Prosodic Event Recognition using Convolutional Neural Networks with Context Information
This work addresses prosodic event detection for speech processing, but it is incremental as it builds on existing CNN methods with added context features.
The paper tackled prosodic event recognition by using convolutional neural networks with context information, achieving strong results in both speaker-dependent and speaker-independent setups.
This paper demonstrates the potential of convolutional neural networks (CNN) for detecting and classifying prosodic events on words, specifically pitch accents and phrase boundary tones, from frame-based acoustic features. Typical approaches use not only feature representations of the word in question but also its surrounding context. We show that adding position features indicating the current word benefits the CNN. In addition, this paper discusses the generalization from a speaker-dependent modelling approach to a speaker-independent setup. The proposed method is simple and efficient and yields strong results not only in speaker-dependent but also speaker-independent cases.
