currently following command starts pocketsphinx , waits volume hit specific threshhold microphone, starts recording, , when volume drops below threshhold start processing recorded audio , output hello if word detected. pocketsphinx_continuous -inmic yes -keyphrase "hello" -kws_threshold 1e-30 due environments can tad noisy, waiting volume threshhold drop can take longer expected. there way pocketsphinx output recognizable words they're being spoken without need of waiting silence? overall if have significant noise, it's better cancel hardware somehow. microphone array source separation, directed beam microphone , on should reduce noise significantly. not idea rely on pocketsphinx deal noise, it's not designed that. if want immediate reaction on spotting, you'd better use pocketsphinx through api, not pocketsphinx_continuous, simple example in python want example: import sys, os, pyaudio pocketsphinx.pocketsphinx import * sphinxbase.sphinx...
