Comparative analysis of acoustic voice-quality parameters

The comparative analysis of different acoustic methods is proposed to identify the most appropriate parameters for children's voice disorders estimation. For the analysis several methods were considered: dysphonia severity index (DSI), Normalized first harmonic energy (NFHE), Voice sonority coefficient (VSC), Voice harmonization coefficient (VHC), Harmonic to noise ratio (HNR) and Jitter. The relative sensitivity was determined for each method and the most sensitive parameters were determined.
