The rapid evolution of large language models (LLMs) is revolutionizing text-to-speech technology, moving beyond robotic voices to ones that can convey emotions. Research articles and model analyses offer insights into how LLMs achieve this transformation, highlighting the progression from basic speech systems to sophisticated deep learning models that learn from vast speech data. Customization options and multilingual support are expanding, enhancing accessibility worldwide. The integration of LLMs with other AI technologies blurs disciplinary boundaries, emphasizing efficiency and cost reduction for broader adoption. As artificial voices increasingly resemble human speech, the implications for human-technology interactions and creative opportunities are profound and thought-provoking. The future promises exciting possibilities as the distinction between human and artificial voices continues to blur.
