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.
