Deploying a high-quality open-source Persian TTS system presents several challenges and ethical considerations. One significant challenge is ensuring the accuracy and reliability of the synthesized speech. Variability in pronunciation, intonation, and emotional expression can affect the naturalness of the output, particularly for users with specific accessibility needs, such as those with visual impairments. Continuous evaluation and improvement of the TTS model are necessary to address these concerns.
Ethically, the use of a TTS system raises issues related to voice impersonation and privacy. The potential for misuse, such as creating deceptive audio that mimics a person's voice, necessitates the implementation of safeguards to prevent malicious applications. Anonymization techniques should be considered to protect the identities of the speakers in the dataset, ensuring that their voices cannot be easily replicated without consent.
Moreover, the accessibility of the TTS system must be balanced with the need for responsible usage. Clear guidelines should be established regarding the ethical use of the technology, particularly in sensitive contexts such as education, healthcare, and public services. Ensuring that the TTS system is used to empower users rather than exploit them is paramount.
Finally, there is a need for ongoing community engagement to address the evolving needs of users. Feedback from the visually impaired community and other stakeholders can guide the development of features that enhance usability and accessibility, ensuring that the TTS system serves its intended purpose effectively.
