Voice Customization

The process of creating or modifying synthetic voices to match a user's preferences or identity, including attributes such as gender, age, pitch, breathiness, hoarseness, and speech variation. Voice customization is particularly important in accessibility for people with speech impairments who use augmentative and alternative communication (AAC) devices or text-to-speech systems, allowing them to express a vocal identity that reflects their personality, age, and gender rather than being limited to generic synthetic voices. This supports both functional communication and the social and emotional aspects of self-expression.
