Description

We repeatedly get questions in the forum about how to decode just one file. It would be good if we had a documentation page or sub-page about this, that would describe the various steps required to do this, in the context of one of the example scripts.

Research direction
Examine the existing Kaldi documentation and forums to understand common questions about decoding a single file. Look at example scripts like egs/wsj/s5/run.sh for the decoding pipeline. Identify the necessary steps: feature extraction (compute mfcc feats), decoding (gmm latgen faster), and possibly lattice tools. Write a concise guide with command examples and explanations.
