# Whisper Medium EN Fine-Tuned for Air Traffic Control (ATC)
|
| 35 |
+
|
| 36 |
+
## Model Overview
|
| 37 |
+
|
| 38 |
+
This model is a fine-tuned version of OpenAI's Whisper Medium EN model, specifically trained on **Air Traffic Control (ATC)** communication datasets. The fine-tuning process significantly improves transcription accuracy on domain-specific aviation communications, reducing the **Word Error Rate (WER) by 84%**, compared to the original pretrained model. The model is particularly effective at handling accent variations and ambiguous phrasing often encountered in ATC communications.
|
| 39 |
+
|
| 40 |
+
- **Base Model**: OpenAI Whisper Medium EN
|
| 41 |
+
- **Fine-tuned Model WER**: 15.08%
|
| 42 |
+
- **Pretrained Model WER**: 94.59%
|
| 43 |
+
- **Relative Improvement**: 84.06%
|

## Model Description
|
| 50 |
+
|
| 51 |
+
Whisper Medium EN fine-tuned for ATC is optimized to handle short, distinct transmissions between pilots and air traffic controllers. It is fine-tuned using data from:
|
| 52 |
+
- **[ATCO2 corpus](https://huggingface.co/datasets/Jzuluaga/atco2_corpus_1h)** (1-hour test subset)
|
| 53 |
+
- **[UWB-ATCC corpus](https://huggingface.co/datasets/Jzuluaga/uwb_atcc)**
|
| 54 |
+
|
| 55 |
+
The fine-tuned model demonstrates enhanced performance in interpreting various accents, recognizing non-standard phraseology, and processing noisy or distorted communications. It is highly suitable for aviation-related transcription tasks.
|
| 56 |
+
|
| 57 |
+
## Intended Use
|
| 58 |
+
|
| 59 |
+
The fine-tuned Whisper model is designed for:
|
| 60 |
+
- **Transcribing aviation communication**: Providing accurate transcriptions for ATC communications, including accents and variations in English phrasing.
|
| 61 |
+
- **Air Traffic Control Systems**: Assisting in real-time transcription of pilot-ATC conversations, helping improve situational awareness.
|
| 62 |
+
- **Research and training**: Useful for researchers, developers, or aviation professionals studying ATC communication or developing new tools for aviation safety.
|
| 63 |
+
|
| 64 |
+
You can test the model online using the [ATC Transcription Assistant](https://huggingface.co/spaces/jacktol/ATC-Transcription-Assistant), which lets you upload audio files and generate transcriptions.
|
| 65 |
+
|
| 66 |
+
## Dataset
|
| 67 |
+
|
| 68 |
+
The dataset used for fine-tuning includes:
|
| 69 |
+
- **ATCO2**: An air traffic control dataset featuring real-world communications, including a freely available 1-hour test subset.
|
| 70 |
+
- **UWB-ATCC**: A manually transcribed ATC corpus containing thousands of hours of recordings, focusing on air traffic communications.
|
| 71 |
+
|
| 72 |
+
For more details on the dataset, refer to the **[ATC Dataset page](https://huggingface.co/datasets/jacktol/atc-dataset)**.
|
| 73 |
+
|
| 74 |
+
## Training Procedure
|
| 75 |
+
|
| 76 |
+
- **Hardware**: Fine-tuning was conducted on two A100 GPUs with 80GB memory.
|
| 77 |
+
- **Epochs**: 10
|
| 78 |
+
- **Learning Rate**: 1e-5
|
| 79 |
+
- **Batch Size**: 32 (effective batch size with gradient accumulation)
|
| 80 |
+
- **Augmentation**: Dynamic data augmentation techniques (Gaussian noise, pitch shifting, etc.) were applied during training.
|
| 81 |
+
- **Evaluation Metric**: Word Error Rate (WER)
|
| 82 |
+
|
| 83 |
+
## Limitations
|
| 84 |
+
|
| 85 |
+
While the fine-tuned model performs well in ATC-specific communications, it may not generalize as effectively to other domains of speech. Additionally, like most speech-to-text models, transcription accuracy can be affected by extremely poor-quality audio or heavily accented speech not encountered during training.
