Disordered Voice Database and Program, Model 4337Kay Elemetrics has recorded to CD-ROM a database developed by the Massachusetts Eye and Ear Infirmary (MEEI) Voice and Speech Lab. The Disordered Voice Database, Model 4337, includes more than 1,400 voice samples (i.e., sustained “ah” and first 12 seconds of Rainbow Passage) from approximately 700 subjects. This database is developed as an aid in the acoustical and perceptual analysis of disordered voices for either clinical or research applications. The database includes samples from patients with a wide variety of organic, neurological, traumatic, psychogenic, and other voice disorders.
The Disordered Voice Database and Program The DatabaseMEEI provides an excellent model for the organization of patient and examination information. Kay selected a larger representative collection of examinations with a comprehensive set of information about the patient, MDVP results, acoustic samples and diagnosis by the professionals at MEEI. All of the signal files and clinical information for the disordered voices were collected and structured at MEEI Voice and Speech Lab. Virtually all patients had extensive vocal function analysis including stroboscopy, aerodynamic analysis, and acoustic analysis. These samples with associated data and evaluations represent many years of work. Kay added the normal subjects. All samples were collected in a controlled environment (low ambient noise, constant microphone distance, direct digital 16-bit sampling, robust signal conditioning, and a 25- or 50-kHz sampling rate). The ProgramIncluded with the database is a custom program using tools from MDVP and CSL/Multi-Speech to fully explore the voice parameters and acoustic properties. Additionally, a full set of features is available to develop critical listening for voicing characteristics.

database in Excel format. Spreadsheets include patient, Learning to Hear Voice CharacteristicsThe ability of the program to directly recall the database while performing comprehensive acoustic analysis has obvious benefits. An overlooked benefit of the Disordered Voice Database and Program is that the users can use the high quality audio examples and analysis results to help train their ear to hear voice characteristics. Both the sustained vowel and read passage can be listened to and compared to the analysis repeatedly to improve listening skills. ApplicationsFor the first time, hospitals and universities can have quick and ready access, in convenient CD-ROM format, to an extensive database collected using a rigorous protocol and direct digital recording techniques. All acoustic files can be directly loaded into all CSL and Multi-Speech programs. The CD-ROM includes complete patient file information and MDVP analysis results in FoxPro format (with FoxPro viewing template), Excel format, or as ASCII files.
The figure above is from the Excel spreadsheet included with the database. All exams have MDVP parameters which can be sorted and selected for studies, ear training, or to educate users about MDVP parameters. Details
Summary The Disordered Voice Database provides inexpensive access to a rich resource of information about voice patients and the acoustic parameters associated with pathological voice. The program facilitates easy access to this database. Current CSL, Model 4500 and 4150, software and database options include:
