Download the pre-trained model (1.8GB):

wget https://github.com/mozilla/DeepSpeech/releases/download/v0.9.3/deepspeech-0.9.3-models.pbmm
wget https://github.com/mozilla/DeepSpeech/releases/download/v0.9.3/deepspeech-0.9.3-models.scorer

Edit references to models path if necessary:

let modelPath = './models/deepspeech-0.9.3-models.pbmm';
let scorerPath = './models/deepspeech-0.9.3-models.scorer';

Install Sox (for .wav file loading):

brew install sox

Download test audio files:
