What is speech intelligibility?
What did you say?
Most of us use our voices to communicate and most of us use our hearing to listen to others. And sometimes, we just don't understand what is said.
Simply put, speech intelligibility is the business of understanding what is being said.
Sometimes hearing isn’t enough. Even for those of us who are blessed with excellent hearing, understanding what is being said can still be a challenge. This is not about language – this is about how our hearing functions and how it can be affected by factors beyond our control. Acoustics – the physical properties of the environment we are in, can play a major role in how sound ends up.. well… sounding. Background noise, psychological factors, the combined performance of the many components involved in human hearing, all play a part in how well we are able to understand what is being said – whether someone is speaking to us directly, on the phone, on a video call, in a movie theatre, on the tv… Our ears are only the beginning.
