Nowadays voice communication has become the easiest way to interact than the other mediums of communications. Since 1994, when Jeff Bezos founded Amazon, they have been the inventors from STEM to Prime to Web Services to Kindle and the latest addition of Echo, Echo Dot and Echo Show. Echo series connects to the voice-controlled intelligent personal assistant service Alexa, one among that best till date.  Alexa is named after the ancient library of Alexandria. Using Alexa you can call out your wishes and see them fulfilled—at least simple ones. For example to know the weather of any place, play music, do a Google search etc..

Alexa Enabled Devices available in the market are Amazon Echo, Echo Dot, Echo Show and a new addition announced The Echo Look. You can explore these amazing products in https://echosim.io and login to Amazon.

The Alexa Voice Service is currently only available for US, German and UK customers with an Amazon account.

The architecture of Alexa is, when the user asks something like “Alexa, tell me the weather of San Francisco”, the audio request will go to the Amazon voice Service(AVS) i.e Alexa .It converts speech to text. The keywords are “Weather” and “San Francisco”, processes it and returns as Voice to User. Alexa Skills have two parts Configuration i.e. data in Developer Portal and Hosted Service are responding to User requests The Hosted Services available are Amazon Lambda or an internet accessible HTTPS endpoint with a trusted certificate. You can build skills using Alexa Skills Kit(ASK). The Skills that are supporting here are Custom Skills, Flash Briefing Skill and Smart Home Skill.

About the architecture of Alexa Skills Kit(ASK), when the user speaks a phrase beginning with “Alexa” and the Echo hears it, the audio is sent to AVS for processing. An Alexa skill request is sent to your server(Lambda) for business logic processing. Then server responds with a JSON payload including text to speak. Finally, AVS sends your text back to the device for voice output.

The specialties of these device are the far field’s microphone and there’s no need of an activation, simply say the trigger words like “Alexa”(default),”Echo”, “Computer”. So that it can respond to Voice Commands from almost anywhere within Earshot. Microsoft’s Cortana , Google Assistant and Apple’s Siri provides the similar Services. However, if you get used to Alexa it feels much more natural and responsive than speaking to a phone-based voice assistant. Voice control frees you from being constantly tethered to your smartphone.

Manufacturers of automobiles, kitchen appliances, door locks, sprinklers, garage-door openers and many other recently connected products are working to bring to Alexa or a similar voice-driven service to their devices

Alexa is particularly useful for smart-home because it allows you to control your connected devices without having to take out your phone and launch an App.

Despite the success and growing interest in Alexa products and services, Amazon still faces scrutiny over the potential privacy implications of having an always-on, always-listening device in peoples’ homes, cars and other personal spaces.

I was excited to know about Echo, so tried my part to add Custom Skill in Alexa. I could build a sample Quiz where Alexa acts as a Quiz Master. It was fun, but more importantly, I am onto see how effectively this can be benefited for Connected Homes.

Ultimately, Alexa is using natural language processing system(voice)to interact, so no need for the user to change his accent. Be You and Enjoy Alexa!

IoT in Construction Industry

I absolutely love my job and what we do at SequoiaAT. I am fortunate to learn about many new industries and technologies as we work on helping Startups and Fortune 500 companies with new product ideas. As part of engaging with a recent customer, I got a learn a lot about the home construction business in the USA.

I was surprised to see how one of the oldest industries know to mankind- the home building was slow in adopting the latest technology trends. Although the commercial construction side has been fast to adapt to the new technologies to provide energy efficient building, the home construction side has been way behind on this

I think the reason for slow adoption is Homes are basic necessities of humans and probably the biggest investment an average person makes in his/her life. So given everything equal, people, in general, will spend more money on buying a bigger house for same dollar value than buying a high-tech house. Also, another reason could be that the necessity always exists. There is no urgency to reinvent or adopt technology at a fast pace.

As Smart buildings become popular and the norm, the home construction industry will have to change itself and adapt itself to the new norms. Sooner or later there will be a disruptive force in the industry. The scope of bringing IoT-enabled technologies are unlimited in every part of the supply chain right from selling to occupancy. As an example – Having an IoT beacon beam out to potential buyer passing by information about the house or lot.

Incorporating some of the smart sensors for occupancy, temperature etc. during constructions itself rather than retrofitting. It will save 100’s and 1000’s of dollars for the homeowners in long run for a fraction of the additional cost while setting it up. Devices like Powerwalls from Tesla or leak Detection systems from Flowlabs will get embedded into the home construction process. Smart asset tracking and people tracking will ensure that right tools are present at the right place at right time.

The backend construction cycle itself will get faster with the use of technology as the tools & equipment be used can be tracked better and maintained better leading to less downtime and loss of working hours. IoT enables devices will also ensure better safety at the worksite and can lead to better co-ordination.

Even for a consumer point of view, warranties can be tracked better as every single component used in the house being build can be tracked and managed to their warranty.  I think like commercial building owners advertise how energy efficient the building are, builders need to start paying more attention to  HERS index (Home Energy Efficiency Rating System)

As of now, I think many of these technology implementations are at a hobbyist level and need mass adoption. I think buyers need to start pushing on the HERS index rating to put pressure on homebuilders to use better technology to produce more energy efficient homes.

Home construction companies which adopt and embrace the new technologies will have better and faster turn around time and edged out the competition. Plumbers, electricians, painters etc. will have to learn new skills to incorporate technology tools into their work to stay competitive.
