Overview

Overview

SGT Smart Speakers are multi-room voice-controlled speakers that double as the household’s control hub for music, news, calendar, smart-home scenes and reminders — in English, Bengali, Hindi or Urdu.

A 3-mic far-field array hears you across the room over playing music, the wake-word runs entirely on the speaker (so the cloud only ever sees commands you actually said to it), and the system pairs into stereo or links into a synchronised multi-room mesh that streams the same source to every speaker with < 20 ms drift. Ask for the weather, schedule a reminder, set a scene, dim the lights or play your morning lo-fi playlist — one device handles all of it.

  • Multi-room sync — same source across every speaker, < 20 ms drift
  • Far-field 3-mic array — hears wake-word over music at 88 dB SPL
  • On-device wake-word — cloud only sees what you actually meant for it
  • Scene triggers — “Hey SGT, good morning” runs your whole wake-up routine

How It Works

The diagram above traces a voice command from the mic array, through the local wake-word and the cloud’s NLU, back to the speaker (and every other speaker in the same group). Hover any module to see its live telemetry.

  1. The speaker — cylindrical unit with 360° tweeter, down-firing woofer, 3-mic top array and a colour LED status ring.
  2. Voice & intent — 4-stage pipeline: on-device wake, cloud ASR, NLU intent extraction, then an action (play / scene / answer).
  3. Cloud services — music (Spotify, YouTube, Tidal), calendar, weather, news, plus the smart-home bridge to lights, AC, curtains and plugs.
  4. Multi-room & family — stereo pair, party mode (all rooms), per-room volume; 4 voice profiles so calendar replies are personalised.

The violet stream along the bottom is the live sync channel — TTS responses, scene fires and multi-room timing flowing between every speaker.

Features

  • Far-field 3-mic array with beam-forming & echo cancellation
  • On-device wake-word — mic stays local until you address it
  • Hardware mic mute — physical switch cuts mic power, LED goes red
  • Multi-room sync — < 20 ms drift across any number of paired speakers
  • Stereo pair — two units in the same room become a left/right pair
  • EN / BN / HI / UR wake-word and intent support
  • Calendar & reminders — replies in your own voice profile
  • Smart-home scene triggers — “movie night”, “good morning”, “bedtime”
  • AirPlay 2, Spotify Connect, Bluetooth 5.0, Wi-Fi 6 input options
  • Adaptive EQ — auto-tunes bass / treble to the room acoustics

Use Cases

  • Morning routine — “Good morning” raises blinds, dims warm lights, plays news brief
  • Whole-house music — same playlist in living room, kitchen and bedroom
  • Hands-free cooking — set timers, convert units, ask recipe questions
  • Family calendar — “What’s today?” replies with the asker’s own calendar
  • Movie night — single phrase dims lights, closes curtains, mutes speakers
  • Late-night quiet mode — auto-volume drop after 22:00 in bedrooms
  • Reminders for elderly — spoken medication reminders multiple times a day
