+# Magpie TTS C++ backend
+
+This backend runs NVIDIA's **Magpie TTS Multilingual 357M** GGUF through
+[magpie-tts.cpp](https://github.com/mudler/magpie-tts.cpp), a from-scratch
+C++/ggml port (model + NanoCodec + tokenizer + G2P dictionaries in one
+self-contained GGUF, no Python at inference time). It generates **22.05 kHz
+mono** speech in 5 baked voices across 9+ languages.
+
+The library is loaded via purego (cgo-less `dlopen`) exactly like
+`qwen3-tts-cpp` / `moss-tts-cpp`; the flat C-API (`magpie_tts_capi_*`) is
+exported directly by the upstream shared library, so there is no local C shim.
+
+## Model configuration
+
+The model path points at the single GGUF:
+
+```yaml
+name: magpie-tts-cpp
+backend: magpie-tts-cpp
+parameters:
+  model: magpie-tts-multilingual-357m-q8_0.gguf
+known_usecases:
+  - tts
+options:
+  - "speaker:Aria"   # optional default voice (Aria, Jason, John, Leo, Sofia, or 0-4)
+  - "language:en"    # optional default language
+```
+
+GGUFs live at
+[mudler/magpie-tts.cpp-gguf](https://huggingface.co/mudler/magpie-tts.cpp-gguf)
+(q8_0 recommended: near-lossless, ~624 MB, fastest decode).
+
+## Voices and languages
+
+Magpie has 5 baked speakers - `Aria`, `Jason`, `John`, `Leo`, `Sofia` - and no
+voice cloning. The request `voice` accepts the names case-insensitively or the
+indices `0`-`4`; empty selects Aria. Languages: `en`, `es`, `de`, `fr`, `it`,
+`pt-BR`, `hi`, `vi`, `ko`, `ar-AE`, `ar-SA`, `ar-MSA` (case-insensitive;
+default `en`).
+
+## API example
+
+```bash
+curl http://localhost:8080/v1/audio/speech \
+  -H 'Content-Type: application/json' \
+  -d '{
+    "model": "magpie-tts-cpp",
+    "input": "Hello world, this is a test of the text to speech system.",
+    "voice": "sofia",
+    "language": "en"
+  }' \
+  --output speech.wav
+```
+
+## Native end-to-end test
+
+The labeled test loads a real GGUF, synthesizes WAVs (verifying rate, layout
+and non-silence), and exercises the streaming path:
+
+```bash
+make -C backend/go/magpie-tts-cpp magpie-tts-cpp
+
+MAGPIETTS_MODEL=/path/to/magpie-tts-multilingual-357m-q8_0.gguf \
+MAGPIETTS_LIBRARY=backend/go/magpie-tts-cpp/libgomagpiettscpp-fallback.so \
+  go test ./backend/go/magpie-tts-cpp -ginkgo.label-filter=e2e
+```
+
+`bash test.sh` does the same and auto-downloads the q8_0 GGUF when
+`MAGPIETTS_MODEL` is unset.
