Question

[编辑] PyAudio无法正常工作，该程序根本不进行任何语音识别。

我正在虚拟机上运行Ubuntu而且我制作了一个简短的脚本。它使用SpeechRecognition 3.5.0来检测用户说的内容。我安装了pyaudio，但是当我运行脚本时，我得到一个很长的错误。我在笔记本电脑上使用内置麦克风。

import wolframalpha
import os
from gtts import gTTS
import speech_recognition as sr
r = sr.Recognizer()
with sr.Microphone() as source:              
    audio = r.listen(source) 
print("You said " + r.recognize(audio)) 
app_id = ("H34HDS-SDFJKOEER2")
client = wolframalpha.Client(app_id)
while app_id == "H34HDS-SDFJKOEER2":
    input = raw_input("Question: ")
    res = client.query(input)
    answer = next(res.results).text
    tts = gTTS(text=answer, lang='en')
    tts.save("hello.mp3")
    os.system("mpg321 hello.mp3")

我得到的错误是：

我从他们的页面提供了答案。基本上你没有运行插孔音频服务器。作为一个不得不使用Linux音频的人，我可以告诉你这可能是一种痛苦。

来自https://pypi.python.org/pypi/SpeechRecognition/

在Ubuntu / Debian上，我收到“杰克服务器未运行或无法启动”或“无法锁定[...]字节存储区（无法分配内存）”等错误。

Linux音频堆栈非常善变。有一些事情可能导致这些问题。

首先，确保安装了JACK - 安装它，运行sudo apt-get install multimedia-jack

然后，您需要正确配置JACK守护程序以避免“无法分配内存”错误。运行sudo dpkg-reconfigure -p high jackd2并选择“是”来执行此操作。

现在，您需要确保当前用户位于音频组中。您可以通过运行sudo adduser $（whoami）audio将您当前的用户添加到此论坛。

不幸的是，这些更改将要求您在生效之前重新启动。

重新启动后，运行pulseaudio --kill，然后执行jack_control start，修复“jack服务器未运行或无法启动”错误
