Objective evaluation of speech quality of text-to-speech (TTS) synthesis systems
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
Since the use of Text-to-Speech (TTS) technology is increasing, there is a high demand of TTS system that can produce natural and intelligible voice in any environments. In order to improve speech synthesis system, synthesized ...
Person recognition using humming, singing and speech
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
In this thesis, person recognition system is designed for three different speech-related biometric signals, i.e., humming, singing and normal speech. As humming is nasalised sound, we have approached Mel filterbank-based ...
Phonetic segmentation: unsupervised approach
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
Phonetic segmentation can find its potential application for Automatic Speech Recognition (ASR) and Text-to-Speech (TTS) Synthesis systems. In this thesis, we propose use of different spectral features viz., Mel Frequency ...
RF power harvesting and enhancing throughput in a optical link based sensor network
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
Energy is one of the most important constraint inWireless Sensor Network (WSN), all the existing protocols, architectures revolve around the power plane. As the sensor network scale, their feasibility of implementation ...
RESTful web service integration
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
Internet is providing the platform for accessing different kinds of services in a distributed and heterogeneous environment. Software components are available on Internet in the form of Web Services. Service Oriented ...
SLAM (Self localization and mapping)
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
A fundamental competence of any mobile robot system is the ability to remain localized while operating in an environment. For unknown/partially known environments there is a need to combine localization with automatic ...
Studies on transcription, classification and detection of obstruents
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
Speech is the powerful mode of communication among the people. During the last few decades, there has been growing interest in speech related research all over the world. To develop algorithms for automatic speech recognition ...
Study of power in CR-SRAM in context of precharge reference voltage.
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
In Morden times power dissipation in electronic circuits has become more important due to increase use of portable and handheld devices. Increased operating frequency results in more power consumption in almost every VLSI ...
Text description of image
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
Image comprises of something which is easy for human beings to understand but difficult for a machine to interpret. In this thesis, we propose an algorithm to obtain the textual description of the image content. In order ...
Study on shock graphs: graph representation of objects
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
A shock graph is an abstraction of a two-dimensional shape of an object. It represents the shape as a graph, using its boundary information. In this thesis, we study the shock graph representation of two-dimensional shapes. ...
