Fall 2011 Newsletter

New additions to LIRL:

We are pleased to announce a new member of the lab, Takeshi Ikuma (Ph.D., Electrical Engineering) who has been with us since July 2011. He is a postdoctoral fellow at Louisiana State University/Health Sciences Center-Department of Otolaryngology-Head and Neck Surgery. He will be working closely with our lab as well as Our Lady of the Lake Regional Medical Center –Voice Center for the next two years to develop an objective analysis tool for laryngeal high-speed videoendoscopic (HSV) images and videoflouroscopic modified barium swallow studies. With his extensive expertise in signal processing, the LIRL will benefit from this collaboration greatly, and we are looking forward to his contributions to helping us to achieve our goals at LIRL.

Publications News

Allison Gish has completed very productive first year in her doctoral program at the LIRL. Her master thesis titled “Vocal Warm-Up Practices and Perceptions in Vocalists: A Pilot Survey” has been accepted for publication in Journal of Voice (Gish, Kunduk, Sims, McWhorter).

In addition, Allison submitted a review paper titled “Hydration: A Primer for the Speech-Language Pathologistto American Journal of Speech Language Pathology in August 2011 (Gish, Kunduk, McWhorter).

Zhenyi Wei’s work titled “A New Biomechanical Model of Vocal Fold Vibrations: Preliminary Experimental Validation” will be published in Proceedings of the 4th Annual Dynamic Systems and Control Conference, Arlington, VA. Oct 31 – Nov 2, 2011 (Wei, de Queiroz, Chen, Gunturk, Kunduk),

Together with Drs. Loehn, and McWhorter at Louisiana State University/Health Sciences Center-Department of Otolaryngology-Head and Neck Surgery, Dr. Kunduk wrote a chapter, titled “The Advanced Cancer of Larynx” (Chapter 122), which has been accepted for publication in Head and Neck Surgery-Otolaryngology (5th ed.). Eds. Bailey BJ. & Johnson JY (Loehn, Kunduk and McWhorter).

Dr. Kunduk also submitted the results of the collaborative work on investigating the effect of surgical removal of polyp on vocal fold vibratory characteristics using HSV and Phonovibrography (“Vocal Fold Vibratory behavior Changes Following Surgical Treatment of Polyps Investigated with High-Speed Video Endoscopy and Phonovibrography” to Annals. Otology, Rhinology & Laryngology (Kunduk, Doelinger, McWhorter, Svec, Lohscheller).

Funding News

Our lab is delighted to announce two new awards we received this year.

Dr. de Queiroz at the LSU-Mechanical Engineering Department and Dr. Kunduk were awarded the Louisiana Board of Regents / Experimental Program to Stimulate Competitive Research (EBSCoR). This grant will be essential to improve the clinical therapeutic device that we developed with Richie Sajan to help individuals with voice disorders. The purpose of the Voice Volume Monitor Device is to enable patients to regulate their vocal intensity in an unobtrusive manner. The device, which is about the size of a cellular phone, provides feedback to the user in the form of vibration if he/she goes over or under the desired volume during speech production and communication with others (Louisiana Board of Regents / Experimental Program to Stimulate Competitive Research (EBSCoR)-Co-P.I. Towards the Commercialization of a Phonatory Feedback Device for Individuals with Speech Disorders: Second-Generation Prototype Development. (Funded 7/1/2011-7/1/2012, $20,000).

Dr. Kunduk is delighted to receive the LSU-College of Arts and Sciences Summer Research Funding (7/1/2011, $9,000) to study the differential diagnosis of adductor spasmodic dysphonia and voice tremor using high-speed digital imaging and Phonovibrography.

Future Conference Presentations

We are very excited that our lab members’ research has been accepted for presentations at several national conferences.

Zhenyi Wei’s work titled “A new Model of Vocal Fold Vibrations: Preliminary Experimental Validation” (Wie, Queiroz, Chen, Gunturk, Kunduk) has been accepted for presentation at the 4th Annual Dynamic Systems and Control Conference in Arlington, VA, Oct. 31 – Nov. 2, 2011.

Aneesha Virani’ will present her work titled “Esophageal Complications Following Long Term Use of Tracheo-esophageal Prosthesis” as a poster session at the American Speech-Language and Hearing Association Meeting in San Diego in November 2011 (Kunduk, Schexnaildre Virani, Pou, McWhorter).

Ongoing research

Aneesha Virani has almost finished the data collection of portion of her dissertation that investigates the effects of behavioral therapy on swallowing function in patients undergoing chemoradiation for their head and neck cancer.

Jing Chen under the mentorship Dr. Gunturk and Dr. Kunduk has completed research in quantification of the vocal fold vibratory patterns during voice onset and offset and is preparing for submission of the results to a peer reviewed journal. In addition, she continues to work on developing new parameters for objective quantification of HSV data.

Allison Gish is recruiting subject for her study to investigate the contribution of the Voice Volume Monitor Device. In another study, she is analyzing HSV data to determine if high-speed digital imaging and Phonovibrography can differentiate the adductor spasmodic dysphonia and voice tremor from their vocal fold vibratory characteristics.

Dr. Kunduk and Dr. Ikuma are working together to analyze the high speed videoendoscopy data obtained from normal and pathological voices using Phonovibrography and Dr. Ikuma’s newly developed HSV parameters.

Funding opportunities for future PhD and MA Students

Funding opportunities maybe be available for future doctoral students who are interested in doing research in the area of voice and swallowing disorders. Please contact Dr. Kunduk at mkunduk@lsu.edu for further information for the funding opportunities for a doctoral degree at the Louisiana State University-Department of Communication Sciences and Disorders.

The effects of a portable ‘Voice Volume Monitor Device’ on Subjects’ communicative FUNCTION, Speech and voice quality 

The Laryngeal Imaging Research Lab is currently seeking volunteers with diagnosis of Parkinson’s disease and benign lesions of vocal folds such as nodules and polyps. to participate in a study examining the effects of a portable Voice Volume Monitor Device on communicative effectiveness and voice quality. The purpose of the Voice Volume Monitor is to enable patients to regulate their vocal intensity in an unobtrusive manner. The device, which is about the size of a cellular phone, provides feedback to the user in the form of vibration if he/she goes over or under the desired volume during speech production and communication with others. If you or someone you know is interested in participating in this study, please contact Dr. Melda Kunduk at 225-578-3930 or email her at mkunduk@lsu.edu for further information.

  • Qualification for the study:
    • People with diagnosis of
      •  Parkinson’s disease
      • Hoarseness due to the diagnosis of vocal fold nodules, polyps,
  • Location: LSU-COMD at 64 Hatcher Hall
  • Study Duration: 8 visits
  • Compensation: None
