# Wav2Vec2-LV-60-Espeak-CV-FT (ONNX)
|
| 16 |
+
|
| 17 |
+
This is an **ONNX export** of the [facebook/wav2vec2-lv-60-espeak-cv-ft](https://huggingface.co/facebook/wav2vec2-lv-60-espeak-cv-ft) model.
|
| 18 |
+
|
| 19 |
+
It is designed for client-side inference in the **Music Video Maker** application to perform forced alignment of lyrics to audio.
|
| 20 |
+
|
| 21 |
+
## Model Details

|
| 24 |
+
- **Format**: ONNX (Open Neural Network Exchange)
|
| 25 |
+
- **Precision**: FP16 (Float16)
|
| 26 |
+
- **Output**: IPA Phoneme logits (392 vocab size)
|
| 27 |
+
- **Sample Rate**: 16kHz
|
| 28 |
+
|
| 29 |
+
## Usage
|
| 30 |

|
| 36 |
+
- **Type**: Float32 tensor
|
| 37 |
+
|
| 38 |
+
### Output
|
| 39 |
+
- **Name**: `logits`
|
| 40 |
+
- **Shape**: `[batch_size, frames, 392]` (392 is the vocab size)
