class espnet3.components.abs_metric.AbsMetrics

Bases: ABC

Abstract base class for metrics used in inference evaluation.

Subclasses must implement __call__ to compute metric values from decoded hypotheses and references.

Example

>>> class DummyMetric(AbsMetrics):
...     def __call__(self, data, test_name, decode_dir):
...         return {"acc": 1.0}
