Simultaneous videoendoscopic and photodetection analyses were made of specific onset and offset times of velopharyngeal opening and closing in two normal speaking subjects. Both procedures were found to have acceptable measurement repeatability and to agree with each other when used to determine movement changes. It is felt that when used together, these techniques contribute to improved understanding of velopharyngeal activity during speech.
