First exameple is simple:
import sys
import win32com.client
from win32com.client import constants
speaker = win32com.client.Dispatch("SAPI.SpVoice")
print ("Type word or phrase, then enter.")
while 1:
text_to_say = input("> ")
speaker.Speak(text_to_say)
Let's run it.The Microsoft Speech SDK to speak what you type in from the keyboard.
C:\Python373>python.exe speak_001.py
Type word or phrase, then enter.
> this is a test
The next example is more complex and uses speech recognition to create outputs.You can change this example to execute tasks.
# This is a sample code for speech recognition using the MS Speech API
from win32com.client import constants
import win32com.client
import pythoncom
"""
You will see a voice say: Started successfully
The you need to start the speech recognition tool.
After running this, then saying "One", "Two", "Three" or "Four" should
display "You said One" etc on the console.
