Create a Python voice reminder app

Here’s a Python script for a simple voice reminder app. It lets you:

• Set a reminder time

• Speak a reminder message

• The app will notify you by speaking the reminder at the set time

It uses speech_recognition for voice input, pyttsx3 for text-to-speech, and datetime to track time.

import speech_recognition as sr
import pyttsx3
import datetime
import time

# Initialize speech engine
engine = pyttsx3.init()
engine.setProperty('rate', 150)  # Speech rate

def speak(text):
    engine.say(text)
    engine.runAndWait()

def listen():
    r = sr.Recognizer()
    with sr.Microphone() as source:
        print("Listening...")
        audio = r.listen(source)
    try:
        text = r.recognize_google(audio)
        print(f"You said: {text}")
        return text.lower()
    except sr.UnknownValueError:
        print("Sorry, I didn't catch that.")
        return None
    except sr.RequestError:
        print("Could not request results.")
        return None

def parse_time(reminder_time_str):
    try:
        # Parse time like "15:30" or "3:30 pm"
        reminder_time = datetime.datetime.strptime(reminder_time_str, "%H:%M").time()
        return reminder_time
    except ValueError:
        try:
            reminder_time = datetime.datetime.strptime(reminder_time_str, "%I:%M %p").time()
            return reminder_time
        except ValueError:
            return None

def main():
    speak("Please say the reminder time in 24-hour format, for example, 15:30.")
    reminder_time_str = None
    while not reminder_time_str:
        reminder_time_str = listen()
        if reminder_time_str:
            # Clean input: keep only digits, colon, am/pm if present
            reminder_time_str = reminder_time_str.replace(" ", "")
            reminder_time = parse_time(reminder_time_str)
            if not reminder_time:
                speak("Time format not recognized. Please say the time again.")
                reminder_time_str = None

    speak("Please say your reminder message.")
    reminder_message = None
    while not reminder_message:
        reminder_message = listen()
        if not reminder_message:
            speak("I didn't catch that, please repeat your reminder message.")

    speak(f"Reminder set for {reminder_time_str}. I will remind you to: {reminder_message}")

    while True:
        now = datetime.datetime.now()
        if now.time().hour == reminder_time.hour and now.time().minute == reminder_time.minute:
            speak(f"Reminder: {reminder_message}")
            break
        time.sleep(15)

if __name__ == "__main__":
    main()

Requirements:

bash
CopyEdit
pip install SpeechRecognition pyttsx3 pyaudio

• On some systems, pyaudio is tricky to install. If on Windows, download the appropriate wheel from here.

• Run the script in a quiet room with a good microphone.

Would you like me to help with a version that uses text input instead?
