It was inferred that with the combination of speech enhancing modules, speech recognition was more accurate. Surveying different concepts, it can be inferred that there is a need to bring up a real time speech therapy framework to help people with speech disorders. This paper deals with a human machine interface which provides real-time feedback to patients through an interactive speech therapy session. OVERVIEW OF THE PROPOSED SYSTEM Fig.1 shows the block diagram of the proposed system. The audio signal is obtained from the user and it is processed to extract the necessary values.
In the field of human language technologies and signal processing the speech or language processing is considered as an important technological area of research and development. In speech signal processing the speech recognition, processing and production of speech signal, speech quality assessment and speech coding or decoding are challenging field of research. Speech signal processing applications are major factor in human-machine interaction and offer many new and significant applications. The main research areas in this domain are speech recognition, speech quality assessment, speech synthesis and speech coding. The machine models are the mimic of human speech production system or human auditory system.
“The first one is known as the training phase while the second one is called as testing phase.”  In the training phase, each registered speaker has to provide samples of their speech so that the system can build a database of samples for that speaker. It consists of two main parts. In the first part each person’s input voice sample is processed to sum up the characteristics of their vocal tracts. The second part involves collecting each person's data together into a single, easily manipulated matrix. The testing system has the exact system architecture as the training system.
Those visual or auditory information is passed through the Wernicke’s area which is cerebral cortex. It relates to speech and identifies the spoken and written language. When Carl Wernicke’s, a neurologist found out that the area where words and syllables are pronounced, he named that area after his name as “Wernicke’s area”. After recognizing the visual or auditory message, it passes through the frontal lobe of the brain which is referred as Broca’s area where the production of the language or speech takes place. Likewise, the Wernicke’s area, the Broca’s area is named after a neurologist who found that a patients who had sustained a head injury to the region have difficulty in producing the speech.
Speaking is a process of how speaker constructs meaning which includes creating and receiving information on an interactive way (Brown, 1994). The meaning and the form are delivered to the hearer depending on the context which also includes the participants, physical environment, and purposes for the speaking. Speaking is used to show someone 's feelings, thoughts, and even ideas to other people (Herman, 2016). Speaking is also one of the most important skills which should be supported by some components such as grammar competence, vocabulary mastery, and good pronunciation (Ur, 1996). In speaking, one of the components that should be mastered is pronunciation.
The discourse analyst focuses on â€œan investigation of what that language is used forâ€, it means purpose and aim of communication, as has actually been mentioned before (Yule 1983: 1). Levels of analysis Crystal (1997: 15) mentions a few levels of analysis which are highly important for a detailed analysis of a text. Each level represents one area of linguistics such as lexicology or phonetics and phonology. On the basis of these areas different levels of analysis can be distinguished: phonetic and phonological, graphological, grammatical, lexical. Verdonk mentions importance of pragmatics and claims that â€œpragmatics is concerned with the meaning of language in discourse, that is, when it is used in an appropriate context to get particular aimsâ€ (Verdonk 2002:
In identification, the goal is to determine which voice in a known group of voices best matches the speaker. In speaker verification, the goal is to determine if the speaker is who he or she claims to be. The aim of the paper is to use Gaussian mixture speaker model (GMM) to optimize the performance of automatic speaker recognition by reducing the error rate (ERR) between the real claimant and imposter. 1.4 LIMITATION Many challenging problems and limitations remain to be overcome in recognizing speaker or to detect the true claimer from imposter. i.
- Vocal expression, the way the performer uses their voice to convey a character. Jo-Anne Bachorowski in Vocal Expression and Perception of Emotion states that “The expression of emotions in speech sounds and corresponding abilities to perceive such emotions are both fundamental aspects of human communication.” (1999) therefore, this element is an important aspect of the creation of the connection between the performer and the audience. - Inflection, Change in pitch or loudness of the voice. As the voice is a more permeable channel than the face, it is more challenging to control and therefore, is more likely to expose true feelings. The sound of one’s voice changes as the rate of vibrations changes.
Introduction Language and dialect are seen as terms that are ambiguous. One of the reasons may be because of the fact that language itself is a diverse term and can adopt different definitions depending on the context or set of institution. In this essay, language and dialect are defined, described and thoroughly discussed and concrete examples are provided to support the theory that is provided in this essay regarding language and dialect. A brief discussion regarding the origins of language and how it evolved is also taken into consideration. This essay also discusses the connection between language and dialect with an aim of unpacking their real meaning and makes these terms to be more understandable rather than ambiguous.
There are definitely many factors influencing individuals' estimation of communicative ability. That is, what makes a person to assess his own communication one way or another must be sought in some internal or external factors. The factors might be found in one dimension
