The American English Speech Recognition Corpus was collected in USA.

The script contains 383,788(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 304 different speakers (152 males, 152 females) who were balanced distributed in age (mainly 18 – 30,31 – 45,46 – 65), gender and regional accents. Each speaker was recorded in 1 or 2 different environments taking among 7 possible environments (STOP_MOTOR_RUNNING, LOW_SPEED_ROUGH_ROAD, HIGH_SPEED_GOOD_ROAD, and etc.).

3 kinds of vehicle (MAZDA 6, HONDA ACCORD and HONDA CRV) and 3 kinds of Microphone (Shure SM10A / Sennheiser ME104 / AKG C400BL) were used when recording. 4 high quality audio channels were used for speech collection.

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