Vocal Features of Methadone Therapy Patients via RBH Scale and Acoustic Analysis

A research study assessed vocal features in 34 adult patients undergoing methadone therapy for substance addiction. Subjective evaluation used the Roughness-Breathiness-Hoarseness scale, while objective analysis measured acoustic parameters from sustained vowel recordings. The work by Veljko Mirkov found statistically significant correlations between subjective and objective vocal assessment parameters.

Use Cases

• Correlating subjective RBH scale ratings with objective acoustic measures like fundamental frequency, jitter, and shimmer.
• Investigating potential vocal damage associated with methadone therapy based on patient voice recordings.
• Developing models for automated voice pathology detection using a combination of perceptual and signal-based features.

Strengths

• Includes data from 34 adult participants of both genders, providing a basis for analysis.
• Reports specific average RBH scale values (0.91 roughness, 0.38 breathiness, 0.50 hoarseness) and statistical correlations (p < 0.05, p < 0.01).
• Combines subjective perceptual assessment with objective acoustic analysis from recorded audio.

Limitations

• Row count for the underlying dataset is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
