Google has released the Google Home Speaker, its first smart speaker built around the Gemini for Home voice assistant. Priced at 99.99 USD (about 16,000 yen), it went on sale on June 25 in 18 countries, including Japan. The device runs AI on a dedicated on-device chip for faster responses, yet its headline conversational feature turns out to require a paid subscription. Here we walk through the hardware, the day-to-day experience, and the pricing.

A first speaker built around "Gemini for Home"

The Google Home Speaker is the first stationary speaker to carry "Gemini for Home," Google's version of its Gemini AI tuned for the household. First shown at the "Made by Google" event in August 2025 and detailed further through that October, the product has finally reached the market.

It launched on June 25 across 18 countries, including the United States, Canada, the United Kingdom, and France. Japan is among them, so it can be bought domestically. The Porcelain (white) and Hazel (gray) colors are available worldwide, while the green Jade and reddish Berry are exclusive to the US Google Store. Pre-orders opened ahead of the release.

On-device AI for faster responses

The biggest feature is an "on-device" design that completes AI processing inside the unit itself. Earlier Nest speakers had to reach the cloud for every voice command, but the Google Home Speaker runs a compact AI called "Gemini Nano" on the device. As a result, standard voice commands are said to respond in under 0.1 seconds (100 milliseconds), a sharp cut from the several hundred milliseconds of cloud-based predecessors.

Handling this is a quad-core 2.0 GHz "A55" CPU paired with a dedicated NPU (AI accelerator) for AI computation. It carries 1 GB of RAM and 4 GB of storage. Connectivity covers Wi-Fi 6 (802.11ax, 2.4 GHz / 5 GHz) and Bluetooth 5.4, plus a border-router function for the smart-home networking standard Thread 1.3.

Better sound and controls

On the audio side, Google touts 360-degree sound, with a driver 2x larger (58 mm) than the compact Nest Mini and 2.5x stronger bass. It has three far-field microphones that pick up distant voices, and they can be switched off with a physical toggle.

A light ring at the base uses moving light to show when Gemini is listening, thinking, or responding. The top surface has three touch-control areas: the left and right adjust volume, while a tap in the center toggles play and pause. The device measures 4.2 inches (about 10.7 cm) in diameter and 3.4 inches (about 8.6 cm) tall, and it uses a non-detachable 1.5 m cable with a USB-C 30 W adapter. Pairing two units enables stereo playback, and combining it with the "Google TV Streamer" adds spatial surround sound. It can also be grouped with existing Nest speakers and displays, as well as other Cast-enabled devices.

The advanced conversation feature needs a subscription

One thing to watch: using "Gemini Live," which enables natural, real-time conversation, requires a paid "Google Home Premium" subscription. The unit comes with six months of Google Home Premium (a 60 USD, roughly 9,700 yen value), but only for units purchased before September 30. To keep using the advanced conversational features after the free period ends, you will need to continue the subscription. Fast responses via on-device processing are available as a standard feature, but the conversational experience that is arguably the main selling point comes at an added cost.

Summary

The Google Home Speaker is Google's first speaker, built around Gemini for Home and on-device AI to improve both response speed and sound quality. Its accessible 99.99 USD price and broad availability, including Japan, are appealing, but the fact that its centerpiece "Gemini Live" is effectively subscription-gated is worth knowing before you buy. A sensible approach may be to use the bundled six-month free period first to gauge how well it fits your home.
