# Parakeet TDT v3 — CoreML INT8 (iOS, 5s)

CoreML INT8 conversion of [NVIDIA Parakeet-TDT 0.6B v2](https://huggingface.co/nvidia/parakeet-tdt-0.6b-v2) for iOS, with encoder shape optimized for audio segments up to 5 seconds. Smaller and faster than the variable-length variant for short-form audio.

## Models

| Model | Description | Compute | Quantization |
|-------|-------------|---------|-------------|
| `encoder.mlmodelc` | FastConformer encoder (5s max) | Neural Engine | INT8 palettized |
| `decoder.mlmodelc` | LSTM prediction network | Neural Engine | FP16 |

## Usage

Used by [speech-swift](https://github.com/soniqo/speech-swift) `ParakeetASR` module:

```swift
let model = try await ParakeetASRModel.fromPretrained()
let text = try model.transcribeAudio(samples, sampleRate: 16000)
```
