Error in pycharm 'say�����' is not recognized as an internal or external command, operable program or batch file.?

Question

Python

Wrote a mini program that should take text and say it. But when I run it, I get an error
Code

import speech_recognition as sr
import os
import sys
import webbrowser
import subprocess

def talk(words):
    print(words)
    os.system("say" + words)

talk("Слово")

Here is the error

'say""�����' is not recognized as an internal or external command,
operable program or batch file.
