Command Recognition with ECAPA embeddings on UrbanSoudnd8k

This repository provides all the necessary tools to perform sound recognition with SpeechBrain using a model pretrained on UrbanSound8k. You can download the dataset here The provided system can recognize the following 10 keywords:

dog_bark, children_playing, air_conditioner, street_music, gun_shot, siren, engine_idling, jackhammer, drilling, car_horn

For a better experience, we encourage you to learn more about SpeechBrain. The given model performance on the test set is:

Release Accuracy 1-fold (%)

Pipeline description

This system is composed of a ECAPA model coupled with statistical pooling. A classifier, trained with Categorical Cross-Entropy Loss, is applied on top of that.

Install SpeechBrain

First of all, please install SpeechBrain with the following command:

pip install speechbrain

Please notice that we encourage you to read our tutorials and learn more about SpeechBrain.

Perform Sound Recognition

import torchaudio
from speechbrain.pretrained import EncoderClassifier
classifier = EncoderClassifier.from_hparams(source="speechbrain/urbansound8k_ecapa", savedir="pretrained_models/gurbansound8k_ecapa")
out_prob, score, index, text_lab = classifier.classify_file('speechbrain/urbansound8k_ecapa/dog_bark.wav')
print(text_lab)

Inference on GPU

To perform inference on the GPU, add run_opts={"device":"cuda"} when calling the from_hparams method.

Training

The model was trained with SpeechBrain (8cab8b0c). To train it from scratch follows these steps:

  1. Clone SpeechBrain:

    git clone https://github.com/speechbrain/speechbrain/
  2. Install it:

    cd speechbrain
    pip install -r requirements.txt
    pip install -e .
  3. Run Training:

    cd recipes/UrbanSound8k/SoundClassification
    python train.py hparams/train_ecapa_tdnn.yaml --data_folder=your_data_folder

You can find our training results (models, logs, etc) here.
