Abstract: Speech is the oral manifestation of language. Speech is produced by bringing air from the lungs to the larynx (respiration), where the vocal folds may be held open to allow the air to pass through or may vibrate to make a sound (phonation). In individuals with lung cancer the anatomical and physiological function is deprived. This leads speech problem due to the insufficient supply of breath to the phonatory system. This study shows reduced maximum phonation duration in individuals with lung cancer in comparison to that with normal individuals. This difference is due to the anatomical changes that takes place in the airway results in poor physiological function. The vital capacity reduces as the structure of the lung varies. In individuals with airway cancer the lung volume is deteriorated due to the growth of cancer cells or due to the increases mass of the lungs. This leads to poor breathing. Due to the shallow inspiration and expiration the duration of voicing reduces. Hence it leads to poor MPD.
