The Speech Transmission Index (STI) is a quantitative measure used to assess the clarity and intelligibility of speech in a given acoustic environment. It is particularly important in fields such as acoustics, audio engineering, and telecommunications. The STI provides a standardized way to evaluate how well speech can be understood in different situations, such as in classrooms, auditoriums, or public spaces.
