LLMs aligned for TTS-friendly text generation using FaST framework

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a method to make Large Language Models (LLMs) generate text that is more suitable for Text-to-Speech (TTS) systems. This approach frames the problem as a preference alignment task, aiming to directly optimize LLMs for spoken delivery rather than relying on post-generation rewriting. The study introduces new datasets and an evaluation suite that includes heuristic metrics, a TTS-to-ASR pipeline, and human listening studies. Experiments showed that the Feature-aware Sampling and Tuning (FaST) framework offered the best balance between TTS-friendliness and helpfulness. AI

IMPACT Improves the naturalness and usability of LLM-generated speech, potentially enhancing voice assistants and audio content creation.

    Ready to Speak: Aligning LLMs for TTS-Friendly Text Generation

    arXiv:2609.01246v1 Announce Type: new Abstract: Current Large Language Models (LLMs) are primarily optimized for written text, often producing outputs that are grammatically correct and helpful yet poorly suited for spoken delivery via Text-to-Speech (TTS). In this work, we study…
