Practical Solutions and Value of MELLE in Text-to-Speech Synthesis
Introduction
In the realm of Large language models (LLMs), there has been a significant transformation in text generation, prompting researchers to explore their potential in audio synthesis.
Challenges in Text-to-Speech (TTS) Synthesis
Adapting large language models for text-to-speech (TTS) tasks while maintaining high-quality output poses several challenges, hindering the efficiency and quality of audio synthesis, particularly in zero-shot TTS tasks that require multi-lingual, multi-speaker, and multi-domain capabilities.
Recent Advancements
Recent advancements focus on zero-shot TTS capabilities, aiming to improve robustness and stability. However, existing methods often struggle to maintain audio quality or efficiently handle multi-speaker, multi-lingual scenarios.
MELLE: A Unique Approach
MELLE is a unique approach to text-to-speech synthesis, utilizing continuous-valued tokens based on mel-spectrograms. It aims to overcome the limitations of discrete codec codes by directly generating continuous mel-spectrogram frames from text input.
Key Features of MELLE
MELLE employs regression loss with a spectrogram flux loss function instead of cross-entropy loss, facilitating sampling mechanisms in continuous space and enhancing output diversity and model robustness.
Performance Comparison
MELLE demonstrates superior performance in zero-shot speech synthesis tasks compared to existing models, achieving better robustness and speaker similarity.
Advantages of MELLE
MELLE’s architecture integrates several innovative components for efficient text-to-speech synthesis, offering a streamlined, single-pass approach that potentially surpasses previous methods in both quality and efficiency.
