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: Amanda Rysling to speek on Linguistic Efficiency and what it takes to comprehend (a) focus
The Cornell Linguistics Department proudly presents Linguistics Colloquium Speaker Dr. Amanda Rysling. Assistant Professor at the University of California, Santa Cruz.
Dr. Rysling will give a talk titled: "A new window on linguistic efficiency: what it takes to comprehend (a) focus."
Funded in part by the GPSAFC and Open to the Graduate Community.
Abstract:
Over the past half-century, psycholinguistic studies of linguistic focus — often described only as the most important or informative material — have found that comprehenders preferentially attend to focused material and process it more "deeply" or "effortfully" than non-focused material.
But psycholinguists have investigated only a limited subset of focus constructions, and we have not come to an understanding of how costly focus is to process, what factors govern that cost, or why the language comprehension system behaves in the way that it does, and not others.
In this talk, I discuss the problem for language comprehenders presented by the category of focus, and present evidence that focus processing is generally costly, but this cost can be attenuated by the presence of contrastive alternatives to a focus in the context before that upcoming focus, as would be expected on the basis of proposals in formal semantics (see Rooth, 1992, i.m.a.).
Evidence from the processing of second-occurrence foci demonstrate that comprehenders seem to work harder than our general models of sentence processing would posit that they should have to in comprehending given focused material.
These findings add to our understanding of what it means to be good enough or efficient in language processing, delineating conditions under which comprehenders do (not) find apparently important material to be worth processing deeply or effortfully.
Bio:
Dr. Rysling is an assistant professor in the Department of Linguistics at the University of California, Santa Cruz. She is interested in how language is represented and processed; in particular, she seeks cases in which the processing of a linguistic unit is affected by the phonetic, phonological, or prosodic context in which that unit occurs.
This theme unifies her work on segmental perception, lexical bias effects, cues to prosodic structure, sonority sequencing and vowel alternations in Polish, and, more recently, semantic representation and processing.
Her name is pronounced either [rɨslɨŋ], with igryk, or [ɹislɨŋ], like the wine.

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.
