A new device objectively measures the hypernasality index, quantifying nasal acoustic energy during speech. This tool offers potential for improved clinical assessment of speech disorders.

Area of Science:

  • Speech-Language Pathology
  • Acoustic Analysis
  • Medical Device Engineering

Context:

  • Hypernasality, characterized by excessive nasal resonance, affects speech clarity and intelligibility.
  • Objective assessment of hypernasality is crucial for accurate diagnosis and treatment planning.
  • Existing methods for hypernasality assessment may lack objectivity or detailed quantification.

Purpose:

  • To introduce a novel device designed for the objective measurement of the hypernasality index.
  • To detail the technical specifications and construction of the developed assessment device.
  • To explore the potential clinical applications and utility of this new device in speech diagnostics.

Summary:

  • A custom-built device has been developed to objectively quantify the hypernasality index, defined as the percentage of nasal acoustic energy relative to total phonation energy.
