What are Speech Therapy Calculators?
Speech therapy calculators are specialized clinical tools that assist speech-language pathologists in assessment and measurement of human communication disorders, voice, hearing, language, speech, and swallowing. They enable application of scales such as Voice Handicap Index (VHI) for vocal assessment, dysphagia assessment protocols, stuttering severity scales, and language screening instruments. Based on nationally and internationally validated protocols, evidence in speech-language sciences, and professional society guidelines, these calculators standardize assessments, quantify symptoms, and facilitate monitoring of therapeutic evolution in speech-language rehabilitation.
When to Use These Tools
- Vocal quality assessment through VHI
- Classification of dysphagia severity in neurological patients
- Assessment of stuttering severity in children and adults
- Screening for language delay in child development
- Monitoring speech-language therapeutic evolution
- Objective documentation of rehabilitation outcomes

Frequently Asked Questions
What is Voice Handicap Index (VHI)?
VHI is a 30-item questionnaire that assesses self-perception of voice problem impact in three domains: functional, physical, and emotional. Score ranges from 0-120. Values >60 indicate severe vocal handicap. It is used for screening, voice therapy indication, and evolution monitoring.
How to safely assess dysphagia?
Dysphagia assessment should be multiprofessional. Use validated protocols such as GUSS, FOIS, or penetration/aspiration scales. Clinical assessment is fundamental, but videofluoroscopic swallowing study (VFSS) or fiberoptic endoscopic evaluation of swallowing (FEES) are gold standard to confirm aspiration and guide safe rehabilitation.
Do calculators replace speech-language assessment?
No. Calculators and scales are complementary tools that standardize part of the assessment, but do not replace detailed anamnesis, qualitative clinical observation, specific tests, and professional judgment of the speech-language pathologist. They are useful for quantifying and monitoring, not for diagnosing in isolation.
