We recorded all brief encounters using multiple synchronized acquisition systems to derive high-quality behavioral signals related to symptom severity. High-definition (1080p) webcams (Logitech c920 webcam) were placed on the table between clinician and participant and focused on the face and upper torso to optimize facial landmark detection. Both individuals (participant and clinician) wore a high-quality cardioid headset microphone (Sennheiser HSP4, Germany) to optimize audio quality and separation of the two audio streams from the two participants (“speaker diarization”), which improves transcription accuracy and facilitates individualized voice feature analysis. For a subset of sessions, additional cameras (Microsoft Kinect v1.0) were also positioned on a shelf above each participant to obtain gestural and postural signals. Signals from the two microphones and 2–4 cameras were recorded using a custom software package (“MultiSense Recorder,” CMU) that creates synchronized data streams. Here, we consider only linguistic features derived from the diarized audio.

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.

Comprehensive Dysarthria Assessment Protocol

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.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
