Researchers have developed a new method to understand how natural language instructions influence speech generation in text-to-speech (TTS) systems. By adapting the DAAM framework to speech diffusion models, the study analyzes the impact of style captions on acoustic output. The findings indicate that style tokens have lower temporal variance than content tokens and that style attention correlates with fundamental frequency and energy, with peak influence occurring in early model steps and deep layers.
