HiveMind Voice Satellite

The full-stack OVOS voice satellite: microphone, VAD, wakeword, STT, and TTS all run on this device. Spoken input is transcribed locally; only the resulting text utterance is sent to the hive. Responses arrive as text and are spoken locally. Requires the most compute of the satellite family, but puts the least load on the server and works fully offline once set up.

Satellite spectrum

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

Install

pip install HiveMind-voice-sat
# Linux — ALSA/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.
