UCLA: SPAPL CVs

Consonant Vowel Tokens

An extensive database of 1,728 isolated CVs is available through this website. 8 tokens for each of 18 consonants in 3 vowel contexts were digitally recorded from 4 talkers (2 males and 2 females).

Directories and filenames describe the CV and the talker. The three vowel contexts are labeled in ascii as:

The 18 consonant contexts are labeled in ascii as: The CV directory includes 46 subdirectories containing each CV combination from the 18 consonants and 3 vowels. The name of the subdirectory is the concatonation of the CV (ba, da, SHee, etc.). Within each subdirectory there are 8 exemplars from each of the 4 talkers. These files are named CV.n.SU, where the CV matches the name of the subdirectory, n is the token number, and SU is the identification for each subject. Subjects "peg" and "jb" are female, and "bh" and "bps" are male.

The data files contain raw big-endian short integer data, with no header. The sampling rate is 16 kHz.
