We used the dataset collected through the following task.
- No. 10063424, 'development of distant speech recognition and multi-task dialog processing technologies for in-door conversational robots'
Specification
- Korean read speech corpus (ETRI read speech)
- Clean speech at a distance of 1m and a direction of 0 degrees
- 16kHz, 16bits
We uploaded multi-resolution cochleagram (MRCG) features extracted from the above dataset.
python based MRCG feature extraction toolkit is used.
