# Parakeet-TDT 0.6B HD Articulation

Official checkpoint for the paper **"Huntington Disease Automatic Speech Recognition with Biomarker Supervision."**

## Model description

This model is an articulation-aware variant of **Parakeet-TDT 0.6B HD**, tuned for automatic speech recognition on speech affected by **Huntington disease (HD)**. It extends the HD-adapted base model with auxiliary supervision from articulatory biomarker labels.

## What this model does

The model transcribes English read / controlled clinical speech from speakers with Huntington disease and healthy controls. It is intended as a research model for studying robust ASR under hyperkinetic motor-speech disruption and for analyzing the effect of articulatory supervision on transcription behavior.

## Training

The model was initialized from `charleslwang/parakeet-tdt-0.6b-HD` and further adapted using **parameter-efficient encoder-side adapters** with an auxiliary objective based on articulatory biomarker labels, while keeping the pretrained backbone frozen.

## Evaluation

On the reported HD test set, this model achieved:

- **WER:** 6.44
- **Substitutions:** 1.94
- **Deletions:** 3.21
- **Insertions:** 1.29

## Intended use

This model is intended for:

- research on pathological / atypical speech recognition,
- benchmarking ASR on Huntington disease speech,
- studying how articulatory auxiliary supervision reshapes error behavior.

It is **not** intended for clinical diagnosis, treatment decisions, or standalone medical use.

## Limitations

- Trained and evaluated on a relatively small, high-fidelity clinical corpus.
- Primarily reflects controlled / read speech rather than spontaneous conversational speech.
- Did not outperform the plain HD-adapted model on overall WER.
- May not generalize to severe out-of-distribution impairment, other languages, or other recording conditions.
