Extern Sprint Dataset¶
This is a Dataset which you can use directly in RETURNN. You can use it to get any type of data from Sprint (RWTH ASR toolkit), e.g. you can use Sprint to do feature extraction and preprocessing.
This class is like SprintDatasetBase, except that we will start an external Sprint instance ourselves which will forward the data to us over a pipe. The Sprint subprocess will use SprintExternInterface to communicate with us.
