Implementation of speech recognizer and synthesizer for the physically challenged
Speech Recognition and Speech Synthesis are two complementary technologies that are used in systems to which the human voice serves as input or output. People with physical, motor disabilities prefer systems that can be driven by their voice than using the strenuous, usual and standard input-output devices such as keyboard, mouse and monitor. Solutions under the umbrella of Assistive Technology are designed to support people with disabilities to overcome the difficulties in handling their diurnal chores. Present-day commercial speech processing systems have received wider customer acceptance, yet not suitable for people with speech disabilities. It is observed that present-day speech recognizers fail to recognize voices with distortions, misrepresentations and deformations. The unintelligibility of the input voice limits the use of off-the-shelf speech processing products by the speech-impaired user community. In such scenarios, the speech processing systems require alterations to become suitable for the specialised user group. Techniques of adaptation are popular in the field of speaker recognition, which can be applied in the domain of Augmentative and Alternative Communication (AAC). The main aim of this research is to model a speaker adaptive system for the speech-disabled users with articulation disorders and neurologically-based disorders due to illnesses like cerebral palsy. The problem context for this research work is two-fold: accepting the incomprehensible speech input and transforming the same into a more understandable speech. The first portion is to adapt a speech recognizer and verify the recognition accuracy; the second portion is to substitute the recognized words with a better- comprehensible voice. Due to the medical requirements of the research subjects, collecting and using live speech data of individuals is an onerous task with complex infrastructure. Also, the collection and storage of patients data are restricted by ethical procedures. Hence, the data created by various Universities, following the standard procedures in a noise-free environment are used for this research work. Experiments are conducted on the voice data sets in order to improve the recognition accuracy for speakers uttering individual words. The Speech Recognizer is implemented using Hidden Markov Models and Speech Synthesizer is implemented using a pattern-searching algorithm on a database with text input and voice output (concatenative synthesis). The adaptation techniques, viz., Maximum Likelihood Linear Regression (MLLR) and Maximum A Posteriori (MAP) are applied in a pipeline with adjusted language model and pronunciation dictionary. This has reduced the Word Error Rates (WER) of recognizing the incoherent speech. In the process of adaptation, the parameters of the acoustic model of a generic speech recognizer are altered using the feature vectors generated from the training data set applying maximum likelihood linear regression. Parameters of this updated model are then used as informative priors to MAP adaptation. Speech Synthesizer, i.e., the Text-to-Speech system then translates the recognized text into a more-intelligible voice which is clearer to the listeners. The simulation with test data sets measured the effectiveness of the combined algorithm proposed here; it produced improvements in recognition accuracy from 43% (for a speaker with 93% speech intelligibility) to 90% (for a speaker with 2% speech intelligibility). An analysis of the improvement in recognition accuracy and speed of recognition for each speaker reveals that the proposed methodology is more effective for severely dysarthric speakers than those with less speech impairments, making the proposed model socially significant. -

Investigations on plasma sprayed Yttria stabilized zirconia thermal barrier coatings on Al-11si
6-8% Yttria Stabilized Zirconia, (Y2O3-ZrO2), typically known as 8YPSZ, Thermal Barrier Coatings (TBCs) when applied via Electron Beam Physical Vapor Deposition (EBPVD) finds wide application in aerospace engineering. TBCs, applied on aero turbine super-alloy blades protect them from the high operating temperature environment and permit reduction in the required amount of cooling air, thereby improve engine performance and efficiency / component life. Likewise, 8YPSZ TBCs are widely used in larger components of the power generation turbines as well. In addition to aerospace, TBCs also find applications in automobiles and many other newlineengineering fields where high temperature and protection to metals is involved. Though a good amount of published literature is available on the 8YPSZ TBCs on super alloys (high temperatures alloys used in jet newlineengines), the same on TBCs on Al-11Si alloys (frequently used in automotive components) is very limited; even though the potential of this alloy in the automobile industry is enormous.In this research work, results from thermal barrier coating qualifications on a popular aluminium based alloy used in the automobile industry (removed from diesel engine piston), i.e. aluminium-11% silicon newline(Al-11Si) alloy is presented. Detailed coating qualification tests were performed on the Al-11Si alloy substrates with the 8YPSZ TBCs on them which comprised of material assessments at room temperature and higher newlinetemperatures. The performance of an actual multi (four) cylinder diesel engine incorporated with TBC coated pistons also was evaluated and compared with the performance of the baseline engine (without any coated newlinecomponents). Thus, the concept of Low Heat Rejection (LHR) engine was also assessed in this research work. Commercial plasma sprayable powders of 8YPSZ (METCO 204NS, newlineUSA) were plasma spray coated (TBC deposition) by employing an Atmospheric Plasma Spray (APS) system on substrates previously coated with Nickel Aluminide (NiAl) (AMDRY 956) plasma sprayable bond coat newlinepowders. -

Financial Capability and Decision Making Effects on Financial Wellbeing of Women in Community Based Organisations
Financial Social Work (FSW) is a multi-disciplinary interactive approach that deals with financially vulnerable populations financial issues/solutions. FSW deals with individual, family and community wellbeing by increasing access to good financial services, asset-building opportunities, financial education and guidance. The two concepts newlineunderlying FSW are financial capability and financial wellbeing. Financial capability is increasingly becoming a priority for policymakers, social workers, academicians and organisations of economic and social newlinesignificance. In India, limited studies are available for measuring the financial capability of Indian citizens. While literature suggests various studies on financial capability and financial wellbeing, the focus on their combined effect has been limited. The feminisation of poverty is an newlineessential topic when discussing the capability and wellbeing of women. This refers to the increasing tendency for those in poverty to be women and children due to the reasons such as economic conditions, demographic composition and government policy. Hence, it is relevant to consider newlinewomen as the focus point of the study. The present study measures women s financial capability and examines how demographic factors influence the same. The study also explores the impact of financial capability on the decision making ability and financial wellbeing of women associated with Community Based Organisations (CBOs). It further newlineexamines whether the decision making ability mediates between financial capability and financial wellbeing. Primary data was collected from the respondents through a structured questionnaire to identify and establish these aspects. In total, 1000 women who were associated with the CBOKudumbashree in the state of Kerala, India, identified through the multistage sampling technique, participated in the survey-based study. -

Effect of radiative transfer on Rayleigh-Benard convection in a couple- stress fluid
The problem of Rayleigh-Benard convection in a couple-stress fluid with thermal radiation is studied within the framework of linear stability analysis. Only infinitesimal disturbances are considered. The linear stability analysis is based on the normal mode technique. The fluid between the boundaries absorbs and emits thermal radiation. The boundaries are treated as black bodies. The absorption coefficient of the fluid is assumed to be the same at all wavelengths and to be independent of the physical state. The principle of exchange of stabilities is valid and the existence of oscillatory instability is ruled out. The expression for the stationary Rayleigh number is obtained as a function of the governing parameters, viz., the wave number, the couple-stress parameter, the conduction-radiation parameter and the absorptivity parameter. The Galerkin method is used to determine the eigenvalues. The effect of various parameters on the stability of the fluid layer is discussed through figures and tables.
