background: miniature neutron sources with high neutron flux have abundant applications in medicine, industry and researches. the most important general characteristic of miniature neutron sources is their diameter which is 3mm in average. in this research, we have surveyed and designed an am-be miniature neutron source fabrication. materials and methods: this investigation resulted in creation...

The strong relation between face and voice can aid active speaker detection systems when faces are visible, even in difficult settings, the of a is not clear or there several people same scene. By being capable estimating frontal facial representation person from his/her speech, it becomes easier to determine whether he/she potential candidate for classified as an speaker, challenging cases whi...

Voice morphing based on a high fidelity VOCODER is a unique strategy to explore attributes which are closely related to biological states of speakers. Themethod is based on a temporally stable power spectral representation and spectral envelope recovery based on a new formulation of the sampling theory. The morphing algorithm itself is re-formulated to enable extrapolation without introducing p...

Systems that automatically detect voice pathologies are usually trained with recordings belonging to population of all ages. However such an approach might be inadequate because of the acoustic variations in the voice caused by the natural aging process. In top of that, elder voices present some perturbations in quality similar to those related to voice disorders, which make the detection of pa...

This paper describes the ECESS evaluation campaign of voice activity and voicing detection. Standard VAD classifies signal into speech and non-speech, we extend it to VAD+ so that it classifies a signal as a sequence of non-speech, voiced and unvoiced segments. The evaluation is performed on a portion of the Spanish SPEECON database with manually labeled segmentation. To avoid errors caused by ...

Human infants can discriminate visual and auditory stimuli solely on the basis of number, suggesting a developmental foundation for the nonverbal number representations of adult humans. Recent studies suggest that these language-independent number representations are multisensory in both adult humans and nonhuman animals. Surprisingly, however, previous studies have yielded mixed evidence conce...

This research investigated the ability of 4- and 7-month-old infants to match unfamiliar, dynamic faces and voices on the basis of age or maturity. In Experiment 1, infants received videotaped trials of an adult and a child of the same gender, side by side, speaking a nursery rhyme in synchrony with one another. The voice to one and then the other face was played in synchrony with the movements...

This study examined the development of infants' ability to perceive, learn, and remember the unique face-voice relations of unfamiliar adults. Infants of 2, 4, and 6 months were habituated to the faces and voices of 2 same-gender adults speaking and then received test trials where the faces and voices were synchronized yet mismatched. Results indicated that 4- and 6-month-olds, but not 2-month-...

In this paper we focus on improving the noise preprocessor (NPP) of the low-rate speech coder MELPe using information from the non-acoustic General Electromagnetic Motion Sensor (GEMS). A generalized linear model approach is proposed to improve the voice activity estimation both in the frame-level time domain and in the bin-level frequency domain with GEMS and context features. HMM based speech...

this study aims to investigate the semantic and syntactic features of verbs used in the introduction section of applied linguistics research articles published in iranian and international journals. a corpus of 20 research article introductions (10 from each journal) was used. the corpus was analysed for the syntactic features (tense, aspect and voice) and semantic meaning of verbs. the finding...
