Observational methods are fundamental to the study of human behavior in the behavioral sciences. For example, in the context of research on intimate relationships, psychologists’ hypotheses are often empirically tested by video recording interactions of couples and manually coding relevant behaviors using standardized coding systems. This coding process can be time-consuming, and the resulting coded...
We propose a glottal source estimation method robust to shimmer and jitter in the glottal flow. The proposed estimation method is based on a joint source-filter optimization technique. The glottal source is modeled by the Liljencrants–Fant (LF) model and the vocal-tract filter is modeled by an auto-regressive filter, which is common in the source-filter approach to speech production. The optimization...
