+# wav2vec2-base-cs-en-50k
+This is a bilingual Wav2Vec 2.0 base model pre-trained from 100 thousand hours of speech (50 thousand hours of Czech and 50 thousand hours of English).
+It has been released along with a paper **A Comparative Analysis of Bilingual and Trilingual Wav2Vec Models for
+Automatic Speech Recognition in Multilingual Oral History Archives** accepted to INTERSPEECH2024 conference. 
+
+## Paper 
+The pre-print of our paper is available at http://arxiv.org/abs/2407.17160.

+## Usage
+This model does not have a tokenizer as it was pretrained on audio alone.
+In order to use this model for speech recognition, a tokenizer should be created 
+and the model should be [fine-tuned](https://huggingface.co/blog/fine-tune-wav2vec2-english) on labeled ASR data.
+
+Inputs must be 16kHz mono audio files.
+
+This model can be used e.g., to extract per-frame contextual embeddings from audio:
+```python
+from transformers import Wav2Vec2Model, Wav2Vec2FeatureExtractor
+import torchaudio
+
+feature_extractor = Wav2Vec2FeatureExtractor.from_pretrained("fav-kky/wav2vec2-base-cs-en-100k")
+model = Wav2Vec2Model.from_pretrained("fav-kky/wav2vec2-base-cs-en-100k")
+
+speech_array, sampling_rate = torchaudio.load("/path/to/audio/file.wav")
+inputs = feature_extractor(
+    speech_array, 
+    sampling_rate=16_000, 
+    return_tensors="pt"
+)["input_values"][0]
+
+output = model(inputs)
+embeddings = output.last_hidden_state.detach().numpy()[0]
+```
