As one of the major Chinese dialects, Shanghainese is well known for its complex tone sandhi system. This paper applies the command-response model to represent F0 contours of Shanghainese speech. Analysis-by-Synthesis is conducted both on carrier sentences with monosyllabic target words and on isolated polysyllabic words, from which a set of appropriate tone command patterns is derived for word...

Telecommunications networks are exposed to a plethora of accents and languages. Fundamental to current and future systems are low rate speech coders. This paper examines the problems associated with speech coding of different languages and accents. Our investigations show that most low-rate (8kb/s and below) speech coders show bias towards non-accented English. When the coders are used for heav...

Personality has a huge effect on how we communicate and interact with others. This study is one in a series of three that investigates how a speech based in-car system matched with dominant and submissive drivers affects performance and attitude drivers. The study was conducted with 30 participants at Linköping University in Sweden. Data show that using a voice that combines feature from submis...

This is a review of some work carried out over the last decades at the Speech Music Hearing Department, KTH, where the analysis-by-synthesis strategy was applied to singing. The origin of the work was a hardware synthesis machine combined with a control program, which was a modified version of a textto-speech conversion system. Two applications are described, one concerning vocal loudness varia...

We focus on variations in the aerodynamics of airflow patterns in the laryngeal ventricle and the false vocal folds based on a physical model for the classification of neutral and stressed speech. We modify the two-mass model to include the laryngeal ventricle, and the physical parameters characterizing airflow variations in the laryngeal ventricle under psychological stress are explored. The t...

Speech and audio coding underlie many of the products and services that we have come to rely on and enjoy today. In this chapter, we discuss speech and audio coding, including a concise background summary, key coding methods, and the latest standards, with an eye toward current limitations and possible future research directions.

This article intends to study the influence of two parameters (language and speech task) on the manifestation of creaky voice among six American women learning French. The speakers were recorded in both reading and spontaneous conditions, in English and French. These languages were chosen for their difference at the phonatory level. The number of creaky voice occurrences, and creakiness timing ...

Kei Kikuiri, Nobuhiko Naka and Shinya Abe The high-quality speech coding is a super-wideband speech coding technique for providing high-quality VoIP services in a high-speed wireless communication environment, and was developed in collaboration with DoCoMo Communications Laboratories USA, Inc. This technology encodes and transmits nearly all of the frequency components of the human voice to all...
