How to Generate Voice (Text-to-Speech) using JavaScript

In this article, you'll learn how to generate text-to-speech in minutes using JavaScript.

By leveraging powerful APIs, you can easily convert written text into natural-sounding speech, allowing you to enhance your applications with audio features.

This guide provides simple steps for integrating text-to-speech functionality into your JavaScript projects, helping developers create more accessible and interactive user experiences.

What is Voice Generation (Text-to-Speech)?

Text-to-Speech (TTS) technology converts written text into spoken words, enabling applications to "speak" text aloud.

This is achieved through AI models that process and synthesize speech in a natural, human-like tone. TTS can be integrated into various platforms to provide users with voice-enabled experiences.

Implementing Voice Generation in JavaScript

‍

Install JavaScript Requests Module

To interact with the Eden AI API, we will use axios, a popular JavaScript library for making HTTP requests. Install it by running the following command in your project directory:

    
npm install axios
    
  

‍

Code Example

Here’s an example of how to use the Eden AI API to perform a face comparison in JavaScript.

    
const axios = require("axios").default;

const options = {
  method: "POST",
  url: "https://api.edenai.run/v2/vision/face_comparison",
  headers: {
    authorization: "Bearer YOUR_API_KEY",
  },
  data: {
    image1: "BASE64_ENCODED_IMAGE1",
    image2: "BASE64_ENCODED_IMAGE2",
  },
};

axios
  .request(options)
  .then((response) => {
    console.log(response.data);
  })
  .catch((error) => {
    console.error(error);
  });
    
  

‍

• axios: We use axios to send HTTP requests to the Eden AI API.
  
• ‍Authorization: Replace YOUR_API_KEY with your actual API key obtained from Eden AI.‍
• image1 and image2: These are the two images you want to compare. You need to base64-encode the images before sending them in the request.‍
• URL: The endpoint https://api.edenai.run/v2/vision/face_comparison is used for face comparison.

Code Explanation:

• Request: The POST method is used to send the images for comparison. The data object contains the base64-encoded images you want to compare.
  
• Authorization: The API key in the Authorization header authenticates the request.
  
• Response: The API returns a response that includes whether the faces match or not, along with a confidence score.

‍

Interpreting the Results

Here’s an example of the response you might get after comparing the two images:

    
{
  "status": "success",
  "match": true,
  "confidence": 0.98
}
    
  

‍

• status: Indicates whether the request was successful.
  
• match: true means the faces match, while false indicates they don’t.‍
• confidence: A numeric score (between 0 and 1) indicating how confident the system is that the faces are the same.
