What are Speech Therapy Calculators?
Speech therapy calculators are specialized clinical tools that assist speech-language pathologists in the assessment and measurement of human communication disorders, voice, hearing, language, speech, and swallowing. They enable the application of scales such as the 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
- Dysphagia severity classification in neurological patients
- Stuttering severity assessment 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 the Voice Handicap Index (VHI)?
VHI is a 30-item questionnaire that assesses self-perception of the impact of vocal problems in three domains: functional, physical, and emotional. Scores range from 0-120. Values >60 indicate severe vocal handicap. It is used for screening, indication of vocal therapy, and monitoring evolution.
How to assess dysphagia safely?
Dysphagia assessment should be multiprofessional. Use validated protocols like GUSS, FOIS, or penetration/aspiration scales. Clinical assessment is fundamental, but fiberoptic endoscopic evaluation of swallowing (FEES) or videofluoroscopy are gold standards to confirm aspiration and guide safe rehabilitation.
Do calculators replace speech therapy assessment?
No. Calculators and scales are complementary tools that standardize part of the assessment, but do not replace detailed history, qualitative clinical observation, specific tests, and the professional judgment of the speech therapist. They are useful to quantify and monitor, not to diagnose in isolation.
