OmniASR-CTC-300M-v2 GGUF

GGUF quantizations of OmniASR-CTC-300M-v2, a multilingual CTC-based Automatic Speech Recognition (ASR) model supporting over 1,600 languages.

This repository provides pre-quantized GGUF variants for efficient CPU and edge deployment with CrispASR and other GGUF-compatible runtimes.

Original Model

For Hugging Face Transformers format and usage, see the original model repository:
