Reliable Neural-Codec Text-to-Speech by ASR Self-Verification and Distillation: Near-Zero Catastrophic Failures Across Models and Codecs

Asaria, Salomone, Gandhi·June 16, 2026AUDIOLLM

ASR-based self-verification drives catastrophic failures (silence, early termination, repetition) to near zero in autoregressive neural-codec TTS, then distills the behavior for inference-time efficiency — generalizing across four TTS systems and three codecs.
