Read Aloud (new "Vorlesen" tab):
- PDF (real page render + overlay highlight) / TXT reader with live word
highlighting, voice + speed, per-sentence synthesis-state colours, zoom
(fit-width/height, two-page, ±), resume, and a server-side book library
(syncs across devices; per-unit MP3 audio fetched on demand).
Book -> multi-speaker audiobook:
- "Cast as audiobook" attributes dialogue to characters via the LLM
(guillemet/quote-style aware, turn-taking, recent-context), with a
deterministic speech-tag fallback. Editable preview, non-blocking live
casting panel, then auto-saved as a reopenable Script Rehearser play.
- Audiobook export: synthesise every cast line -> one MP3 per chapter.
Character sheets:
- LLM-extracted, self-filling RPG-style sheets (with page+quote sources)
in both Read Aloud and the Rehearser.
Also: MP3 storage + per-page/sentence export, voice-library "Precompute
embeddings" pre-warm, German "Vorlesen" i18n + flag language toggle,
large-PDF performance (lazy raster, buffer/canvas eviction, yielded parse),
and the Seed Finder changelog entry.
New: routes/reader.py, POST /api/attribute-dialogue, POST /api/character-sheets,
static/js/{reader,audiobook,character-sheets}.js, static/sections/s-reader.html.

config/ and logs/ are now host directories visible on the filesystem.
- docker-compose.yml: ./config → /home/app/.config/tts-voice-creator:rw
./logs → /logs:rw
Named volume tts-voice-creator-clone-and-design-2 removed.
- portainer-stack.yml: same change with absolute host paths.
- server.py: RotatingFileHandler writes INFO+ to /logs/app.log
(maxBytes=5MB, backupCount=3). Falls back gracefully if /logs
is not writable.
- .gitignore: track config/ and logs/ dirs via .gitkeep but exclude
settings.json, *.log and backups from version control.
Benefits:
- Settings and logs are human-readable on the host at any time
- Survives docker-compose down -v (was lost with named volume)
- Easy backup: cp -r config/ logs/ to any destination
- Can edit settings.json directly if needed

- STT section now has a Quick test panel: select backend, hit mic button,
see transcript. Records via MediaRecorder, posts to /api/transcribe-bytes.
- _transcribe_audio detects the whisperx-gpu 'NoneType/to' error (caused by
pyannote/speaker-diarization-3.1 requiring a HuggingFace token) and
replaces it with an actionable message explaining how to fix it.
- _to_wav_16k added for STT audio conversion (Whisper/wav2vec2 expect 16kHz).
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
STT models (Whisper, WhisperX VAD, wav2vec2 alignment) all expect 16kHz.
Sending 24kHz caused whisperx's VAD to miss speech segments, leaving
alignment with None inputs → 'NoneType has no attribute to' crash.
Added _to_wav_16k() and use it in conversation/turn and transcribe-bytes
endpoints. Health check probe also uses 16kHz silence for consistency.

Port 8080 is Open WebUI — it passes /health + /v1/models checks but
returns 405 on POST /v1/audio/transcriptions. Updated probe logic to:
- treat 405 as 'endpoint missing, try next path'
- treat non-JSON 500 as broken, JSON-500 with detail as 'audio too short' (ok)
- use 500ms silence WAV instead of 1-frame (too tiny for alignment models)
Changed whisper.cpp default from :8080 to :8085 to avoid clash with
Open WebUI. Updated s-llms.html placeholder and code snippet accordingly.

_stt_backend_health now sends a minimal WAV to the transcription endpoint
after passing /health. A 500 response marks the backend unavailable,
catching containers that pass health checks but crash on model load (e.g.
CTranslate2 built without CUDA support).
Error messages from _transcribe_audio now include the backend URL and
replace generic 'Internal Server Error' with an actionable explanation.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
_transcribe_audio now extracts the response body on HTTP errors so the
actual cause (e.g. 'CTranslate2 not compiled with CUDA support') reaches
the user instead of '500 Server Error for url: ...'. Conversation panel
also strips the 'HTTP 500:' prefix to show only the meaningful part.

cardType() was defined inside initLlmsSection() IIFE but called from
renderLocalContainers() which is outside that scope, causing a silent
ReferenceError that reset every Connect click to failure. Moved cardType
to module scope.
Custom STT cards (e.g. whisperx-gpu) are now included in /api/stt-backends
and appear in the Conversation STT dropdown. Added _normalize_service_url()
so 0.0.0.0 URLs in stored cards are rewritten to host.docker.internal for
server-side health checks. _transcribe_audio() tries /transcribe as fallback
for custom backends that don't expose /v1/audio/transcriptions.

probe-url now accepts a type param (llm/stt/tts) and checks service-
specific endpoints: LLM → /v1/models with data[] key, STT → /health
then /v1/models, TTS → /health then /voices endpoints. Random websites
and wrong services are now rejected. Connect passes the card's section
type; success toast shows which endpoint responded.

Replaces the filter-to-available-only approach with full lists that
include unavailable backends (disabled, marked ✗) so users can see
what's broken. Also extends STT retry fallback to cover HTTP 500 from
wrong model names (fixes faster-whisper CTranslate2 CUDA build issue).

Engine URL inputs (Ollama, vLLM, faster-whisper, etc.), custom engine
cards, and the refinement/conversation LLM URLs were stored only in
localStorage and lost on browser data clear. All four are now synced
to settings.json via _patchSettings() with localStorage as fast
initial fallback.

Parakeet RNNT NIM measured at 550–605 MB (unified RAM), Magpie TTS at
982 MB, and Qwen3-TTS model at 4.3 GB on disk — replacing the placeholder
estimates that were too high across the board.

New TTS backend: Kokoro FastAPI (82M) — OpenAI-compatible, 11 built-in
voices, only shows when server is reachable (~300 MB CPU, ~0.1× RTF).
New STT backends in Transcribe dropdown: faster-whisper (CTranslate2 GPU,
~70× RT, 1.5 GB VRAM), whisper.cpp (CPU/CUDA, ~8–15× RT, ~1 GB RAM),
Groq Whisper (fastest cloud, free 2 000 req/day, key shared with Groq LLM).
Backend help panels now show ⚡ speed · ⏰ latency · ⭐ quality · 💾 RAM
metric chips for all TTS and STT backends.
Active Docker Stack cards also get per-container metric chips.
AI Backends section: "Use as STT" / "Use as TTS" one-click buttons on
faster-whisper, whisper.cpp, and Kokoro cards apply URLs to Settings
without leaving the page. Groq Whisper card notes the shared key path.
Settings: Kokoro URL in TTS cluster; faster-whisper URL, whisper.cpp URL,
Groq API key in STT cluster; quick-fill buttons for all local STT engines.
