Speech recordings were performed according to standardized routines for high-quality recordings in a sound-proof recording studio with the equipment Sony Digital Audio Tape Deck DTC-ZE700 in a recording studio in a university department. Sopran (version 1.0.22© Tolvan Data), a software for sound processing and analyses, and a head microphone (Sennheiser HSP 4 with an MZA 900 P phantom power adapter) which was calibrated for a pre-determined mouth-microphone distance of 15 cm were used for all recordings. A recording protocol including different speech tasks was applied, providing a basis for acoustic and auditory-perceptual analyses; two approaches used for assessing voice function and quality.

Assessment was performed in the on stage of medication, within 3 weeks pre and postintervention. Testing included a speech recording according to a standardized protocol including maximum sustained phonation, syllable repetition, reading of sentences and a paragraph and monologue. Speech recordings were completed in a sound‐proof recording studio with a Sony Digital Audio Tape Deck DTC‐ZE700. The participants wore a microphone (Sennheiser HSP 4 with a MZA 900 P phantom power adapter), mounted on a headset to guarantee a constant mouth‐to‐microphone distance during recordings.
Dysarthria assessment with a standardized Swedish dysarthria test was also part of the assessment (including intelligibility testing and a self‐report questionnaire on acquired speech disorders) (Hartelius, 2015; Rusz, Tykalová, et al., 2016). Pre and postassessments were performed by an SLP who was not involved in delivering the intervention program. The external tester was also instructed to note time required for testing and any other aspects of the assessment related to feasibility. Attendance and possible adverse events were documented by the SLP leading the training. Following the intervention, the participants also filled out a questionnaire on their subjective experience of the intervention which was collected by another person than the SLP delivering treatment.
