Editor’s note: This is part one of our Makers Academy series for Ruby developers. Learn more about this free training on the Alexa Skills Kit in this blog post

Welcome to the first module of Makers Academy's short course on building Alexa skills using Ruby. Amazon's Alexa Skills Kit allows developers to extend existing applications with deep voice integration and construct entirely new applications that leverage the cutting-edge voice-controlled technology.

This course will cover all the terminology and techniques required to get fully-functional skills pushed live to owners of Alexa-enabled devices all around the world using Ruby and Sinatra.

What's in This Module?

This module contains a basic introduction to scaffolding a skill and interacting with Alexa. This module introduces:

  • Intent schemas
  • Utterances
  • Alexa communication paradigm
  • Tunneling a local application using ngrok over HTTPS
  • Connecting Alexa to a local development environment
  • Alexa-style JSON requests and responses 

During this module, you will construct a simple skill called “Hello World.” While building this skill, you will come to understand how the above concepts work and play together. This module uses:

  • Sinatra
  • Ruby's JSON library

Let's get started!

It’s here. Huawei released an over-the-air (OTA) update today bringing hands-free Amazon Alexa capabilities to Mate 9 smartphones in the US. New Mate 9 smartphones will ship with the Huawei Alexa application pre-installed, making it the first Android smartphone to have the cloud-based voice service as a native, out-of-the-box feature.

Huawei introduced its flagship Mate 9 device in the US at CES 2017. The Mate 9 was built smart, with a machine learning algorithm designed to improve device performance over time. Now, Mate 9 is even smarter thanks to the Alexa Voice Service (AVS).

We all hold interesting data in our heads. Maybe it's a list of all the action figures we played with as a kid, specific details about the 50 U.S. states, or a historical list of the starting quarterbacks for our favorite football team. When we're with friends, sometimes we'll even quiz each other on these nuanced categories of information. It's a fun, interactive way to share our knowledge and learn more about our favorite topics. 

You can now bring that experience to Alexa using our new quiz skill template. You provide the data and the number of properties in that data, and Alexa will dynamically build a quiz game for you.

The Alexa skills catalog is home to more than 10,000 skills thanks to our amazing developer community. As most you know, every Alexa skill submitted to Amazon undergoes a certification process prior to being published in our public catalog.

To help you navigate the certification process, let me share its main purpose and requirements, the top issues we're seeing, and some helpful reference material.

All certified skills meet our requirements for policy, security, functionality, and voice interface and user experience. These certification requirements help us maintain a high quality bar for our catalog. It also ensures that the third-party skills our customers consume on Alexa-enabled devices are safe and work well.

These certification requirements are specified in our technical documentation and certification checklist. We encourage you to save this link and reference it often as you develop your skills and prepare to submit them to Amazon. Doing this should...

We’re pleased to announce our collaboration with Makers Academy on a new Alexa Skills Kit training course for Ruby developers.

Makers Academy is a leading web developer bootcamp based in London, UK. Its highly-selective, full-time program teaches the principles of software craftsmanship. Makers Academy has graduated over 700 students into their dream jobs as junior developers.

We believe natural user interfaces such as those based on speech represent the next major disruption in computing. Now is a great time for developers to take advantage of this new form of interaction and to learn to build voice-first experiences for Alexa, the voice service that powers Amazon Echo. Makers Academy’s mission is to teach students the most used technologies in today's marketplace, and we’re excited to team up to prepare you for the future of voice computing.

Amazon today announced a new program that will make it free for tens of thousands of Alexa developers to build and host most Alexa skills using Amazon Web Services (AWS). Many Alexa skill developers currently take advantage of the AWS Free Tier, which offers one million AWS Lambda requests and up to 750 hours of Amazon Elastic Compute Cloud (Amazon EC2) compute time per month at no charge. However, if developers exceed the AWS Free Tier limits, they may incur AWS usage charges each month.

Now, developers with a live Alexa skill can apply to receive a $100 AWS promotional credit and can also receive an additional $100 per month in AWS promotional credits if they incur AWS usage charges for their skill – making it free for developers to build and host most Alexa skills. Our goal is to free up developers to create more robust and unique skills that can take advantage of AWS services. We can’t wait to see what you create.

The Ford Motor Company announced a two-phased approach to integrating Amazon Alexa into its 2017 line of vehicles at CES. The first phase makes it easy for electric Ford vehicle owners to connect to their cars from the comfort of their homes through the MyFord Mobile skill, which launched in late January 2017.

Customers with a Ford plug-in vehicle, such as the C-Max Energi, Fusion Energi, or Focus Electric, can enable the MyFord Mobile skill to issue a range of remote commands and obtain vehicle information.

Technology in the car keeps drivers informed and connected. Logitech, a global leader in personal computing and accessories, is using voice control and the Alexa Voice Service (AVS) to help drivers stay focused on the road.

The company built ZeroTouch, a product that enables drivers to use their voice to control mobile-based applications on their Android phones or access cloud-based services via Amazon Alexa.

ZeroTouch is a combination of hardware and software that creates a hands-free voice experience in any car. The magnetic hardware car mount holds a phone in place either on the car dash or an air vent. The ZeroTouch mobile application launches via BluetoothⓇ and its voice control feature is activated with the wave of a hand.

In 2016, tens of thousands of developers visited the Alexa GitHub to learn how to build their own Alexa-enabled prototype with the Alexa Voice Service (AVS) and a Raspberry Pi. The community built some amazing projects, from magic mirrors and voice-enabled coffee machines to talking fish and alarm clocks.

If you’re new to voice user interface (VUI) design or you just want to learn more about AVS, the webinar recording below covers key concepts and examples around hardware selection, AVS development tools for commercial developers, best practices for enabling hands-free voice interaction, and how to build a robust Alexa Voice Service client.

Today we are happy to announce lock control and query, a new feature in the Smart Home Skill API now available in the US, with support for the UK and Germany coming soon. This feature is supported with locks from August, Yale, Kwikset, and Schlage as well as hub support from SmartThings and Wink. Now any developer targeting devices with locking behavior can enable customers to issue a voice command such as, “Alexa, lock the front door.” In addition, developers can build in support for customers asking for the status of a smart locking device with a voice command such as, “Alexa, is the front door locked?” LockAPI_blog.png

Much like the recently announced thermostat query feature, the lock query feature simplifies development efforts by enabling specific voice interactive experiences straight from the Smart Home Skill API. This is accomplished under the new Alexa.ConnectedHome.Query namespace.

Developers can report errors using the same namespace. These errors are then used to guide the customer with the proper corrective actions. It’s crucial that developers return meaningful and correct errors so that customers can feel confident about the status of their locks. For example, if the smart locking device is unable to provide a stateful value because a door is open, developers should report this in their directive response as shown below.
