الملخص	The Stuttering Severity Instrument–Fourth Edition (SSI-4) is the standard clinician-administered measure of stuttering severity in children (ages 2–13) and adults (ages 14–75). Developed by Riley (2009), SSI-4 quantifies stuttering through three behavioral components: frequency (percentage of syllables stuttered), duration (average length of stuttering moments), and physical concomitants (observable tension and associated movements). SSI-4 Severity Scores enable reliable tracking of treatment response, prognosis estimation, and comparison across populations, making it essential for evidence-based stuttering assessment and research.	The Voice Handicap Index (VHI) is a 30-item self-report questionnaire that measures the impact of voice disorders on quality of life and functional communication. Developed by Jacobson and colleagues in 1997, it quantifies the psychosocial, physical, and emotional burden of dysphonia across functional, physical, and emotional domains. Widely used in otolaryngology and speech-language pathology to assess treatment outcomes and monitor disease progression.
