Removing a lisp in audio

Ok first off I am not an audio guy I'm more experienced with camera work and video editing. Recently I was doing a video shoot talking head style. Half way through the shoot the talent says to me "by the way I know you can't here it now but when you play back the recording you'll here I have a lisp". He told be that audio guys usually remove with some eq. Well low and behold he was right there is a lisp in the audio. I've tried searching the internet which has been little to no help and I've tried messing with audio filters in Final Cut (which I'm sure aren't the best). For audio I only have access to final cut and soundtrack and I suppose Garageband if thats of any help. If any one has any experience in this area I'd greatly appreciate it.
 
A de-esser is the first line of defense. It's a frequency-specific compressor. Start around 6000Hz and adjust from there until you eliminate the problem frequency band.
 
A de-esser is a plug-in in case you didn't gather that. Here's a list of free plug-ins I just found, and there is a de-esser there.

I wouldn't recommend using plugs too much in FCP. For some reason FCP is lame with plugs in that you get all these numeric sliders, rather than the GUI designed by the companies that made the plug-ins. In most any other audio app you will see the GUI (Graphical User Interface) and be able to adjust the plug with much more ease, and make adjustments on the fly. FCP often stops playback when you make an adjustment.
 
Thanks for the help, I've been messing around the de-esser in both final cut and sound track pro and not having any luck getting rid of the lisp. Are there any tutorial any ones knows of that would teach you to use the de-esser.
 
You will never get rid of a lisp...you might be able to reduce the sibilance a bit, but that's the most you could hope for. Best of luck.
 
Yeth if a perthon has a sthpeech impediment like a lithp, iths really hard to minimithe.

You could grab an "ess" sound from somewhere else and try to surgically replace it. I've dealt with this a couple of times and there is just nothing to do. Possibly if you extend the range of the de-esser to the max, so you can hear it happening, then pull back until it is usable. Otherwise get a graphic EX up and pull out the range with the lisp. If it's a client that provided person with the lisp to do the speaking, then I say they get what they get. This should have been nipped in the bud, and a person with basic speaking ability should be used.
 
I was just thinking about that. Since you were aware he was going to have a lisp (he told you), could you force about 10 different "sss" sounds and add them in post? It would be a pain in the butt, but possibly worth it in the long run.

I remember doing a short video for a man at church a few years back, and we were interviewing her daughter. "She's a great public speaker," they told me. I believed them. Apparently she WAS a great public speaker until she had throat surgery and had a hole in her throat. Now, every time she breathed, it was a loud "HHHHRRRRNNNNNXXXX" that was well above the levels of anything else recorded. I spent so much time cutting that out because it would have sounded TERRIBLE over the speakers at church. No one had any idea she even had a hole in her throat (standard definition made it seem like a shadow).
 
Thanks again, I was able to contact someone who's worked with this guys audio before. Still waiting to here back. His lisp was completely unnoticeable during the shoot but he knew that it would show up in the recording, weird. Anyway it was the client's choice so I'll do my best to fix it but in the end it was their choice.
