+\section{Conclusion \& Future Research}
 This research 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. When applying smoothing this
-can be increased until\todo{results}.
+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.
+
+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 singing
+voice is very different from a growling voice, let alone speech.
+
+Secondly, it would be interesting if a model could be trained that could
+discriminate a singing voice for all styles of singing including growling.
+Moreover, it is possible to investigate the performance of detecting growling
+on regular singing-voice trained models and the other way around.

 \section{Discussion}
-Singing-voice detection can be seen as a crude way of
-genre-discrimination.\todo{finish}
+The dataset used is not very big. Only three albums are annotated and used
+as training data. The albums chosen do represent the ends of the spectrum and
+therefore the resulting model can be very general. However, it could also mean
+that the model is able to recognize three islands in the entire space of
+grunting. This does not seem the case since the results show that totally alien
+data also has a good performance.
 
-\todo{Novelty}
-\todo{Weaknesses}
-\todo{Dataset is not very varied but\ldots}
+The model clearly has trouble with pauses between singing.
