TLDR
Signal-averaging and autocorrelation analysis revealed that the cardiovascular system exerts a modest but consistent influence on vocal fundamental frequency (Fo), accounting for approximately 0.5% to 20% of the absolute Fo perturbation (jitter) measured during a sustained phonation.Abstract:

Reliable jitter and shimmer measurements in voice clinics :The relevance of vowel, gender, vocal intensity, and fundamental frequency effects in a typical clinical task
TL;DR: Surprisingly, in clinical assessments, voice SPL has the single biggest impact on jitter and shimmer, whereas vowel and gender effects were clinically important, whereas fundamental frequency had a relatively small influence.

Investigation of vocal jitter and glottal flow spectrum as possible cues for depression and near-term suicidal risk
TL;DR: Preliminary classification results support the hypothesized link between phonation and near-term suicidal risk, however, validation of the proposed measures on a larger sample size is necessary.

Speaker race identification from acoustic cues in the vocal signal.
TL;DR: The listeners were most successful in distinguishing voice pairs when the differences in vocal perturbation and additive noise were greatest and were least successful when such differences were minimal or absent.

The effect of relative humidity of inhaled air onacoustic parameters of voice in normal subjects
TL;DR: It is concluded that the human voice is very sensitive to decreases in RH of inhaled air, because even after a short provocation with dry air, a significant increase in perturbation measures was found.
