The book  begins with an overview of the anatomy and physiology of voice production.  The chapter on voice evaluation includes terminology, rating scales, instrumental and noninstrumental assessment, and report writing.  An overview of 23 voice disorders is given with their etiology, presentation, and treatment/therapy suggestions.  Topics include:

  • Functional Voice Disorders: functional aphonia, paradoxical vocal fold movement (PVFM), muscle tension dysphonia (MTD) and more
  • Neurological Voice Disorders: vocal fold paralysis and spasmodic dysphonia (SD)
  • Organic Voice Pathologies: polyps and nodules, granuloma, reflux laryngitis, sulcus vocalis, papilloma, and cancer
  • Gastro-Esophogeal Reflux Disease (GERD)
  • Neurological Conditions Affecting the Voice: pseudobulbar palsy, myasthenia gravis, essential tremor, Parkinson's disease, Huntington's Chorea, and more

Various treatment approaches are reviewed and specific exercises and therapy activities are given for:  

  • vocal hygiene
  • voice therapy theories and approaches (e.g., resonant voice therapy, laryngeal massage)
  • therapy exercises/tasks
    - physical exercises
    - respiration/airflow
    - phonation
    - resonance

Copy the activity pages or print them out from the FREE CD.  Extra helps include:

  • voice, respiration, and resonance exercise sheets
  • evaluation tools
  • voice handicap index
  • example treatment plans
  • sample protocols
  • consent forms
  • patient questionnaire
  • educational handouts

  • Of the general population, 29.9% will experience a voice disorder in their lifetime (Roy, Merrill, Gray, & Smith, 2005).
  • New advances and techniques are being adapted into clinical practice for the assessment of vocal function (Mehta & Hillman, 2008).
  • Data reported in the literature supports the use of voice therapy in the management of patients with both acute and chronic voice disorders (ASHA, 2005).
  • Voice therapy contributes to increased treatment efficacy of voice disorders (ASHA, 2005).
  • Voice therapy contributes to the cost-effectiveness of medical and surgical treatment outcomes for patients with voice disorders and vocal pathologies (ASHA, 2005).

The Source for Voice Disorders Adolescent & Adult incorporates these principles and is also based on expert professional practice.

M.S., SLP, received her master's degree in speech-language pathology from Duquesne University, Pittsburgh, Pennsylvania.  She has specialized in the evaluation and treatment of voice disorders.  Kelly is currently providing outpatient services in ENT private practice settings.  Kelly is employed by Metropolitan ENT Associates in Pittsburgh.


The field of speech-language pathology is rapidly evolving into a diverse profession with sub-specialties in many areas of education and rehabilitation.  This trend is highlighted by the institution of ASHA's special interest divisions and the current trends toward specialty recognition.  Over the past 20 years, there has been a dramatic increase in the involvement of speech-language pathologists (SLPs) in the evaluation and treatment of voice disorders.  Collaboration between ENT physicians and SLPs is now the gold standard of care for patients presenting with a wide variety of conditions that may affect the voice.

As this trend develops, many SLPs are obtaining continuing education to gain current knowledge in a rapidly changing field.  It is vital that we have a working knowledge of disorders and pathologies that we are now being asked to treat.  This "working knowledge" calls upon our ability to incorporate anatomy, neurology, speech science, and voice training.

There are many current texts in the area of evaluation and treatment of voice; however, there are few available resources for treatment ideas and stimulus tasks.  Many clinicians are adapting therapy materials and stimuli from motor speech manuals/workbooks to target voice goals.

The Source for Voice Disorders Adolescent & Adult is designed to assist clinicians with both the evaluative tools and therapy tasks to provide services to patients with both functional and medical (organic/neurological) diagnoses.  It is a functional, clinical manual useful for clinicians with varying degrees of experience with voice disorders.

Treating patients with voice disorders may be intimidating for many clinicians, generally because the clinicians treat these patients relatively infrequently.  Therefore, this book is organized to provide easy reference of a diagnosis with etiology, physiology, and corresponding recommendations for treatment.

  • Chapter 1 serves as a reference to identify anatomic landmarks relative to the larynx and respiratory system and as a review of neurological diagnoses and their effects on voice and speech.
  • Chapter 2 focuses on evaluation techniques and development of appropriate goals and treatment plans.
  • Chapter 3 covers a multitude of vocal disorders and pathologies.  These first three chapters offer diagnostically useful information as well as suggestions for treatment.
  • Chapter 4 is a compilation of therapy tasks and stimuli designed for use with patients and can be photocopied for home practice.
  • Chapter 5 reviews evaluation and treatment of head and neck cancer patients, including laryngectomy and vocal rehabilitation.

A glossary of terms and a list of resources have also been included for clinical reference as well as a list of references used in the compilation of this book.

The evaluation and treatment of voice disorders is a collaborative process involving many professionals.  Keep in mind the medical and social aspects of the disorder to make appropriate referrals and coordinate effective interdisciplinary treatment.  These patients offer new challenges to our clinical skills and being an integral part of their rehabilitation can be extremely rewarding.
