Alexa Skills Kit

Give Your Vision a Voice and Reach More Customers

Why Build Alexa Skills?

Alexa is Amazon’s cloud-based voice service and the brain behind tens of millions of devices including the Echo family of devices, FireTV, Fire Tablet, and third-party devices with Alexa built-in. You can build capabilities, or skills, that make Alexa smarter and make everyday tasks faster, easier, and more delightful for customers. Tens of thousands of developers have built skills using the Alexa Skills Kit (ASK), a collection of self-service APIs, tools, documentation, and code samples. With ASK, anyone can leverage Amazon’s knowledge in voice design to build quickly and easily. Start building today to reimagine your customer experience for voice and reach customers where they are.

What You Can Do

Deliver habit-forming skills that entertain, inform, and deliver value to the whole family and keep them coming back.

Add Visual and Touch Elements

Design, build, and deploy visually rich experiences to tens of millions of Alexa devices with screens. Use the Alexa Presentation Language to create voice-first, visual Alexa skills that adapt to different device types, including Echo Show, Echo Spot, Fire TV, Fire Tablet, and more.

Alexa Skills Kit Capabilities

An Alexa skill includes a voice user interface, or VUI, to understand customer intents, and a back-end cloud service to process intents and tell Alexa how to respond. You can use capabilities in the Alexa Skills Kit to deliver both.


Alexa converts spoken words to text using automatic speech recognition (ASR), deduces the speaker’s meaning using natural language understanding (NLU), and provides the underlying customer intent to your skill.
