HiveMind Voice Satellite

HiveMind Voice Satellite is a full-stack OVOS voice satellite. Microphone capture, VAD, wakeword detection, STT, and TTS all run on this device. The satellite transcribes speech locally and sends only the resulting text utterance to the hive. Responses arrive as text and the satellite speaks them locally. This satellite needs the most compute of the satellite family. It puts the least load on the server and works fully offline once set up.

Satellite spectrum

Satellite	Mic	VAD	Wakeword	STT	TTS	What crosses the wire
HiveMind-cli	n/a	n/a	n/a	n/a	n/a	text in / text out
hivemind-mic-satellite	local	local	n/a	remote	remote	raw audio stream
HiveMind-voice-relay	local	local	local	remote	remote	audio after wakeword
HiveMind-voice-sat ← you are here	local	local	local	local	local	text utterances only

Use voice-sat when the device has CPU/GPU to spare, bandwidth is limited, or audio privacy matters.

Install

pip install HiveMind-voice-sat
# Linux: ALSA or SoundDevice microphone support
pip install HiveMind-voice-sat[linux]
# macOS
pip install HiveMind-voice-sat[mac]

60-second quickstart

1. Add a client on the hive (run this on the server):

hivemind-core add-client --name my-voice-sat
# outputs: Access Key and Password, copy them

2. Run the satellite (on this device):

hivemind-voice-sat --host <hive-host> --key <access-key> --password <password>

Say your wakeword. The satellite transcribes locally and sends the utterance to the hive.

Minimal configuration

The satellite reads ~/.config/mycroft/mycroft.conf (standard OVOS config). Override STT, TTS, VAD, and wakeword plugins there:

{
  "listener": {
    "VAD": {
      "module": "ovos-vad-plugin-silero"
    },
    "wake_word": "hey_mycroft",
    "hey_mycroft": {
      "module": "ovos-ww-plugin-vosk"
    }
  },
  "stt": {
    "module": "ovos-stt-plugin-server",
    "ovos-stt-plugin-server": { "url": "https://stt.openvoiceos.org/stt" }
  },
  "tts": {
    "module": "ovos-tts-plugin-server",
    "ovos-tts-plugin-server": { "host": "https://tts.openvoiceos.org" }
  }
}

All plugin slots are swappable via ovos-plugin-manager. See docs/configuration.md for the full reference.

Development

git clone https://github.com/JarbasHiveMind/HiveMind-voice-sat
cd HiveMind-voice-sat
pip install -e ".[test]"   # lightweight smoke deps
pytest tests/test_smoke.py
pip install -e ".[e2e]"    # full hivemind-core + 2.x stack for end-to-end
pytest tests/e2e/

pyproject.toml is the single packaging source of truth. The dependency stack now runs on ovos-bus-client 2.x (see docs/architecture.md). Prerelease dependencies are pinned as minimum versions, so pip resolves them without --pre.
