How to solve pip installation command - python-3.x

Question

I have problem with the python speech recognization problem and audio libraries
This is on the windows system
import speach_recognition as sr
r =sr.Recognizer()
with sr.Microphone() as source:
print("Speak Anything")
audio = r.listen(source)
try:
text = r.recognize_google(audio)
print('you said : {}'.format(text))
except:
print('sorry could not recognized voice')

Answer 1

As your error indicates:
Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": https://visualstudio.microsoft.com/downloads/
You need to install MS Visual C++ 14.0 compiler so that the C++ dependencies can be built (detailed instruction here).
Another option is (following advice from this answer) to use an unofficial library of compiled Windows dependencies for Python packages from Unofficial Windows Binaries for Python Extension Packages.
