EMOTION2VEC+

emotion2vec+: speech emotion recognition foundation model
emotion2vec+ base model

Guides

emotion2vec+ is a series of foundational models for speech emotion recognition (SER). We aim to train a "whisper" in the field of speech emotion recognition, overcoming the effects of language and recording environments through data-driven methods to achieve universal, robust emotion recognition capabilities. The performance of emotion2vec+ significantly exceeds other highly downloaded open-source models on Hugging Face.

This version (emotion2vec_plus_base) uses a large-scale pseudo-labeled data for finetuning to obtain a base size model (~90M), and currently supports the following categories: 0: angry 1: disgusted 2: fearful 3: happy 4: neutral 5: other 6: sad 7: surprised 8: unknown

Data Iteration

We offer 3 versions of emotion2vec+, each derived from the data of its predecessor. If you need a model focusing on spech emotion representation, refer to emotion2vec: universal speech emotion representation model.

  • emotion2vec+ seed: Fine-tuned with academic speech emotion data from EmoBox
  • emotion2vec+ base: Fine-tuned with filtered large-scale pseudo-labeled data to obtain the base size model (~90M)
  • emotion2vec+ large: Fine-tuned with filtered large-scale pseudo-labeled data to obtain the large size model (~300M)

The iteration process is illustrated below, culminating in the training of the emotion2vec+ large model with 40k out of 160k hours of speech emotion data. Details of data engineering will be announced later.

Installation

pip install -U funasr modelscope

Usage

input: 16k Hz speech recording

granularity:

  • "utterance": Extract features from the entire utterance
  • "frame": Extract frame-level features (50 Hz)

extract_embedding: Whether to extract features; set to False if using only the classification model

Inference based on ModelScope 

from modelscope.pipelines import pipeline
from modelscope.utils.constant import Tasks

inference_pipeline = pipeline(
    task=Tasks.emotion_recognition,
    model="iic/emotion2vec_plus_base")

rec_result = inference_pipeline('https://isv-data.oss-cn-hangzhou.aliyuncs.com/ics/MaaS/ASR/test_audio/asr_example_zh.wav', granularity="utterance", extract_embedding=False)
print(rec_result)

Inference based on FunASR 

from funasr import AutoModel

model = AutoModel(model="iic/emotion2vec_plus_base")

wav_file = f"{model.model_path}/example/test.wav"
res = model.generate(wav_file, output_dir="./outputs", granularity="utterance", extract_embedding=False)
print(res)

Note: The model will automatically download.

Supports input file list, wav.scp (Kaldi style):

wav_name1 wav_path1.wav
wav_name2 wav_path2.wav
...

Outputs are emotion representation, saved in the output_dir in numpy format (can be loaded with np.load())

Note

This repository is the Huggingface version of emotion2vec, with identical model parameters as the original model and Model Scope version.
