Tremor in speakers with spasmodic dysphonia
نویسندگان
چکیده
the objective of this work is the estimation of vocal tremor in patients with spasmodic dysphonia before and after treatment, and the comparison of their tremor characteristics with those estimated from healthy speakers. as an outcome, a new tremor attribute is introduced, the deviation of the modulation level and a novel method is proposed for classifying speakers according to the prevalence of tremor in their voice. results are consistent with subjective evaluations on patients who suffer from spasmodic dysphonia and confirm that the proposed method can be used for accurate estimation and objective ranking of the severity of tremor.
