This paper addresses a classical but important problem: The coupling of lexical tones and sentence intonation in tonal languages, such as Chinese, focusing particularly on voice fundamental frequency (F1) contours of speech. It is important because it forms the basis of speech synthesis technology and prosody analysis. We provide a solution to the problem(More)
AIM To develop a simple screening test to identify older adults at high risk for sarcopenia. METHODS We studied 1971 functionally independent, community-dwelling adults aged 65 years or older randomly selected from the resident register of Kashiwa city, Chiba, Japan. Data collection was carried out between September and November 2012. Sarcopenia was(More)
In order to incorporate long temporal-frequency structure for acoustic event detection, we have proposed a spectral patch based learning and representation method. The learned spectral patches were regarded as acoustic words which were further used in sparse encoding for acoustic feature representation and modeling. In our previous study, during feature(More)
OBJECTIVES To determine age- and sex-specific body composition reference values and investigate age differences in these parameters for community-dwelling older Japanese men and women, using direct segmental multi-frequency bioelectrical impedance analysis. METHODS We conducted a pooled analysis of data collected in four cohort studies between 2008 and(More)
This paper describes a new concatenative TTS system under development at ATR. The system, named XIMERA, is based on corpus-based technologies, as was the case for the preceding TTS systems from ATR, namely ν-talk and CHATR. The prominent features of XIMERA are (1) large corpora (a 110-hours corpus of a Japanese male, a 60-hours corpus of a Japanese female,(More)
In this paper, we describe the ATR multilingual speech-to-speech translation (S2ST) system, which is mainly focused on translation between English and Asian languages (Japanese and Chinese). There are three main modules of our S2ST system: large-vocabulary continuous speech recognition, machine text-to-text (T2T) translation, and text-to-speech synthesis.(More)
This paper proposes a novel unit selection algorithm for Japanese Text-To-Speech (TTS) systems. Since Japanese syllables consist of CV (C: Consonant, V: Vowel) or V, except when a vowel is devoiced, CV units are basic to concatenative TTS systems for Japanese. However, speech synthesized with CV units sometimes have discontinuities due to V-V concatenation;(More)
