How to Pause, Resume, and Stop pyttsx3 from Speaking in Python

Have you ever wished to have more control over your text-to-speech application? If so, you might have run into the challenge of implementing functionality to pause, resume, and stop the speech being output by the pyttsx3 library in your Python projects. This can be particularly frustrating when building graphical user interfaces (GUIs) with Tkinter, where user interaction is essential.

In this guide, we'll explore how to implement the desired functionality effectively. We'll break down the solution in clear sections, so you can easily follow along and adapt it to your needs.

Understanding the Limitations of pyttsx3

Before we dive into the solution, it's important to note that the pyttsx3 library does not come with built-in methods to pause and resume speech. Instead, we have to simulate these features by breaking the text into manageable parts (words) and controlling the flow of speech through threading.

Solution Approach: Using Threading to Control Speech

Step 1: Setting Up Your Environment

To begin, ensure you have pyttsx3 installed, along with Tkinter, which usually comes pre-installed with Python.

You can install pyttsx3 using pip:

Step 2: Write the Code

Let's look at the complete code implementation:

Step 3: Key Elements of the Code

Threading: The Speaking class inherits from threading.Thread. This allows us to handle speech in a separate thread while still being responsive to button clicks.

Speech Control:

Pause: Pausing is controlled by adding a paused flag. If paused is True, the speech pauses until the resume method sets it back to False.

Stop: To stop speaking, we simply set the running flag to False.

Read Aloud: We start a new thread for reading if none exists. This ensures that multiple reads don't conflict.

Updating for Enhanced Features

If you prefer using a sound library like pygame for better control over audio playback, you can easily modify the implementation:

Conclusion

While pyttsx3 does not natively support pause and resume functionality, we can achieve effective control over speech output using threading along with a bit of clever coding. This approach not only enhances user experience but also allows for greater interaction with your Python applications.

Feel free to experiment and expand on this foundation to create a more robust text-to-speech solution tailored to your needs!
