# mHubert Basque Discrete Units (k=1000, L9)
|
| 6 |
+
|
| 7 |
+
## Model Summary
|
| 8 |
+
This repository provides a fine-tuned **mHubert** (Multilingual HuBERT) model specifically optimized for the **Basque language**. It is designed to transform raw audio signals into discrete unit sequences, which serve as a compact, symbolic representation of speech.
|
| 9 |
+
|
| 10 |
+
The model extracts high-level acoustic and phonetic features from the **9th transformer layer** (Layer 9). These features are then quantized using a KMeans model with **1000 clusters**. This representation is widely used in generative speech research, including unit-based Vocoders.
|
| 11 |
+
|
| 12 |
+
## Key Features
|
| 13 |
+
* **Base Model**: mHubert (Multilingual HuBERT) fine-tuned for Basque.
|
| 14 |
+
* **Quantization**: KMeans with $k=1000$ clusters.
|
| 15 |
+
* **Extraction Layer**: Layer 9 (L9).
|
| 16 |
+
* **Input**: 16 kHz Basque speech audio.
|
| 17 |
+
* **Output**: 1D sequence of discrete unit IDs (indices 0–999).
|
| 18 |
+
* **Primary Use Case**: Speech discretization for generative modeling and unit-based synthesis.

## How to Use
|
| 30 |
+
|
| 31 |
+
To extract discrete units from an audio file, you will need `transformers`, `torch`, `torchaudio`, and `joblib`.

### Installation
|
| 34 |
+
```bash
|
| 35 |
+
pip install torch torchaudio transformers joblib huggingface_hub
