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.

Exploring Deaf Culture - 7:30pm, Wednesday Nov 4, 2020
Deaf culture consists of a set of values in deaf people, including the importance of using sign languages as the main communication. It allows deaf individuals to express themselves.
Danielle Graybill is a graduate student in Teaching American Sign Language at the University of Northern Colorado. She is completing her last semester and is thrilled to be interning with the Department of Linguistics at Cornell University. She was born deaf and ASL is her first language. Ms. Graybill loves traveling, outdoor activities, and exploring hidden gems.

Thursday, Nov 5, 9:30PM - Special Lecture by Dr. Margaret Renwick: Structural, lexical, and social factors in Romance vowel changes
Cornell Phonetics Lab alumnus Prof. Margaret Renwick (University of Georgia) will give a Zoom talk on "Structural, lexical, and social factors in Romance vowel changes". This talk is sponsored by the Chulalongkorn University Department of Linguistics.
Location: Event Registration
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.
Computing Resources
The Phonetics Lab maintains two Linux servers that are located in the Rhodes Hall server farm:
- Lingual - This web server hosts the Phonetics Lab Drupal websites, along with a number of event and faculty/grad student HTML/CSS websites.
- Uvular - This 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 uses the SLURM Workload Manager for submitting batch jobs that can run on any available server or GPU on any cluster node. The G2 cluster currently contains 159 compute nodes and 81 GPUs.
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.
Ultrasound
Our GE LOGIQbook portable ultrasonic imaging system is used for studying vocal tract kinematics and dynamics.
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.
