Introduction

>

The Japanese Speech Recognition Corpus was collected in Japan.

The script contains 98,632(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 308 different speakers who were balanced distributed in age, gender and regional accents. Each speaker was recorded in 2 different environments taking among 7 possible environments (STOP_MOTOR_RUNNING, LOW_SPEED_ROUGH_ROAD, HIGH_SPEED_GOOD_ROAD, and etc.).

A pronunciation lexicon with a phonemic transcription in Hepburn is available. All audio files were manually transcribed and annotated by native transcribers. The corpus follows the general convention of SpeechDat-Car.
