What was measured

Measurement of the longest possible relaxed phonation of the voice "a" by a speech therapist The maximum phonation time (measured in seconds) for which a person can sustain a vowel sound when produced on 1 deep breath at a comfortable pitch and loudness and is a common clinical measure of glottal efficiency.

Groups in this outcome

The Measures of Central Tendency and Dispersion of Maximal Phonation Time ( MPT)

Patients who have undergone total laryngectomy and completed minimal their 6-month period without disease after surgery and post-operative treatments such as radiotherapy or chemotherapy The maximum phonation time (measured in seconds) for which a person can sustain a vowel sound when produced on 1 deep breath at a comfortable pitch and loudness and is a common clinical measure of glottal efficiency.
