I have a series of recordings by a person who speaks with a little lateral lisp, or ‘slushy ess’. When listening with earphones, it’s tolerable. But when listening through say, an average laptop speaker, it sounds more severe.
The lisp is not that heavy, I mean ‘s’ and ‘sh’ are still distinctly different.
I’m wondering if there’s any way to enhance the ‘s’ of the entire audio through EQ, or other functions of Audacity. What kind of curve do I draw to enhance this specific sound?
There is an effect called re-essing (the opposite of de-essing) , but the bad news is it will boost every ess it encounters, even those which don’t need it like “several”.
IMO the only solution is to manually boost each individual deficient ess , which is going to be time-consuming …
