pocketsphinx-python
===================

[![Build Status](https://travis-ci.org/bambocher/pocketsphinx-python.svg?branch=master)](https://travis-ci.org/bambocher/pocketsphinx-python)

Python interface to CMU SphinxBase and PocketSphinx libraries created with SWIG.
Pocketsphinx packages include python support, however, it is based on Automake and
not well supported on Windows.

This package provides module created with Python distutils setup and can be more
portable.

DATADIR = "pocketsphinx/test/data"

# Create a decoder with certain model
config = Decoder.default_config()
config.set_string('-hmm', path.join(MODELDIR, 'en-us/en-us'))
config.set_string('-lm', path.join(MODELDIR, 'en-us/en-us.lm.bin'))
config.set_string('-dict', path.join(MODELDIR, 'en-us/cmudict-en-us.dict'))
decoder = Decoder(config)

# Decode streaming data.
decoder = Decoder(config)
decoder.start_utt()
stream = open(path.join(DATADIR, 'goforward.raw'), 'rb')
while True:
  buf = stream.read(1024)
  if buf:
    decoder.process_raw(buf, False, False)
  else:
    break
