Enhancing Communication & Connection for Children

The Center for Pediatric Auditory & Speech Sciences (CPASS) at ÀÖ²¥´«Ã½ Children’s advances research that helps children communicate and connect in everyday life. Based in the Delaware Valley, our center brings together expertise in speech, language, and hearing science to address communication challenges that shape development and learning.

CPASS focuses on translational research that links scientific discovery to care. We study how children produce speech and how they perceive sound. This work helps explain why communication develops differently across childhood and guides more effective ways to support it over time.

Technology plays an important role in our work. Research findings inform diagnosis and monitoring, then support the development of tools used in care and education. These efforts help clinicians, educators, and families respond more effectively to speech and hearing differences.

CPASS has a long-standing presence at ÀÖ²¥´«Ã½, with research that has evolved over decades alongside advances in pediatric care. The center also contributes to community-facing efforts, including infant auditory screening and education partnerships, while working closely with clinical teams to ensure research informs care in ways that matter to children and families.

Our research spans the continuum from basic science to applied technology. Our work focuses on communication differences in children and approaches that support assessment, treatment, and daily communication.

Focus Areas

Our research spans key focus areas:

Improving Speech Outcomes: Cleft Lip and Palate Research

We study how children with cleft lip and palate develop speech over time. By refining instrumental methods to measure outcomes, our work helps clinicians evaluate progress and guide care more precisely.

Understanding Speech Differences: Pediatric Speech Disorders Research

We examine how children produce and perceive speech across a range of developmental and neurological conditions. These insights improve how speech differences are identified and supported throughout childhood. Learn more.

Advancing Communication Tools: Assistive Speech Technology Research

We develop speech synthesis and voice banking tools for children who rely on assistive communication. This research supports meaningful expression across daily settings.

Research Themes

Our research is guided by shared priorities that shape every project:

  • From data to understanding.ÌýUsing data science and machine learning to reveal patterns in speech and hearing that improve assessment and care.
  • Designed for application. Conducting research with a clear path to clinical and educational use.
  • Child-centered outcomes. Focusing on communication, participation, and quality of life for children and families.

Related Research & Clinical Focus

Researchers at ÀÖ²¥´«Ã½ often align with multiple research areas, affiliated labs, and clinical programs to support discovery and care systemwide.

How We Make a Difference

CPASS research has shaped how pediatric speech and hearing differences are studied, measured, and supported over time. This work has influenced research and broader practice.

Notable impacts include:

  • Developed personalized synthetic voices for children and adults who rely on speech-generating devices, helping preserve identity and support meaningful communication.
  • Created widely used speech and dysarthria databases that support research worldwide and improve speech recognition for individuals with motor speech disorders.
  • Advanced instrumental methods for tracking speech outcomes in children with cleft lip and palate, supporting more precise evaluation and evidence-based care.
  • Applied data science and machine learning to reveal patterns in pediatric speech and hearing that are difficult to detect using traditional approaches.
  • Translated research into tools designed for real-world use, extending impact beyond the lab into clinical and educational settings.

Research Collaboration

Collaboration supports the longevity and reach of our research.

  • Academic partnerships with theÌý support shared scholarship and the training of future researchers.
  • Industry collaboration enables the transfer of research tools into broader use, including efforts to commercialize speech synthesis technologies we develop.
