چکیده

The development of a visual speech apparatus that gives information about the identity of vowels spoken in a CVC context is described. The principle of the apparatus is based on a dimensional analysis of the vowel spectra. In developing the device, the demands of the specific speech correction setting of the deaf were taken into account as much as possible. From a number of physical and statistical analyses of vowels in different consonantal surroundings, it appeared possible to separate two vowels quite sitisfactorily. In describing the apparatus, special att~ention is given to some technical features that were added to satisfy the requirements of speech correction. Finally, the operation of the device is tested with a large number of monosyllables pronounced by 20 speakers. The results indicate that the apparatus satisfies the conditions stated for practical use.

Progression in infants’ vowel space: An analysis of deaf and hearing infants’ sounds

An interesting but so far neglected topic in the development of infant sound production is the hypothesized progression toward adult vowel quality. Likely, this process is quite different for normally hearing babies and for deaf babies. A band filtering analysis method is used to measure the spectral envelope in these high-pitched infants’ sounds automatically. The audio material of 5 hearing a...
