Emergent emotion via neural computational energy conservation on a humanoid robot
(IEEE, 2013)This paper presents our initial work on how emotion based behaviors may emerge through computational mechanisms. We hold that in addition to basic emotions such as anger and fear that serves bodily well being of the organism, ... -
Hybrid statistical/unit-selection Turkish speech synthesis using suffix units
(Springer International Publishing, 2016-12)Unit selection based text-to-speech synthesis (TTS) has been the dominant TTS approach of the last decade. Despite its success, unit selection approach has its disadvantages. One of the most significant disadvantages is ... -
SAS : A speaker verification spoofing database containing diverse attacks
(IEEE, 2015)This paper presents the first version of a speaker verification spoofing and anti-spoofing database, named SAS corpus. The corpus includes nine spoofing techniques, two of which are speech synthesis, and seven are voice ... -
Natural language features for detection of Alzheimer's disease in conversational speech
(IEEE, 2014)Automatic monitoring of the patients with Alzheimer's disease and diagnosis of the disease in early stages can have a significant impact on the society. Here, we investigate an automatic diagnosis approach through the use ... -
Analysis of speech-based measures for detecting and monitoring Alzheimer’s disease
(Springer Science+Business Media, 2014)Automatic diagnosis of the Alzheimer’s disease as well as monitoring of the diagnosed patients can make significant economic impact on societies. We investigated an automatic diagnosis approach through the use of speech ... -
Hybrid nearest-neighbor/cluster adaptive training for rapid speaker adaptation in statistical speech synthesis systems
(International Speech Communication Association, 2013)Statistical speech synthesis (SSS) approach has become one of the most popular methods in the speech synthesis field. An advantage of the SSS approach is the ability to adapt to a target speaker with a couple of minutes ... -
Gauss karışım modeli tabanlı konuşmacı belirleme sistemlerinde klasik MAP uyarlanması yönteminin performans analizi
(IEEE, 2010)Gaussian mixture models (GMM) is one of the most commonly used methods in text-independent speaker identification systems. In this paper, performance of the GMM approach has been measured with different parameters and ... -
ÖZÜ konuşmacı doğrulama sisteminin çok sınıflı senaryoda NIST 2010 veritabanı ile başarımı
(IEEE, 2011)Performance of the speaker verification systems is typically measured based on their binary decision accuracy. However, in speaker verification applications where close to %100 accuracy is required, such as the systems ... -
Finding relevant features for statistical speech synthesis adaptation
(European Language Resources Association, 2014-05)Statistical speech synthesis (SSS) models typically lie in a very high-dimensional space. They can be used to allow speech synthesis on digital devices, using only few sentences of input by the user. However, the adaptation ... -
Konuşmacı aradeğerlemeli SMM tabanlı metinden konuşma sentezleme si̇stemi
(IEEE, 2011)Hidden Markov Model (HMM) based text-to-speech (TTS) systems offer many advantages compared to the concatenative approach. One of those advantages is the ability to interpolate between different speakers to generate new ... -
Vurgu ve söyleyiş modelleme hatalarının SMM tabanlı Türkçe MKS sistemindeki etkileri
(IEEE, 2011)SMM tabanlı metinden konuşma sentezleme (SMM-MKS) yöntemi, gün geçtikçe daha 1 fazla araştırmacısının ilgisini çekmektedir. Bu yöntemin en önemli avantajlarından biri, birim seçmeli sistemlerde görülen bozulma etkilerinin ... -
Gauss karışım modeli tabanlı konuşmacı doğrulama sistemlerinde kişiye ve kanala uyarlanmada klasik MAP tabanlı yöntemlerin performans analizi
(IEEE, 2011)In this paper, performance of Gaussian mixture models (GMM) based algorithms implemented in Speech Processing Laboratory at Ozyegin University, within NIST SRE2004 and 2006 database was reported. Gaussian mixture models ... -
Detection of Alzheimer's disease using prosodic cues in conversational speech
(IEEE, 2014)Automatic diagnosis of the Alzheimer's disease as well as monitoring of the diagnosed patients can make significant economic impact on societies. We investigated an automatic diagnosis approach through the use of speech ... -
Synthesis of clock trees for sampled-data analog IC blocks
(IEEE, 2013)This paper describes a methodology for automated design of clock trees in Sampled-Data Analog Circuits (SDACs). The current practice in the industry and academia for clock tree design of SDACs is a manual process, which ... -
Combined AES + AEGIS architectures for high performance and lightweight security applications
(Springer International Publishing, 2014)AES has been the prominent block cipher since its introduction as the standard. It has been the cipher used in almost all new applications that require solid, unbreakable security with reasonable resource usage. Several ... -
A robotics summer camp for high school students: pipelines activities promoting careers in engineering fields
(American Society for Engineering Education, 2013-06)In this paper we discuss the lived-experiences and the career interests of 27 high school students who participated in a two-week Robotics summer camp in 2012. The summer camp was designed by a team of engineering faculty, ... -
Enabling difference-based dynamic partial self reconfiguration for large differences
(IEEE, 2013)This paper presents a new Dynamic Partial Self Reconfiguration (DPSR) flow for Xilinx FPGAs. Leveraging the Xilinx FPGA Editor and PlanAhead tools, we provide two implementation approaches that enable partial reconfiguration ... -
FPGA bitstream protection with PUFs, obfuscation, and multi-boot
(IEEE, 2011)With the combination of PUFs, obfuscation, and multi-boot, we are able to do the equivalent of partial bitstream encryption on low-cost FPGAs, which is only featured on high-end FPGAs. Low-cost FPGAs do not even have ... -
Cost-benefit approach to degradation of electrolytic capacitors
(IEEE, 2014)Aluminum electrolytic capacitors are widely used as a filter or bulky capacitor after rectification stages of switching power supplies (SMPS). Fly-back, forward, and resonant converter topologies, which are widely used in ... -
Femto hücre erişim noktaları için uygulama bazlı takvimleyicilerin önemi
(IEEE, 2012)In this paper, it is proposed that in order to guarantee a certain level of Quality of service (QoS) for different applications in a femtocell network, it is necessary to use application-based scheduling in femtocell access ...
