Description
Pretrained Wav2vec2 model, adapted from Hugging Face and curated to provide scalability and production-readiness using Spark NLP.asr_wav2vec2_large_xlsr_cantonese_by_ctl is a Yue Chinese model originally trained by ctl.
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_cantonese_by_ctl_gpu
How to use

.setInputCols("audio_assembler") \
.setOutputCol("text")
pipeline = Pipeline(stages=[
audio_assembler,
