Um. And  we think that  with this approach perhaps  we could reduce the number of outputs of the neural network. Um , So , get simpler networks , because we still have the features. So we have um  come up with um  different kind of  broad phonetic categories. And we have  Basically we have three  types of broad phonetic classes. Well , something using place of articulation which  which leads to  nine , I think ,  broad classes. Uh , another which is based on manner , which is  is also something like nine classes. And then ,  something that combine both , and we have  twenty f  twenty - five ?
Twenty - seven.
Twenty - seven broad classes. So like , uh , oh , I don't know , like back vowels , front vowels.
So what you do  um I just wanna understand
