Voice-related quality of life results in laryngectomies with today's speech options and expectations from the next generation of vocal assistive technologies

Objectives: To assess the voice handicap, the satisfaction with today's voice assisting methods and to identify the needs that should be addressed by new vocal assistive technologies for aphonic patients. Materials and Methods: We conducted a prospective study on two samples of patients with total laryngectomy and submitted to speech therapy. Voice Handicap Index (VHI) questionnaires and qualitative (focus-groups) and quantitative (online surveys) methods were used. Results: Analysis of the VHI total revealed that the esophageal and electrolarynx speakers had a moderate voice handicap, while tracheoesophageal speakers and patients without vocal rehabilitation had a severe handicap. Interview and survey data indicated that these patients have many needs which are unmet by available rehabilitation methods. Conclusions: These results point out the necessity to improve current vocal assistive methods and to develop better technologies that could increase the quality of life of this patients.
