Acoustic Voice Analysis

If you have asthma or a vocal nodule, your condition may adversely affect the power supply of your voice, especially if you rely on your voice in your vocation. An otolaryngologist and voice therapist at Jefferson will evaluate your voice quality by performing an acoustic voice analysis, also known as objective measures.

Recordings of your speaking and singing voice are taken and acoustic parameters (pitch, loudness and range) are measured using sophisticated voice software. Normative data has been established for these acoustic measures and they are useful in helping our staff define the voice problem and in guiding voice therapy.

The Jefferson Voice and Swallowing Center, a joint program with the Department of Rehabilitation Medicine and housed within the Department of Otolaryngology–Head and Neck Surgery, provides voice care to many theatrical performers in the Philadelphia region, as well as visiting professional singers and musicians.
