摘要:

语音情感识别(SER)正在成为当今全球商业中提高服务效率的关键角色,如呼叫中心服务。最近的SER基于深度学习方法。然而,深度学习的效率取决于层的数量,即,层越深,效率越高。另一方面,较深层是梯度消失问题、低学习率和高耗时的原因。因此,本文提出了一种重新设计现有的局部特征学习块(LFLB)。新的设计被称为深度残差局部特征学习块(DeepResLFLB)。DeepResLFLB由三个级联块组成:LFLB,残差局部特征学习块(ResLFLB)和多层感知器(MLP)。LFLB用于学习局部相关性以及提取分层相关性; DeepResLFLB可以利用重复学习的优势,使用残差学习来解决消失梯度和减少过拟合,从而在更深层解释更多细节; MLP用于找到学习的关系,并发现预测语音情感和性别类型的概率。基于两个可用的已发布数据集:EMODB和RAVDESS,提出的DeepResLFLB可以显着提高性能时,通过标准指标评估:准确度,精度,召回率和F1分数。

英文摘要:

Speech Emotion Recognition (SER) is becoming a key role in global business today to improve service efficiency, like call center services. Recent SERs were based on a deep learning approach. However, the efficiency of deep learning depends on the number of layers, i.e., the deeper layers, the higher efficiency. On the other hand, the deeper layers are causes of a vanishing gradient problem, a low learning rate, and high time-consuming. Therefore, this paper proposed a redesign of existing local feature learning block (LFLB). The new design is called a deep residual local feature learning block (DeepResLFLB). DeepResLFLB consists of three cascade blocks: LFLB, residual local feature learning block (ResLFLB), and multilayer perceptron (MLP). LFLB is built for learning local correlations along with extracting hierarchical correlations; DeepResLFLB can take advantage of repeatedly learning to explain more detail in deeper layers using residual learning for solving vanishing gradient and reducing overfitting; and MLP is adopted to find the relationship of learning and discover probability for predicted speech emotions and gender types. Based on two available published datasets: EMODB and RAVDESS, the proposed DeepResLFLB can significantly improve performance when evaluated by standard metrics: accuracy, precision, recall, and F1-score.
