A Differentiable Alignment Framework for Sequence-to-Sequence Modeling via Optimal Transport

arXiv — stat.MLMonday, November 24, 2025 at 5:00:00 AM
  • A novel differentiable alignment framework has been proposed for sequence-to-sequence modeling, utilizing optimal transport to enhance automatic speech recognition (ASR) systems. This framework addresses the alignment inaccuracies and peaky behavior observed in state-of-the-art models like Connectionist Temporal Classification (CTC). Experimental results indicate significant improvements in alignment accuracy across various datasets, including TIMIT, AMI, and LibriSpeech.
  • This development is crucial for applications that depend on precise ASR, such as medical speech analysis and language learning tools. By improving alignment accuracy, the new framework can lead to better performance in real-world applications, ultimately enhancing user experience and effectiveness in critical areas like healthcare and education.
  • The introduction of this framework reflects a broader trend in artificial intelligence research, where optimal transport methods are increasingly being integrated into various domains, including time-series forecasting and semantic segmentation. These advancements highlight the ongoing efforts to refine model alignment and performance, addressing challenges such as overfitting and temporal bias, which are prevalent in machine learning applications.
