• Title: EdiTTS: Score-based Editing for Controllable Text-to-Speech
• Authors: Jaesung Tae, Hyeongju Kim, Taesu Kim
• Abstract summary: EdiTTS is an off-the-shelf speech editing methodology based on score-based generative modeling for text-to-speech synthesis. We apply coarse yet deliberate perturbations in the Gaussian prior space to induce desired behavior from the diffusion model. Listening tests demonstrate that EdiTTS is capable of reliably generating natural-sounding audio that satisfies user-imposed requirements.

• Abstract: We present EdiTTS, an off-the-shelf speech editing methodology based on score-based generative modeling for text-to-speech synthesis. EdiTTS allows for targeted, granular editing of audio, both in terms of content and pitch, without the need for any additional training, task-specific optimization, or architectural modifications to the score-based model backbone. Specifically, we apply coarse yet deliberate perturbations in the Gaussian prior space to induce desired behavior from the diffusion model, while applying masks and softening kernels to ensure that iterative edits are applied only to the target region. Listening tests demonstrate that EdiTTS is capable of reliably generating natural-sounding audio that satisfies user-imposed requirements.

  Text-based speech editing (TSE) allows users to modify speech by editing the corresponding text and performing operations such as cutting, copying, and pasting. Current TSE techniques focus on minimizing discrepancies between generated speech and reference targets within edited segments. seamlessly integrating edited segments with unaltered portions of the audio remains challenging. This paper introduces a novel approach, FluentEditor$tiny +$, designed to overcome these limitations.

  We present a Diffusion GAN based approach (Prosodic Diff-TTS) to generate the corresponding high-fidelity speech based on the style description and content text as an input to generate speech samples within only 4 denoising steps. We demonstrate the efficacy of our proposed architecture on multi-speaker LibriTTS and PromptSpeech datasets, using multiple quantitative metrics that measure generated accuracy and MOS.

  Text-based speech editing (TSE) techniques are designed to enable users to edit the output audio by modifying the input text transcript instead of the audio itself. We propose a fluency speech editing model, termed textitFluentEditor, by considering fluency-aware training criterion in the TSE training. The subjective and objective experimental results on VCTK demonstrate that our textitFluentEditor outperforms all advanced baselines in terms of naturalness and fluency.
