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.

Upcoming Events


  • 20th February 2025 04:30 PM

    ASL Lecture Series: Brendan Stern

    The Department of Linguistics and ASL Program proudly presents Brendan Stern, Ph.D., from Gallaudet University.  Dr. Stern will present on “United in Diversity, Disagreement, and Community: Lessons from Deaf America for Revitalizing American Democracy".

     

    This interactive presentation explores how viewpoint diversity, constructive disagreement, and associational life strengthen democracy in the United States. Drawing upon political psychology, political sociology, and democratic theory, it argues the Deaf community offers instructive lessons and unique remedies in this age of polarization and fragmentation.

     

    Bio:

     

    Brendan Stern, Ph.D., is an associate professor of American politics at Gallaudet University and executive director of the Center for Democracy in Deaf America (CDDA). CCDA fosters healthy democratic habits by promoting disagreement, debate, and civic engagement in American Sign Language.

     

    ASL/English interpretation will be provided.

    ASL Lecture Series: Rezenet Moges-Riedel

    The Department of Linguistics and ASL Program proudly presents Rezenet Moges-Riedel, Ed.D., from California State University, Long Beach.  Dr. Moges-Riedel will present on “Looking through critical lens on Deaf communities and intersectional issues".

     

    This workshop offers a period of self-reflection for those who are learning about Deaf and/or Disabled cultures for a greater understanding of diverse populations in signing communities of the U.S.  What does intersectionality mean in the Deaf/signing communities? Frequently, the introductions of Deaf culture are based on a singular lens, which is problematic, while concentrating on only one type of oppression with audism. Thus, this workshop will present the needed resources learning about multiple oppressions/intersectionalities within Deaf and/or Disabled communities.

     

    Rezenet Moges-Riedel, Ed.D, is an Assistant Professor and serves as a Co-Assistant Director of the ASL Linguistics and Deaf Cultures program at California State University, Long Beach. Her recent work focuses on intersectional experiences and retention of Deaf Faculty of Color, working at postsecondary institutions. Her research topics are heavily shaped by critical race theory, which she reframed "White Oralism" and "Black Deaf Gain". Her research interests also encompass in linguistic anthropological issues, such as sign language contact, demissionization, and female masculinity signing styles."

     

    ASL/English interpretation will be provided.

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.
