Modification of texture has become the most common methods for intervention in individuals with dysphagia, and has been considered vital for promoting efficient and safe swallow. However, till date, there is no protocol to describe levels of liquid thickening or food texture modifications for clinical use. Frequently bedside swallowing evaluation is used as a diagnostic indicator for aspiration which assesses the voice quality by using the water swallow test. However, the wet voice quality may not be constantly perceived by the clinicians therefore leading to high degree of interrater variability for perceptual judgement for wetness. Similarly, eliciting phonation or speech may not be possible among the disordered. Therefore, the present study focuses on adding objectivity with perceptual findings in analysing the quality of swallow using cough with varying textures in normal individuals. The aim of the study was to determine the effect of food texture on voluntary cough in normal adult females. Cough samples of 30 normal female adults were taken and the individuals where asked to voluntarily cough post swallow for three different food textures. The analysis of cough was perceptually carried out by two experienced speech pathologists and objectively it was analysed using the Mel- Frequency Cepstral Coefficients (MFCC). Result: The study showed a difference in cough analysis for the three consistencies, the energy spectrum distribution was observed to be dispersed across the frequencies among the different consistencies.Conclusion: The present study infers the need of constant consistencies during the preliminary assessment to determine the quality of swallow.
