我正在开始一项需要将??音频转换为文本的作品.我正在使用 python的speechrecognition库.我在github上看到了如何使用它的教程.该程序并不能通过麦克风识别我的声音.

我在ubuntu 16.04上使用python 2.7.

码：

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

终端输出：

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!

之后,“说点什么！”,它继续闪烁,但我的声音无法识别.

解决方法

我无法安装PocketSphinx模块,遇到问题.
但是,如果我使用recogn_google切换recogn_sphinx,它会为我工作.

这是您修改过的代码.

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))

产量

希望这很有用.
