# PASQA — Pitch-Accent-Focused Speech Quality Assessment Model

Pretrained checkpoint for **[PASQA](https://github.com/lycorp-jp/PASQA)**, an SSL-based MOS prediction model
that estimates the perceptual quality of synthesized Japanese speech with a focus on
**pitch-accent correctness**.

The model is developed by LY Corporation and released alongside our INTERSPEECH 2026 paper.

## Usage

Inference is done with the code in the [PASQA](https://github.com/lycorp-jp/PASQA) repository. See the repository for setup and usage instructions.
