Software development
Parts of the research efforts of the IPS involve the development of software to aid in the scientific work with speech signals and corpora.
The software is used both for basic research in speech science and for the creation of speech technology. Data collection is costly and sometimes tedious in experiments on speech production and perception. But most steps in the workflow can be drastically sped up by using and combining computer tools. Some tools have been designed specifically for single steps along the workflow, others are apt for multiple tasks. For some tasks there is a variety of tools to choose from. Some programs can be downloaded, some are offered as a web service. Web services can be used directly in the browser (more information on Web-Tools).
