Voice recognition includes two basic parts: speech and speaker recognition. These
recognition processes consider as the most important processes of modern technologies,
many systems has been developed that differ in the methods used to extract feat
ures and
classification ways to support recognition systems of this type.
The study was conducted in this research on the previous subject, where the system
is designed to recognize the speaker and his voice orders and focus on several
complementary algorithms to carry out the research. we conducted an analytical study on
MFCC algorithm used in the extraction of features, and it has been studying two
parameters the number of filters in the filters bank and the number of features that taken
from each frame and the impact of these two parameters in the recognition rate and the
relationship of these two parameters on each other. It was the use of feed forwarding back
propagation neural networks performance analysis as characteristics and we analyze the
performance of the network to gain access to the best features and components to the
process of achieving recognition. And it has been studying Endpoint algorithm that used
to remove periods of silence and its impact on voice recognition rates.
The research presents is an attempt to study the Techniques and tactics of speech
which convince the receiver of its notions and ideas so that he takes them for granted then
it applies them to a historical text which is "the speech of Abullah Ibn Y
ehia, Head of
Ibadyyeh when ruling Yemen". the research also attempts to make a compromise clarifying
both sides of the saying : the theoretical and the practical alongside the tacticse utilized in
persuasion.
The orator\ speaker begins with emotional usages emanated from tribal thoughts that
both the receiver and the sender embrace taking them from Islamic law principles which
evoke fear in the Muslim receiver as they are ready-made arguments. Then they display
emotional mental ones that refrain from grabbing the attention of the receiver but make
him aware of the disappearance of classes' differences with the sender. This happens in
instructional strategies that enabled him to have an impact upon the receiver knowing his
intentions and aim via some data of pragmatic linguistics which rely on argumentation,
verbal acts and subtle expressionistic styles deployed in this same context.
This pragmatic might be the best when it comes to studying his speech, analyzing it,
then unraveling its tools of persuasion taking into account that is a science that studies
language in context.
