What replaces a smart speaker?
Home Assistant Assist is a voice assistant built into Home Assistant. It interprets spoken requests to control devices and run home automations. You need a way to speak to it—a physical endpoint with a microphone and speaker, or a compatible phone or computer. Home Assistant calls these endpoints “voice assistant satellites.”
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsAssist is best understood as a home-control interface. The documentation establishes voice control and spoken responses, but does not establish parity with consumer assistants for general-knowledge answers or integrated music services. If those features are central to how you use your current speaker, check that each specific function is supported before replacing it.
#1 Best Overall

Which endpoint should you choose?
| Option | What it offers | What to weigh |
|---|---|---|
| Home Assistant Voice Preview Edition | Ready-made Assist endpoint with a setup wizard and physical microphone mute. Home Assistant lists a recommended MSRP of $69 USD, excluding taxes. | Designed around Assist; local speech features depend on language and backend. Home Assistant says prices vary by region and retailer, so the MSRP is not a live Amazon price. |
| ESPHome/ESP32 DIY satellite | A build-it-yourself route using an ESP32 microcontroller and ESPHome. Home Assistant’s Assist overview links to a tutorial with a stated $13 build figure. | Assembly and configuration are required. The tutorial figure is not a verified current parts basket or a guaranteed total; microphone and speaker quality depend on the parts selected. |
| Linux Voice Assistant satellite | A more customizable software endpoint for x64 or ARM64 hardware, with local wake-word options and a prebuilt Raspberry Pi image. | The project is marked experimental and requires compatible hardware and configuration. Follow its current installation guidance. |
The Voice Preview Edition figure and tutorial build figure describe different things, not directly comparable packages. The $69 figure is a recommended US MSRP before tax; the $13 figure is the tutorial’s stated build cost. Neither establishes the lowest universal entry price or total cost for a complete setup.
What does fully local voice processing mean?
In Home Assistant’s fully local configuration, speech is processed on your own hardware and spoken commands do not leave the home. The pipeline needs microphone input, speech-to-text (STT), Home Assistant intent processing, and text-to-speech (TTS). Local processing is a configuration choice; buying a Voice Preview Edition endpoint alone does not guarantee it.
Rank #2
- Designed for Home Assistant Voice & Music Workflows: Preloaded with Home Assistant Voice Assistant and Music Assistant. Functions as both a voice input terminal and an audio playback endpoint.
- Dual Microphones for Voice Capture: Built with dual digital microphones for wake word or button-activated voice capture. Audio is streamed to the Home Assistant voice pipeline.
- Integrated 3W Speaker for Direct Playback: The built-in 3W/4Ω speaker supports TTS playback, Music Assistant streaming, and system audio without external speakers.
- Linux-Based Local Operation: Runs a lightweight Linux system on a quad-core ARM A53 CPU with 256MB RAM and 512MB flash for local audio processing.
- Development & Debugging Capabilities: Supports firmware flashing, and also provides access to live logs, on-device editing—suitable for routine development or issue diagnosis.
Home Assistant documents two local STT approaches with different trade-offs:
The Tool Desk
Outbyte PC Repair FREEClear out junk files and repair common Windows errorsFree Scan →Outbyte Driver Updater FREEFix the driver behind crashes, sound loss and screen glitchesFind Drivers →- Speech-to-Phrase: Home Assistant says it can process speech in under one second on Home Assistant Green or Raspberry Pi 4. That is the official guide’s performance statement, not an independent benchmark. It handles only a subset of Assist commands, so it may not suit varied or open-ended requests.
- Whisper: A more general local STT option, but Home Assistant says it needs more processing power for responsive, accurate results. Actual performance depends on the hardware and configuration.
Home Assistant also documents Piper for local TTS. Language support varies across local speech components, so verify that your preferred language is supported by the specific pipeline you intend to use. Home Assistant Cloud is an optional cloud-based STT/TTS route, including for cases where local language or hardware support is unsuitable; choosing it means speech processing is not fully local.
Rank #3
- Please note!!! This product requires a 3.7V MX1.25 lithium battery for operation, which is not included. Please purchase it separately.
- High-Performance MCU: The board is equipped with the ESP32-S3R8 module, featuring a powerful Xtensa 32-bit LX7 dual-core processor that operates at up to 240MHz, ensuring efficient processing for various smart applications.

How do the DIY paths differ?
ESPHome and ESP32
The ESP32 route is aimed at people willing to assemble and configure a small endpoint. Home Assistant’s overview links to a tutorial whose stated build figure is $13, but that figure should not be treated as a current universal cost: parts, shipping, taxes, and any substitutions can change the total. Check the tutorial’s present parts list and ensure the selected hardware meets your needs for microphone and speaker quality.
Linux Voice Assistant
Linux Voice Assistant is the more flexible option if you already have compatible x64 or ARM64 hardware and want local compute or configuration choices. Its upstream project describes it as experimental. It offers local wake-word detection and a prebuilt Raspberry Pi image; it can also be installed as a Home Assistant OS Assist Satellite app after manually adding the project’s app repository.
Rank #4
- ESP32-S3-AUDIO-Board adopts ESP32-S3R8 module with 32-bit LX7 dual-core processor, up to 240MHz main frequency. Supports 2.4GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5 (LE), with onboard antenna
- Integrated 512KB Static RAM, 384KB ROM, 8MB PSRAM, and external 16MB Flash memory. Onboard TF card slot for storing audio files, etc.
- Onboard Dual microphone array with noise reduction and echo cancellation, suitable for accurate speech recognition and near/far-field wake-up. Onboard audio decoding chip, dual microphones and speaker header. Onboard 7x surround RGB LEDs, programmable for a variety of dynamic effects
- Onboard SPI LCD display interface (FPC connector / pin header), DVP camera interface (24pin connector), USB, I2C, and some I/O pins (compatible with display interface I/O pins). Onboard multiple reserved buttons and battery switch for customized function development
- Integrated PCF85063 RTC chip, supports power-off time retention for alarm, scheduled task, and wake-up functions. Built-in battery recharge management module, supports multiple power modes and low-power applications
Do not start a new build from the older Wyoming Satellite repository as though it were the current software: that repository is deprecated and says it has been replaced by Linux Voice Assistant. Its Raspberry Pi Zero 2 W and ReSpeaker 2Mic HAT instructions document a historical parts path, not a guarantee of current software support.
How to decide whether switching is worth it
- Start with your use case: List the commands and features you rely on. Assist is supported as a home-control assistant; do not assume it replaces general answers or music integration.
- Choose the endpoint: Voice Preview Edition is the documented ready-made path. ESP32 and Linux options trade setup simplicity for DIY flexibility or local compute.
- Choose a speech pipeline: Decide between constrained, quick Speech-to-Phrase and more hardware-intensive Whisper, or use optional cloud speech services where appropriate.
- Compare full costs: Count the endpoints you need, all hardware and shipping, taxes, and any recurring services. Compare those against the actual cost of the speakers you would otherwise buy or keep.
- Test before replacing everything: Set up one endpoint and check command coverage, language support, latency on your hardware, and whether the privacy settings match your expectations.
Without actual old-device costs, complete new-build costs, and any recurring charges, there is no substantiated savings figure. Likewise, official setup descriptions are not a like-for-like setup-time or reliability comparison. Home Assistant describes Voice Preview Edition as easy to set up, while DIY options require building or configuration; your experience will depend on the route and your existing Home Assistant setup.
