Comparison of Harmonics-to-noise Ratio Estimated in Frequency Domain with Praat
Original language description
Acoustic analysis of speech is a non-invasive technique that has been proven to be an effective tool for the objective speech assessment. In pathological speech (for example hoarseness) the harmonic-to-noise ratio (HNR) is one of the most frequently usedparameters because it can reveal additive noise in voiced parts of speech. Additive noise is a result of leak of a glottal losure during phonation which can be a consequence of vocal edema or vocal polyps for example. This paper deals with a HNR algorithm operating in frequency domain, shows strengths and weaknesses of the algorithm and tests how several algorithm settings affect results. A comparison of the results with Praat, a well-known software for voice analysis, is performed.
