TLDR
Vocal abnormalities (hoarseness, breathiness, articulatory pattern and inteligibility), as well as perceptive-auditory analysis, showed statistically significant differences between pre and post treatment groups.Abstract:
Mild changes in voice quality and articulation of speech may be seen in early phases of Parkinson´s disease (PD). Voice and speech disturbances in PD constitute a hypocinetic dysarthria or dysarthrophonia and are characterized by monotony and reduced intensity of voice, imprecise articulation and disturbances of rhythm. Favorable results with an intensive method (Lee Silverman Voice Treatment) for the treatment of voice disturbances in PD were recently reported. The main goal of the method is to augment vocal intensity through the increment of phonatory effort. The purpose of the present study was to characterize vocal abnormalities (hoarseness, breathiness, articulatory pattern and inteligibility) in a group of patients with PD and to evaluate the therapeutic efficacy of the Lee Silverman method. Acoustic as well as perceptive-auditory analysis showed statistically significant differences between pre and post treatment groups. Although the articulatory pattern has not considerably changed, the benefits obtained with the improvement in vocal quality positively influenced overall quality of oral communication.read more

Glottal airflow and transglottal air pressure measurements for male and female speakers in soft, normal, and loud voice
TL;DR: Recordings of productions of syllable sequences in soft, normal, and loud voice showed that with change from normal to loud voice, both males and females produced loud voice with increased pressure, accompanied by increased ac flow and increased maximum airflow declination rate.

TL;DR: In this study, the frequency of occurrence of speech and voice symptoms in 200 Parkinson patients was defined by two expert listeners from high-fidelity tape recordings of conversational speech samples and readings of the sentence version of the Fisher-Logemann Test of Articulation Competence.

Comparison of Two Forms of Intensive Speech Treatment for Parkinson Disease
TL;DR: Investigation of the effect of two forms of intensive speech treatment on the speech and voice deficits associated with idiopathic Parkinson disease suggests intensive voice and respiration treatment is more effective than respiration (R) treatment alone for improving vocal intensity and decreasing the impact of Parkinson disease on communication.
