Jarvis voice, offline: paste your Fish Audio key and the voice's page address below, save, then tap Download Voice Pack. That generates every line once and stores the audio on this phone — after that Jarvis speaks instantly with zero API calls, even with no signal.
Traffic & routes: paste a free TomTom key (from developer.tomtom.com) to enable spoken traffic reports and route checks. Weather needs no key.
Spotify auto-play (Premium): at developer.spotify.com/dashboard create an app, set its Redirect URI to this page's address, then paste the app's Client ID here, Save, and tap Connect.
Optional — ElevenLabs (used live when no voice pack and no Fish key):
Driver: how the assistant addresses you on this phone. Set it once per device.
