Could you build this?
No Developing state-of-the-art low-latency text-to-speech models with prompt-based voice direction and zero-shot voice cloning requires proprietary model training, massive audio datasets, and specialized ML researchers.
What it would actually take: This requires designing and training neural audio codecs, diffusion models, or autoregressive audio transformers on tens of thousands of hours of studio-quality speech datasets. It requires specialized deep learning engineers, heavy GPU compute clusters for training, and custom CUDA kernels to achieve ultra-low streaming latency (<100ms). Building the model itself cannot be substituted by prompt engineering.
