VHI (Voice Handicap Index)

The Voice Handicap Index (VHI) is a questionnaire used to assess how a voice disorder affects a person’s daily life. It measures the emotional, functional, and physical impact of voice problems by asking about issues like difficulty speaking, social interactions, and emotional well-being related to voice concerns. The higher the VHI score, the greater the perceived handicap or impact on quality of life. It helps clinicians understand the severity of a voice disorder from the patient's perspective and guides treatment planning. The VHI is a valuable tool for monitoring progress over time.
