以防万一,以下是如何在pocketsphinx中持续监听关键字的示例,这比连续向谷歌发送音频更容易.

你可以有更灵活的解决方案.

import sys, os, pyaudio

from pocketsphinx import *

modeldir = "/usr/local/share/pocketsphinx/model"

# Create a decoder with certain model

config = Decoder.default_config()

config.set_string('-hmm', os.path.join(modeldir, 'hmm/en_US/hub4wsj_sc_8k'))

config.set_string('-dict', os.path.join(modeldir, 'lm/en_US/cmu07a.dic'))

config.set_string('-keyphrase', 'oh mighty computer')

config.set_float('-kws_threshold', 1e-40)

decoder = Decoder(config)

decoder.start_utt('spotting')

stream = p.open(format=pyaudio.paInt16, channels=1, rate=16000, input=True, frames_per_buffer=1024)

stream.start_stream()

while True:

buf = stream.read(1024)

decoder.process_raw(buf, False, False)

if decoder.hyp() != None and decoder.hyp().hypstr == 'oh mighty computer':

print "Detected keyword, restarting search"

decoder.end_utt()

decoder.start_utt('spotting')
