The Application of Artificial Intelligence to Assist People with Hearing Impairments: An Overview of Existing Solutions

Hearing impairment is a very serious problem, because it negatively affects communication between people and it also impacts their overall quality of life.Therefore, it is crucial to develop methods to help people with this problem.Although there are many hearing aids with advanced features, many analyses show that more than half of users are not satisfied.The application of Artificial Intelligence (AI) and especially Deep Learning (DL) are increasingly being mentioned as a solution.These methodologies are of recent date.Therefore, this paper provides an overview of the most important methods that use AI approaches to enable personalization and individualization of hearing aids.This primarily refers to Automatic Speech Recognition (ASR) methods, Sign Language Recognition methods (SLR), Intelligent methods for personalized hearing aids, Artificial intelligence methods in bone conduction hearing systems and Methods based on the Internet of Things (IoT).We have demonstrated the existing methods capabilities and challenges, but directions of future development are also particularly emphasized.
