“Voice Recognition Control in Security Surveillance System”
Voice or Speech Recognition technology promises to change the way we interact with machines (robots, computers etc.) in the future. This technology is getting matured day by day and scientists are still working hard to overcome the remaining limitation.
Speech recognition is the process of converting an acoustic signal, captured by micro- phone or a telephone, to a set of words . There two important part of in Speech
Recognition
- i) Recognize the series of sound and
ii) Identified the word from the sound.
This recognition technique depends also on many parameters - Speaking Mode,
Speaking Style, Speaker Enrollment, Size of the Vocabulary, Language Model, Perplexity, Transducer etc.
There are two types of Speak Mode for speech recognition system
- one word at a time (isolated-word speech) and continuous speech. Depending on the
speaker enrolment, the speech recognition system can also divide - Speaker dependent and Speaker independent system. In Speaker dependent systems user need to be train the systems before using them, on the other hand Speaker independent system can identify any speaker’s speech. Vocabulary size and the language model also important factors in a Speech recognition system. Language model or artificial grammars are used to confine word combination in a series of word or sound. The size of the vocabulary also should be in a suitable number. Large numbers of vocabularies or many similarsounding words make recognition difficult for the system.
The most popular and dominated technique in last two decade is Hidden MarkovModels. There are other techniques also use for SR system - Artificial Neural Network (ANN), Back Propagation Algorithm (BPA), Fast Fourier Transform (FFT), Learn Vector Quantization(LVQ), Neural Network (NN) [7].
GUIDELINES OF PROJECT PLANNING:
Project Objectives
This section describes the measurable objectives of the project and defines the expected results
Project Background
The Project Background should cover the following elements:
1. The major issues and problems to be addressed by the FYP.
2. FYP Research necessity and importance.
3. Variables and parameters of the research.
4. Hypothesis or theory, if any.
5. Setting the limits or boundaries of the proposed FYP in order to provide a clear focus.
The literature review should be addressed in this section to meet the requirements below:
1. Demonstrates knowledge of the research problem.
2. Demonstrates understanding of the theoretical and research issues related to the FYP question.
3. Critically analyses, integrates and synthesises the relevant literature information
Project Methodology
The FYP methodology demonstrates how the student plans to tackle the FYP problem. It should have details of the analytical techniques, project design and description of research activities. Specialised equipment, facilities and infrastructure, whether new or existing, required for the project, should also be identified at this stage.
The student should compare the methodology with alternative methods and justify that the approach chosen is the most appropriate.
Project Activities
It will provide the work plan and the list of the activities necessary for the project, including those associated with the transfer of the FYP results to customers / beneficiaries. It should also outline the sequence of the proposed activities and identify them in numbered stages, steps or phases. The FYP activities as well as the timing and duration will be reflected in the Gantt chart.
Milestones
A milestone is achieved when a significant phase in the project is reached, for example completion of testing, commissioning of equipment, etc. There must be at least 2 milestones per individual semester. The first milestone at the start of the project is optional while the last milestone denotes the end / completion of the project.
The timing of the milestones will be reflected in the Gantt chart.
Expected Outcome:
The output expected varies amongst the different types of FYP undertaken. For our UniKL MFI FYP, use the following list of outputs:
- Method / technique
- Demonstrator / prototype
- New / improvement in terms of product / device, Process, software, material, service, IPR
