Children with Dysrhythmia (due to hearing impairment) between the age of 3-12 years, Speech Language Pathologists (SLPs)
Description and Functionality
The model could be used as a normative data to determine the disrhythmia and the development of speech rhythm in Kannada speaking, typically developing children between the age of 3-12 years. Speech samples of children between the age of 3-12 years were recorded and analyzed to measure pair-wise variability index (PVI) for vocalic and intervocalic intervals based on data of frequency and intensity. The rhythm model was developed based on the data obtained on children between the age of 3-12 years (both boys and girls). The difference in speech (rhythm) of the hearing impaired child and that of a normal child has been analyzed. Thus the model essentially helps to improve the F0 contours of the hearing impaired child. The model thus helps in speech rehabilitation.
State-of-the-art
Conventionally, duration measurement has been used for the calculation of PVI values and determination of type of rhythm. This is the first study where F0 and I0 of vocalic and intervocalic intervals were measured from descriptions of pictures in children which may perhaps be better measurements of speech rhythm.
Stage of Development
The model could be used as a normative data to determine the dysrhythmia in clinical population for necessary rehabilitation and can be extended/extrapolated to any vernacular language.
