 This model was trained using the NeMo toolkit [3], following the strategies below:
 
-- Initialized from a wav2vec SSL checkpoint pretrained on the LibriLight dataset[7].  
-- Trained for 150,000 steps on 128 A100 GPUs. 
+- Initialized from a FastConformer SSL checkpoint that was pretrained with a wav2vev method on the LibriLight dataset[7].  
+- Trained for 150,000 steps on 64 A100 GPUs. 
 - Dataset corpora were balanced using a temperature sampling value of 0.5.  
 - Stage 2 fine-tuning was performed for 2,500 steps on 4 A100 GPUs using approximately 500 hours of high-quality, human-transcribed data of NeMo ASR Set 3.0.
