The Japanese Speech Recognition Corpus was collected in Japan.

The corpus contains 200,696(approx.) utterances in total, specially designed to provide materials for both training and testing of speech recognizers. Each utterance wave was stored in a separate file and uncompressed.

This corpus contains the voices of 100 different speakers (50 males, 50 females) who were balanced distributed in age (18 – 30, 31 – 45, 46 – 60), gender and regional accents.
