Problem Statement

  • Electrolarynx devices suffer from reduced intelligibility, monotonous speech, and unnatural sound quality, impacting communication effectiveness for laryngectomy patients.
  • Current electrolarynx solutions lack fine control over pitch and loudness variation, limiting the user’s ability to express emotions and nuances in speech.
  • Existing electrolarynx devices often require continuous manual activation, causing inconvenience and restricting the user’s mobility and activities.

Technology

  • The present invention relates to a speech aid device and more particularly relates to a biomechanical electrolarynx device for voice rehabilitation of laryngectomees after laryngectomy
  • The present invention aims to create a cost-effective, lightweight, and user-friendly electrolarynx system for voice rehabilitation of laryngectomy patients.
  • It features a mechanical electrolarynx device comprising a transducer powered by an electric motor, converting electrical energy into mechanical vibrations to stimulate the patient’s vocal cords.
  • Through a custom-designed transducer mechanism, vibrations are transmitted to the patient’s throat, enabling speech production with minimal modulation from tongue and mouth movements.
