Understanding Aging: A 50-year longitudinal study of Speeches

June 28, 2012 in NCVS Research Papers, News

The study, published in the Journal of the American Geriatrics Society, examines 36 recordings of the former leader of the Church of Jesus Christ of Latter-day Saints, Gordon B. Hinckley, spanning the years 1958 to 2007. These recordings provide a rare opportunity to track a single individual’s age-related voice and speech mechanism changes. Speeches used from Hinckley, spanning the ages of 48 to 98 years old, were all given at Brigham Young University. Several types of analyses were employed: speech fundamental frequency to reveal the current health of the laryngeal physiology, rate of speech, as well as length of speech breath groups to indicate efficiency of laryngeal valving and/or lung vital capacity.

Two key items were discovered.  First, aging effects became noticeable between the ages of 68–74, indicating a fundamental change in the body’s maintenance of the speech mechanism. Second, rate of speech (words per minute) began to decrease precipitately at 78 years old, while length of speech breathing reduced at 70 years old.

The results of this case study can be used as a baseline for future studies. The aging of the voice and speech mechanism affects breathing, swallowing, and communication. Thus, indication of speech aging would also imply aging of the breathing and swallowing mechanism and potential health risks. Those of the world’s population over fifty are the fastest growing segment, affecting society by its sheer number as well as by historically high life spans. Healthcare practitioners must understand and accommodate the needs of this population.

Better Hearing and Speech Month Coloring Contest!

May 10, 2012 in News

Li'l VoxMay is

Better Hearing and Speech Month

 

This annual event helps increase awareness and treatment of communication disorders.
To encourage this worthwhile goal, the NCVS invites you to participate in our 1st annual

Li’l Vox COLORING CONTEST.

update: entries accepted until June 6th and voting until June 11th

Win your very own Li’l Vox clock and, if we get enough entries, a copy of Ingo R. Titze and Katherine Verdolini-Abbott’s new book: Vocology: The Science and Practice of Voice Habilitation.
 

How it works:

How to win:

  • The top three ‘liked’ entries on June 1 6  will receive their very own Li’l Vox clock.
  • Oh, and a few exceptions… due to shipping, we won’t be able to send Li’l Vox or a book to international locations. So, if you are outside the United States and happen to be one of the top ‘liked’ entries, we may ask you to provide a United States address or another means to get you the items (perhaps meet at a Voice Conference somewhere). Otherwise, your prize will just be recognition for a fine job!

But I thought you said I could win a book?

  • If we get at least 50 participating individuals submitting entries, the winner will receive their choice of books by Dr. Ingo R. Titze, including his new book Vocology.

Coloring Pages

Pick your favorite, or color multiple pictures.  Multiple entries are allowed, but you can only be one of the three winners.

There are also a few of the vocal tips which have been made into coloring pages, those could be used as well: Tired Voice, Pizza Voice, Cough Voice.

Ideas?

In response to requests made by local speech therapists in schools, we have begun to design coloring pages specifically for children with various language and speech disabilities. We want to make more, so let us know if you have ideas on how to feature Li’l Vox in a coloring page.

Lions, Tigers and … Babies? (oh my!)

November 5, 2011 in NCVS Research Papers, News

The National Center for Voice and Speech scientists (administratively led from the University of Utah) and collaborators from around the country have recently published a new paper, one more in a series of papers on large cat phonation (lions and tigers). These ongoing experiments have been conducted at the Iowa, Denver and Utah locations of the NCVS, with contributions of 11 different Ph.D. level researchers from 6 different institutions. The first of these experiments was conducted in 2005.  Special thanks to the Omaha’s Henry Doorly Zoo who donated the tissue samples.

PAPERS PUBLISHED

PRESS RELEASE

As we have worked on these papers, it became clear that the tiger has some unique vocal qualities. The most resent paper garnered a press release from the University of Utah News Center with the comparison between a child cry and a tiger roar: Born to Roar; Scientists: Lions and Tigers Roar a Bit Like Babies Cry .  This press release has resulted in several stories about our research:

ACKNOWLEDGMENTS

There have been many people who contributed to this work.  Likely we have missed one: Douglas Armstrong, Fari Alipour, Tecumseh Fitch, Eric Hunter, Sanyu Jaiswal, Sarah Klemuk, JoAnn McGee, Doug Montequin, Tobias Riede, Andrew Starr,  Ingo Titze,  Edward Walsh.

Also, the first study in 2005, we recorded high speed images (see above video) of the tiger vocal folds in vibration.  Kay-Pentax generously offered a system for loan to do the recordings.  Those high speed videos are still undergoing analysis.


Symposium on Semi-Occluded Vocal Tract Voice Therapy and Diagnostic Techniques Abstract

September 27, 2011 in News

Wordle image from abstract text.In July, the NCVS hosted a symposium on “Semi-Occluded Vocal Tract Voice Therapy and Diagnostic Techniques.”  We have compiled the abstracts in one document for your review. The symposium included research presentations and keynote addresses covering both the scientific underpinning of the semi-occluded vocal tract exercises as well as their practical application to voice habilitation and rehabilitation.  Presenters and attendees of the symposium represented a variety of states and countries and included a mix of therapists, researchers, singers, and teachers of singing.  Keynote addresses were presented by Dr. Ingo Titze, Dr.Anne-Marie Laukkanen, Dr. Joseph Stemple, Dr. Katherine Verdolini Abbott, and Prof. John Nix.  A Wordle of the abstracts is the source of the word cloud art to the right.

Dr. Titze presented the opening keynote address titled “Theoretical Underpinnings Semi-Occluded Vocal Tract Voice Assessment and Therapy” in which he clarified relatively recent findings outlining the physiologic and acoustic principals that make the SOVT therapies effective.

Subsequent speakers presented findings of recent and ongoing research project regarding both the effectiveness and the theoretical backgrounds of the SOVT techniques.

In a unique format, a group of five to six presentations was followed by an hour or more of open discussion.  This format allowed for more in-depth dialogue between presenters and attendees.  Offering this format in lieu of the more traditional five minutes of Q&A following each presentation, led to conversations being carried into the halls during break times.

Following the final session, attendees were encouraged to participate in a discussion regarding the future of vocology as a discipline and the roles and responsibilities of vocologists in the training and habilitation of voice users as well as in the research of new areas within the scope of vocology.

Planning and discussion is underway to make this type of symposium a more regular offering from the NCVS.

Soon we will have video footage of the conference talks.  And, don’t forget to check out the photos – go to: https://www.facebook.com/media/set/?set=a.231327893565300.62682.105502566147834
