Abstract

Audio token modeling has become a powerful framework for speech synthesis, with two-stage approaches employing semantic tokens remaining prevalent. In this paper, we aim to simplify this process by introducing a semantic knowledge distillation method that enables high- quality speech generation in a single stage. Our proposed model improves speech quality, intelligibility, and speaker similarity compared to a single- stage baseline. Although two-stage systems still lead in intelligibility, our model significantly narrows the gap while delivering comparable speech quality. These findings showcase the potential of single-stage models to achieve efficient, high-quality TTS with a more compact and streamlined architecture.

Demos

The following examples are selected from the listening test described in the paper, which are generated from LibriSpeech test-clean subset. The models to compare include the one-stage model without semantic knowledge distillation (NARSiSbase), one-stage model with semantic knowledge distillation (NARSiSavg), and the two-stage model (NAR 2-stage).
