Fix Kokoro TTS integration - correct KPipeline API

- Removed model_path parameter (not supported by kokoro package)
- Removed repo_id parameter (causes KeyError)
- Use default KPipeline initialization with only lang_code
- Kokoro package handles model download automatically

Tested and working:
- American English voices (alloy, af_sarah, am_michael, etc.)
- British English voices (bm_george, bf_emma, etc.)
- Audio generation produces valid MP3 files

 **Original Notice:** This software was mostly obsolete and no longer updated by the original maintainer.
 
 **Raccoon Mission:** We're bringing it back to life with:
-- ✅ Working Piper TTS (tts-1) with absolute paths
-- ✅ Working XTTS v2 (tts-1-hd) with voice cloning
-- 🎯 Planning integration of 10+ abandoned TTS engines (Silero, StyleTTS2, Fish Speech, etc.)
+- ✅ Working Piper TTS (tts-1) - 55 voices, fast CPU inference
+- ✅ Working XTTS v2 (tts-1-hd) - 8 voices with cloning capability
+- ✅ Working Silero TTS (tts-1-silero) - 148 voices, 5 languages, CPU-friendly
+- ✅ Working Kokoro TTS (tts-1-kokoro) - 34 voices, lightweight decoder
+- 🎯 Next integrations: StyleTTS2 (best quality), Fish Speech (fast multilingual)
 - 📚 Comprehensive documentation in `docs/`
 - 🛠️ Makefile-driven deployment workflow
 - 🔒 AGPL v3 - keeps TTS libre forever

+## High Priority Integration Targets
+
+We're actively working on integrating these state-of-the-art TTS engines:
+
+  1. **StyleTTS2** ⭐⭐⭐⭐⭐
+     - Why: State-of-the-art quality, best prosody and naturalness
+     - License: MIT (permissive)
+     - Challenge: Complex dependencies (phonemizer), slower inference
+     - Priority: HIGH - Best quality available
+
+  2. **Fish Speech** ⭐⭐⭐⭐
+     - Why: Fast, modern, active development, good multilingual support
+     - License: Apache 2.0
+     - Challenge: Newer/less proven
+     - Priority: MEDIUM-HIGH - Good balance of quality and speed
+
+See [docs/MODELS.md](docs/MODELS.md) for the complete integration roadmap and detailed documentation on all supported and planned TTS engines.

 If you find a better voice match for `tts-1` or `tts-1-hd`, please let me know so I can update the defaults.
