如何在 Windows 上安装 PortAudio？

Question

我想做的事：

我想在 python 程序中将语音输入转换为文本输出（使用 PyCharm IDE）， 我已经成功安装了 PyAudio，但我的程序无法运行，然后我意识到我的电脑上需要 PortAudio，但我不知道如何安装它，

我尝试过的：

我从 portaudio 官方网站下载了

pa_stable_v190700_20210406.tgz

文件，该网站还提供了其 GitHub 的链接， 我是 GitHub 的新手，我很困惑，你能一步步指导我如何将 PortAudio 安装到我的电脑上吗？

Answer 1

如果您想做的只是语音转文本，这个简单的代码应该可以工作，请先运行

pip install SpeechRecognition

，然后这个代码应该可以工作

import speech_recognition as sr

r = sr.Recognizer()

with sr.Microphone() as source:
    print("Listening...")
    audio = r.listen(source)

try:
    print("Recognizing...")
    text = r.recognize_google(audio)
    print("You said:", text)
except sr.UnknownValueError:
    print("Sorry, I could not understand your speech.")
except sr.RequestError as e:
    print("Sorry, an error occurred. {0}".format(e))

感谢您的代码。

我尝试了一下，但出现错误：

Traceback (most recent call last):
  File "C:\Users\renato\Documents\mvp_1\reconocimiento_voz.py", line 7, in <module>
    audio = r.listen(source)
            ^^^^^^^^^^^^^^^^
  File "C:\Users\renato\Documents\entornos\mvp_1\Lib\site-packages\speech_recognition\__init__.py", line 465, in listen
Listening...
    assert source.stream is not None, "Audio source must be entered before listening, see documentation for ``AudioSource``; are you using ``source`` outside of a ``with`` statement?"
           ^^^^^^^^^^^^^^^^^^^^^^^^^
AssertionError: Audio source must be entered before listening, see documentation for ``AudioSource``; are you using ``source`` outside of a ``with`` statement?

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

    with sr.Microphone() as source:

    self.stream.close()
    ^^^^^^^^^^^^^^^^^
