Google Nest (smart speakers)

Google Nest, previously named Google Home, is a line of smart speakers developed by Google under the Google Nest brand. The devices enable users to speak voice commands to interact with services through Google Assistant, the company's virtual assistant. Both in-house and third-party services are integrated, allowing users to listen to music, control playback of videos or photos, or receive news updates entirely by voice. Google Nest devices also have integrated support for home automation, letting users control smart home appliances with their voice command. The first device, Google Home, was released in the United States in November 2016; subsequent product releases have occurred globally since 2017.

Through software updates to Google Nest devices and Google Assistant, additional functionality has been added over time. For example, multiple speakers can be set up for synchronized playback of music. An update in April 2017 brought multi-user support, allowing the device to distinguish between up to six people by voice. In May 2017, Google announced multiple updates, including: hands-free phone calling at no cost in Canada and the United States; proactive reminders ahead of scheduled events; visual responses on mobile devices or Chromecast-enabled televisions; Bluetooth audio streaming; and the ability to add reminders and calendar appointments.


The original Google Home speaker released in November 2016 featured a cylindrical shape with colored status LEDs on top. In October 2017, Google announced two additions to the product lineup, the miniature puck-shaped Google Home Mini and a larger Google Home Max. In October 2018, the company released the Google Home Hub, a smart speaker with a 7-inch touchscreen. In May 2019, Google announced that Google Home devices would be rebranded under the Google Nest banner, and it unveiled the Nest Hub Max, a larger smart display.

History[edit]

In March 2016, reports were published about Google developing a wireless speaker to compete against the Amazon Echo.[3] Google Home was officially announced at the company's developer conference in May 2016,[4][5] where it was also announced that Home would run the Google Assistant (a conversational evolution of Google Now intended to be integrated in other products announced at the conference as well).[6]


In October 2016, the iOS and Android mobile app used to initially set up Google Home and Google's other streaming devices was renamed from "Google Cast" to "Google Home", leaving Google Cast as the name solely of the protocol that "sends" audio/video content to play back on another device.[7] The Google Home smart speaker was released in the US on November 4, 2016,[8][9][10] and in the UK on April 6, 2017.[11][12] In May 2017, Google announced that Home would be heading to Australia, Canada, France, Germany, and Japan in middle 2017,[13][14] and the device subsequently became available for pre-order in Canada on June 2, 2017, with a retail date of June 26.[15][16] In July 2017, Google announced the release of Google Home in Australia on July 20, 2017,[17] France on August 3, 2017,[18] Germany on August 8, 2017,[19] and Italy on March 27, 2018.[20]


On October 4, 2017, Google announced Google Home Mini, a smaller, less expensive variant that was released on October 19, 2017,[21] as well as Google Home Max, a larger, more expensive variant that was released on December 11, 2017.[22]


The Google Home and Home Mini were released in India on April 10, 2018,[23] and the Nest Hub was released on August 26, 2019.[24]


As of May 8, 2018, the Google Home was planned for release in Denmark, South Korea, Mexico, the Netherlands, Norway, Spain, and Sweden.[25]


On May 7, 2019, during the Google I/O keynote, Google announced that all of their smart home products will henceforth be marketed under the Nest brand.[26] Nest had been subsumed by Google's home hardware unit in July 2018.[27]


On July 10, 2019, a report published by Belgian broadcaster VRT NWS managed to gain access to more than a thousand audio excerpts recorded by Google Assistant in Belgium and the Netherlands.[28] The audio files were sent to Google employees to develop Google Assistant's speech technology. According to the VRT NWS report, 153 of the 1,000 audio files should have never been recorded and during which the command "OK Google" was clearly not given. In some cases, the recordings included "bedroom conversations, conversations between parents and their children, but also blazing rows and professional phone calls containing lots of private information".[29]


Google defended the practice in a blog post: "As part of our work to develop speech technology for more languages, we partner with language experts around the world who understand the nuances and accents of a specific language," Google wrote. "These language experts review and transcribe a small set of queries to help us better understand those languages. This is a critical part of the process of building speech technology and is necessary to creating products like the Google Assistant."[30]


In October 2021, the Google Home branding returned as a smart home platform for developers.[31]

Features[edit]

Google Assistant, an intelligent personal assistant, is included as the main and only assistant in Google Home.[71] Unlike its predecessor, Google Now, Assistant is able to engage in two-way conversations with users.[72] The Wall Street Journal reported in October 2016 that Google hired writers from Pixar movies and The Onion satirical newspaper to develop a personality for the Assistant, with a long-term goal being to invoke a sense of emotional rapport in users.[73][74][75]


Various forms of both in-house and third-party services are integrated into Google Home, allowing users to speak voice commands to control interaction with them. Examples of supported services include Google Play Music, Spotify and iHeartRadio for audio, Netflix, YouTube and Google Photos for videos and photos, Google Calendar and Google Keep for tasks, and CNN, CNBC, BBC and The Wall Street Journal for news updates.[76] New services are integrated on an ongoing basis.[77]


Users are able to connect and group together multiple speakers connected to or as part of Google Home for synchronized playback of music in every room.[78] A notable feature omission, multiple accounts, was criticized by JR Raphael of Computerworld in November 2016,[79] but an update for users in the United States in April 2017 enabled the feature. Google Home can recognize up to six different voices, pulling information from their different accounts depending on who's talking.[80][81][82] Google Home has integration with each user's calendar, for adding reminders or appointments verbally.


Google Home includes home automation features, enabling owners to use it as a central hub to control smart devices. Examples of supported devices include the Chromecast digital media player, and products from Nest, SmartThings, Philips Hue, LIFX, LightwaveRF,[83] and Logitech Harmony.[84]


In May 2017, Google announced multiple updates to Google Home's functionality. Google's speakers could now support hands-free calling, letting users make calls to any landline or mobile phone in the United States, Canada and later, the UK for free using a virtual number generated by google integrated into the device. In December 2021 an update to Google's Terms of Service restricted the feature of calling through Google Nest speakers to only numbers that are on the user's contacts.[85][86] Google Voice users can set Google Home with voice number to make personal and business calls.[87] There is no 9-1-1 emergency services support, however, Google Home users who live in the United States can subscribe to "Nest Aware". "Nest Aware" allows users to contact emergency call center located close to the residents home.[88] This security feature works when users are inside of the home and when you are away on vacation.[89] "Proactive Assistance" enables the device to dictate updates to users without being asked, including updates on traffic before a scheduled event.[90][91] "Visual Responses" let users send answers from Google Home onto their mobile device or Chromecast-enabled television.[90][92] The device now also supports Bluetooth audio streaming through compatible devices (including phones, tablets and computers),[93][94][95] and the ability to schedule calendar appointments, with upcoming support for reminders.[96]


On March 28, 2018, Google made the announcement via their blog that users would be able to pair any of their Google Home devices to their own Bluetooth speakers without requiring the use of a Chromecast streamer.[97]


On November 5, 2018, Google announced their partnership with Disney to bring interactive read-along books to Google Home.[98] In 2019, Apple, Google, Amazon, and Zigbee Alliance announced a partnership to make smart home products work together.[99]

Data storing and security methods[edit]

To use Google Assistant, a user of any Nest / Google Home device must register and sync an account using the Google Home mobile app. In the app, a setting allows the user to teach Google Assistant their voice. The Google voice technology can be used in digital forensics, where the words "OK, Google" are capable of unlocking mobile locks. A mobile device can be found, unlocked, and data can be extracted through the use of a suspect's voice file. "Hey Google" can also be used to wake up the device. Some features of Nest devices require the voice to be verified as to determine if the user is the owner. The device can also tell if it is connected to other smart devices, which can find stored data.[100]

Reception[edit]

Original Google Home speaker[edit]

The original Google Home received favorable reviews. The Google Home's design and sound input/output received significant praise, while a lack of interoperability between other Google Assistant-enabled devices was criticized. Critics also expressed concerns about Google's intentions with the device, particularly whether or not features would be more tightly integrated into other Google products.


David Pierce of Wired compared Google Home to Amazon Echo, writing in a summary that "Sometimes Home feels like sci-fi magic.[101] Sometimes it reaches beyond its grasp and falls flat. The Echo is less impressive, but more reliable". Pierce praised the look of Google Home, writing that it feels "minimalist, thoughtful, and warm" in the environment, and also praised its speaker, describing it as "richer, brighter and more dynamic than the Echo, and loud enough to fill a room". While noting that Home's use of the Google Assistant functioned in different ways than it does through the Allo app or Pixel smartphone, meaning quick instructions rather than longer tasks, he praised its search abilities, writing that "you’d expect Home to excel at search. It does", despite some wrong search hiccups. Pierce criticized its lack of interoperability with other Google Assistant-enabled devices, though he called its future potential for connecting information across Google's product lines "enormous".[101]


Ron Amadeo of Ars Technica praised Google Home's setup process and its ability to pick up voice commands even from a distance, calling the latter "absolutely incredible". He noted the device's limiting of its Bluetooth capabilities at the time (before the May 2017 update),[93] however, writing that "it's important to know that Google Home is not a Bluetooth speaker; it's purely a Google Cast device. If you want to play audio on a Google Home, the service needs to have a Google Cast button". He similarly criticized the Assistant's lack of cross-device functionality, writing that "Pretty much all the actions you send to a Google Home will stay on that Google Home, and there's never an interaction with your phone", and he noted concerns and questions regarding whether Google has an intention to incorporate the functionality deeper into its product lines. Additionally, in his summary, he wrote that "Why pay $129 for a device that is less capable than an Android phone?".[102]
