obtained fromfour Palestinian speaking- persons with Broca s aphasia and normal speakers. A number of acoustic measureswere examined in this study including tone modulation, F0 range, phrase-final lengthening, word duration andsyllable duration. The results indicated that Broca s aphasics were unable to implement phrase-final lengtheningcompared to the control participants, which suggests underlying deficits in speech planning and timing.Furthermore, Broca s aphasics showed higher F0 range compared to the control subjects. However, theydemonstrated relatively spared rising and falling intonation patterns. The findings of the study are in consensuswith previous studies on timing and prosodic patterns in persons with Broca s aphasia, in which speech timingdeficits and abnormal durational patterns are the significant characteristic in speech of Broca s aphasia. Theresults of the study contribute to the neurolinguistic research across different languages, specifically wherePalestinian Arabic is much less investigated compared to other Arabic dialects and languages.
