As an alternative communication method for laryngectomy patients， we introduced a novel voice synthesis smartphone application， referred to as the “speech synthesis app,” alongside conventional alternative speech options. This app employs artificial intelligence technology to generate artificial voices that closely resemble users’ own voices based on recorded samples. While previous research has indicated high satisfaction rates with the speech synthesis app itself， there have been instances where the potential of alternative voices remained underutilized. To investigate the degree of satisfaction with alternative speech via synthetic voices among laryngectomy patients， we conducted a comprehensive assessment utilizing both quantitative and qualitative analyses. The Self-Evaluation of Communication Experiences after Laryngectomy (SECEL)， designed to evaluate post-laryngectomy communication， revealed a decline in scores related to speech environments. In addition， through the interview survey， we identified significant needs from both the patients and their families， although these preferences did not always align perfectly with the capabilities of the speech synthesis app. These findings underscore the importance of providing support for patients’ acceptance of this innovative technology， ensuring that it is tailored to individual preferences and convenience. By addressing these challenges， we can further enhance the satisfaction and effectiveness of synthetic voices as an alternative means of communication for patients undergoing laryngectomy．
