Sentence:  Parameters are then non-linearly re-scaled to the range of 0 to 15 to create a 4 bit acoustic vector component. Empirical non-linear scales were pre-determined for each parameter such that, over the long term, their values distributed evenly across a set of <WSD>hexadecile</WSD> bins representing the full range of the parameter. In the current system a separate non-linear scaling was established for each individual speaker, and, given the extent of the ANDOSL data used, this amounted to deriving equiprobable bins from approximately 10 minutes of spoken phonemically-rich sentence data. 
Meaning of the word marked with <WSD> tags:  Of or relating to a hexadecile.
