class espnet3.systems.asr.system.ASRSystem(training_config=None, inference_config=None, metrics_config=None, **kwargs)

Bases: BaseSystem

ASR-specific system.

This system adds. : - Tokenizer training inside train()

Additional stage log paths. : - train_tokenizer -> training_config.tokenizer.save_path

Initialize the ASR system with ASR-specific stage mappings.

pack_model(*args, **kwargs)

Pack model artifacts into an espnet3 bundle.

train(*args, **kwargs)

Train the model, training the tokenizer first if needed.

This stage checks for a cached tokenizer model and runs tokenizer training before delegating to the base training routine.

• Raises:RuntimeError – If neither dataset references nor dataset_dir exist.

train_tokenizer(*args, **kwargs)

Train a SentencePiece tokenizer based on configured text.

The text builder configured in training_config.tokenizer.text_builder is used to generate training text, which is then saved and consumed by the SentencePiece trainer.

• Raises:RuntimeError – If required tokenizer config is missing or invalid.
