python - 如何使用 macOS 上的 Speech_recognition 模块修复“OSError:[Errno -9986] 内部 PortAudio 错误”?
问题描述
我试图在 macOS 上使用 python 构建语音到文本识别(请不要在此处发布针对 Windows 设备的建议)。
我正在尝试使用 SpeechRecognition 示例代码并开发我的应用程序,但每次尝试运行代码时都会出现以下错误:
OSError: [Errno -9986] 内部端口音频错误
我已经安装了 PortAudio
brew install portaudio
和 PyAudio 以及
pip3 install pyaudio
.
这是示例代码:
import speech_recognition as sr
# obtain audio from the microphone
r = sr.Recognizer()
with sr.Microphone() as source:
print("Say something!")
audio = r.listen(source)
# recognize speech using Google Speech Recognition
try:
# for testing purposes, we're just using the default API key
# to use another API key, use `r.recognize_google(audio, key="GOOGLE_SPEECH_RECOGNITION_API_KEY")`
# instead of `r.recognize_google(audio)`
print("Google Speech Recognition thinks you said " + r.recognize_google(audio))
except sr.UnknownValueError:
print("Google Speech Recognition could not understand audio")
except sr.RequestError as e:
print("Could not request results from Google Speech Recognition service; {0}".format(e))
这是错误消息的回溯:

OSError: [Errno -9986] Internal PortAudio error
解决方案
尝试以下操作:
- brew卸载portaudio
- 酿造安装 portaudio --HEAD
这对我有用。我从这个 Github 问题中得到它:https ://github.com/spatialaudio/python-sounddevice/issues/299
