{c}
<Paul Boersma> is a <phonetician> who co-created <Praat> with <David Weenink>. His work connects acoustic measurements to computational methods, including the estimation of <fundamental frequency> from sampled speech.<Praat: doing phonetics by computer by Paul Boersma and David Weenink>[Intro, authorship]{ref}
His 1993 periodicity-analysis paper examines how <signal sampling> and a finite analysis window affect estimates based on <autocorrelation>. Repetition produces peaks at nonzero time lags; locating a suitable peak gives a candidate period, while the relative peak height contains information about periodicity. Correcting the influence of the analysis window is important before interpreting those peaks as properties of the original signal.<Accurate short-term analysis of the fundamental frequency and the harmonics-to-noise ratio of a sampled sound by Paul Boersma>[Sections1–3: autocorrelation, windowing and pitch-period estimation]{ref}
