How to add text-to-speech feature in flutter app?

Hello @mdsarfaraj

I hope this message finds you well!

In Flutter, you can incorporate text-to-speech (TTS) functionality into your app using the 'flutter_tts' package. This package provides a simple and convenient way to convert text into speech.

Thank you.

Hello MD, 

I was thrilled to hear about your idea to build an application that can be used by visually impaired individuals through text-to-speech functionality. Congratulations on such a noble cause! Your initiative will undoubtedly make a significant impact on the lives of visually impaired individuals. It's inspiring to see how technology can be used to improve accessibility and inclusivity for all. I'm excited to see the positive impact your application.

Few things that I would suggest: 

Firstly, Visually impaired individuals may have difficulty navigating complex interfaces. Make sure to keep the interface simple and easy to navigate using keyboard shortcuts or other input methods.

Secondly, If possible use text-to-speech functionality to provide audio feedback to the user. This will help the user understand the interface and the actions they are performing.

Thirdly, For users with low vision, high contrast colors can help make the interface easier to see. Use colors that have a high contrast between the foreground and background.

Finally, Provide keyboard shortcuts for all interface functions so that users can navigate the application without using a mouse.

Bonus, Some users may have difficulty typing. Providing an option for speech input can make it easier for these users to use the application.

Hello Tuhin,

Thank you for your response. I need to build an application that can be used by visually impaired individuals, where they can access the application through text-to-speech functionality.

Flutter has a plugin called flutter_tts that can be used to add text-to-speech functionality in your app. Here are the steps to integrate it into your Flutter app: Add the flutter_tts dependency to your pubspec.yaml file:

dependencies:
  flutter_tts: ^3.0.0

  Import the flutter_tts package in your Dart code:

import 'package:flutter_tts/flutter_tts.dart';

Create an instance of the FlutterTts class:

FlutterTts flutterTts = FlutterTts();

Use the speak method to convert text to speech:

await flutterTts.speak('Hello, world!');

You can also pass additional parameters to customize the speech output, such as the language, pitch, and volume:

await flutterTts.setLanguage('en-US');
await flutterTts.setPitch(1.5);
await flutterTts.setVolume(0.5);

To stop the speech output, use the stop method:

await flutterTts.stop();

That's it!
