voice-recognize-and-run-command.sh

#!/bin/bash
# Simple script to do a command upon voice-recognition of.. a command.
# It uses pocketsphinx_continuous (which comes from debian's
#  pocketsphinx package in my case).

# For accuracy, similar phrases should be provided.
# The LAST phrase on the commandline will trigger the command
# (which is the very last thing on the command line)

# Example:
#   voice-recognize-and-command "Useless phrase one" "Useless two" "Useful phrase one" "echo command to execute"
#
# This will listen for the three phrases, and when the last one is heard,
# it'll run the echo command
