+speech model basically consists of two parts:
+  * Language model: Describes all existing words and what sentences are grammatically correct. It will be created from your active scenario
+  * Acoustic model: Describes how words sound. It will be either built solely through your voice recordings (training) or with the help of a base model
+SPHINX backend" uses:
+  * PocketSphinx recognizer
+  * SphinxTrain model generation backend
+models:
+  * US English HUB4 WSJ SPHINX model. This model is part of pocketsphinx-extra where it is called \"hub4_wsj_sc_3s_8k.cd_semi_5000\".

+For small amount of data for training without context-dependent models use continuous model instead of semi-continuous one and this error will be solved.
+This warning is caused by the fact you disabled context-dependent training and used semi-continuous model. You can ignore this error until you have more data and use context-dependent training.
