Talkify - Integrate Multilingual Text-to-Speech with Talkify JavaScript Library

Talkify Project Overview

Talkify is an innovative JavaScript library designed to integrate text-to-speech (TTS) capabilities into websites quickly and efficiently. Originally developed for the Talkify.net platform, this library allows websites to speak to their visitors with high-quality voices available in numerous languages.

Key Features and Benefits

High-Quality Voices: Talkify provides users with access to a broad range of high-quality TTS voices. These voices support a variety of languages, including English, Chinese, Swedish, German, Korean, and many more.
Multiple Language Support: Talkify boasts an impressive list of supported languages, ensuring that users from different linguistic backgrounds can experience spoken content in their native tongue.
User-Friendly Installation: The installation process for Talkify is straightforward, with support for popular package managers like Bower and npm. Whether you choose $ bower install talkify or $ npm install talkify-tts, you can have Talkify up and running on your website in no time.
Text Highlighting: This feature enhances readability by highlighting text as it is being read, allowing users to follow along easily.
Customizable Voice Features: With Talkify, you can control the pitch, speech rate, volume, and even add pauses between words to make the spoken content more natural and engaging.
SSML Support: Enabling the use of Speech Synthesis Markup Language (SSML) allows users to refine and customize the speech output further to enhance the listening experience.
Flexible UI Options: Talkify integrates seamlessly with UI options, providing users with enhanced visibility and interaction such as enhanced text visibility options and audio controls.

Getting Started with Talkify

To start using Talkify, include the necessary scripts and stylesheets in your project. Opt for either the minified or non-minified versions, depending on your needs:

<script src="talkify.min.js"></script>

<script src="talkify.js"></script>

You can find stylesheets in the /styles directory, which should be included based on your UI requirements, such as the "modern" UI option.

Once set up, you can create a new TTS player and define how it interacts with your webpage content. For example, to play all text from top to bottom:

var player = new talkify.TtsPlayer().enableTextHighlighting();
var playlist = new talkify.playlist()
    .begin()
    .usingPlayer(player)
    .withTextInteraction()
    .withElements(document.querySelectorAll('p'))
    .build();    
playlist.play();

Advanced Configuration

Talkify offers comprehensive configuration settings, including:

Debug Mode: An option to turn on debug output for troubleshooting and development purposes.
API-Key Requirement: To use Talkify's hosted backend voices, an API key is necessary, obtainable from the Talkify portal, which provides 1000 free requests per month.
Cross-Platform Events: Subscribe to events across different parts of Talkify, enabling seamless interaction and response to playback actions, enhancing user experience.

Talkify can be integrated into a variety of applications, such as enhancing website accessibility, providing auditory feedback for form inputs, and enabling dynamic text playback for educational content presentations. It's especially beneficial for websites aiming to reach broader, more diverse audiences by adding multilingual support and voice interactivity.
