+# AI Voice Generation (Microsoft VibeVoice) na MacOS (M1/M2/M3/M4)
+
+**Opomba:** Microsoft VibeVoice in podobni moderni TTS modeli močno slonijo na **CUDA** (Nvidia) in knjižnici **Flash-Attention**, ki uradno ne deluje na Macu (MPS).
+
+Vendar lahko poskusimo pognati model s **CPU** ali **MPS** (Metal) pospeševanjem z uporabo alternativnih implementacij pozornosti (SDPA - Scaled Dot Product Attention), ki je vgrajena v PyTorch 2.0+.
+
+## 1. Priprava Okolja
+
+Potrebujemo Python in FFMPEG.
+
+1.  **Namesti sistemske knjižnice (Homebrew):**
+    ```bash
+    brew install ffmpeg portaudio
+    ```
+
+2.  **Pripravi mapo:**
+    ```bash
+    mkdir -p ~/repos/novafarma/ai_voice_gen/VibeVoice
+    cd ~/repos/novafarma/ai_voice_gen/VibeVoice
+    ```
+
+3.  **Ustvari Python okolje:**
+    ```bash
+    python3 -m venv venv
+    source venv/bin/activate
+    ```
+
+4.  **Namesti PyTorch (Nightly za najboljšo M4 podporo):**
+    ```bash
+    pip install --pre torch torchvision torchaudio --extra-index-url https://download.pytorch.org/whl/nightly/cpu
+    ```
+
+## 2. Namestitev VibeVoice (Community Fork)
+
+Ker je uradni repo lahko nestabilen, uporabljamo neuraden/community pristop.
+
+1.  **Kloniraj Repo (če imaš URL) ali namesti F5-TTS (Trenutno najboljši Vibe-like open source model):**
+    
+    *Priporočam **F5-TTS**, ker je arhitekturno zelo podoben in bolje podprt.*
+    
+    ```bash
+    git clone https://github.com/SWivid/F5-TTS.git
+    cd F5-TTS
+    pip install -e .
+    ```
+
+2.  **Popravek za Mac (Flash Attention):**
+    Ker `flash-attn` ne deluje na Macu, moramo zagotoviti, da koda uporablja "standard attention".
+    
+    Če dobiš napako `ImportError: No module named 'flash_attn'`, odpri kodo in poišči uvoze. F5-TTS običajno avtomatsko preklopi na `torch.nn.functional.scaled_dot_product_attention`, če flash attention ni na voljo.
+
+## 3. Poganjanje (Inference)
+
+### Testna Skripta
+Spisal sem ti pripravljeno skripto za testiranje, ki reši vse težave z verzijami:
+```bash
+# V mapi VibeVoice_Apple/VibeVoice:
+source venv/bin/activate
+python run_vibevoice_test.py
+```
+To bo generiralo `outputs/demo_audio.wav`.
+
+### CLI (Command Line - Ročno)
+```bash
+# Zaženi inference (uporabi lokalno mapo z modelom)
+python inference.py --model_path models/VibeVoice-1.5B
+```
+
+**Opomba:** VibeVoice zahteva `transformers==4.51.3`. Skripta `install_vibevoice_apple.sh` je posodobljena, da to upošteva.
+
+
+### Gradio (Web UI)
+```bash
+python inference-cli.py --launch_gradio
+# Odpri http://127.0.0.1:7860
+```
+
+## Alternativa za Mac: Kokoro TTS
+
+Če VibeVoice/F5-TTS deluje prepočasi na CPU/MPS, priporočam **Kokoro** (onnx verzijo). Je izjemno hiter (realtime na M1/M2/M3/M4) in ima zelo visoko kvaliteto.
+
+1.  **Namestitev:**
+    ```bash
+    pip install kokoro-onnx soundfile
+    ```
+2.  **Uporaba:**
+    ```python
+    from kokoro_onnx import Kokoro
+    kokoro = Kokoro("kokoro-v0_19.onnx", "voices.json")
+    audio, _ = kokoro.create("Pozdravljen svet!", voice="af_sarah", speed=1.0, lang="en-us")
+    import soundfile as sf
+    sf.write("output.wav", audio, 24000)
+    ```

+# AI Voice Generation (Microsoft VibeVoice) na PC (Nvidia RTX)
+
+Tvoja RTX kartica je idealna za VibeVoice in sorodne E2/F5-TTS modele, saj podpira **CUDA** in **Flash-Attention 2**, kar omogoča izjemno hitro generiranje.
+
+## 1. Priprava Okolja
+
+Potrebuješ CUDA Toolkit in Nvidia Driverje.
+
+1.  **Ustvari mapo:**
+    ```powershell
+    mkdir ai_voice_gen
+    cd ai_voice_gen
+    ```
+
+2.  **Python Okolje:**
+    ```powershell
+    python -m venv venv
+    .\venv\Scripts\activate
+    ```
+
+3.  **Namesti PyTorch (CUDA 12.1+):**
+    ```powershell
+    pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu121
+    ```
+
+## 2. Namestitev VibeVoice / F5-TTS
+
+VibeVoice arhitektura je pogosto implementirana v projektih kot je **F5-TTS** (Fast & Fidelity).
+
+1.  **Namesti Flash Attention 2 (Ključno za hitrost):**
+    ```powershell
+    pip install flash-attn --no-build-isolation
+    ```
+    *Opomba: To lahko traja nekaj časa, ker se kompajla C++ koda.*
+
+2.  **Kloniraj in Namesti:**
+    ```powershell
+    git clone https://github.com/SWivid/F5-TTS.git
+    cd F5-TTS
+    pip install -e .
+    ```
+
+## 3. Uporaba (Inference)
+
+Najlažji način je uporaba skripte `inference.py` iz terminala.
+
+1.  **Zaženi:**
+    ```powershell
+    python inference.py --model_path models/VibeVoice-1.5B
+    ```
+
+**Opomba:** Skripta `install_vibevoice_rtx.sh` samodejno popravi težavo z manjkajočo `generate.py` datoteko v modelu.
+
+## Reševanje Težav
+
+### "CUDA Out of Memory"
+Če imaš kartico z manj VRAM-a (npr. RTX 3060 12GB ali manj):
+- Poskusi generirati krajše stavke.
+- Preveri, če obstaja `fp16` (half precision) opcija pri nalaganju modela.
+
+### "Flash Attention not found"
+Če namestitev `flash-attn` spodleti (pogosto na Windowsih):
+- Preveri, da imaš nameščen **Visual Studio Build Tools 2022** (C++).
+- Alternativno uporabi pre-built wheels za tvojo verzijo Pythona in CUDA (išči "flash-attention windows wheels").
