模型:
superb/hubert-large-superb-er
这是一个转移版本的 S3PRL's Hubert for the SUPERB Emotion Recognition task 。
基本模型是 hubert-large-ll60k ,其在16kHz采样的语音音频上进行了预训练。使用模型时,请确保您的语音输入也在16Khz采样。
有关更多信息,请参考 SUPERB: Speech processing Universal PERformance Benchmark 。
情感识别(ER)为每个话语预测一个情感类别。采用最常用的ER数据集 IEMOCAP ,并遵循传统的评估协议:我们将不平衡的情感类别剔除,以保留最终的四个类别,其中数据点数量相似,并在标准分割的五个折交叉验证。
有关原始模型的训练和评估说明,请参考 S3PRL downstream task README 。
您可以通过音频分类流程使用该模型:
from datasets import load_dataset from transformers import pipeline dataset = load_dataset("anton-l/superb_demo", "er", split="session1") classifier = pipeline("audio-classification", model="superb/hubert-large-superb-er") labels = classifier(dataset[0]["file"], top_k=5)
或直接使用该模型:
import torch import librosa from datasets import load_dataset from transformers import HubertForSequenceClassification, Wav2Vec2FeatureExtractor def map_to_array(example): speech, _ = librosa.load(example["file"], sr=16000, mono=True) example["speech"] = speech return example # load a demo dataset and read audio files dataset = load_dataset("anton-l/superb_demo", "er", split="session1") dataset = dataset.map(map_to_array) model = HubertForSequenceClassification.from_pretrained("superb/hubert-large-superb-er") feature_extractor = Wav2Vec2FeatureExtractor.from_pretrained("superb/hubert-large-superb-er") # compute attention masks and normalize the waveform if needed inputs = feature_extractor(dataset[:4]["speech"], sampling_rate=16000, padding=True, return_tensors="pt") logits = model(**inputs).logits predicted_ids = torch.argmax(logits, dim=-1) labels = [model.config.id2label[_id] for _id in predicted_ids.tolist()]
评估指标为准确性。
