A Study on the Voice Security System Using Sensor Technology

A person goes through a speaking and listening process that repeats verbal, physiological, and acoustic steps for communication. Voice recognition technology utilizing a range of sensor technologies using biosignals that are measurable in these human voice activities has developed rapidly in recent years. In particular, with the development of voice recognition technology based on artificial intelligence, the related market has expanded and is being released into various services. But the problem with voice recognition still exists and there are more cases of abuse. In addition, despite advances in technology, there is a problem where the associated services are not available to patients with laryngectomy or impaired pronunciation. Therefore, this paper focuses on silent recognition, which does not require vocalization, and introduces the technologies that may be used in implementing voice security systems in the future, including sensor technology, and further discusses the need to consider issues and support policies related to privacy when using the technology.
