| C<sup>2</sup>SER: [Paper](https://arxiv.org/abs/2502.18186) | [Code](https://github.com/zxzhao0/C2SER) | [HuggingFace](https://huggingface.co/collections/ASLP-lab/c2ser-67bc735d820403e7969fe8a0) |
|
|
| ## Introduction |
|
|
| This repository contains the implementation of Emotion2Vec-S, a self-supervised learning (SSL) model for speech emotion recognition, as presented in our paper "Steering Language Model to Stable Speech Emotion Recognition via Contextual Perception and Chain of Thought". |
|
|
| ## Requirements and Installation |
|
|
| This project follows the fairseq installation process. |
|
|
| ### Requirements |
|
|
| - PyTorch version >= 1.10.0 |
| - Python version >= 3.8 |
|
|
| ### Installation |
|
|
| To install fairseq and develop locally: |
|
|
| ```bash |
| git clone https://github.com/pytorch/fairseq |
| cd fairseq |
| pip install --editable ./ |
| ``` |
|
|
| ### Feature Extraction |
|
|
| You can download the pre-trained [Emotion2vec-S model](https://drive.google.com/drive/folders/1LWWi6bahzn7fJP4fCgPleOyQ30sD_BWO?usp=drive_link) and put it in the `./Emotion2Vec-S/ckpt` folder. |
| Meanwhile,we have provided the pretrained checkpoints in the huggingface model hub. You can also download ckpt file from [here](https://huggingface.co/ASLP-lab/Emotion2Vec-S). We also provide [here](https://drive.google.com/drive/folders/12AOVJT7I9GSLJnjHa-Elc-UKgog-mZR2) the feature files for the Emo-Emilia dataset extracted using Emotion2vec-S. |
|
|
| If you want to extract features using Emotion2Vec-S,you will also need to provide a `wav.scp` file and place it in the `./Emotion2Vec-S` directory. Here is an example of the `wav.scp` file:: |
| ```pgsql |
| audio_name1 /path/to/audio_name1.wav |
| audio_name2 /path/to/audio_name2.wav |
| audio_name3 /path/to/audio_name3.wav |
| ``` |
|
|
| Next, you can directly run the following code to extract features: |
| ```python |
| import torch |
| import os |
| import sys |
| import json |
| import numpy as np |
| import argparse |
| from tqdm import tqdm |
| import torchaudio |
| import torch.nn.functional as F |
| import fairseq |
| from dataclasses import dataclass |
| |
| SAMPLING_RATE=16000 |
| |
| @dataclass |
| class UserDirModule: |
| user_dir: str |
| |
| def extract_fairseq_feature(wav_path, model, device): |
| try: |
| wav, sr = torchaudio.load(wav_path) |
| # 合并多声道为单声道(取平均) |
| if wav.size(0) > 1: |
| wav = torch.mean(wav, dim=0, keepdim=True) |
| if sr != SAMPLING_RATE: |
| wav = torchaudio.functional.resample(wav, sr, SAMPLING_RATE) |
| wav = wav[0, :].view(1, -1) |
| wav = wav.to(device) |
| out = model.extract_features(wav) |
| return out |
| except Exception as e: |
| print(f"Error processing audio file {wav_path}: {e}") |
| return None |
| |
| if __name__ == '__main__': |
| |
| parser = argparse.ArgumentParser() |
| parser.add_argument('--model_path', type=str, default="./Emotion2Vec-S/ckpt/checkpoint.pt") |
| parser.add_argument('--model_dir', type=str, default="./Emotion2Vec-S/examples/data2vec/") |
| parser.add_argument('--dump_dir', type=str, default="./Emotion2Vec-S/features_frm") |
| parser.add_argument('--device', type=str, default='cuda') |
| parser.add_argument('--data', type=str, default="./Emotion2Vec-S/wav.scp") |
| parser.add_argument('--level', type=str, default="frame", help="frame or utterance") |
| args = parser.parse_args() |
| |
| data = {} |
| with open(args.data, 'r') as f: |
| for line in f: |
| seg_id, wav_path = line.strip().split(maxsplit=1) |
| data[seg_id] = wav_path |
| |
| os.makedirs(args.dump_dir, exist_ok=True) |
| |
| seg_ids = data.keys() |
| print(f'Loaded {len(seg_ids)} audio entries') |
| # load models |
| my_model_path = UserDirModule(args.model_dir) |
| fairseq.utils.import_user_module(my_model_path) |
| model, cfg, task = fairseq.checkpoint_utils.load_model_ensemble_and_task([args.model_path]) |
| model = model[0].to(args.device) |
| |
| for seg_id in tqdm(seg_ids): |
| |
| wav_path = data[seg_id] |
| if not os.path.exists(wav_path): |
| print(f"WARNING: {wav_path} does not exist") |
| continue |
| try: |
| torchaudio.load(wav_path) |
| except: |
| print(f'ERROR: Failed to load {wav_path}') |
| continue |
| |
| feat = extract_fairseq_feature(wav_path, model, args.device) |
| |
| if feat is not None: |
| if args.level == 'frame': |
| feat = feat['x'].cpu().detach().numpy()[0] |
| elif args.level == 'utterance': |
| feat = feat['utt_x'].cpu().detach().numpy()[0] |
| else: |
| raise ValueError("Unknown level: {}".format(args.level)) |
| |
| save_path = os.path.join(args.dump_dir, f"{seg_id}.npy") |
| os.makedirs(os.path.dirname(save_path), exist_ok=True) |
| np.save(save_path, feat) |
| print(f"Processed: {seg_id} | Shape: {feat.shape} | Saved to: {save_path}") |
| else: |
| print(f"Skipped problematic file: {seg_id}") |
| |
| ``` |
| Alternatively, you can adjust the code according to your needs. The code path is `./Emotion2Vec-S/speech_feature_extraction.py`. You can also use the `./Emotion2Vec-S/extract_feature.sh` script to batch process features for multiple datasets. The script supports parallel processing and offers the following parameters: |
|
|
| - `--model_path`: Path to the checkpoint file |
| - `--model_dir`: Path to the model |
| - `--dump_dir`: Directory to save extracted features |
| - `--device`: Device to run the model on (e.g., 'cuda:0') |
| - `--data`: Path to the dataset scp file |
| - `--level`: Level of feature (frame level or utterance level) |
|
|
| ## 2. Training and testing on EmoBox using extracted features |
|
|
| If you want to test our model on other datasets using [EmoBox](https://github.com/emo-box/EmoBox/tree/main). There is also an example provided below, which you can modify to suit your needs: |
|
|
| Use k-fold cross-validation with learning rates (1e-3, 1e-4) and hidden sizes (128, 256): |
|
|
| ```bash |
| cd examples/sb |
| data=/path/to/your/data_files |
| lrs=(1e-3 1e-4) # Learning rate list |
| hidden_sizes=(128 256) # Hidden size list |
| gpus=(0 1 2 3) # GPU list |
| task_id=0 |
| declare -A dataset_folds=( |
| ["mesd"]=1 |
| ) |
| declare -A dataset_classes=( |
| ["mesd"]=6 |
| ) |
| datasets=("mesd") |
| |
| for dataset in "${datasets[@]}"; do |
| folds=${dataset_folds[$dataset]} |
| n_classes=${dataset_classes[$dataset]} |
| |
| for lr in "${lrs[@]}"; do |
| for hidden_size in "${hidden_sizes[@]}"; do |
| gpu=${gpus[$task_id % ${#gpus[@]}]} |
| export CUDA_VISIBLE_DEVICES=$gpu |
| task_number=$((task_id + 1)) |
| for fold in $(seq 1 $folds); do |
| echo "Training fold $fold with lr=$lr, hidden_size=$hidden_size on GPU $gpu, task_number=$task_number, dataset=$dataset..." |
| python3 train.py \ |
| hparams/data2vec2-large_freeze.yaml \ |
| --output_folder /path/to/your/${dataset}-S/fold${fold}_lr${lr}_hidden${hidden_size} \ |
| --seed 1234 \ |
| --batch_size 32 \ |
| --lr $lr \ |
| --train_annotation ${data}/${dataset}/fold_${fold}/${dataset}_train_fold_${fold}.json \ |
| --test_annotation ${data}/${dataset}/fold_${fold}/${dataset}_test_fold_${fold}.json \ |
| --number_of_epochs 100 \ |
| --feat_dir /path/to/your/dump_${dataset}-S \ |
| --label_map ${data}/${dataset}/label_map.json \ |
| --device cuda \ |
| --out_n_neurons ${n_classes} \ |
| --hidden_size $hidden_size & |
| done |
| task_id=$((task_id + 1)) |
| done |
| done |
| done |
| |
| wait |
| echo "All training tasks completed." |
| ``` |
