Dataset Creation

Curation Rationale

The purpose of this segment of the project was to develop specific tools that would allow for automatic and semi-automatic processing of large quantities of acoustic speech data. Another purpose of the corpus was to serve as a reference for studies in phonetics and pronunciation.

Source Data

Initial Data Collection and Normalization

The corpus was recorded in a studio environment using two microphones: a high-quality studio microphone and a typical consumer audio headset.
