This document presents a voice recognition security system project. The project uses speech recognition to allow a user to control their Android phone through voice commands even if their hands are unavailable. It aims to keep users safe by recognizing their voice and taking actions. Key features include emergency calling, real-time location sharing, camera snapshots, and low data usage. The project is developed using Python, Kivy framework, OpenCV, and speech recognition libraries. It analyzes voice commands using hidden Markov models and accesses the microphone via PyAudio.
This document describes a voice recognition security system implemented using MATLAB. It discusses using voice recognition to authenticate users and secure personal information. The objectives are to construct a voice recognition system using MATLAB by understanding background math concepts, designing logical and hardware structures, and programming filters. The system works by sampling voice at 8000 Hz, applying digital filters to extract fingerprints, and comparing fingerprints to recognize words as passwords with 80-90% accuracy when choosing from 5 words.
Digital watermarking is a technique for hiding copyright information in digital content such as images, audio and video. A digital watermark is imperceptibly embedded in the digital content and can be extracted or detected to prove ownership. There are two main types of watermarks - visible watermarks that can be seen and invisible watermarks that cannot be seen by the human eye. Watermarking techniques include spatial domain and frequency domain methods. The Fast Hadamard Transform is commonly used for digital image watermarking as it allows for faster processing times and robust watermarks. The watermarking process involves embedding, attacks on the watermarked content, and detection of the watermark.
Voice morphing is a technique that modifies a source speaker's speech to sound like a target speaker. It does this by changing the pitch from the source speaker, like a male voice, to the target speaker, like a female voice. This is done by interpolating the linear predictive coding coefficients of the source and target signals. The pitch of the morphed signal can be positioned between the source and target by varying a constant value between 0 and 1. Applications include changing voices for security or entertainment purposes, but limitations include difficulties with voice detection and requiring extensive sound libraries.

Automatic speech recognition allows for verbal human-machine interaction by using computer systems that can understand and respond to human speech in natural language. It simplifies tasks by allowing users to control devices with voice commands instead of physical input. While speech recognition helps with computer tasks and assists disabled people, it still faces challenges with background noise, different accents, voice changes, and spontaneous speech.
It is a technique to modify a source speaker's speech to sound as if it was spoken by a target speaker.
Voice morphing enables speech patterns to be cloned

Speech recognition, also known as automatic speech recognition or computer speech recognition, allows computers to understand human voice. It has various applications such as dictation, system control/navigation, and commercial/industrial uses. The process involves converting analog audio of speech into digital format, then using acoustic and language models to analyze the speech and output text. There are two main types: speaker-dependent which requires training a model for each user, and speaker-independent which can recognize any voice without training. Accuracy is improving over time as technology advances.

ABSTRACT
Cloud computing promises to significantly change the way we use computers and access and store our personal and business information. With these new computing and communications paradigms arise new data security challenges. Existing data protection mechanisms such as encryption have failed in preventing data theft attacks, especially those perpetrated by an insider to the cloud provider. For securing user data from such attacks a new paradigm called fog computing can be used. Fog Computing is a paradigm that extends Cloud computing and services to the edge of the network. Similar to Cloud, Fog provides data, compute, storage, and application services to end-users. The motivation of Fog computing lies in a series of real scenarios, such as Smart Grid, smart traffic lights in vehicular networks and software defined network .This technique can monitor the user activity to identify the legitimacy and prevent from any unauthorized user access. Here we have discussed this paradigm for preventing misuse of user data and securing information.

Paper Title
Particle Swarm Optimization–Long Short-Term Memory based Channel Estimation with Hybrid Beam Forming Power Transfer in WSN-IoT Applications
Authors
Reginald Jude Sixtus J and Tamilarasi Muthu, Puducherry Technological University, India
Abstract
Non-Orthogonal Multiple Access (NOMA) helps to overcome various difficulties in future technology wireless communications. NOMA, when utilized with millimeter wave multiple-input multiple-output (MIMO) systems, channel estimation becomes extremely difficult. For reaping the benefits of the NOMA and mm-Wave combination, effective channel estimation is required. In this paper, we propose an enhanced particle swarm optimization based long short-term memory estimator network (PSOLSTMEstNet), which is a neural network model that can be employed to forecast the bandwidth required in the mm-Wave MIMO network. The prime advantage of the LSTM is that it has the capability of dynamically adapting to the functioning pattern of fluctuating channel state. The LSTM stage with adaptive coding and modulation enhances the BER.PSO algorithm is employed to optimize input weights of LSTM network. The modified algorithm splits the power by channel condition of every single user. Participants will be first sorted into distinct groups depending upon respective channel conditions, using a hybrid beamforming approach. The network characteristics are fine-estimated using PSO-LSTMEstNet after a rough approximation of channels parameters derived from the received data.
Keywords
Signal to Noise Ratio (SNR), Bit Error Rate (BER), mm-Wave, MIMO, NOMA, deep learning, optimization.

9. Python is a general-purpose a high level, interpreted , object-
oriented, dynamically typed programming language that is often
applied in scripting roles.
So, python is programing language as well as scripting
language.
Python is also called as interpreted language .
Python useful for complex application development as it is for
scripting or "glue code" that connects components together.
Python is a universal language found in a variety of different
applications
10. WHAT IS KIVY
• Kivy is a free and open source Python framework for developing
mobile apps and other multitouch application software with a
natural user interface (NUI). It is distributed under the terms of
the MIT License, and can run on Android, iOS, GNU/Linux,
macOS, and Windows.
• Kivy was first released in early 2011. This cross-platform
Python framework can be deployed to Windows, Mac, Linux,
and Raspberry Pi. It supports multitouch events in addition to
regular keyboard and mouse inputs. Kivy even supports GPU
acceleration of its graphics, since they’re built using OpenGL
ES2. The project uses the MIT license, so you can use this
library for free and commercial software.
11. WORKING WITH KIVY WIDGETS
• A widget is an onscreen control that the user will interact with. All
graphical user interface toolkits come with a set of widgets. Some
common widgets that you may have used include buttons, combo
boxes, and tabs. Kivy has many widgets built into its framework
• When you create an application with Kivy, you’re creating a Natural
User Interface or NUI. The idea behind a Natural User Interface is that
the user can easily learn how to use your software with little to no
instruction.
• Kivy does not attempt to use native controls or widgets. All of its
widgets are custom-drawn. This means that Kivy applications will
look the same across all platforms. However, it also means that your
app’s look and feel will differ from your user’s native applications.
This could be a benefit or a drawback, depending on your audience.
12. Running a “Hello, Kivy!” Program
To see how Kivy works, take a look at the following “Hello, World!” application:
from kivy.app import App
from kivy.uix.label import Label
class MainApp(App):
def build(self):
label = Label(text='Hello from Kivy',
size_hint=(.5, .5),
pos_hint={'center_x': .5, 'center_y': .5})
return label
if __name__ == '__main__':
app = MainApp()
app.run()
13. SPEECH RECOGNITION WITH PYTHON
Most modern speech recognition systems rely on what is known as a Hidden
Markov Model (HMM).This approach works on the assumption that a speech
signal, when viewed on a short enough timescale (say, ten milliseconds), can
be reasonably approximated as a stationary process—that is, a process in
which statistical properties do not change over time.
Working With Microphones
• To access your microphone with Speech Recognizer, you’ll have to install
the PyAudio package.
14. PICKING A PYTHON SPEECH RECOGNITION
PACKAGE
A handful of packages for speech recognition exist on PyPI. A few of
them include:
• apiai
• assemblyai
• google-cloud-speech
• pocketsphinx
• SpeechRecognition
• watson-developer-cloud
• wit

• This project is going to be developed in future and in future we
can use a ai to understand the voice of a user and also the ai
can see the user with help of a user it will make the much safe
for a person and is AI can see the user or hear him it can guess
the what action his user do is user try to suicide then it send
the info to nearest person and save its user . These can be
become the future of this project
18. CONCLUSION
• The voice recognition system is the capacity of a device or
program to receive and understand dictation, or to understand
a spoken instruction. The main concept of this project is to
design a voice recognition security system. This project is
mainly used for security purpose to identify the voice spoken
from the authorized person and the system work according to
its instruction
• Personal security is a general condition that occurs after
adequate ef.forts are taken to deter, delay, and provide warning
before possible crime.
