Contents

The 1600 spoken words (20 words times 20 sets times 4 ranks) reconstructed from the "NTT - Tohoku University Familiarity-controlled Word Lists (FW03)" and edited under the following 5 conditions:

• Pseudo speech noise is superposed with four conditions (S/N ratio: 3, 0, -3, -6 dB).
• No noise superposition.

A part of this data set is contained in the 5 audio CD’s for the convenience of the examination, etc.*1

Speaker

4 trained Japanese speakers including 2 males and 2 females; each word is spoken once.

Speech file format

WAV format (48 kHz, 16 bit, Mono)

Distribution media

1 DVD and 5 audio CDs

Licensing

For research and development purposes only

Price

11 429 yen (plus consumption tax for a domestic order)

Supplements

The programs for sound pressure level transformation and noise superposition are included in the DVD.

*1 Noise data is superposed on the 800 words (20 words times 10 sets times 4 ranks) spoken by a female speaker under 5 conditions (no noise, +3 dB, 0 dB, -3 dB, -6 dB).

*2 The sound pressure level criteria are different for this FW07 and the formerly distributed FW03. FW07 is about 6 dB lower than FW03.
