Amazon Alexa and Echo — The Voice Assistant You Talk to From Across the Room

Alexa is Amazon's cloud-based voice assistant, and it first appeared as the "brain" of Echo, a speaker you control by voice. Amazon unveiled Echo in the US on 6 November 2014, by invitation only. It cost $199, or $99 for Prime members for a limited time (GeekWire). Anyone could order one from 2015, with shipping from 14 July. Japanese-language Alexa arrived on 8 November 2017, three years after the US.

The first Echo: a cylinder you call "Alexa"

According to GeekWire's launch-day report, the first Echo was a cylinder 9.25 inches tall and 3.27 inches wide with seven microphones and noise cancellation, so it could hear a question even while playing music. It read the news and weather, played music, told the time, kept shopping lists, set alarms and answered stray questions, all after the user said "Alexa." Music came from Amazon's music library, Prime Music, TuneIn and iHeartRadio, and Bluetooth let it play audio from a phone.

Amazon's release of 23 June 2015 explains how it worked. The device itself listened only for the wake word; when it heard it, it lit up and streamed the audio to the cloud. Recognition and responses ran on Amazon Web Services, where a deep-neural-network speech recogniser trained on large amounts of far-field speech picked out an utterance spoken from across the room. Beam-forming combined the signals of the seven microphones to suppress noise, reverberation and competing speech. Because the brain lived in the cloud, Amazon said, the device gained features without being replaced.

The same release lists what had been added in the seven months since launch: Pandora and Audible, home control through Belkin WeMo and Philips Hue, sports scores, traffic, Google Calendar, IFTTT and re-ordering of Prime-eligible products. With that release Echo left its invitation phase and went on general sale at $179.99.

Skills: developers add jobs to Alexa

On 25 June 2015 Amazon announced the Alexa Skills Kit (ASK), a free set of self-service APIs and tools for adding new voice capabilities, called skills, to Alexa. Amazon said no experience in speech recognition or natural-language understanding was needed, because Amazon did the work of hearing and understanding the spoken request; an existing web service could be connected with a few lines of code.

That design turned Alexa from a single Amazon product into a place where other companies could put their own functions. When Alexa launched in Japan, more than 250 skills from partners including Ezaki Glico, Japan Airlines, Nissan and the Yomiuri Shimbun were built on the same kit.

Japan: November 2017, again by invitation

On 8 November 2017 Amazon.co.jp announced Japanese-language Alexa and three devices for the domestic market. As in the US, sales began by invitation.

Shipping was planned for the week of 13 November. Amazon said it had built Japanese speech and recognition technology, local knowledge and skills from Japanese companies from the ground up. The Alexa Skills Kit became available to Japanese developers the same day.

Privacy: the FTC settlement over children's recordings

A machine that sits in the room and waits to be called raised questions about recordings from the start. The most concrete resolution came on 31 May 2023, when the US Federal Trade Commission made an announcement.

According to the FTC, the complaint, filed by the Department of Justice on the FTC's behalf, charged that Amazon violated the Children's Online Privacy Protection Act (COPPA) Rule and deceived Alexa users and parents about its deletion practices. The FTC alleged that Amazon kept children's voice recordings indefinitely unless a parent asked for them to be deleted, and that even then it failed to delete the transcripts from all its databases. It also said the retained data helped improve the Alexa algorithm.

The proposed order announced with it required Amazon to pay a $25 million civil penalty, delete inactive child accounts and certain voice recordings and geolocation data, and stop using data subject to deletion requests to train its algorithms. The order needed federal court approval to take effect. The same day the FTC announced a separate action against Ring, an Amazon subsidiary.

It sold, but did it pay?

Echo spread as "a new category of device," but whether it worked as a business is another question. In July 2024 the Wall Street Journal, citing internal documents and people familiar with the matter, reported that Amazon's devices business lost more than $25 billion between 2017 and 2021 (as relayed by Quartz and Thurrott). That business covers Kindle, Fire TV Stick and video doorbells as well as Echo, and the WSJ said it could not obtain data for the years before and after. Echo speakers, the report said, were used more for alarms and other free functions than for shopping. An Amazon spokesperson replied that the company focuses on the value created when customers use its services, not only when they buy its devices. The loss figure comes from the reporting, not from Amazon.

Alexa+: rebuilt on large language models

On 26 February 2025 Amazon announced Alexa+. Amazon says it is built on large language models available on Amazon Bedrock, from Amazon Nova and Anthropic. To act on outside services and devices, it groups systems, APIs and instructions by type of task into what Amazon calls "experts", and Amazon promoted agentic features that let it navigate the web on its own, for instance to book a repair. In the US it costs $19.99 a month, with no extra charge for Prime members.

Amazon says tens of millions of people joined the Early Access programme, and in February 2026 it opened Alexa+ to everyone in the US and made it free for Prime members. Non-Prime users get a free, usage-limited chat version on Alexa.com and in the app. As of the July 2026 update Amazon lists Alexa+ as fully available in the US and Canada and in early access in Brazil, the UK, Mexico, Italy, Spain, Germany, Austria and France. In the same article Amazon says there are more than 600 million Alexa devices (Amazon's claim).

In Japan, Amazon Japan gave no launch timing at a 19 February 2026 event. According to ITmedia NEWS, the manager in charge said the timing could not be disclosed but that Japan was being discussed as the next priority after the US and Canada.

Where it fits

What was new about Alexa was not the voice assistant itself but where it lived. Siri on the iPhone 4S in 2011 lived in a phone in your hand; Echo sat in the room and assumed it would be called from a distance, pairing a microphone array with recognition in the cloud. That also brought into the home the question of where recordings are kept and who uses them. Alexa+, rebuilt on generative AI, is trying to stretch the same devices from answering to acting on the user's behalf.
