+# MMS-LID 256 (ONNX)
+
+ONNX export of **MMS-LID** (Massively Multilingual Speech - Language Identification) for **256 languages**. For on-device or server inference without PyTorch.
+
+- **Base model:** [facebook/mms-lid-256](https://huggingface.co/facebook/mms-lid-256)
+- **Format:** ONNX
+- **Languages:** 256 (ISO 639-3)
+
+## Contents
+
+- ONNX model file(s) for the Wav2Vec2-based LID classifier
+- Label mapping (e.g. `labels.json` or `mms_lid_id2label.json`) for index to language code
+
+## Input / Output
+
+- **Input:** Raw waveform, 16 kHz mono, 10 seconds (160,000 samples)
+- **Output:** Logits over 256 language classes; `argmax` gives the predicted language index. Map index to ISO 639-3 code using the included labels file.
+
+## Usage
+
+1. Load the ONNX model with your runtime (e.g. ONNX Runtime, or convert further to Core ML for iOS).
+2. Feed 10 seconds of 16 kHz mono float32 audio.
+3. Take `argmax` of the logits output and look up the language code in the labels file.
