Welcome to my Homepage

My Background

I received a Doctor of Philosophy degree in Audiology and Speech Sciences from Michigan State University where I researched voice print and speech pattern recognition. My subsequent work has addressed a wide range of topics in communication sciences and disorders. I am Professor Emeritus of Health Sciences at Northern Arizona University (39 years) in Flagstaff, Arizona and own Tanner Rehabilitation Services, Inc.

I am an experienced expert witness and have taken part in many medical malpractice cases involving speech-language pathology-audiology, swallowing and communication disorders. I have been deposed, testified, or consulted with police departments, attorneys, or investigators in the following states: Arizona (several), Idaho, Florida, Washington, Texas, California, Ohio, Rhode Island, Pennsylvania, Kansas, New Hampshire, and West Virginia. Of the 15 books I have in print, three specifically address the forensics aspects of communication sciences and disorders. I have also written several journal articles on the topic and presented seminars on preventing negative dysphagia management outcomes at professional speech and hearing conventions. For a detailed summary of experience as well and a publication list, please view my resume.

Dr. Tanner in the News

Recently, some work I did with Dr. William Culbertson was profiled. Our technique is called the Tanner-Culbertson aural method of voice identification.

We hope it will enhance the ability of law enforcement and other parties to determine the identity of people based on voice alone.
