I have coined various phrases like “Lips Apart, Then Start”. The Voice Most Desired, Is The Voice Most Hired”… I’m particularly fond of this one…it came to me when working with a voice actor who thought he was too sibilant. I listened to him closely to determine that he was merely holding on to his S’s too long. All I had to say to him was, “Get off your lazy S!
Playback your recordings to determine if this might not apply to you as well. In most cases however, your sibilance that really annoys you, may not bother anyone else. Others may not find it to be as in your face as you think it is. We are our own worst critics. I know you’ve heard this before, and I know that by now, you have found it to be true.
So before you spend additional time editing those S’s you’ve already recorded in half, consider whether they’re worth your time and effort.
The best way to cut down on sibilance is to catch it on the front end and simply, get off your lazy S.
