 ### Speech distribution
 
-Speech distributions used to generate the simulated "null-hypothesis" corpora are fitted against the training data using Gamma distributions. The code used to fit these distributions is found in ``code/models/speech_distribution``.

+Speech distributions used to generate the simulated "null-hypothesis" corpora are fitted against the training data using Gamma distributions. The simplest models rely on a MLE fit of a global distribution based on all corpora, using the code available in ``code/models/speech_distribution``.

+The match between the training data and the Gamma parametrization can be observed in various plots in ``output``. See below for the Key child (vocalizations for 9 hours of data from 9am to 6pm):

+We also provide a model with a fully bayesian fit of the distributions of the true amount of speech among speakers. This allows to derive corpus-level distributions and to capture the uncertainty due to the limited amount of "ground truth" annotations. Here are, for instance, the posterior speech rate distributions (in voc/h) derived for Vanuatu:
