speech_recognition模塊卡在“說些什么”中-python

Question

我正在嘗試用於語音識別的python腳本，我已經在我的環境中安裝了所需的pyaudio和SpeechRecognition模塊。

該程序運行良好，直到昨天，但是現在被困在“說些什么”了。 下面是我的代碼。

import speech_recognition as sr
print "say something1"
r = sr.Recognizer()
print "say something2"
with sr.Microphone() as source:                # use the default microphone as the audio source
    print "say something3"
    audio = r.listen(source,timeout=3)                   # listen for the first phrase and extract it into audio data

print "say something"
try:
    print("You said " + r.recognize(audio))    # recognize speech using Google Speech Recognition
except LookupError:                            # speech is unintelligible
    print("Could not understand audio")

控制台o / p：-

say something1
say something2

ALSA lib pcm_dmix.c:1029:(snd_pcm_dmix_open) unable to open slave
say something3

不重復/已轉為：- 語音識別python代碼不起作用

Answer 1

也許這可以解決您的問題。

print "say something2"
with sr.Microphone() as source:                # use the default microphone as the audio source
    r.adjust_for_ambient_noise(source)  # here
    print "say something3"
    audio = r.listen(source,timeout=3)

最后的解決方案對我有用。 希望你能做同樣的工作

Answer 2

我也遇到了同樣的問題，我最終安裝了jack2d和Pulseaudio，什么也沒有。

那是問題，然后我通過運行卸載了jack2d

sudo apt-get remove --auto-remove jack

然后重新啟動系統，然后運行

jack_control  stop

然后，這會將語音輸入提供給pulse-aduio。

運行程序時，控制台應打印

ALSA lib pcm_dsnoop.c:606:(snd_pcm_dsnoop_open) unable to open slave
ALSA lib pcm.c:2266:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.rear
ALSA lib pcm.c:2266:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.center_lfe
ALSA lib pcm.c:2266:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.side
ALSA lib pcm_route.c:867:(find_matching_chmap) Found no matching channel map
ALSA lib pcm_route.c:867:(find_matching_chmap) Found no matching channel map
ALSA lib pcm_route.c:867:(find_matching_chmap) Found no matching channel map

jack server is not running or cannot be started
JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1, skipping unlock
JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1, skipping unlock

最后一行指出Jack已停止並且語音輸入正被重定向為pulse。

實際發生的是，音頻resoruce（mic）僅被引導到插孔或脈沖，所以我卸載了jack

現在我的程序運行正常

Answer 3

當我嘗試您的代碼時，出現以下attribute錯誤。

AttributeError: 'Recognizer' object has no attribute 'recognize'

看完文檔后 ， Recognizer類似乎沒有方法可recognize 。 您將需要使用recognize類提供的幾種recognize_*方法之一。
看來您想使用recognize_google ，所以當我從

print("You said " + r.recognize(audio))

至

print("You said " + r.recognize_google(audio))

該代碼為我工作。

我說了“你好”，這在下面得到了認可。

You said hello

希望這可以幫助。

Answer 4

我也有這個問題，並且不斷變化

audio = r.listen(source,timeout=3)

至

audio = r.listen(source,timeout=3, phrase_time_limit=3)

為我解決了。
