Error not finding Path.

In a Python module

from google_speech import Speech

This URL https://pypi.org/project/google-speech/
,
First install the above with pip, then SoX website Installed Sox.

But with Jupyter

from google_speech import Speech

-------------------------------------------- -------------------------------

Will be returned.
However, if you enter Sox in CMD, the program starts, so Sox itself is installed safely.

I tried changing the path, but it doesn't work.
Sox.exe

C: \ Users \ tsst1 \ AppData \ Roaming \ Microsoft \ Windows \ Start Menu \ Programs \ sox-14.4.2

It is in.

I tried adding the above path to Control Panel->Preferences->Path, but it also gives an error.
Other Path
C: \ Users \ tsst1 \ AppData \ Roaming \ Microsoft \ Windows \ Start Menu \ Programs \sox-14.4.2-win32.exe

C: \ Users \ tsst1 \ AppData \ Roaming \ Microsoft \ Windows \ Start Menu \ Programs \sox-14-4-2

I changed it to

etc., but it doesn't work
Is there any solution?
