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.
