KIRA: A Full-Stack Reading Screening System with Dual-Pathway Analysis for Children

Maggie Dong, Rohit Mekkoth, Zixuan Wang +3

Early-grade reading screening is critical for identifying children at risk of reading difficulty. Existing AI-based screeners are often limited in the scope of their analyses and e…

HASS: Hierarchical Simulation of Logopenic Aphasic Speech for Scalable PPA Detection

Harrison Li, Kevin Wang, Cheol Jun Cho +13

Building a diagnosis model for primary progressive aphasia (PPA) has been challenging due to the data scarcity. Collecting clinical data at scale is limited by the high vulnerabili…

Self-Supervised Speech Models Encode Phonetic Context via Position-dependent Orthogonal Subspaces

Kwanghee Choi, Eunjung Yeo, Cheol Jun Cho +2

Transformer-based self-supervised speech models (S3Ms) are often described as contextualized, yet what this entails remains unclear. Here, we focus on how a single frame-level S3M…

HuPER: A Human-Inspired Framework for Phonetic Perception

Chenxu Guo, Jiachen Lian, Yisi Liu +9

We propose HuPER, a human-inspired framework that models phonetic perception as adaptive inference over acoustic-phonetics evidence and linguistic knowledge. With only 100 hours of…

[b] = [d] - [t] + [p]: Self-supervised Speech Models Discover Phonological Vector Arithmetic

Kwanghee Choi, Eunjung Yeo, Cheol Jun Cho +2

Self-supervised speech models (S3Ms) are known to encode rich phonetic information, yet how this information is structured remains underexplored. We conduct a comprehensive study a…

Teaching Machines to Speak Using Articulatory Control

Akshay Anand, Chenxu Guo, Cheol Jun Cho +2

Current speech production systems predominantly rely on large transformer models that operate as black boxes, providing little interpretability or grounding in the physical mechani…

LCS-CTC: Leveraging Soft Alignments to Enhance Phonetic Transcription Robustness

Zongli Ye, Jiachen Lian, Akshaj Gupta +18

Phonetic speech transcription is crucial for fine-grained linguistic analysis and downstream speech applications. While Connectionist Temporal Classification (CTC) is a widely used…

Towards Accurate Phonetic Error Detection Through Phoneme Similarity Modeling

Xuanru Zhou, Jiachen Lian, Cheol Jun Cho +12

Phonetic error detection, a core subtask of automatic pronunciation assessment, identifies pronunciation deviations at the phoneme level. Speech variability from accents and dysflu…

K-Function: Joint Pronunciation Transcription and Feedback for Evaluating Kids Language Function

Shuhe Li, Chenxu Guo, Jiachen Lian +18

Evaluating young children's language is challenging for automatic speech recognizers due to high-pitched voices, prolonged sounds, and limited data. We introduce K-Function, a fram…

Analyzing The Language of Visual Tokens

David M. Chan, Rodolfo Corona, Joonyong Park +3

With the introduction of transformer-based models for vision and language tasks, such as LLaVA and Chameleon, there has been renewed interest in the discrete tokenized representati…

Time and Tokens: Benchmarking End-to-End Speech Dysfluency Detection

Xuanru Zhou, Jiachen Lian, Cheol Jun Cho +10

Speech dysfluency modeling is a task to detect dysfluencies in speech, such as repetition, block, insertion, replacement, and deletion. Most recent advancements treat this problem…

Stutter-Solver: End-to-end Multi-lingual Dysfluency Detection

Xuanru Zhou, Cheol Jun Cho, Ayati Sharma +9

Current de-facto dysfluency modeling methods utilize template matching algorithms which are not generalizable to out-of-domain real-world dysfluencies across languages, and are not…
