 ## 19. Recommended Future Additions
 
 If the project grows further, the next useful additions to this document are:
+- optional neural TTS provider integration for natural start, finish, and driver-name announcements
+- backend-only provider credentials with no API key material in frontend state, exports, or public overlays
+- server-side speech generation and content-addressed cache under `data/tts/` so race playback never waits for a cloud request
+- cached audio invalidation when language, voice, phrase, or a driver's `speechName` changes
+- offline fallback order: cached neural audio -> uploaded WAV/MP3 -> browser system voice -> passing beep
+- provider health/status and a pre-generate-all-names action in Settings before race day
 - exact `resultsBySession` competitor row schema
 - exact `settings` schema snapshot
 - SQLite table contract section
