But it  I  I  I  I think it will be important. Because eh people eh eh , different groups eh has eh experience with this eh kind of problem. Is  eh is not easy eh to  to solve , because if you  I  I   I have seen the  the  the speech file from eh PDA , and s some parts is  very difficult because you  you don't see the spectrum  the spectrogram.
Right. Yeah , they 're totally hidden.
Is very difficult to apply eh , eh a parameter to detect change when you don't see.
Yeah. Yeah. Well , that  that  that 's another reason why very simple features , things like energy , and things  things like harmonicity , and  residual energy are uh , yeah are  are better to use than very complex ones because they 'll be more reliable.
