pocketsphinx 0.1.0

Python interface to CMU Sphinxbase and Pocketsphinx libraries

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. Pocketsphinx is part of the CMU Sphinx Open Source Toolkit For Speech Recognition.

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

Basic usage

#!/usr/bin/env python
import os

import sphinxbase as sb
import pocketsphinx as ps

MODELDIR = 'deps/pocketsphinx/model'
DATADIR = 'deps/pocketsphinx/test/data'

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

# Decode streaming data.
decoder.start_utt()
stream = open(os.path.join(DATADIR, 'goforward.raw'), 'rb')
while True:
    buf = stream.read(1024)
    if buf:
        decoder.process_raw(buf, False, False)
    else:
        break
decoder.end_utt()
stream.close()
print('Best hypothesis segments:', [seg.word for seg in decoder.seg()])
