Amazon Alexa
Amazon Alexa,
known simply as
Alexa, is a
virtual
assistant developed by
Amazon,
first used in the
Amazon Echo and the Amazon Echo Dot
smart
speakers developed by
Amazon Lab126. It is capable of voice interaction,
music playback, making to-do lists, setting alarms, streaming podcasts, playing
audiobooks, and providing weather, traffic, sports, and other real-time
information, such as news. Alexa
can also control several
smart devices using itself as a
home
automation system. Users are able to extend the Alexa capabilities by
installing "skills" (additional functionality developed by
third-party vendors, in other settings more commonly called
apps
such as weather programs and audio features).
Most devices with Alexa allow users to activate the device using a wake-word
(such as
Alexa); other devices (such as the Amazon
mobile app
on
iOS or
Android) require the user to push a
button to activate Alexa's listening mode. Currently, interaction and
communication with Alexa are only available in English, German, French,
Italian, Spanish, and
Japanese. In November 2017, Alexa became available in the Canadian market in
English only.
As of September 2017, Amazon had more than 5,000 employees working on
Alexa and related products.
History
In November 2014, Amazon announced Alexa alongside the
Echo.
Alexa was inspired by the
computer
voice and
conversational system on board the
Starship Enterprise in science fiction
TV series and movies, beginning with
Star Trek: The Original Series
and
Star Trek: The Next Generation.
The name Alexa was chosen due to the fact that it has a hard consonant with
the X and therefore could be recognized with higher precision. The name is also
claimed to be reminiscent of the
Library of Alexandria, which is also used by
Amazon
Alexa Internet for the same reason.In June 2015,
Amazon announced Alexa Fund, a program that would invest in companies making
voice control skills and technologies. The US$100 million in funds has invested
in companies including
Ecobee, Orange Chef, Scout Alarm,
Garageio,
Toymail, MARA, and Mojio. In
2016, the
Alexa Prize was announced to advance the technology.
In January 2017, the first Alexa Conference took place in Nashville,
Tennessee, an independent gathering of the worldwide community of Alexa
developers and enthusiasts. The follow-up has been announced, to be keynoted by
original Amazon Alexa / Connected Home product head Ahmed Bouzid.
At the Amazon Web Services Re:Invent conference in Las Vegas, Amazon
announced Alexa for Business and the ability for app developers to have paid
add-ons to their skills.
In May 2018, Amazon announced that Alexa will be included into all of the
35,000 new
Lennar Corporation homes built this year.
App
A companion
app is
available from the
Apple App Store,
Google
Play, and
Amazon Appstore. The app can be used by owners of
Alexa-enabled devices to install skills, control music, manage alarms, and view
shopping lists. It also allows users to review the recognized text on the app
screen and to send feedback to Amazon concerning whether the recognition was
good or bad. A web interface is also available to set up compatible devices
(e.g., Amazon Echo, Amazon Dot, Amazon Echo Show)
Functions
Alexa
offers weather reports provided by
AccuWeather
and news provided by
TuneIn from a variety of sources including local radio
stations,
NPR, and
ESPN. Additionally,
Alexa-supported devices stream music from the owner's
Amazon
Music accounts and have built-in support for
Pandora
and
Spotify
accounts. Alexa
can play music from streaming services such as
Apple
Music and
Google Play Music from a phone or tablet. Alexa
can manage voice-controlled alarms, timers, and shopping and to-do lists, and
can access
Wikipedia
articles. Alexa devices will respond to questions about items in the user's
Google
Calendar. Alexa's
question answering ability is partly powered by
the
Wolfram Language. When questions are asked, Alexa
converts
sound
waves into text which allows it to gather information from various sources.
Behind the scenes, the data gathered is then parsed by
Wolfram's
technology to generate suitable and accurate answers. As of
November 2016, the Alexa Appstore had over 5,000 functions
("skills") available for users to download, up
from 1,000 functions in June 2016. As of
a partnership with fellow technology company,
Microsoft's
AI
Cortana became
available to use on Alexa enabled devices as of August 2018,
Amazon rolled out a new "Brief Mode," wherein Alexa would begin
responding with a beep sound rather than saying, "Okay," to confirm
receipt of a command.
Home automation
In the home automation space, Alexa can interact
with devices from several manufacturers including
Belkin,
ecobee, Geeni,
IFTTT,
Insteon,
LIFX,
LightwaveRF,
Nest ,
Philips Hue,
SmartThings,
Wink,
and Yonomi. The
Home Automation feature was launched on April 8, 2015.
Developers are able to create their own smart home skills using the
Alexa
Skills Kit.
In September 2018, Amazon announces a
microwave
oven that can be paired and controlled Echo device. It is sold under the
AmazonBasics
branding.
