About

The Cornell Phonetics Lab is a group of students and faculty who are curious about speech. We study patterns in speech — in both movement and sound. We do a variety research — experiments, fieldwork, and corpus studies. We test theories and build models of the mechanisms that create patterns. Learn more about our Research. See below for information on our events and our facilities.

    Linguistics Colloquium Speaker: Maher Bahloul

    The Department of Linguistics proudly presents Dr. Maher Bahloul, Visiting Scholar at Cornell University and Lecturer at Ithaca College.  Dr. Bahloul will present on "Exploring the Linguistic Landscape of Middle East Pidgin Arabic: An Analysis of Unique Features".

     

    Abstract:

     

    Middle East Pidgin Arabic (MEPA) emerges as a fascinating linguistic phenomenon in the Middle East region, representing a dynamic interplay of diverse linguistic influences. This talk delves into the unique linguistic features that characterize this pidgin, shedding light on its distinctive phonology, morphology, syntax, lexicon, and sociolinguistic dimensions. Drawing on data collected through interviews, participant observations, and linguistic analysis, the research identifies key elements that distinguish MEPA from both its parent languages and other Arabic varieties.

     

     

    The talk begins by providing a historical overview of the socio-cultural contexts that have contributed to the development of MEPA. By examining its roots in the intersection of Arabic, Urdu, Hindi, English, and other South East Asian languages, the research highlights the fluidity and adaptability that characterize MEPA as a contact language. Linguistic analysis reveals innovative phonological, morphological, and syntactic structures, lexical borrowings, and semantic shifts that define the unique linguistic landscape of Middle East Pidgin Arabic.

     

     

    Ultimately, this exploration of Middle East Pidgin Arabic contributes to a broader understanding of language contact and evolution in multilingual societies. By unraveling the distinctive linguistic features of MEPA, this study provides valuable insights into the dynamic nature of language in the Middle East region, offering a foundation for future research on pidginization, creolization, and language hybridity in diverse linguistic landscapes.

     

    Bio:

     

    Dr. Maher Bahloul holds a Ph.D. from Cornell University in Linguistics and an MA in Linguistics from Sorbonne University in Paris, France.

     

    He has taught courses in language (English, Arabic, and French), translation, and linguistics for the past 30 years. His research interest covers issues in theoretical linguistics, applied linguistics, the sociology of language, teaching and learning pedagogy, the use of arts in education, and Spoken Arabic varieties. He has taught in the United States, North Africa, and the Middle East.

     

    Dr. Bahloul has been very active with academic publishing and professional activities. He presented a variety of papers and conducted several workshops in regional and international venues. With around 100 talks and workshops and 30 peer-reviewed books, book chapters and articles, Dr. Bahloul continues to promote the fields of spoken languages, teaching and learning pedagogies, and the use of arts in education.

Facilities

The Cornell Phonetics Laboratory (CPL) provides an integrated environment for the experimental study of speech and language, including its production, perception, and acquisition.

Located in Morrill Hall, the laboratory consists of six adjacent rooms and covers about 1,600 square feet. Its facilities include a variety of hardware and software for analyzing and editing speech, for running experiments, for synthesizing speech, and for developing and testing phonetic, phonological, and psycholinguistic models.

Web-Based Phonetics and Phonology Experiments with LabVanced

 

The Phonetics Lab licenses the LabVanced software for designing and conducting web-based experiments.

 

Labvanced has particular value for phonetics and phonology experiments because of its:

 

  • *Flexible audio/video recording capabilities and online eye-tracking.
  • *Presentation of any kind of stimuli, including audio and video
  • *Highly accurate response time measurement    
  • *Researchers can interactively build experiments with LabVanced's graphical task builder, without having to write any code.

 

Students and Faculty are currently using LabVanced to design web experiments involving eye-tracking, audio recording, and perception studies.  

 

Subjects are recruited via several online systems:

 

 

 

 

Computing Resources

 

The Phonetics Lab maintains two Linux servers that are located in the Rhodes Hall server farm:

 

  • Lingual -  This Ubuntu Linux web server hosts the Phonetics Lab Drupal websites, along with a number of event and faculty/grad student HTML/CSS websites.  

 

  • Uvular - This Ubuntu Linux dual-processor, 24-core, two GPU server is the computational workhorse for the Phonetics lab, and is primarily used for deep-learning projects.

 

In addition to the Phonetics Lab servers, students can request access to additional computing resources of the Computational Linguistics lab:

 

  • *Badjak - a Linux GPU-based compute server with eight NVIDIA GeForce RTX 2080Ti GPUs

 

  • *Compute server #2 - a Linux GPU-based compute server with eight NVIDIA  A5000 GPUs

 

  • *Oelek  - a Linux NFS storage server that supports Badjak. 

 

These servers, in turn, are nodes in the G2 Computing Cluster, which currently consists of 195 servers (82 CPU-only servers and 113 GPU servers) consisting of ~7400 CPU cores and 698 GPUs.

 

The G2 Cluster uses the SLURM Workload Manager for submitting batch jobs  that can run on any available server or GPU on any cluster node. 

 

 

 

 

Articulate Instruments - Micro Speech Research Ultrasound System

We use this Articulate Instruments Micro Speech Research Ultrasound System to investigate how fine-grained variation in speech articulation connects to phonological structure.

 

The ultrasound system is portable and non-invasive, making it ideal for collecting articulatory data in the field.

 

 

BIOPAC MP-160 System

The Sound Booth Laboratory has a BIOPAC MP-160 system for physiological data collection.   This system supports two BIOPAC Respiratory Effort Transducers and their associated interface modules.

Language Corpora

  • The Cornell Linguistics Department has more than 880 language corpora from the Linguistic Data Consortium (LDC), consisting of high-quality text, audio, and video corpora in more than 60 languages.    In addition, we receive three to four new language corpora per month under an LDC license maintained by the Cornell Library.

 

 

  • These and other corpora are available to Cornell students, staff, faculty, post-docs, and visiting scholars for research in the broad area of "natural language processing", which of course includes all ongoing Phonetics Lab research activities.   

 

  • This Confluence wiki page - only available to Cornell faculty & students -  outlines the corpora access procedures for faculty supervised research.

 

Speech Aerodynamics

Studies of the aerodynamics of speech production are conducted with our Glottal Enterprises oral and nasal airflow and pressure transducers.

Electroglottography

We use a Glottal Enterprises EG-2 electroglottograph for noninvasive measurement of vocal fold vibration.

Real-time vocal tract MRI

Our lab is part of the Cornell Speech Imaging Group (SIG), a cross-disciplinary team of researchers using real-time magnetic resonance imaging to study the dynamics of speech articulation.

Articulatory movement tracking

We use the Northern Digital Inc. Wave motion-capture system to study speech articulatory patterns and motor control.

Sound Booth

Our isolated sound recording booth serves a range of purposes--from basic recording to perceptual,  psycholinguistic, and ultrasonic experimentation. 

 

We also have the necessary software and audio interfaces to perform low latency real-time auditory feedback experiments via MATLAB and Audapter.
