Why build skills?

Get in early

Natural user interfaces, such as those based on speech, represent the next major disruption in computing. Alexa provides you with an opportunity to take advantage of the new form of interaction.

Reach more customers

Engage with your customers through voice on Alexa-enabled devices, including Amazon Echo, Echo Dot, Amazon Tap, Fire TV devices and all devices powered by the Alexa Voice Service.

Create engaging experiences

Delight your audience with a completely new way to interact with your service. Customers don't need to use their hands or eyes, they only have to "ask" and it's at their command, often becoming a daily habit.

Gain expertise in voice design

The Alexa Skills Kit is a low-friction way to learn to build for voice. Create your first Alexa skill and add a valuable new "skill" to your developer toolkit. You can get a prototype up and running in just a few hours.

Scale in the cloud

If you have an existing cloud-based service, you can easily use that to start. If not, AWS Lambda makes it really easy to build a cloud-based service that responds quickly to a voice request.

Build for free

ASK is free to use. AWS Lambda is also free for the first one million calls per month, which can support skill hosting for most developers.

Create a smarter home with Alexa

Alexa, Amazon’s cloud-based voice service, powers voice experiences on millions of devices in the home, including Amazon Echo and Echo Dot, Amazon Tap, and Fire TV devices. The Alexa Voice Service (AVS) makes it possible to add voice experiences to any connected hardware that has a speaker and microphone. Now you can use the Smart Home Skill API within the Alexa Skills Kit to easily extend Alexa’s smart home capabilities. You can also create custom skills with ASK. Customers will be able control all their smart home devices simply by using their voice.

Build custom voice experiences with Alexa

How will customers use your skills?

Alexa is the wake word and starts the conversation. Your service gets called when customers use your invocation name, such as "Alexa, ask Greeter to say hello world." This example is a simple command-oriented one. ASK also supports sophisticated multi-command dialogues and parameter passing.

The above example would work like this:

"Alexa" is the wake word that starts the conversation.

"Ask...to" is one of the supported phrases for requesting a service.

"Greeter" is the invocation name that identifies the skill the customer wants.

"Say hello world" is the specific request, question, or command.
