Background Changes in voice are a characteristic symptom of Huntington’s disease (HD), and can be associated with lack of motor control (dysarthria) or cognitive impairment. Objective quantitative measures of voice that can be performed within the clinic or home may provide a method to monitor disease progression and help target interventions. Aims This study aimed to compare acoustic voice features from voice recordings in English, Spanish and Polish-speaking in people with HD and controls. Methods Voice was recorded using mobile devices (Samsung Tablets Tab A and S6 Lite, and Smartphone Huawei Mate Lite 10) in participants with HD and matched control groups across three cohorts: English- (n=29), Spanish- (n=36) and Polish- (n=25) speaking. Voice was recorded during sustained vowel phonation (/a:/), syllable repetitions (/pa/,/ta/,/ka/,/pataka/,/pati/), and reading of a language-specific passage (English,1 Spanish,2 Polish3). Acoustic voice features were estimated and compared across cohorts and biological sex. Statistical analysis was performed using linear mixed models. Results Significant differences between HD and control participants were observed for the standard deviation of fundamental frequency, harmonics-to-noise ratio, jitter and shimmer (Figure 1). Effect of biological sex was observed on all features examined.
