Alexa is an intelligent personal assistant developed by Amazon Lab126, made popular by the Amazon Echo and the Amazon Echo Dot. It is capable of voice interaction, music playback, making to-do lists, setting alarms, streaming podcasts, playing audiobooks, and providing weather, traffic, and other real time information, such as news. Alexa can also control several smart devices using itself as a home automation system.[2] Most devices with Alexa allow users to activate the device using a wake-word (such as Echo); other devices (such as the Amazon app on iOS or Android) require the user to push a button to activate Alexa's listening mode. Currently, interaction and communication with Alexa is only available in English and German.

HistoryEdit

In November 2014, Amazon announced Alexa alongside Echo.[3] 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 TOS and Star Trek TNG. 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.[4][5] In June 2015, Amazon announced Alexa Fund, a program that would invest in companies making voice control skills and technologies. The US$100M in funds has invested in companies including Ecobee, Orange Chef, Scout Alarm, Garageio, Toymail, MARA, and Mojio.[6] In 2016 the Alexa Prize was announced to advance the technology.

AppEdit

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).

FunctionsEdit

Alexa offers weather reports provided by AccuWeather and news provided by TuneIn from a variety of sources including local radio stations, NPR, and ESPN.[7] Additionally, Alexa-supported devices stream music from the owner's Amazon Music accounts and have built-in support for Pandora and Spotify accounts.[8] 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. As of November 2016, the Alexa Appstore had over 5,000 functions ("skills") available for users to download,[9] up from 1,000 functions in June 2016.[10]

MusicEdit

Home automationEdit

In the home automation space, Alexa can interact with devices from Yonomi,[11] Philips Hue, Belkin Wemo, SmartThings, Wink,[12][13] Insteon, LIFX, IFTTT, ecobee, and Nest Thermostats.[14] The Home Automation feature was launched on April 8th, 2015.[15]

OrderingEdit

Take-out food can be ordered using Alexa; as of January 2017 food ordering using Alexa is supported by Wingstop, Domino's Pizza and Pizza Hut.[16] Also, users of Alexa in the UK can order meals via Just Eat.[17]

FactsEdit

Alexa Skills KitEdit

Amazon allows developers to build and publish skills for Alexa using the Alexa Skills Kit. These skills are 3rd-party developed voice experiences that add to the capabilities of any Alexa-enabled device (such as the Echo). These skills are available for free download using the Alexa app. Examples of skills include the ability to play music, answer general questions, set an alarm, order a pizza, get an Uber, and more. Skills are continuously being added to increase the capabilities available to the user. The Alexa Skills Kit is a collection of self-service APIs, tools, documentation and code samples that make it fast and easy for any developer to add skills to Alexa. Developers can also use the "Smart Home Skill API",[18] a new addition to the Alexa Skills Kit, to easily teach Alexa how to control cloud-controlled lighting and thermostat devices. All of the code runs in the cloud – nothing is on any user device. A developer can follow tutorials to learn how to quickly build voice experiences for their new and existing applications.[19]

Alexa Voice ServiceEdit

Amazon allows device manufacturers to integrate Alexa voice capabilities into their own connected products by using the Alexa Voice Service (AVS), a cloud-based service that provides APIs to interface with Alexa. Products built using AVS have access to Alexa's growing list of capabilities including all of the Alexa Skills. AVS provides cloud-based automatic speech recognition (ASR) and natural language understanding (NLU). There are no fees for companies looking to integrate Alexa into their products by using AVS.

Amazon LexEdit

On November 30, 2016 Amazon announced that they will make the speech recognition and natural language processing technology behind Alexa available for developers under the name of Amazon Lex. This new service would allow developers to create their own chatbots that can interact in a conversational manner, similar to Alexa. Along with the connection to various Amazon services, the initial version will provide connectivity to Facebook Messenger, with Slack and Twilio integration to follow.[20][21]

ReceptionEdit

There are concerns about the access Amazon has to private conversations in the home and other non-verbal indications that can identify who is present in the home with non-stop audio pick-up from Alexa-enabled devices.[22][23] Amazon responds to these concerns by stating that the devices only stream recordings from the user's home when the 'wake word' activates the device. The device is technically capable of streaming voice recordings at all times, and in fact will always be listening to detect if a user has uttered the wake word.

Amazon uses past voice recordings sent to the cloud service to improve response to future questions the user may pose. To address privacy concerns, the user can delete voice recordings that are currently associated with the user's account, but doing so may degrade the user's experience using search functions. To delete these recordings, the user can visit the Manage My Device page on Amazon.com or contact Amazon customer service.

Alexa uses an address stored in the companion app when it needs a location.[24] Amazon and third-party apps and websites use location information to provide location-based services and store information to provide voice services, the Maps app, Find Your Device, and to monitor the performance and accuracy of location services. For example, Echo voice services use the user's location to respond to the user's requests for nearby restaurants or stores. Similarly, Alexa uses the user's location to process the user's mapping-related requests and improve the Maps experience. All information collected is subject to the Amazon.com Privacy Notice.[25]

Amazon retains digital recordings of users' audio spoken after the "wake up word," and while the audio recordings are subject to demands by law enforcement, government agents, and other entities via subpoena, Amazon publishes some information about the warrants it receives, the subpoenas it receives, and some of the warrant-less demands it receives, allowing customers some indication as to the percentage of illegal demands for customer information it receives.[26]

Supported DevicesEdit

Alexa PrizeEdit

In September 2016, a university student competition called the Alexa Prize was announced for November of that year.[53] The goal of the award is to advance conversational AI through voice. The prize is equipped with a total of $2.5 million and teams and their universities can win cash and research grants. The process starts with a team selection in 2016, final award will be announced in 2017.[54] The 2017 inaugural competition focuses on the challenge of building a socialbot that can converse coherently and engagingly with humans on popular topics for 20 minutes. This is similar to the Loebner Prize, but with higher prize money.

Alexa FundEdit

Given Amazon's strong belief in voice technologies, Amazon announced a US$100 million venture capital fund on June 25, 2015. By specifically targeting developers, device-makers and innovative companies of all sizes, Amazon aims at making digital voice assistants more powerful for its users.[55] Eligible projects for financial funding base on either creating new Alexa capabilities by using the Alexa Skills Kit (ASK) or Alexa Voice Service (AVS)[56].

Amazon states three specific focus areas that are of interest for Alexa Fund support, irrespective of whether the technology is developed by early-stage pre-revenue companies or mature and established players. These three areas are:

  • Hardware products for inside the home, outside the home, or on-the-go (Alexa Voice Service, AVS)
  • Skills that deliver new abilities to Alexa-enabled devices (Alexa Skills Kit, ASK)
  • New contributions to the science behind voice technology, e.g. text to speech, speech to text, automatic speech recognition, artificial intelligence

The final selection of companies originates from the customer perspective and works backwards, specific elements that are considered for potential investments are: level of customer-centricity, degree of innovation, motivation of leadership, fit to Alexa product/service line, amount of other funding raised. [57]

Besides financial support, Amazon provides business and technology expertise, help for bringing products to the market, aid for hard- and software development as well as enhanced marketing support on proprietary Amazon platforms.

The list of funded business includes (in alphabetical order): DefinedCrows, Dragon Innovation, ecobee, Embodied Inc., Garageio, invoxia, kitt.ai, Luma, Mara, Mojio (2x times), Musaic, Nucleus, Orange Chef, Owlet Baby Care, Petnet, Rachio, Ring, Scout, Sutro, Thalmic Labs, Toymail Co., TrackR and Vesper. [58]

Alexa ConferenceEdit

In January 2017, the first-ever Alexa Conference took place in Nashville, Tennessee, an independent gathering of the worldwide community of Alexa developers and enthusiasts.[59][60][61] The follow-up has been announced, to be keynoted by original Amazon Alexa / Connected Home product head Ahmed Bouzid.[62]

The Alexa Alumni SocietyEdit

In March 2016, The Alexa Alumni Society was launched by former Amazon Alexa employees to keep the original founders of Alexa connected with each other and with the members of the growing Alexa team. The society has a Facebook page where Alumni and current members post messages and pictures.[63]
