haerik/seoul_corpus_asr_xeus
ESPnet2 ASR model for the Seoul Corpus, a Korean corpus of spontaneous
interview speech (40 speakers, 1 hour each). Trained with the
egs2/seoul_corpus/asr1 recipe.
The model transcribes speech and the corpus's non-speech annotations:
<SIL>, <NOISE>, <VOCNOISE>, <LAUGH>, <UNKNOWN> and <PRIVATE.INFO>
are targets, not discarded labels.
Architecture
XEUS, a multilingual ESPnet SSL model is used as a frozen SSL frontend, with a trainable
E-Branchformer encoder and Transformer decoder on top (hybrid CTC/attention,
ctc_weight 0.5).
| total parameters | 621.43 M |
| trainable | 47.30 M (7.6%) |
| training data | 7238 utterances, 26.30 h |
| epochs | 40 |
Results
Test set: all 1409 annotated utterances. CER and WER are scored with the
special tags removed (--nlsyms_txt), so they measure transcription rather
than tag spelling; TER keeps them.
| CER | WER | TER |
|---|---|---|
| 12.4 | 34.0 | 21.5 |
No language model: decoding is attention + CTC only (lm_weight 0.0).
Usage
from espnet2.bin.asr_inference import Speech2Text
speech2text = Speech2Text.from_pretrained("haerik/seoul_corpus_asr_xeus")
text, *_ = speech2text(speech)[0]
