 \section{Conclusion}
 This study shows that existing techniques for singing-voice detection
-designed for regular singing-voices also work respectably on extreme singing
-styles like grunting. With a standard \gls{ANN} classifier using \gls{MFCC}
-features a performance of $85\%$ can be achieved which is similar to the same
-techniques on regular singing. This means that it might be suitable as a
-pre-processing step for lyrics forced alignment. The model performs pretty well
-on alien data that uses similar singing techniques as the training set.
-However, the model does not cope very well with different singing techniques or
-with data that contains a lot of atmospheric noise and accompaniment.

-From the results we conclude that the model generalizes well over the trainings
-set, even with little hidden nodes. The models with 3 or 5 hidden nodes score a
-little worse than their bigger brothers but there is hardly any difference
-between the performance of a model with 8 or 13 nodes. Moreover, contrary than
-expected the window size does not seem to be doing much in the performance.
+To determine whether the model generalizes, alien data has been offered to the
+model to see how it performs. It was shown that for similar singing styles the
+models perform similar. The alien data offered containing different singing
+styles, atmospheric noise and accompaniment is classified less good.

 Future interesting research includes doing the actual forced alignment. This
 probably requires entirely different models. The models used for real speech
 are probably not suitable because the acoustic properties of a regular
