语音识别在ubuntu中不起作用

Question

I am starting a work which needs to convert audio into text. I am using the speechrecognition library of python. I saw a tutorial on github on how to use it. The program is not bale to recognise my voice through microphone.

I am using python 2.7 on ubuntu 16.04.

Code:

import speech_recognition as sr

# obtain audio from the microphone
r = sr.Recognizer()
with sr.Microphone() as source:
    print("Say something!")
    r.adjust_for_ambient_noise(source)
    audio = r.listen(source)

# recognize speech using Sphinx
try:
    print("Sphinx thinks you said " + r.recognize_sphinx(audio))
except sr.UnknownValueError:
    print("Sphinx could not understand audio")
except sr.RequestError as e:
    print("Sphinx error; {0}".format(e))

github code link

Output on terminal:

shivam@shivam-HP-Pavilion-15-Notebook-PC:~/Python/audio$ python temp.py
ALSA lib pcm_dsnoop.c:606:(snd_pcm_dsnoop_open) unable to open slave
ALSA lib pcm_dmix.c:1029:(snd_pcm_dmix_open) unable to open slave
ALSA lib pcm_dmix.c:1029:(snd_pcm_dmix_open) unable to open slave
Say something!

After, "Say something!", it keeps on blinking but my voice is not recognised.

I couldn't get PocketSphinx module installed , running into issues. But if I switch recognize_sphinx with recognize_google , its working for me.

Here is your modified code.

import speech_recognition as sr

# obtain audio from the microphone
r = sr.Recognizer()
with sr.Microphone() as source:
    print("Say something!")
    r.adjust_for_ambient_noise(source)
    audio = r.listen(source)

# recognize speech using Sphinx
try:
    #print("Sphinx thinks you said " + r.recognize_sphinx(audio))
    print("Sphinx thinks you said " + r.recognize_google(audio))
except sr.UnknownValueError:
    print("Sphinx could not understand audio")
except sr.RequestError as e:
    print("Sphinx error; {0}".format(e))

Output

Hope this is useful.
