Whisper Large V3 Msp Podcast Emotion

🚀 Whisper-Large V3 for Categorical Emotion Classification

This model is designed for categorical emotion classification, leveraging the power of Whisper-Large V3 to accurately identify emotions in speech.

🚀 Quick Start

Download repo

git clone git@github.com:tiantiaf0627/vox-profile-release.git

Install the package

conda create -n vox_profile python=3.8
cd vox-profile-release
pip install -e .

Load the model

# Load libraries
import torch
import torch.nn.functional as F
from src.model.emotion.whisper_emotion import WhisperWrapper
# Find device
device = torch.device("cuda") if torch.cuda.is_available() else "cpu"
# Load model from Huggingface
model = WhisperWrapper.from_pretrained("tiantiaf/whisper-large-v3-msp-podcast-emotion").to(device)
model.eval()

Prediction

# Label List
emotion_label_list = [
    'Anger', 
    'Contempt', 
    'Disgust', 
    'Fear', 
    'Happiness', 
    'Neutral', 
    'Sadness', 
    'Surprise', 
    'Other'
]
    
# Load data, here just zeros as the example
# Our training data filters output audio shorter than 3 seconds (unreliable predictions) and longer than 15 seconds (computation limitation)
# So you need to prepare your audio to a maximum of 15 seconds, 16kHz and mono channel
max_audio_length = 15 * 16000
data = torch.zeros([1, 16000]).float().to(device)[:, :max_audio_length]
logits, embedding, _, _, _, _ = model(
    data, return_feature=True
)
    
# Probability and output
emotion_prob = F.softmax(logits, dim=1)
print(emotion_label_list[torch.argmax(emotion_prob).detach().cpu().item()])

✨ Features

• Emotion Classification: This model can classify categorical emotions from speech, including Anger, Contempt, Disgust, Fear, Happiness, Neutral, Sadness, Surprise, and Other.
• Based on Whisper-Large V3: Leveraging the powerful base model openai/whisper-large-v3 for high-performance emotion classification.
• Trained on MSP-Podcast Data: The model is trained using MSP-Podcast data, which might make it sensitive to content information for better emotion prediction from online content.

📚 Documentation

Model Description

This model includes the implementation of categorical emotion classification described in Vox-Profile: A Speech Foundation Model Benchmark for Characterizing Diverse Speaker and Speech Traits.

The training pipeline used is also the top-performing solution (SAILER) in INTERSPEECH 2025—Speech Emotion Challenge. Note that we did not use all the augmentation and did not use the transcript compared to our official challenge submission system, but we created a speech-only system to make the model simple but still effective.

We use the MSP-Podcast data to train this model, noting that the model might be sensitive to content information when making emotion predictions. However, this could be a good feature for classifying emotions from online content.

The included emotions are:

[
    'Anger', 
    'Contempt', 
    'Disgust', 
    'Fear', 
    'Happiness', 
    'Neutral', 
    'Sadness', 
    'Surprise', 
    'Other'
]
