FlowEdit: Associative Memory for Lifelong Pronunciation Adaptation in Flow-Matching TTS
Overview
FlowEdit introduces a lifelong adaptation framework for frozen flow-matching text-to-speech (TTS) systems using Modern Hopfield Networks as content-addressable episodic memory for pronunciation corrections.
Core Methodology
Modern Hopfield Network Memory
- Content-addressable storage for corrections
- Fuzzy morphological matching via soft attention
- Fast convergence, high capacity, noise tolerance
Latent Conditioning Edits
- Token-level perturbations in text embedding space
- Learned edits rather than weight updates
- Gradient-based optimization with supervised feedback
Lifelong Learning Paradigm
- Continuous incremental corrections
- No catastrophic forgetting
- Similarity-gated retrieval
Neuroscience Foundations
Hopfield Network Analogy:
- Hippocampal pattern completion modeling
- Content-addressable recall mechanisms
- Energy-based memory dynamics
Episodic Memory Formation:
- Single-trial learning of corrections
- Cue-dependent retrieval
- Contextual binding
Experimental Results
- 312 multilingual proper nouns across 18 language families
- Phoneme Error Rate reduction: 92.7%
- Correction time: ~15 seconds
