+## Output
+As this model is specifically trained for a speech-to-phoneme task, the output is sequence of [IPA-encoded](https://en.wikipedia.org/wiki/International_Phonetic_Alphabet) words, without punctuation.
+If you don't read the phonetic alphabet fluently, you can use this excellent [IPA reader website](http://ipa-reader.xyz) to convert the transcript back to audio synthetic speech in order to check the quality of the phonetic transcription.
+## Link to other phonemizer models trained on other body conducted sensors :
+An entry point to all **phonemizers** (speech-to-phoneme ASR) models trained on different sensor data from the trained on different sensor data from the [Vibravox dataset](https://huggingface.co/datasets/Cnam-LMSSC/vibravox) is available at [https://huggingface.co/Cnam-LMSSC/vibravox_phonemizers](https://huggingface.co/Cnam-LMSSC/vibravox_phonemizers).
+### Disclaimer
+Each of these models has been trained for a **specific non-conventional speech sensor** and is intended to be used with **in-domain data**. The only exception is the headset microphone phonemizer, which can certainly be used for many applications using audio data captured by airborne microphones.
+Please be advised that using these models outside their intended sensor data may result in suboptimal performance.
+## Training procedure
+The model has been finetuned for 10 epochs with a constant learning rate of *1e-5*. To reproduce experiment please visit [jhauret/vibravox](https://github.com/jhauret/vibravox).
+## Inference script :
+```python
+import torch, torchaudio
+from transformers import AutoProcessor, AutoModelForCTC
+from datasets import load_dataset
+processor = AutoProcessor.from_pretrained("Cnam-LMSSC/phonemizer_forehead_accelerometer")
+model = AutoModelForCTC.from_pretrained("Cnam-LMSSC/phonemizer_forehead_accelerometer")
+test_dataset = load_dataset("Cnam-LMSSC/vibravox", "speech_clean", split="test", streaming=True)
+audio_48kHz = torch.Tensor(next(iter(test_dataset))["audio.forehead_accelerometer"]["array"])
+audio_16kHz = torchaudio.functional.resample(audio_48kHz, orig_freq=48_000, new_freq=16_000)
+inputs = processor(audio_16kHz, sampling_rate=16_000, return_tensors="pt")
+logits = model(inputs.input_values).logits
+predicted_ids = torch.argmax(logits,dim = -1)
+transcription = processor.batch_decode(predicted_ids)
+print("Phonetic transcription : ", transcription)
