Voice-AttentionNet Architecture
Our proposed Lightweight Attention-Based Temporal-CNN (Voice-AttentionNet) combines the strengths of Temporal-CNNs for local feature extraction with a novel attention mechanism for global dependency modeling. This architecture is specifically designed to recognize pathological features in speech, outperforming traditional models by dynamically adjusting channel weights and enhancing feature representation. We reduced convolution layers from 7 to 4, simplified upsampling, employed regularization (Dropout), and adopted the Gaussian Error Linear Unit (GeLU) activation function for improved stability and nonlinear representation. The integrated lightweight SE attention mechanism further refines feature extraction while minimizing computational overhead.
Advanced Data Processing
The system processes raw time-domain audio signals by converting them into Mel spectrograms. This crucial step compresses high-dimensional raw data into a fixed-size two-dimensional matrix (time × frequency), significantly reducing data dimensionality while preserving meaningful information. We utilize Mel frequency, which closely aligns with human auditory perception, offering high resolution in low-frequency regions and lower resolution in high-frequency regions. By setting 64 Mel filter channels, the process simulates human ear hearing characteristics, effectively highlighting key features in the speech signal for disease detection.
Robust Loss Functions
To optimize model performance, particularly in scenarios with class imbalance, we introduced a novel voice-based loss function (Lv). This combines Cross-Entropy Loss for multi-class classification, Focal Loss to reduce the weight of easy-to-classify samples and increase focus on hard-to-classify minority samples, and Label Smoothing Loss to prevent model overconfidence and improve generalization. This multi-loss approach provides a smoother gradient during training, helping the model learn features from minority classes effectively and mitigating issues like gradient explosion.

Voice-AttentionNet in Clinical Diagnostics
Challenge: The challenge was to develop a non-invasive, efficient system for early detection of multiple diseases from voice data, overcoming limitations of traditional methods and subtle disease manifestations.
Solution Implemented: We implemented Voice-AttentionNet, a Lightweight Attention-Based Temporal Convolutional Neural Network. This system processes raw patient voice data, transforms it into Mel spectrograms, and uses its advanced architecture with a tailored multi-loss function to make preliminary predictions for five major disease categories.
Impact & Results: The system provides initial determinations for liver complaint, lung disease, Parkinson's disease, sinus arrhythmia, and thyroid disease. This preliminary prediction capability assists medical professionals in making faster, more informed final diagnoses, reducing the burden on healthcare systems and enabling timely patient treatment. The model's high accuracy (especially 100% for Parkinson's disease) highlights its potential as an AI-driven diagnostic tool.
