Learn How to Build Devices with AVS
Interaction Model

Envision how you want customers to interact with Alexa on your product – from across the room, hands-free, or with the press or tap of a button.

Hardware Requirements

You’ll need a microphone array for audio pickup, a processor to run the AVS client, internet connectivity to send audio to the cloud, and a speaker to play back audio for the customer.

Alexa Features

Consider how to design a product that takes advantage of the many cloud-based features and add-on capabilities that make Alexa products desirable for customers.

Cloud-Based Features

Alexa is always getting smarter with new features and capabilities added to the cloud. When you connect your device-side client to the Alexa Voice Service, you give customers access to a wealth of information. All they have to do is ask.


Alexa helps you stay connected to the news and offers answers to your questions fast. Just ask for your Flash Briefing, weather or sports updates, information on nearby businesses, or how many cups are in a liter.

Streaming Media

Enhance the Alexa experience on your product by offering customers access to streaming media from providers like Amazon Music, iHeartRadio, TuneIn, SiriusXM, Pandora, Spotify, and Audible.


Alexa makes life easier by helping you multitask. Set kitchen timers, wake-up alarms, manage reminders, add items to your shopping or to-do lists, and ask what’s on your calendar.

Smart Home

Alexa enables you to control compatible smart home devices, such as lights, thermostats, and locks. Now with ESP, Alexa identifies the best voice-forward device to respond to your request.

Cloud-Based Intelligence

AVS handles complex automatic speech recognition (ASR), natural language understanding (NLU), and text-to-speech (TTS) processes in the cloud, making it easier for you to build AI-powered products.

Alexa Skills/Fun & Games

Give customers access to thousands of custom skills, including Domino’s, Uber, Jeopardy, and Starbucks on any device with Alexa built-in.

We provide add-on capabilities, such as streaming media, graphical user interfaces, and proactive notifications to commercial device makers. These features require additional development work and testing to ensure the best user experience for end-customers.
