Question

我忙着做语音识别代码，我有这样的：

from pocketsphinx.pocketsphinx import * 
from sphinxbase.sphinxbase import * 

import os 
import pyaudio 
import wave 
import audioop 
from collections import deque 
import time 
import math 

class SpeechDetector: 
    def __init__(self): 
     self.CHUNK = 1024 
     self.FORMAT = pyaudio.paInt16 
     self.CHANNELS = 1 
     self.RATE = 16000 

     self.SILENCE_LIMIT = 1 
     self.PREV_AUDIO = 0.5 

     self.THRESHOLD = 4500 
     self.num_phrases = -1 

     MODELDIR = "../../tools/pocketsphinx/model" 
     DATADIR = "../../tools/pocketsphinx/test/data" 

     config = 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')) 

     self.decoder = Decoder(config) 

    def setup_mic(self, num_samples=50): 
     print "Getting intensity values from mic." 
     p = pyaudio.PyAudio() 
     stream = p.open(format=self.FORMAT, 
         channels=self.CHANNELS, 
         rate=self.RATE, 
         input=True, 
         frames_per_buffer=self.CHUNK) 

     values = [math.sqrt(abs(audioop.avg(stream.read(self.CHUNK), 4))) 
      for x in range(num_samples)] 
      values = sorted(values, reverse=True) 
     r = sum(values[:int(num_samples * 0.2)])/int(num_samples * 0.2) 
     print " Finished " 
     print " Average audio intensity is ", r 
     stream.close() 
     p.terminate() 

     if r < 3000: 
      self.THRESHOLD = 3500 
     else: 
      self.THRESHOLD = r + 100 

    def save_speech(self, data, p): 

     filename = 'output_'+str(int(time.time())) 
     data = ''.join(data) 
     wf = wave.open(filename + '.wav', 'wb') 
     wf.setnchannels(1) 
     wf.setsampwidth(p.get_sample_size(pyaudio.paInt16)) 
     wf.setframerate(16000) 
     wf.writeframes(data) 
     wf.close() 
     return filename + '.wav' 

def decode_phrase(self, wav_file): 
    self.decoder.start_utt() 
    stream = open(wav_file, "rb") 
    while True: 
     buf = stream.read(1024) 
     if buf: 
      self.decoder.process_raw(buf, False, False) 
      self.decoder.end_utt() 

      words = [] 
      [words.append(seg.word) for seg in self.decoder.seg()] 
      return words 

def run(self): 
    self.setup_mic() 

p = pyaudio.PyAudio() 
stream = p.open(format=self.FORMAT, 
       channels=self.CHANNELS, 
       rate=self.RATE, 
       input=True, 
       frames_per_buffer=self.CHUNK) 
print "* Mic set up and listening. " 

audio2send = [] 
cur_data = '' 
rel = self.RATE/self.CHUNK 
slid_win = deque(maxlen=self.SILENCE_LIMIT * rel) 
prev_audio = deque(maxlen=self.PREV_AUDIO * rel) 
started = False 

while True: 
    cur_data = stream.read(self.CHUNK) 
    slid_win.append(math.sqrt(abs(audioop.avg(cur_data, 4)))) 

    if sum([x > self.THRESHOLD for x in slid_win]) > 0: 
     if started == False: 
      print "Starting recording of phrase" 
      started = True 
      audio2send.append(cur_data) 
     elif started: 
      print "Finished recording, decoding phrase" 
      filename = self.save_speech(list(prev_audio) + audio2send, p) 
      r = self.decode_phrase(filename) 
      print "DETECTED: ", r 
      os.remove(filename) 

stream.close() 
p.terminate() 

if __name__ == "__main__": 
    sd = SpeechDetector() 
    sd.run() 

但我每次运行它的时候说：导入错误：没有名为pyaudio的模块。

然后我去端和我做的点子安装pyaudio 但随后它表明这一点：

#include "portaudio.h" 

     ^
1 error generated. 
error: command '/usr/bin/clang' failed with exit status 1 

我使用的是MacBook和MacOS版本山脉从10.12.5 2011年我看着每堆溢出页面，但没有与我合作。请帮帮我！

安装pyaudio之前需要安装portaudio。用自制

安装portaudio从pyaudio网站

Apple Mac OS X Use Homebrew to install the prerequisite portaudio library, then install PyAudio using pip:

brew install portaudio 
pip install pyaudio 

Notes:

If not already installed, download Homebrew. pip will download the PyAudio source and build it for your version of Python. Homebrew and building PyAudio also require installing the Command Line Tools for Xcode (more information).
