Pixel-TTS: Image-based Text Rendering Enhances Speech Synthesis

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.

    Pixel-TTS: Image based Text Rendering for Robust Text-to-Speech

    arXiv:2606.14750v1 Announce Type: cross Abstract: Recent advances in pixel-based text modeling show that representing text as images enables models to exploit visual cues for language understanding. Grounding text in its visual form allows structurally similar characters with dif…
