This demonstration illustrates the inharmonic vowels used by de Cheveigné to study double vowel identification. The software used to synthesize these vowels is courtesy of Alain de Cheveigné.
Here is a demonstration of double vowels. The vowels illustrated here are the japanese vowels used by de Cheveigné and colleagues in a series of studies discussed in the book. The software used to generate these vowels was supplied by Alain de Cheveigné.
