+\subsection{Reconstruction of sounds}
+Reconstructed sounds are based on historical, internal, or paleographic evidence.
+Reconstructions by applying rules of (complex) orthography are not taken into account.
+That implies that proposals like the disharmony hypothesis proposed by 
+Houston et al. (\cites{lacadena2004}{houstonstuartrobertson1998}) do not contribute to the
+phonetic reconstruction process.
+The main reason is, that those hypotheses can not guarantee a certain reading and phonetic
+assignment, and as such are challenged by Mayanists (\cite[7]{boot2009}).
+For instance, complex vowels sometimes derived from disharmonic spellings in the script are
+accepted if and only if those vowels can be reconstructed by means of other linguistic methods.
