🔧 What is gTTS?

gTTS stands for Google Text-to-Speech. It is a Python library and CLI tool to extract the spoken text from Google Translate. It's super simple and effective for making basic TTS (Text-to-Speech) programs.

---

✅ How It Works

• You type a text.
• The text is sent to Google's TTS API.
• It returns an MP3 audio file.
• You can play the file using any media player.

💡 Installation

First, install the library using pip:

pip install gTTS

👶 Basic Example Code

from gtts import gTTS
import os

text = "Hello! This is your computer speaking."
language = "en"

speech = gTTS(text=text, lang=language, slow=False)
speech.save("output.mp3")

# Play the file (Windows)
os.system("start output.mp3")

# For Linux or Mac
# os.system("mpg321 output.mp3")
