 Player-facing speech uses Piper TTS in WebAssembly in the browser after audio is activated by a user gesture. It reads game dialogue, onboarding, account responses, character and world creation, gameplay replies, in-game errors, and microphone disclosures; the `/admin` route is excluded. The audio is decoded and played through the Web Audio API, independently of `speechSynthesis`. The first unauthenticated visit keeps the introduction visible and it can be started with `Läs introduktionen`. New game replies are read automatically and the transcript remains available to screen readers and as text. Returning players hear the latest saved game reply when they reopen the game. The player can change speaking rate; narrator pitch is neutral and character pitch is varied consistently by voice identity. These preferences are stored in browser `localStorage`. If WebAssembly, model loading, or audio playback fails, the same content remains available as text and the dialogue offers a retry.
 
-The Piper engine, WebAssembly runtime, and all three Swedish medium voice models (Alma, Lisa, and NST) are served from this frontend's same-origin `/tts/piper-wasm-v1/` path. The Gitea pipeline downloads the pinned model files, verifies their sizes and cryptographic hashes, and packages them into the versioned frontend image. The browser's Piper adapter redirects the library's built-in model URLs to this same-origin server; it does not request voice files from Hugging Face. A voice model is fetched on first use and cached in browser storage when supported. The game currently uses the NST model. Dialogue text is synthesized on the device and is not sent to a TTS provider. Voice model attribution and license references are available in the voice settings and at `/tts/piper-wasm-v1/voices/ATTRIBUTION.txt`.
+The Piper engine, ONNX WebAssembly runtime, and all three Swedish medium voice models (Alma, Lisa, and NST) are served by the separate `ai-spel-static` Nginx service from same-origin `/static/piper-wasm-v1/`. Its own Gitea pipeline downloads pinned models, verifies sizes and hashes, and publishes a versioned image and Helm chart independently from frontend changes. The frontend's Piper adapter redirects the library's built-in model URLs to this static service; it does not request voice files from Hugging Face. Voice models are fetched on first use and cached in browser storage when supported. Dialogue text is synthesized on the device and is not sent to a TTS provider. Attribution is available at `/static/piper-wasm-v1/voices/ATTRIBUTION.txt`.
 
 The microphone button beside the text field uses Web Speech API when available and sends only its final Swedish transcript through the same submission path as typed text. Before its first use, the client explains that the browser may process audio through a provider-selected service; the game itself does not receive or store recordings, while the final transcript is saved as ordinary dialogue. Writing `röstinställningar` or saying `röstkommando alternativ` opens temporary voice controls in the dialogue. The player can adjust speaking rate and enable or disable short audio cues. Voice preferences are stored in browser `localStorage`.
