A recent study published on arXiv investigates whether advanced text-to-speech systems can learn social nuances, specifically the human tendency to slow speech for politeness. Researchers tested 22 synthetic voices from AI Studio and OpenAI under polite and casual conditions, finding that the polite prompts resulted in significantly slower speech across both platforms. This suggests that AI can internalize and replicate subtle psychological cues in human communication.

The paper presents MMA-Sim, a bit-accurate reference model that analyzes the arithmetic behaviors of matrix multiplication accelerators (MMAs) used in modern GPUs, specifically NVIDIA Tensor Cores and AMD Matrix Cores. With the increasing computational demands of deep neural networks (DNNs), the distinct arithmetic specifications of these MMAs can lead to numerical imprecision, affecting DNN training and inference stability. MMA-Sim reveals detailed arithmetic algorithms and confirms bitwise equivalence with real hardware through extensive validation.
