A Theory of Response Sampling in LLMs: Part Descriptive and Part Prescriptive

ACL 2025long

Large Language Models (LLMs) are increasingly utilized in autonomous decision-making, where they sample options from vast action spaces. However, the heuristics that guide this sampling process remain under-explored. We study this sampling behavior and show that this underlying heuristics resembles…

Empathic Machines: Using Intermediate Features as Levers to Emulate Emotions in Text-To-Speech Systems

NAACL 2022long

We present a method to control the emotional prosody of Text to Speech (TTS) systems by using phoneme-level intermediate features (pitch, energy, and duration) as levers. As a key idea, we propose Differential Scaling (DS) to disentangle features relating to affective prosody from those arising due…
