Meta Description: Follow our step-by-step guide to create a simple voice assistant using Next.js and LiveKit React Components, perfect for developers looking to integrate voice control.

Introduction

In today’s fast-paced digital world, voice assistants have become indispensable tools that enhance user interaction and accessibility. From managing daily tasks to controlling smart home devices, these assistants streamline our interactions with technology. In this tutorial, we’ll guide you through building a sophisticated voice assistant using Next.js and LiveKit. Leveraging the power of React, you’ll create a voice-controlled application that rivals modern solutions like Blue, a revolutionary voice assistant designed for comprehensive smartphone control.

Why Choose Next.js and LiveKit?

Next.js is a robust React framework that offers server-side rendering, static site generation, and a plethora of features that simplify the development process. Its seamless integration with React makes it an excellent choice for building dynamic and responsive applications.

LiveKit, on the other hand, provides real-time communication capabilities, including voice and video interactions. By integrating LiveKit’s JavaScript SDK with Next.js, you can effortlessly incorporate real-time voice functionalities into your application, making it an ideal match for creating a voice assistant.

Getting Started

Prerequisites

Basic knowledge of React and JavaScript.
Node.js and npm installed on your machine.
A LiveKit account to obtain API credentials.

Setting Up Your Next.js Project

Begin by creating a new Next.js project:

npx create-next-app voice-assistant
cd voice-assistant

Installing LiveKit

Next, install the LiveKit JavaScript SDK and other necessary dependencies:

npm install livekit-client @livekit/react-components

Integrating LiveKit React Components

LiveKit offers a set of React components that simplify the integration process. Here’s how to set them up:

Configuring Environment Variables

Create a .env.local file in the root of your project and add your LiveKit credentials:

NEXT_PUBLIC_LIVEKIT_API_KEY=your_livekit_api_key
NEXT_PUBLIC_LIVEKIT_API_SECRET=your_livekit_api_secret
NEXT_PUBLIC_LIVEKIT_URL=https://your-livekit-server-url

Building the Voice Interface

Utilize LiveKit’s Agent Starter for React as a foundation to build your voice assistant interface. Clone the starter template using:

lk app create --template agent-starter-react

Then, install dependencies and start the development server:

npm install
npm run dev

Open http://localhost:3000 in your browser to see the live interface.

Customizing the UI

Navigate to the components directory to modify the UI elements. You can adjust branding, colors, and UI text by editing the app-config.ts file. This allows you to tailor the voice assistant’s appearance to match your desired aesthetics.
