HIWIRE Database

The Hiwire project is concerned with cockpit communication and ways of improving ASR performance under adverse conditions, namely cockpit noise and non-native speech.

The Hiwire database is a non-native English database containing two kinds of speech material: a set of utterances (pilot orders) recorded in a quiet room with a close-talking microphone (clean data) and another set obtained by the addition of noise recorded in a real plane cockpit to the clean data.

8,099 English utterances have been recorded from 81 non-native speakers from France, Greece, Italy and Spain.

Clean data have been recorded in a PC using a sampling frequency of 16KHz and stored in 16 bits PCM Windows WAV format. The noise has been recorded into a Boeing 737 cockpit with a boundary microphone (AKG Q300).

This database is distributed through the ELRA catalogue http://catalog.elra.info under the reference S0293.
