Olivia's paper on clinically relevant cutoff scores for CPP is accepted for publication!

April 20, 2020

Congratulations to Olivia Murton for getting another publication under her belt! Her forthcoming paper is titled, "Cepstral peak prominence values for clinical voice evaluation." It will be published in the American Journal of Speech-Language Pathology.

The goal of this study was to employ frequently used analysis methods and tasks to identify values for cepstral peak prominence (CPP) that can aid clinical voice evaluation. The CPP cutoff values identified in Experiment 1 provide normative reference points for clinical voice evaluation based on sustained /a/ vowels and...

Jon Lin's IEEE paper accepted!

December 12, 2019

Jon's work on improved prediction of subglottal pressure using a neck-surface accelerometer has been accepted for publication in a special issue in the IEEE Journal of Special Topics in Signal Processing on "Automatic assessment of health disorders based on voice, speech and language processing." We incorporate features extracted using subglottal impedance-based inverse filtering of the accelerometer signal (the expertise of our colloborators in Chile)....

Katie Marks' paper published!

September 26, 2019
Katie's first first-author publication is out! Katie investigated the ability to estimate subglottal pressure (the driving pressure behind voice production) using a miniature neck-surface sensor. In particular, vocally healthy speakers were asked to produce atypical voice characteristics (breathy, strained, rough) to test the robustness of the subglottal pressures estimation models. Read it... Read more about Katie Marks' paper published!

Presentation at AQL on applying optical coherence tomography to laryngeal videostroboscopy

October 24, 2017

At the recent AQL conference in Hong Kong, Daryush presented work from a collaboration between researchers at the MGH Voice Center and optics experts at Physical Sciences, Inc.
 

4D laryngeal imaging by synchronously combining OCT with videostroboscopy

Although laryngeal videostroboscopy continues to play a central role in diagnostic, surgical, and therapeutic decisions during the management of voice disorders, videostroboscopy is limited to 2D imaging of...

Daryush's tutorial on real-world voice monitoring accepted for presentation at Interspeech 2017

July 3, 2017

Daryush's tutorial on "Real-world ambulatory monitoring of vocal behavior" was selected as one of nine tutorials that will be held at the upcoming Interspeech conference in Stockholm. See you there!

Abstract
Many of us often take verbal communication for granted. Individuals suffering from voice disorders experience significant communication disabilities with far-reaching social, professional, and personal consequences. This tutorial provides an overview of long-term,...
