OBJECTIVES The aim of the study is to determine the accuracy of acoustic spectrography as an outstanding tool in the characterization and monitoring of esophageal voice. MATERIAL AND METHODS Our subjects were comprised of 33 laryngectomized patients (all male) that underwent qualitative acoustic (spectrography of vowel /a/ and a sentence), quantitative acoustic (phonation time, fundamental fr...

Modern ultrafast metrology relies on the postulate that the pulse to be measured is fully coherent, that is, that it can be completely described by its spectrum and spectral phase. However, synthesizing fully coherent pulses is not always possible in practice, especially in the domain of emerging ultrashort X-ray sources where temporal metrology is strongly needed. Here we demonstrate how frequ...

present a variant of fuzzy c-means similar shapes in time series data in a scale-invariant fashion. We use data from protein mass spectrography to show how this approach finds areas of interest without a need for ad-hoc nomalizations.

ABSTRACT Dynamic vocal analysis (DVA) is an auditory-perceptual and acoustic assessment strategy that provides estimates on the biomechanics aerodynamics of production by performing frequency intensity variation tasks using voice spectrography. The objective this experience report to demonstrate use DVA in functionality dysphonic non-dysphonic individuals, with a special focus laryngeal muscula...
