import speech_recognition as sr
import datetime
import webbrowser
import speech_recognition as sr
import pytesseract
from PIL import Image
from pytesseract import image_to_string
pytesseract.pytesseract.tesseract_cmd = 'C:\\Program Files\\Tesseract-OCR\\tesseract.exe'




def say(talk):
    engine.say(talk)
    engine.runAndWait()

say("Hello, Let's Start!")


record = sr.Recognizer()
try:

    with sr.Microphone(device_index=1) as source:
        print("Speak Now Please!........")
        audio = record.listen(source)
        result = record.recognize_google(audio)
        result = result.lower()
        print(result)


        if result == "write file":
            str_file = image_to_string(Image.open('Images/photo.png'))
            file = open("text_from.txt", "w")
            file.write(str_file)
            file.close()



        elif result == "read file":
            file = open("text_from.txt", "rt")
            for line in file:
                print(line)
            file.close()

        elif result == "exit":
            print("exit")
