HuBERT fine-tuned on DUSHA dataset for speech emotion recognition in russian language
The pre-trained model is this one - facebook/hubert-large-ls960-ft
The DUSHA dataset used can be found here
Fine-tuning
Fine-tuned in Google Colab using Pro account with A100 GPU
Freezed all layers exept projector, classifier and all 24 HubertEncoderLayerStableLayerNorm layers
Used half of the train dataset
Training parameters
- 2 epochs
- train batch size = 8
- eval batch size = 8
- gradient accumulation steps = 4
- learning rate = 5e-5 without warm up and decay
Metrics
Achieved
- accuracy = 0.86
- balanced = 0.76
- macro f1 score = 0.81 on test set, improving accucary and f1 score compared to dataset baseline

import torchaudio
import torch
feature_extractor = Wav2Vec2FeatureExtractor.from_pretrained("facebook/hubert-large-ls960-ft")
model = HubertForSequenceClassification.from_pretrained("xbgoose/hubert-speech-emotion-recognition-russian-dusha-finetuned")
num2emotion = {0: 'neutral', 1: 'angry', 2: 'positive', 3: 'sad', 4: 'other'}
filepath = "path/to/audio.wav"
waveform, sample_rate = torchaudio.load(filepath, normalize=True)
