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.

Dr. Corrine Occhino gives talk on ASL and American Deaf Culture
Dr. Corrine Occhino, Assistant Professor of Languages, Literatures, and Linguistics, Syracuse University, will give a talk titled:
What Everyone Should Know about ASL and American Deaf Culture.
ASL (American Sign Language) is experiencing a pop-culture moment. In the past few years, ASL has been visible in TV-shows, movies, commercials, and in sports and news broadcasts. ASL programs are popping up in schools and colleges all over the U.S.
Despite dips in enrollment for many college programs, student enrollment in ASL classes is at an all-time high, as it has quickly become one of the most popular languages to take on college campuses. But despite its growing popularity, the hearing world knows little about ASL, its role in Deaf culture, its status as a real, human language, or the daily frustrations many Deaf ASL signers experience as they fight for access and inclusion in a hearing world.
In this talk I will take you on a whirlwind tour of ASL and the signing communities who use it. In the first half of my talk, I will discuss ASL's roots in Deaf Education and the role segregation played in the creation of ASL varieties. I will talk about the communities of signers who use ASL, why ASL is a Deaf language, and why language deprivation is still a very real problem for deaf children in the U.S.
In the second half of my talk, I will talk about some interesting linguistic properties of ASL and what research on ASL has taught us about language, and language learning. I will end with a discussion of how learning ASL opens the door to understanding Deaf culture, but also invites us to interrogate the ways we can disrupt the hegemony of hearingness, making way for a more inclusive and equitable society.

Linguistics Colloquium talk by Dr. Carrie Dyck on Gayogo̱hó:nǫʔ and its sister languages
Dr. Carrie Dyck of the Memorial University of Newfoundland will give a Zoom Linguistics Colloquium talk titled:
Ask me anything about Gayogo̱hó:nǫʔ (and Iroquoian).
Dr. Dyck, compiler of the English-Cayuga/Cayuga-English Dictionary (University of Toronto Press 2014) and author of numerous articles on Gayogo̱hó:nǫʔ and Hodinǫhsǫ́ni, will respond to audience questions about Gayogo̱hó:nǫʔ and its sister languages.
We will try insofar as possible to gather questions for Professor Dyck before the talk. Please send your questions to John Whitman, jbw2@cornell.edu or Charlotte Logan, cjl333@cornell.edu.

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:
- * Prolific and Amazon Mechanical Turk - subjects for web-based experiments.
- * Sona Systems - Cornell subjects for for LabVanced experiments conducted in the Phonetics Lab's Sound Booth
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.
- This Linguistic Department web page lists all our holdings, as well as our licensed non-LDC corpora.
- 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.
