我最近在python中使用口袋狮身人面像.我已经成功地通过以下示例来识别录制的wav.
#!/usr/bin/env python
import sys,os
def decodeSpeech(hmmd,lmdir,dictp,wavfile):
"""
Decodes a speech file
"""
try:
import pocketsphinx as ps
import sphinxbase
except:
print """Pocket sphinx and sphixbase is not installed
in your system. Please install it with package manager.
"""
speechRec = ps.Decoder(hmm = hmmd, lm = lmdir, dict = dictp)
wavFile = file(wavfile,'rb')
wavFile.seek(44)
speechRec.decode_raw(wavFile)
result = speechRec.get_hyp()
return result[0]
if __name__ == "__main__":
hmdir = "/home/jaganadhg/Desktop/Docs_New/kgisl/model/hmm/wsj1"
lmd = "/home/jaganadhg/Desktop/Docs_New/kgisl/model/lm/wsj/wlist5o.3e-7.vp.tg.lm.DMP"
dictd = "/home/jaganadhg/Desktop/Docs_New/kgisl/model/lm/wsj/wlist5o.dic"
wavfile = "/home/jaganadhg/Desktop/Docs_New/kgisl/sa1.wav"
recognised = decodeSpeech(hmdir,lmd,dictd,wavfile)
print …我有在树莓派 B++ 上运行的 python 代码，它使用 sounddevice 库，可让您使用 python 播放和录制声音。我已经成功安装了模块。我可以通过 python 命令行确认并输入 import sounddevice 因为 sd 可以正常工作，没有错误。我还通过在 python 命令行中输入 help ('modules') 进行确认，并且出现了 sounddevice 模块。仅当我在独立的 python 程序中运行此代码时，才会出现 ImportError: No module name sounddevice 。
希望有人可以提供帮助。
这是包含的代码：
将声音设备导入为 SD
错误：
导入错误：没有模块名称 sounddevice
我有一个连接到树莓派3的USB麦克风和扬声器适配器.我已经在alsamixer上设置了所有内容.我还在主目录中设置了pcm.!default sysdefault:0in文件.asoundrc,它将usb音频适配器设置为默认音频卡.
我跑了:aplay -l,输出是:
