# SSM-AST: State Space Models for Automatic Speech Transcription

This repository contains model artifacts for the master's thesis **“State Space Models for Automatic Speech Transcription.”** It provides the trained acoustic encoder checkpoints, language-model checkpoints, n-gram training text, and selected training logs used to support evaluation of a pure State Space Model (SSM) automatic speech transcription pipeline on LibriSpeech.

The code for training and evaluation is maintained separately. This Hugging Face repository is intended as a checkpoint and artifact archive so that the thesis evaluation pipeline can be run without retraining the full models from scratch.
