The rise of voice interfaces and conversational UI has been one of the most exciting trends in web development over the past few years. With the increasing popularity of smart speakers and voice assistants, people are becoming more comfortable with using their voice to interact with technology. In this post, we’ll explore why voice interfaces are becoming so popular, what conversational UI is, and how you can start building your own voice-based applications.

Why are voice interfaces becoming so popular?

There are a number of reasons why voice interfaces are becoming more popular. First, they offer a convenient and natural way to interact with technology. People are used to speaking to each other, so using their voice to interact with technology feels more intuitive than typing on a keyboard or clicking a mouse. Additionally, voice interfaces can be used in a wide variety of settings, including when people are driving, cooking, or otherwise occupied with their hands. Finally, voice interfaces are becoming more accurate and reliable thanks to advances in natural language processing (NLP) and machine learning.

What is conversational UI?

Conversational UI is a way of designing user interfaces that feels like having a conversation with a human. Instead of clicking on buttons or filling out forms, users interact with the application by speaking to it. The application responds with spoken or written text, just like a human would. Conversational UI can be used for a wide variety of applications, including chatbots, voice assistants, and even customer service applications.

How can you start building your own voice-based applications?

If you’re interested in building your own voice-based applications, there are a few things you’ll need to keep in mind. First, you’ll need to choose a platform for your application. There are a number of platforms available, including Amazon Alexa, Google Assistant, and Microsoft Cortana. Each platform has its own set of tools and APIs, so you’ll need to choose the one that best fits your needs.

Once you’ve chosen a platform, you’ll need to design your application’s conversation flow. This involves mapping out the various ways users might interact with your application, and designing responses for each interaction. You’ll also need to consider how your application will handle errors or misunderstandings.

Next, you’ll need to develop your application using the platform’s tools and APIs. This may involve writing code in a programming language like Python or JavaScript, or using a visual interface like Amazon’s Alexa Skills Kit. You’ll also need to test your application to make sure it works as expected.

Finally, you’ll need to publish your application to the platform’s app store or marketplace. This will make it available to users, who can then download and use it on their own devices.


The rise of voice interfaces and conversational UI is an exciting development in web development. By building voice-based applications, you can create a more natural and intuitive way for users to interact with your technology. With the right tools and techniques, you can start building your own voice-based applications today.
