FAST audio response to action

Right now I’m using Alexa’s (echos) around my house to give some audio feedback for doors opening or closing… however it’s not quite good enough for my preference.

My problem with this technique comes down to a few things

  1. The latency to initiate the sound is too high.
  2. The synchronization between devices doesn’t work well at all.
  3. Stopping or interrupting something the echo was already doing… like playing music.

What I’d like to emulate is a independent hard wired security systems that beeps or verbally announce a door or window opening (“garage”, or “front door”, or just a “beep beep”) And of course other notifications too.

My question really comes down to, what would be the best option to play an audio file on designated devices nearly instantly, in near perfect synchronization throughout the house?

Example of what I’m doing now:

alias: Sliding Glass Door Closed
description: ""
trigger:
  - type: not_opened
    platform: device
    device_id: -omitted-
    entity_id: binary_sensor.lumi_lumi_sensor_magnet_aq2_on_off
    domain: binary_sensor
condition: []
action:
  - service: notify.alexa_media
    data:
      message: >-
        <audio
        src='https://mpndvguqlew9bav4iku1ta4rn9556xde.ui.nabu.casa/local/media/sounds/back-door-closed.mp3'/>
      target:
        - media_player.joe_s_2nd_echo_show
        - media_player.bathroom_echo_show
        - media_player.office_echo_show_5
      data:
        type: tts
mode: single

What happens now, is somewhere between 1 and 5 seconds, the 3 amazon echo’s start playing a sound effect, and they are sort of scattered over about 1-2 second in not really in sync.

My hope is to find a system I can use that will work to play short sounds or TTS announcements:

  1. Nearly instantly. Like a switch’s tactile feedback or as low latency as possible.
  2. Preferably wirelessly.
  3. Preferably multiple devices that I can define which ones to address depending on the automation

I don’t mind buying a handful of devices to scatter around my house, but they need to outperform having an amazon echo announce things a few seconds late.

Does anyone have any ideas?

Did you ever find a way to achieve this?

No. I’ve considered adding a more centralized amplifier to the house and running smallish speakers in each room. This way all audio for announcements / tones would be from a single source.

I have no idea the cost right now, but something like this comes to mind:

Daisy-chaining would be great if I have to hardwire things to get the latency down to zero. There are a lot of hard wired solutions that are home run style for each zone which I could also do.

It’s been a few years, I’m curious if anyone has found an out of the box solution to this?

Moved into a new house and previous I used Sonos for door chimes, and it was instant but my wife didn’t like it because it used our TV speaker so felt a bit janky.

So now in the new house it’s a blank slate, and I heard everyone recommend Google Homes for door chimes but…the latency and synchronicity of them is awful.

I feel like there has to be an out-of-the-box speaker with HA-compatibility that doesn’t have a huge delay to make sounds.
