In mood disorder diagnosis, bipolar disorder (BD) patients are often misdiagnosed as unipolar depression (UD) on initial presentation. It is crucial to establish an accurate distinction between BD and UD to make a correct and early diagnosis, leading to improvements in treatment and course of illness. To deal with this misdiagnosis problem, in this study, we experimented on eliciting subjects’ emotions by watching six eliciting emotional video clips. After watching each video clips, their speech responses were collected when they were interviewing with a clinician.

In Mandarin language speaking, some consonant and vowel pairs are hard to be distinguished and pronounced clearly even for some native speakers. This study investigates the signal distance between consonants compared in pairs from the signal processing point of view to reveal the correlation of signal distance and consonant pronunciation. Some popular speech quality objective measures are innovatively applied to obtain the signal distance.

Speech production requires control for coordination among different articulatory organs. During the natural speech, the articulatory co-variation is more common rather than compensation, but the studies supporting this view are few. In this study, the coordination of lip and tongue articulation was examined during speech using articulatory data. Native speakers of Chinese served as subjects. Speech materials consisted of short Chinese sentences, which include words having the cardinal vowels at different locations in sentences with and without emphasis.

This study aims at examination on the relationship between the
perception and production of Mandarin tone by Kazak minor
learners from China. The eight-day perceptual training course
of Mandarin tone is designed. Perception is assessed by means
of identification test. Production data is collected both at
pretest and post-test, and evaluated by native speakers of
Mandarin Chinese. The results from the perception at pretest
and post-test reveal that training Kazak learners to perceive
Mandarin tones has been shown to be effective, with

Directions into Velocities of Articulators (DIVA) model is a kind of self-adaptive neural network model which controls movements of a simulated vocal tract to produce words, syllables or phonemes. However, DIVA model lacks of emotion functions. To implement the emotion function in DIVA model, we investigate the process of affective speech production based on the combination of fundamental frequency (F0) and formant frequencies, as well as the relations between F0 and formants of emotional speech.

The main object of this study is voice quality after total thyroidectomy (which involves complete removal of the thyroid gland) or isthmolobectomie (which involves removal of the half, right or left, portions of the gland). This often causes degradation of voice quality permanently or temporarily. Voice quality will be studied using aerodynamic cues. From an aerodynamic point of view, oral airflow (Oaf) and maximum phonation time (TMP) were observed.

Electric Network Frequency is the frequency of power distribution networks in power grids that fluctuates about a nominal value with respect to the changing loads.Its ubiquitous nature has made notable contributions to forensic analysis that has substantiated its use as a significant tool in this area. In this paper we have proposed a technique to identify the power grid in which the ENF containing signal was recorded, without the assistance of concurrent power references.

Testing complex digital signal processors (DSPs) requires a development platform with sufficient
signal bandwidth and system performance to fully exercise the DSP. Without a development plat-
form, verification of DSPs would be limited to monitoring test output signals for an indication of
performance and successful operation. In addition, a development platform with high-speed analog
input and output interfaces to the DSP system allows it to be used directly in many sophisticated
