Abstract

Arabic Letters Phonetics can be divided from the point of view of nasal airflow, into nasal and non-nasal letters. A practical measurement has been carried out to define some nasal and non-nasal words. Two sets of word (nasal and non-nasal) have been selected. A new production of sensors is used to measure the airflow in each nostril during each word. The measurement is achieved over 25 normal subjects. The results are used to define the range of airflow for each nostril in each word. These ranges are considered as the standardization of the method to be used later with abnormalities. The system used in the measurement is a low cost dual nostril anemometer and the software is an objective tool for the diagnosis of nasal airway for each nostril.
