This model is part of our ICASSP 2026 paper: Test-Time Adaptation Methods for Speech Emotion Recognition.

Model Description

Wav2Vec2 fine-tuned on RAVDESS for Task1 (intra-corpus personalization)

• Base Model: facebook/wav2vec2-base
• Dataset: RAVDESS
• Task: Task1 - intra-corpus personalization
• Emotions: neutral, calm, happy, sad, angry, fearful, disgust, surprised
• Number of Classes: 8

Usage

from transformers import AutoModelForAudioClassification, AutoFeatureExtractor
import torch
import torchaudio

# Load model and processor
model_checkpoint = "LincolnD/wav2vec2-base-finetuned-ravdess-personalization"
processor = AutoFeatureExtractor.from_pretrained(model_checkpoint)
model = AutoModelForAudioClassification.from_pretrained(model_checkpoint)

# Load and process audio
audio_path = "path/to/your/audio.wav"
waveform, sample_rate = torchaudio.load(audio_path)

# Resample to 16kHz if needed
if sample_rate != 16000:
    resampler = torchaudio.transforms.Resample(sample_rate, 16000)
    waveform = resampler(waveform)

# Process and predict
inputs = processor(waveform.squeeze().numpy(), sampling_rate=16000, return_tensors="pt", padding=True)
with torch.no_grad():
    outputs = model(**inputs)
    predictions = torch.argmax(outputs.logits, dim=-1)

emotion_id = predictions.item()
emotion = model.config.id2label[emotion_id]
print(f"Predicted emotion: {emotion}")

Training Details

This model was fine-tuned from the pre-trained Wav2Vec2 base model on the RAVDESS dataset.

Training Data
