Hierarchical dynamic coding coordinates speech comprehension in the human brain Open
Speech comprehension involves transforming an acoustic waveform into meaning. To do so, the human brain generates a hierarchy of features that converts the sensory input into increasingly abstract language properties. However, little is kn…

Distinct paths to false memory revealed in hundreds of narrative recalls Open
Memory distortions emerge from a complex interplay between prior knowledge and ongoing experience—dynamics which are not readily provoked in controlled laboratory experiments. Here we investigate naturally occurring memory distortions usin…

Features underlying speech versus music as categories of auditory experience Open
Classifying whether an auditory signal is music or speech is important for both humans and computer systems and critical for many applications. Though previous literature suggests that music and speech are easily separable categories, our …

Spectrotemporal Modulation: Efficient and Interpretable Feature Representation for Classifying Speech, Music, and Environmental Sounds Open
Audio DNNs have demonstrated impressive performance on various machine listening tasks; however, most of their representations are computationally costly and uninterpretable, leaving room for optimization. Here, we propose a novel approach…

Chunking Constrains Prediction during Language Comprehension Open
Spoken language is a rapid sequence of auditory information that can incorporate complicated internal structures. Prediction and chunking are two possible mechanisms for the brain to process speech efficiently, and they are often viewed as…

Complex Impact of Stimulus Envelope on Motor Synchronization to Sound Open
The human brain tracks temporal regularities in acoustic signals faithfully. Recent neuroimaging studies have shown complex modulations of synchronized neural activities to the shape of stimulus envelopes. How to connect neural responses t…

Endogenous auditory and motor brain rhythms predict individual speech tracking Open
Slow, endogenous brain rhythms in auditory cortex are hypothesized to track acoustic amplitude modulations during speech comprehension. Temporal predictions from the motor system are thought to enhance this tracking. However, direct eviden…

Asymmetric Sampling in Time: Evidence and perspectives Open
Auditory and speech signals are undisputedly processed in both left and right hemispheres, but this bilateral allocation is likely unequal. The Asymmetric Sampling in Time (AST) hypothesis proposed a division of labor that has its neuroana…

Temporally Dissociable Neural Representations of Pitch Height and Chroma Open
The extraction and analysis of pitch underpin speech and music recognition, sound segregation, and other auditory tasks. Perceptually, pitch can be represented as a helix composed of two factors: height monotonically aligns with frequency,…

Multimodal Machine Learning Can Predict Videoconference Fluidity and Enjoyment Open
Videoconferencing is now a frequent mode of communication in both professional and informal settings, yet it often lacks the fluidity and enjoyment of in-person conversation. This study leverages multimodal machine learning to predict mome…

Time-resolved hemispheric lateralization of audiomotor functional connectivity during covert speech production Open
Covert speech involves the internal generation of articulatory movements and their sensory consequences. While overt speech involves a combination of feedforward and feedback signals, feedback signals may be substantially different, or eve…

The “Naturalistic Free Recall” dataset: four stories, hundreds of participants, and high-fidelity transcriptions Open
The “Naturalistic Free Recall” dataset provides transcribed verbal recollections of four spoken narratives collected from 229 participants. Each participant listened to two stories, varying in duration from approximately 8 to 13 minutes, r…

Neural signatures of temporal anticipation in human cortex represent event probability density Open
Temporal prediction is a fundamental function of neural systems. Recent advances suggest that humans anticipate future events by calculating probability density functions, rather than hazard rates. However, direct neural evidence for this …
