The author proposes a perceptually motivated modification to the cepstral distance measure
(CD) based on the mel frequency scale and critical-band filtering. The new objective …

We review factors that have affected the synthesis of high-quality speech by analysis-
synthesis. The influence of a selected subset of these factors on the quality of synthesized …

Describes a new artificial speech signal (ASVQ: artificial speech by vector quantization
technique) which reflects the average characteristics of the human voice. The ASVQ is …

Este trabalho aborda o problema da avaliação objetiva de qualidade de codecs de voz na
faixa de telefonia (300-3400 Hz). São apresentados os procedimentos para as avaliações …

An artificial voice signal that reflects the average characteristics of the human voice is
described. This signal is intended for use as a test signal in the objective evaluation of …

The setting of standards requires that repeatable measurements can be made of the effect of
channel degradations on the user. If such measurements can be devised, then a link can be …

This paper considers the use of the ARMA model in speech synthesis and discusses the
quality improvement and problems in synthesized speech. First, the construction of the …

This paper proposes two new methods based on spectral distortion criteria that produce
high quality speech synthesis. One is a phoneme segment selection method using an …

The concept and algorithm of the speech wave abnormal index (SWAI) is presented to
describe the damaged degree of speech signals, which are disturbed by noise or/and …
