Perception Of Speech

Decotra - The perception of speech is not an easy thing done by the humans because speech is a verbal activity that glide with no clear timeline between one word with another word. Note the following three utterances: (a) not a number, (b) Open jackfruit, and (c) Not jackfruit. Though this speech three meanings differed from one another, the pronunciation is the third form of speech may be the same -. 

In addition, a sound is also not pronounced exactly the same sound every time it appears. How a spoken sound is influenced by the environment in which the sound is. Sound [b] the words of hunting, for example, is not exactly the same as the sound [b] in the word blue. In the words of Rush sound / b / is affected by the sound / u / is followed so that there is a little more lip rounding elements in making this sound. Conversely, these same sounds will be pronounced with a wide lip on the blue words to the sound / i / is a front vowel sound with wide lips.However, humans are still able to perceive the sounds of the language well. Of course, such a perception is done through certain stages. Basically there are three stages in the processing of sound perception (Clark & ​​Clark, 1977): 

1. Auditory Phase: In this phase people receive speech piece by piece. Speech is then addressed in terms of acoustic features. Concepts such as points of articulation, manner of articulation, distinctive features, and VOT is very useful here because of happenings like this that separate one sound from another sound. The sounds in the speech that we keep in our auditory memory.2. Phase phonetics: The sounds that then we identify. In our mental processes, we see, for example, whether the sound is [+ consonantal], [+ vois], [+ nasal], and so on. Similarly, the sound environment: whether the sound was followed by a vowel or by a consonant. If by vocal, vocal kind of what - front vowels, back vowels, high vowels, low vowels, etc.. Speech if it is not jackfruit, then we analyze the mental sound / b / first and determine what sound we heard was to pay attention to things like points of articulation, manner of articulation, and distinctive features. Then VOT is also noted as VOT is what will determine when the vibration of the vocal cords that happen. 

The sound segments then we store in phonetic memory. The difference between auditory memory with phonetic memory is the memory is audi-tori all allophonic variations that exist in the sound while we save on memory only phonetic features that are phonemic only. For example, when we heard a [b] of the word blind that we save on auditory memory instead of phonemes / b / and not just a point of articulation, manner of articulation, and features his distinctive, but also influence the sound / u / that follow. Thus, the [b] This was followed by a somewhat roundabout lips (lip-rounding). On phonetic memory, things like this are no longer needed his deep sound that we perceive as sound / b / then the details are not significant anymore. Does that mean, if / b / is followed by a roundabout lips or not, still the sound is the sound / b /. 

Another mental analysis is to see how it sounds caused sorted sequence is what will determine the sound of the words saying what. Sound / a /, / k /, and / n / may form dif-ferent words when the order differed. When / k / heard it first, then / a / and / n / it will sound lo / right /; when / n / is earlier, then there came the sound / son /.
