Dr Jalal-eddin Al-Tamimi

Lecturer in Phonetics



I am a lecturer in experimental phonetics and phonology interested in examining the links between production, perception and learning/acquisition.

I received my BA in Jordan at Yarmouk University, Irbid in Modern Languages: French and English Language and Literature in 1998. I moved to France to Lyon II University where I obtained two BAs: BA in Teaching French as a Foreign Language (FLE) in 1999, and a BA in Language Sciences in 2000. I then obtained two MA degrees in Language Sciences, option Phonetics and Phonology in 2001 and 2002. I started working on my PhD in 2002 at the University Lyon 2 on the role of Dynamic cues in Production and Perception of vowels in Arabic and French, and earned my Diploma in 2007. I started working at the University of Newcastle in December 2007 as a Research Associate with Dr. Ghada Khattab on the Acquisition of Phonology by Lebanese Arabic speaking children. In September 2013, I was appointed as a Lecturer in Phonetics at Newcastle University.

Previous positions

2012-2013: Research Associate on an ARC-funded Discovery Project entitled "You came TO DIE?! Perceptual adaptation to regional accents as a new lens on the puzzle of spoken word recognition" with Gerry Docherty and Lecturer in Phonetics for the BSc in Speech and Language Sciences; the MSc in Language Pathology and the Integrated PhD in Phonetics and Phonology.

2010-2012: Research Associate on the project "Psychological Significance of Production Templates in Phonological and Lexical Advance: A Cross-Linguistic Study".
2007-2010: Research Associate on the project "Phonological acquisition in multilingual settings: the case of Lebanese Arabic", supervised by Dr. Ghada Khattab. My work consists of the identification of the acoustical basis of gemination in Lebanese Arabic on the adults data (12 males and 12 females), by investigating the effect of gemination on both consonants and vowels. After that, a longitudinal study will be conducted to evaluate the acquisition of geminates in Lebanese Arabic children aged 9 to 24 months in multilingual setting.

2002-2007: For my doctoral research, I carried out an investigation on the role of dynamic cues identified in production and their impact on the perception of vowels in Jordanian and Moroccan Arabic in comparison with French. By dynamic cues I mean the spectral information available in the transition between vowels and consonants, while the static ones include the mid-point values of vowel formants. A perceptual design was developed in order to test the ability of listeners of each language to identify the vocalic prototypes of their systems. Main results show that the dynamic cues do affect the identification of prototypes in each language.

2001-2007: Assitant lecturer in Acoustic Phonetics and its` application in voice therapy, at the "Institut des Sciences et Techniques de Réadaptation", Lyon 1 University, Lyon, France.
2001-2007: Research Assistant at the "Laboratoire Dynamique du Langage", CNRS and Lyon 2 University, (several contracts).

2002-2010: Member of the International Speech Communication Association, ISCA.

2002-2010: Member of the Association Francophone de la Communication Parlée, AFCP.

PhD funding opportunities

Applications are encouraged for projects in the areas of the relationship between phonetics and phonology with emphasis on laboratory phonology style studies. Studies combining both theory and experimental evidence are welcome. Experimental techniques range between acoustic analyses of the speed signal, to articulatory techniques (e.g., Ultrasound Tongue Imaging, Electroglottography, Electropalatography, Oro-nasal airflow), to speech perception and machine learning techniques. An emphasis on the multiplicity of correlates in defining phonological patterns is preferred. The work can be done on any language/dialect.
