ai voice assistants

Build a private, offline Linux voice assistant that launches apps, controls audio, and runs shell commands using open‑source tools. This hands‑on guide readies your audio stack, delivers a 10‑minute Vosk + espeak‑ng setup, upgrades accuracy with Whisper.cpp, shows wake‑word options, real CLI integrations, and troubleshooting, then maps next steps like better TTS and Home Assistant—all without cloud, telemetry, or subscriptions.
