Pixel-TTS: Image based Text Rendering for Robust Text-to-Speech
Researchers have introduced Pixel-TTS, a novel text-to-speech framework that renders text as images to generate speech embeddings. This approach leverages visual cues, allowing the model to better handle characters with similar visual forms but different Unicode encodings, which is beneficial for cross-lingual and zero-shot applications. Unlike traditional methods that treat characters independently, Pixel-TTS improves robustness to unseen characters and orthographic variations, demonstrating competitive performance, faster convergence, and strong zero-shot generalization in experiments.
