Known Issues

ASR

RNNT WER calculation when fused batch size > 1 during validation / test step()

Previously, the RNNT metric was stateful while the CTC one was not (r1.22.0, r1.23.0)

Therefore this calculation in the RNNT joint for fused operation worked properly. However with the unification of metrics in r1.23.0, a bug was introduced where only the last sub-batch of metrics calculates the scores and does not accumulate. This is patched via #8587 and will be fixed in the next release.

Workaround: Explicitly disable fused batch size during inference using the following command

from omegaconf import open_dict
model = ...
decoding_cfg = model.cfg.decoding
with open_dict(decoding_cfg):
  decoding_cfg.fused_batch_size = -1
model.change_decoding_strategy(decoding_cfg)

Note: This bug does not affect scores calculated via model.transcribe() (since it does not calculate metrics during inference, just text), or using the transcribe_speech.py or speech_to_text_eval.py in examples/asr.

Two failing unit tests due to a change in expected results, caused by lhotse version update.
