Voice testing typically includes:
Consultation with an otolaryngologist: An initial medical exam by an ear-nose-throat doctor to rule out any medical conditions associated with the throat and voice.
Transnasal flexible laryngoscopy with videostroboscopy: A state-of-the-art test that involves placing a tube into the nose with a special strobe light that shows the vibration of the vocal folds.
Clinical voice evaluation: A perceptual assessment by a speech-language pathologist of muscle tension, voice quality, pitch, loudness level, resonance, breathing patterns, and prosody; Diagnostic therapy with a speech-language pathologist to determine potential for voice change.
Acoustic analysis: Recording and measurement of the voice, in order to compare the voice to norms and to monitor voice over time; This includes perturbation measures, spectrography, and electroglottography, which determines the amount of vocal fold contact during vibration.
