Nasometer

This is not strictly an instrument for measuring speecharticulation as it measures acoustic energy. The purpose of a nasometer is to measure and give feedback on the presence of nasality in speech production (nasalance). It is typically used to assess the extent of nasal escape in cleft palate and provide feedback during therapy and other clinical applications. It works by measuring the acoustic output from the oral and nasal openings cavities and calculating the ratio.

The Nasometer II is marketed by Kay Elemetrics
