🚀 Emotion Diarization with WavLM Large on 5 popular emotional datasets
This repository offers all the essential tools for speech emotion diarization. It utilizes a fine - tuned wavlm (large) model through SpeechBrain. The model is trained on concatenated audios and tested on ZaionEmotionDataset. The evaluation metric is Emotion Diarization Error Rate (EDER). For more details, refer to the paper link.
🚀 Quick Start
For a better experience, we recommend you to learn more about SpeechBrain. The model performance on ZED (test set) is as follows:
Release |
EDER(%) |
05 - 07 - 23 |
29.7 (Avg: 30.2) |
✨ Features
This system consists of a wavlm encoder and a downstream frame - wise classifier. The goal of the task is to predict the correct emotion components and their boundaries within a speech recording. Currently, the model is trained with audios that contain only 1 non - neutral emotion event. The system is trained with recordings sampled at 16kHz (single channel). The code will automatically normalize your audio (i.e., resampling + mono channel selection) when calling diarize_file if necessary.
📦 Installation
First, install the development version of SpeechBrain using the following commands:
git clone https://github.com/speechbrain/speechbrain.git
cd speechbrain
pip install -r requirements.txt
pip install --editable .
Please note that we encourage you to read our tutorials and learn more about SpeechBrain.
💻 Usage Examples
Basic Usage
from speechbrain.inference.diarization import Speech_Emotion_Diarization
classifier = Speech_Emotion_Diarization.from_hparams(
source="speechbrain/emotion-diarization-wavlm-large"
)
diary = classifier.diarize_file("speechbrain/emotion-diarization-wavlm-large/example.wav")
print(diary)
diary = classifier.diarize_file("speechbrain/emotion-diarization-wavlm-large/example_sad.wav")
print(diary)
The output will be a dictionary containing emotion components and their boundaries.
Advanced Usage
To perform inference on the GPU, add run_opts={"device":"cuda"}
when calling the from_hparams
method.
Training
The model was trained with SpeechBrain (aa018540). To train it from scratch, follow these steps:
- Clone SpeechBrain:
git clone https://github.com/speechbrain/speechbrain/
- Install it:
cd speechbrain
pip install -r requirements.txt
pip install -e .
- Run Training:
cd recipes/ZaionEmotionDataset/emotion_diarization
python train.py hparams/train.yaml --zed_folder /path/to/ZED --emovdb_folder /path/to/EmoV-DB --esd_folder /path/to/ESD --iemocap_folder /path/to/IEMOCAP --jlcorpus_folder /path/to/JL_corpus --ravdess_folder /path/to/RAVDESS
