These disorders affect people of all ages with or without hearing impairment, including children with autism, those who stutter, and adults with aphasia or speech disorders. The NIDCD Voice, Speech, and Language Program uses a wide range of research approaches to develop effective diagnostic and intervention strategies for individuals with communication impairments.

Research in voice and speech includes studies to determine the nature, causes, treatment, and prevention of disorders of motor speech production throughout the lifespan.

Research in language and language disorders includes studies on characterization, genetic and brain causes, and diagnostic and treatment approaches relevant to communication across the lifespan. Breadcrumb Home Research Extramural Research. Other spreadsheets are also included. Other spreadsheets separate out each voice quality by scale.

According to Nagle , ratings within one centimeter 10 units on the CAPE-V is considered to be adequate agreement. Please take the standard deviation of ratings into account when looking at each file individually. Because averages across all raters were used to categorize each sample, the following thresholds were used: Any user is free to change these thresholds as necessary.

To help a user change the thresholds, I have provided the formula I used to automatically label each sample in the spreadsheet. Rater Listener Reliability Inter- and intra-rater reliability calculations are provided for the sample as a whole using Intraclass Correlations. Most files were rated by three experienced voice clinicians.

Some files were rated by four experienced voice clinicians. A computerized speech lab program was used to extract MDVP parameters as features, and an acoustical analysis was performed. The Fisher discrimination ratio was applied to rank the parameters. A t test was performed to highlight any significant differences in the means of the normal and pathological samples.

Results: The experimental results demonstrate a clear difference in the performance of the MDVP parameters using these databases.
