 ## Usage in `transformers`
 
-So far untested approach that worked before:
+Tested with `transformers==4.18.0`, `torch==1.11.0`, and `SoundFile==0.10.3.post1`.
+
 
 ```python
-from transformers import Wav2Vec2Processor, Wav2Vec2ForCTC
+from transformers import Wav2Vec2ProcessorWithLM, Wav2Vec2ForCTC
 import soundfile as sf
 import torch
 import os
-
 device = torch.device("cuda:0" if torch.cuda.is_available() else "cpu")
-
 # load model and tokenizer
-processor = Wav2Vec2Processor.from_pretrained(
+processor = Wav2Vec2ProcessorWithLM.from_pretrained(
     "5roop/wav2vec2-xls-r-parlaspeech-hr-lm")
 model = Wav2Vec2ForCTC.from_pretrained("5roop/wav2vec2-xls-r-parlaspeech-hr-lm")
-
-
 # download the example wav files:
-os.system("wget https://huggingface.co/5roop/wav2vec2-xls-r-parlaspeech-hr-lm/raw/main/00020570a.flac.wav")
-
+os.system("wget https://huggingface.co/classla/wav2vec2-large-slavic-parlaspeech-hr/raw/main/00020570a.flac.wav")
 # read the wav file 
 speech, sample_rate = sf.read("00020570a.flac.wav")
-input_values = processor(speech, sampling_rate=sample_rate, return_tensors="pt").input_values.to(device)
+input_values = processor(speech, sampling_rate=sample_rate, return_tensors="pt").input_values.cuda()
+inputs = processor(speech, sampling_rate=sample_rate, return_tensors="pt")
+with torch.no_grad():
+    logits = model(**inputs).logits
+transcription = processor.batch_decode(logits.numpy()).text[0]
 
 # remove the raw wav file
 os.system("rm 00020570a.flac.wav")
+transcription
 
-# retrieve logits
-logits = model.to(device)(input_values).logits
-
-# take argmax and decode
-predicted_ids = torch.argmax(logits, dim=-1)
-transcription = processor.decode(predicted_ids[0]).lower()
-
-# transcription: 'veliki broj poslovnih subjekata posluje sa minusom velik dio'
+# transcription: 'velik broj poslovnih subjekata posluje sa minusom velik dio'
