SpEAR (Speech Enhancement and Assessment Resource) Database
http://ee.ogi.edu/NSEL/ (Beta Release v1.0)
The SpEAR Database contains carefully selected samples of noise corrupted speech with clean speech references. This beta version is a small initial release of the database to allow feedback for future developments of this resource.
All speech and noise sources have been acoustically combined and re-recorded. Synchronous clocking is used to provide an exact time-aligned reference to the clean speech signal (see Technical Details).
Original Speech Files (TIMIT/)
Noisy Speech Recordings (Noisy_Recordings/)- Recorded speech and recorded noise: acoustically combined and re-recorded. Various noise sources and different SNR levels.
Lombard Speech (Lombard/) - Live speech in a noisy environment. Recorded noise sources are used to allow extraction of a cleaned speech reference.
Monaural Recordings (Monaural/) - Two recorded speech signals: acoustically combined and re-recorded.
Future releases will contain a more substantial number of samples, additional additive noise sources, cellular and coding noise, etc.
Use of this data is free, but should be referenced in all publications as follows:
