Google Nest (smart speakers)


Google Nest, formerly known as 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, and with a touchscreen display on some models. 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

In March 2016, reports were published about Google developing a wireless speaker to compete against the Amazon Echo. Google Home was officially announced at the company's developer conference in May 2016, where it was also announced that Home would run the Google Assistant.
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. The Google Home smart speaker was released in the US on November 4, 2016, and in the UK on April 6, 2017. In May 2017, Google announced that Home would be heading to Australia, Canada, France, Germany, and Japan in middle 2017, and the device subsequently became available for pre-order in Canada on June 2, 2017, with a retail date of June 26. In July 2017, Google announced the release of Google Home in Australia on July 20, 2017, France on August 3, 2017, Germany on August 8, 2017, and Italy on March 27, 2018.
On October 4, 2017, Google announced Google Home Mini, a smaller, less expensive variant that was released on October 19, 2017, as well as Google Home Max, a larger, more expensive variant that was released on December 11, 2017.
The Google Home and Home Mini were released in India on April 10, 2018, and the Nest Hub was released on August 26, 2019.
As of May 8, 2018, the Google Home was planned for release in Denmark, South Korea, Mexico, the Netherlands, Norway, Spain, and Sweden.
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. Nest had been subsumed by Google's home hardware unit in July 2018.
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. 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".
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."

Models

Google Home

The original Google Home model is a cylindrical speaker that is tall and in diameter. The top surface of the device features colored status LEDs, and features capacitive touch controls to start and stop music, and adjust volume. A mute button is located on the back of the device, which disables the microphones.
The base of the device is covered by a shell acting as a speaker grille, which is designed to be removed and replaced with one that suits the decor of a room., Google offers fabric shells in "Mango", "Marine", and "Violet" color finishes, and metallic shells in "Carbon", "Copper", and "Snow" finishes.
The Information reported that Google Home's internal hardware was very similar to that of the Chromecast, with the same ARM processor and Wi-Fi chip. In November 2016, a teardown of the original model by iFixit confirmed that the device featured many of the same hardware components as the second-generation Chromecast.

Home Mini

Google unveiled the Google Home Mini during a hardware-focused event on October 4, 2017, which was released on October 19, 2017. It is a variant of Google Home with the same overall functionality, but in a smaller pebble-like form factor around 4 inches in diameter, with a fabric top that its white-colored status lights shine through. It has a mute switch rather than a mute button, and uses a micro USB connection for power. It is available in the colors "aqua", "chalk", "charcoal", and "coral". Analysts compared the Google Home Mini to Amazon's equivalent Echo Dot model.
Prior to its release, a "phantom input" bug was discovered, where its touch-sensitive surface—which could be tapped to activate Assistant without using a hotword command—inadvertently activated on its own, resulting in unwanted voice recording. Due to privacy concerns, Google removed the feature entirely from all units via a software update. In December 2017, Google released an update to Home Mini, allowing users to long-press the volume buttons to play and pause audio.

Home Max

During its October 4, 2017, event, Google unveiled the Google Home Max, which was released on December 11, 2017. It is a larger version of the Google Home device with stereo speakers, an audio connector, and a USB Type-C connector intended for a wired Ethernet adapter. It was released in the colors "chalk" and "charcoal", and has a magnetically attached stand for vertical orientation, and "Smart Sound", an adaptive audio system that uses machine learning to automatically adjust sound output based on factors such as the environment and time of day. Reviewers compared the Home Max to Sonos smart speakers and Apple's HomePod. The Google Home Max was discontinued from sale on December 14, 2020.

Home Hub / Nest Hub

On October 9, 2018, Google unveiled the Google Home Hub, which features a 7-inch touchscreen display that can be used to provide visual feedback for queries. The "Home View" feature provides a centralized, visual interface for controlling supported smart home devices and Nest video cameras. Unlike its closest competitor, the Amazon Echo Show, the Home Hub does not include a camera for video calls, citing customer privacy concerns. Although Google has developed an OEM solution for Assistant-powered smart display devices based on Android Things and a Qualcomm system-on-chip, the Home Hub utilizes a different hardware platform. The device is available in light gray, dark gray, pink, and aqua blue. A reported security issue in the Home Hub was dismissed by Google as a non-issue, as an attack would require access to the same Wi-Fi network as the device.
On May 7, 2019, the Google Home Hub was rebranded and renamed to the Google Nest Hub.
On May 25, 2021, an update for the Preview Program released to the first generation model replaced the Linux-based Cast OS with Google Fuchsia, becoming the first commercial device to ever feature the operating system.

Second generation

On March 30, 2021, a second generation of the Google Nest Hub was released. The second generation sported 50% more bass and a sleep sensor. The Nest Hub kept its 7-inch touchscreen.

Nest Hub Max

A larger version of the Google Nest Hub, called the Google Nest Hub Max, was announced on May 7, 2019. It features a 10-inch display, integrated camera, and larger speakers with a rear-facing subwoofer. It was released in September 2019.

Nest Mini

On October 15, 2019, Google unveiled a second-generation model of the Home Mini branded as the Google Nest Mini. It was released on October 22. The device is similar in design to the first-generation Home Mini with several small improvements. The fabric of the Nest Mini is made of recycled consumer plastic bottles. The device is powered by a proprietary pin-style DC plug with higher energy input and reliability than the previous iteration's Micro-USB. The upgrades include a larger speaker, an additional microphone, a machine learning chip that can cache voice recognition data for commonly used commands locally. It contains LED lights that highlight the touch areas for volume control and makes use of "ultrasound sensing", allowing for findability in dark environments. The bottom of the Nest Mini contains a hole for wall-mounting with a screw. It is available in the colors "chalk", "charcoal", "coral", and "sky blue".
