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.

Colloquium Talk Series - Dominique Branson
The Cornell Linguistics Department is proud to present Dr. Dominique Branson, Soros Justice Fellow with The Open Society Foundations, Adjunct Assistant Professor at Point Park University, and former Visiting Lecturer at The University of Illinois at Chicago (UIC).
Dr. Branson will give a talk titled: "Why Language Matters for Justice: Using Linguistics to Transform the Legal System".
Abstract:
The murder of George Floyd in 2020, and the global protests that followed, reinvigorated conversations about systemic racism and reminded us that race continues to shape every facet of the U.S. legal system.
While these conversations often focus on policing and sentencing, language itself also plays a central role in producing and perpetuating inequality. In this talk, Dominique Branson (Cornell ’14) reflects on her journey from undergraduate student in Cornell’s Linguistics Department to postdoctoral scholar working at the intersection of language and criminal legal reform.
She earned her PhD in Linguistics from the University of Pittsburgh in 2023 and has since applied her training as an expert witness in criminal cases in both the U.S. and the U.K. Drawing from this experience, Branson shows that analyzing language used in routine legal procedures reveals how individual encounters map onto systemic racial inequities.
She also demonstrates how Black Americans’ language practices are misinterpreted in courts in ways that align with prevailing stereotypes about criminality, further entrenching harmful associations between race and crime.
Most recently, as a Soros Justice Fellow with the Open Society Foundations, she used linguistic methods to highlight the importance of equitable language practices in legal proceedings to promote more fair outcomes during the pretrial phase, where many racial disparities first emerge in the process.
In sharing her experiences across multiple stages of her career, she highlights the value of both traditional qualitative approaches—such as discourse and conversation analysis—and computational methods for analyzing language in legal contexts.
More broadly, she argues that applying linguistic theory and methodology not only advances the discipline’s scholarship but also enables linguists to enact meaningful social change.
Speaker Bio:
Soros Justice Fellowship. As a Soros Justice Fellow, I conduct research to document and destabilize anti-Black ideologies that legitimize pretrial dangerous predictions and harm Black communities. My aim is to abolish anti-Black pretrial practices that contribute to racial disparities in pretrial detainment and also reify the notion that Black Americans and their communities are “dangerous.” I accomplish this by considering how courtroom discourse practices reify anti-Black ideologies about Black “dangerousness.”
Teaching. At Point Park, I teach two courses in the Literature, Culture, and Society department: Introduction to Linguistics and Language and Justice. At UIC, I taught two courses in the Criminology, Law, and Justice department: Courts in Society and Language and Justice. In these courses, I inspire students to think critically about what justice is, and to think creatively about how to pursue justice using language.
Research. My research examines the relationship between Blackness, linguistic perception, language policy, and racial disparities in the criminal legal and education systems as well as in broader society. I merge disciplinary boundaries to interrogate and destabilize language ideologies and hegemonic listening practices that legitimize anti-Blackness in US institutions. For example, I have used (socio)linguistic knowledge to illuminate how linguistic practices in schools criminalize and adultify Black girls and to examine whether and to what extent listeners associate “Black-sounding” voices with criminality.
Dissertation. I completed my dissertation called, Sounding Guilty: Criminality and Black Racialized Speech” in 2023 at the University of Pittsburgh (Linguistics Department). In it, I used methods across several social science, humanistic, and critical disciplines to illuminate a link between listeners’ ideas of what it means to “sound Black” and “sound like a criminal.”

PhonDAWG - Phonetics Lab Data Analysis Working Group
No PhonDAWG today due to Fall Break.
Location: B11 Morrill Hall, 159 Central Avenue, Morrill Hall, Ithaca, NY 14853-4701, USA
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:
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:
In addition to the Phonetics Lab servers, students can request access to additional computing resources of the Computational Linguistics lab:
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
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.
