Utterance Level

Utterance-level analysis in speech processing focuses on understanding and modeling the information contained within individual spoken turns, going beyond simple frame-level acoustic features. Current research emphasizes learning disentangled representations that separate semantic content from speaker characteristics and other utterance-level attributes, often employing transformer-based models, contrastive learning, and variational autoencoders. This work is crucial for improving various applications, including speech recognition, text-to-speech synthesis, emotion recognition, and dialogue systems, by enabling more nuanced and context-aware processing of conversational data. The development of robust and efficient methods for utterance-level analysis is driving advancements in human-computer interaction and natural language understanding.
