Description
Pretrained Wav2vec2 model, adapted from Hugging Face and curated to provide scalability and production-readiness using Spark NLP.asr_wav2vec2_large_xlsr_bemba is a Bemba (Zambia) model originally trained by csikasote.
NOTE: This model only works on a CPU, if you need to use this model on a GPU device please use asr_wav2vec2_large_xlsr_bemba_gpu
How to use
