+# Usage for inference
+
+In the following it is shown how the model can be used in inference on a sample of the [Common Voice dataset](https://commonvoice.mozilla.org/en/datasets)
+
+```python
+#!/usr/bin/env python3
+from transformers import Wav2Vec2Processor, Wav2Vec2ForCTC
+from datasets import load_dataset
+import torchaudio
+import torch
+
+# resample audio
+
+# load model & processor
+model = Wav2Vec2ForCTC.from_pretrained("facebook/wav2vec2-base-10k-voxpopuli-ft-hr")
+processor = Wav2Vec2Processor.from_pretrained("facebook/wav2vec2-base-10k-voxpopuli-ft-hr")
+
+# load dataset
+ds = load_dataset("common_voice", "hr", split="validation[:1%]")
+
+# common voice does not match target sampling rate
+common_voice_sample_rate = 48000
+target_sample_rate = 16000
+
+resampler = torchaudio.transforms.Resample(common_voice_sample_rate, target_sample_rate)
+
+
+# define mapping fn to read in sound file and resample
+def map_to_array(batch):
+    speech, _ = torchaudio.load(batch["path"])
+    speech = resampler(speech)
+    batch["speech"] = speech[0]
+    return batch
+
+
+# load all audio files
+ds = ds.map(map_to_array)
+
+# run inference on the first 5 data samples
+inputs = processor(ds[:5]["speech"], sampling_rate=target_sample_rate, return_tensors="pt", padding=True)
+
+# inference
+logits = model(**inputs).logits
+predicted_ids = torch.argmax(logits, axis=-1)
+
+print(processor.batch_decode(predicted_ids))
+```
