Researchers have developed a new method called Window Likelihood (WL) for training full-duplex speech models, aiming to improve their ability to handle interruptions and backchannels in conversations. Traditional methods using sequence-level Reinforcement Learning (RL) with timing rewards have shown limitations, such as credit leakage and difficulty in learning specific conversational cues. WL addresses these issues by integrating rewards in closed form and maximizing the log-probability of correct actions, leading to better performance on the HumDial-FDBench benchmark across various open models.
