Python語音識別錯誤ALSA

Question

[編輯] PyAudio不工作，程序根本不做任何語音識別。

我在虛擬機上運行Ubuntu，並製作了一個簡短腳本。它使用SpeechRecognition 3.5.0來檢測用戶說什麼。我安裝了pyaudio，但是當我運行這個腳本時，我得到一個很長的錯誤。我在筆記本電腦上使用內置麥克風。

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") 

是我得到的錯誤是：

我提供了從他們的頁面的答案。基本上你沒有插孔音頻服務器運行。作爲一個不得不使用Linux音頻的人，我可以告訴你這可能是一種痛苦。

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

在Ubuntu/Debian的，我得到這樣的「傑克服務器沒有運行或無法啓動」或錯誤「無法鎖定[...]字節的存儲區（無法分配內存）」。

Linux音頻棧非常易變。有幾件事會導致這些問題。

首先，確保JACK安裝 - 安裝它，執行sudo apt-get的安裝多媒體插孔

那麼你將要正確配置JACK守護進程，以避免「無法分配內存」錯誤。運行sudo dpkg-reconfigure -p high jackd2並選擇「是」來執行此操作。

現在，您將需要確保您的當前用戶位於音頻組中。您可以通過運行sudo adduser $（whoami）音頻將當前用戶添加到該組。

不幸的是，這些更改將需要您重新啓動才能生效。

重啓後，運行的PulseAudio --kill，其次是jack_control啓動，修復「傑克服務器沒有運行或無法啓動」錯誤
