Welcome to the world of Emotion2Vec+, a cutting-edge framework designed for emotion recognition in speech. Whether you’re a developer, researcher, or AI enthusiast, this guide will help you navigate through the setup, usage, and troubleshooting of this powerful model. Let’s dive right into it!

What is Emotion2Vec+

Emotion2Vec+ is a speech emotion recognition (SER) foundation model that leverages advanced data-driven methods to recognize emotions accurately, regardless of the language or recording conditions. Built on extensive pseudo-labeled data, this large model boasts an impressive size of around 300 million parameters. It is a robust solution capable of recognizing a range of emotions including angry, happy, sad, and more.

The underlying principle of Emotion2Vec+ can be likened to a talented musician who can play any song regardless of its genre. Just as the musician relies on their experiences and learned techniques to adapt to different styles, Emotion2Vec+ uses its vast training data to adapt and succeed in recognizing emotions across various contexts.

How to Install Emotion2Vec+

• Ensure you have Python installed.
• Open a terminal window.
• Run the following command to install the necessary packages:

pip install -U funasr modelscope

Using Emotion2Vec+

To utilize the Emotion2Vec+ model, you’ll follow different pathways based on your choice of framework: ModelScope or FunASR.

• Using ModelScope:

Use the code snippet below to run inference:

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

inference_pipeline = pipeline(
    task=Tasks.emotion_recognition,
    model='iicemotion2vec_plus_large'
)

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

• Using FunASR:

Use the following code to execute your model:

from funasr import AutoModel

model = AutoModel(model='iicemotion2vec_plus_large')
wav_file = 'example/test.wav'
res = model.generate(wav_file, output_dir='./outputs', granularity='utterance', extract_embedding=False)
print(res)

Troubleshooting

While using Emotion2Vec+, you might encounter some issues. Here are a few troubleshooting ideas:

• Issue: Model not downloading
  If you face difficulties downloading the model, verify your internet connection and ensure that you have permission to access external URLs.
• Issue: Errors in input format
  Ensure that your input audio files are in the correct format (WAV) and comply with the specified size limits (max 10M).
• Issue: Output files not generated
  Check that you have specified an existing output directory and that your model is correctly instantiated.
