Whisper model adapted for Persian Speech Emotion Recognition with PCA

By PulseAugur Editorial · [1 sources] ·

Researchers have explored methods to improve Speech Emotion Recognition (SER) for low-resource languages like Persian, focusing on the Whisper model. Their study proposes using Principal Component Analysis (PCA) to reduce the dimensionality of Whisper's frame-level embeddings, which decreases trainable parameters and training latency without sacrificing performance. While PCA-based reduction consistently enhanced emotion recognition accuracy, fine-tuning Whisper on Persian Automatic Speech Recognition (ASR) tasks showed only minor improvements for SER, indicating limited transferability of language adaptation to emotion-specific representations.

IMPACT This research offers practical insights for efficiently using large pretrained speech models for emotion recognition in low-resource languages.
