The goal of the Phonology Project website is to make findings, methods, and materials from a program of research in speech sound disorders available to researchers, clinicians, instructors, and students. All materials have been developed with support from the National Institute on Deafness and Other Communication Disorders (DC000496; Lawrence D. Shriberg, Principle Investigator) and a core grant to the Waisman Center from the National Institute of Child Health and Development (U54 HD090256). All materials on this website, including open-source software (Programs to Examine Phonetic and Phonologic Evaluation Records [PEPPER]), may be freely downloaded and modified, but may not be reproduced for commercial sale.
- MISSION includes the goals of the Phonology Project (1980-2019) and acknowledgements.
- RESEARCH includes copies of publications, presentations, and technical reports. The Technical Reports series includes reference data for tasks and measures developed in Phonology Project research, and findings that supplement information in presentations and publications.
- PEPPER FONTS includes several phonetic fonts for use in educational, clinical, and research documents.
- SYLLABLE REPETITION TASK (SRT) includes research documents, a PowerPoint of the assessment task, and scoring forms.
- MADISON SPEECH ASSESSMENT PROTOCOL (MSAP) includes copies of speech and other assessment tasks and forms for clinical and research applications.
- PROSODY-VOICE SCREENING PROFILE (PVSP) includes training materials for perceptual coding of a speaker’s prosody and voice features in conversational speech.
- PROGRAMS TO EXAMINE PHONETIC AND PHONOLOGIC EVALUATION RECORDS (PEPPER) is a suite of open-source software to assess [PepAssess] and classify [PepClass] a speaker’s or groups of speakers’ speech and motor speech status. The PepClass programs require information from narrow phonetic transcription, PVSP coding, and acoustic analyses. PEPPER also includes three utilities for educational, clinical, and research use. PEPAGREE provides point-to-point, intrajudge or interjudge percentages of agreement for broad or narrow phonetic transcription. PEPSTAT provides statistical options to summarize and compare findings within and between speakers and groups of speakers. PEPGRAPH provides graphical options to display findings from qualitative or quantitative analyses.
- SEARCH provides a means to retrieve information stored in any of the Phonology Project tabs other than the PEPPER tab.
