Abstract: Recent work on self-supervised pre-training focus</b> on leveraging large-scale unlabeled speech data to build robust end-to-end (E2E)acoustic models (AM) that can be later fine-tuned on downstream tasks e.g., automatic speech recognition (ASR). Yet, few works investigated the impact on performance when the data properties substantially differ between the pre-training and fine-tuning phases, termed domain shift. We target this scenario by analyzing the robustness of Wav2Vec 2.0 and XLS-R models on downstream ASR for a completely unseen domain, air traffic control (ATC) communications. We benchmark these two models on several open-source and challenging ATC databases with signal-to-noise ratio between 5 and 20 dB. Relative word error rate (WER) reductions between 20% to 40% are obtained in comparison to hybrid-based ASR baselines by only fine-tuning E2E acoustic models with a smaller fraction of labeled data. We analyze WERs on the low-resource scenario and gender bias carried by one ATC dataset. |

|
## Usage |
|
|
|
You can use our Google Colab notebook to run and evaluate our model: https://github.com/idiap/w2v2-air-traffic/blob/master/src/eval_xlsr_atc_model.ipynb |
|
|
|
## Intended uses & limitations |
|
|
|
This model was fine-tuned on air traffic control data. We don't expect that it keeps the same performance on some others datasets, e.g., LibriSpeech or CommonVoice. |
|
|
|
|
|
## Training and evaluation data |
|
|
|
See Table 1 (page 3) in our paper: [How Does Pre-trained Wav2Vec 2.0 Perform on Domain Shifted ASR? An Extensive Benchmark on Air Traffic Control Communications](https://arxiv.org/abs/2203.16822). We described there the partitions of how to use our model. |
|
|
|
- We use the UWB-ATCC + ATCOSIM corpus to fine-tune this model. You can download the raw data here: |
|
- https://lindat.mff.cuni.cz/repository/xmlui/handle/11858/00-097C-0000-0001-CCA1-0 and, |
|
- https://www.spsc.tugraz.at/databases-and-tools/atcosim-air-traffic-control-simulation-speech-corpus.html |
|
- However, do not worry, we have prepared the database in `Datasets format`: |
|
- Here, [UWB-ATCC corpus on HuggingFace](https://huggingface.co/datasets/Jzuluaga/uwb_atcc). |
|
- Here: [ATCOSIM CORPUS on HuggingFace](https://huggingface.co/datasets/Jzuluaga/atcosim_corpus). |
|
- If you want to prepare a database in HuggingFace format, you can follow the data loader script in: [data_loader_atc.py](https://huggingface.co/datasets/Jzuluaga/uwb_atcc/blob/main/atc_data_loader.py). |
|
|
|
## Writing your own inference script |
|
|
|
If you use language model, you need to install the KenLM bindings with: |
|
|
|
```bash |
|
conda activate your_environment |
|
pip install https://github.com/kpu/kenlm/archive/master.zip |
|
``` |
|
|
|
The snippet of code: |
|
|
|
```python |
|
from datasets import load_dataset, load_metric, Audio |
|
import torch |
|
from transformers import AutoModelForCTC, Wav2Vec2Processor, Wav2Vec2ProcessorWithLM |
|
import torchaudio.functional as F |
|
|
|
USE_LM = False |
|
DATASET_ID = "Jzuluaga/uwb_atcc" |
|
MODEL_ID = "Jzuluaga/wav2vec2-xls-r-300m-en-atc-uwb-atcc-and-atcosim" |
|
|
|
# 1. Load the dataset |
|
# we only load the 'test' partition, however, if you want to load the 'train' partition, you can change it accordingly |
|
uwb_atcc_corpus_test = load_dataset(DATASET_ID, "test", split="test") |
|
|
|
# 2. Load the model |
|
model = AutoModelForCTC.from_pretrained(MODEL_ID) |
|
|
|
# 3. Load the processors, we offer support with LM, which should yield better resutls |
|
if USE_LM: |
|
processor = Wav2Vec2ProcessorWithLM.from_pretrained(MODEL_ID) |
|
else: |
|
processor = Wav2Vec2Processor.from_pretrained(MODEL_ID) |
|
# 4. Format the test sample |
|
sample = next(iter(uwb_atcc_corpus_test)) |
|
file_sampling_rate = sample['audio']['sampling_rate'] |
|
# resample if neccessary |
|
if file_sampling_rate != 16000: |
|
resampled_audio = F.resample(torch.tensor(sample["audio"]["array"]), file_sampling_rate, 16000).numpy() |
|
else: |
|
resampled_audio = torch.tensor(sample["audio"]["array"]).numpy() |
|
input_values = processor(resampled_audio, return_tensors="pt").input_values |
|
|
|
# 5. Run the forward pass in the model |
|
with torch.no_grad(): |
|
logits = model(input_values).logits |
|
|
|
# get the transcription with processor |
|
if USE_LM: |
|
transcription = processor.batch_decode(logits.numpy()).text |
|
else: |
|
pred_ids = torch.argmax(logits, dim=-1) |
|
transcription = processor.batch_decode(pred_ids) |
|
# print the output |
|
print(transcription) |
|
``` |
