stt-hy-fastconformer-hybrid-ctc-large-GGUF

GGUF conversions of the CTC branch of nvidia/stt_hy_fastconformer_hybrid_large_pc for CrispASR. The upstream model is a hybrid transducer+CTC Armenian ASR release; the shared FastConformer encoder plus the auxiliary CTC head are extracted here as a standalone CTC model (the RNNT prediction network and joint are dropped), giving a compact Armenian ASR and forced-alignment model with punctuation + capitalisation.

QuantSizeDescription
F16219 MBFull precision
Q8_0130 MB8-bit
Q4_K82 MB4-bit K-quant (recommended)

Architecture

17-layer NeMo FastConformer encoder + Conv1d CTC head. d_model=512, 8 heads, SentencePiece vocab, 80 log-mel features, ~115M params.

Usage

# Armenian ASR:
crispasr --backend fastconformer-ctc -m stt-hy-fastconformer-hybrid-ctc-large-q4_k.gguf -f audio.wav

# Forced alignment (word timestamps for known text, or re-timing an .srt):
crispasr --align-only -am stt-hy-fastconformer-hybrid-ctc-large-q4_k.gguf \
    -f audio.wav --text-file subtitles.srt --align-output retimed.srt

All credit for the model goes to NVIDIA's NeMo team; this repository only repackages the CTC branch in GGUF form under the same CC-BY-4.0 license. Conversion: models/convert-stt-fastconformer-ctc-to-gguf.py in CrispASR.

Provenance and EU AI Act Art. 53 note

  • Upstream model: nvidia/stt_hy_fastconformer_hybrid_large_pc — published by nvidia.
  • Upstream licence: cc-by-4.0. This repository redistributes under the same terms; it grants no rights the upstream licence does not.
  • What was done here: format conversion and/or quantisation only (GGUF). No training, no fine-tuning, no merging, no distillation, no change to architecture, vocabulary or capability. Only the numeric representation of the upstream weights differs.
  • Training data: documented — where it is documented at all — by the upstream provider; see the upstream model card. No training data was used, added or selected by this repository.
  • Provider status: under Regulation (EU) 2024/1689 the upstream authors remain the provider of this model. Converting the serialisation format does not make this repository the provider of a new general-purpose AI model, and no such claim is made. Questions about training content, copyright policy or model capability belong upstream.
