- class athena.data.datasets.kws.speech_wakeup_kaldiio_av.SpeechWakeupDatasetKaldiIOBuilderAVCE(config=None)¶
Bases:
athena.data.datasets.base.BaseDatasetBuilderDataset builder for RNN model. The builder mix the spliced frame in one dim For example (1, 1323) The input data format is (batch, t, dim, channel) For example (b, t, 1323, 1) The output data format is (batch, timestep)

- splice_feature(feature, input_left_context, input_right_context)¶
splice features according to input_left_context and input_right_context input_left_context: the left features to be spliced,
repeat the first frame in case out the range
- input_right_context: the right features to be spliced,
repeat the last frame in case out the range
- Parameters
feature – the input features, shape may be [timestamp, dim, 1]
- Returns
the spliced features
- Return type
