NOTE:

• you may need additional setting for phonemizer if you want to do phoneme-related data preprocessing

0. Data Preparation For SLURP, The preprocessed dataset is datasets/slurp/slurp_with_oracle_test.json. The preprocessed dataset without filtering and separating test sets is datasets/slurp/slurp.json The data preprocessing includes multiple operations including:
   • Derive ASR hypothesis
   • Generate phoneme sequences by phonemizer
   • Preprocess the dataset (1st version)
     • Scripts in prepare_data would you understand the process:
     • first run make_golden_dataset read only from data provided in SLURP repo
     • and then make_dataset would need transcriptions from different systems
   • Fine-tune roberta-base models on the 1st version dataset
   • Collect predictions and sub-sample the dataset with agreed pseudo label

For ATIS/TREC6 from PhonemeBERT, You can just clone their repo and unzip the dataset.

1. Contrastive Pretraining

python contrastive_pretraining.py

2. Fine-tuning

python finetune_on_slurp.py

or on the phonemebert datasets:

python finetune_on_phonemebert.py

Training and evaluation are both included in these two scripts. Adjust the arguments as you need.
