Quite often in children it causes difficulty understanding and memorizing the vowels and consonants, and voiced and unvoiced sounds. Therefore, in addition to other tasks in the program "Primerchik" added a very simple but very useful task for the study of vowels and consonants. Shows children the task list of Russian letters and the child must arm highlight all occurrences of vowels or consonants. You can also configure the task to test the knowledge of consonants deaf and voiced consonants letters.
In Russian, 10 vowels (a, y, a, s, and, uh, I, w, e, f) and 21 of the letter (b, c, d, e, g, h, k, k, l, m, n, p, r, s, t, f, x, y, h, w, u).
Voiced letters are as follows: b, c, d, e, g, h, k, l, m, n, p.
Deaf letters: k, n, s, t, f, x, y, h, w, u.
And we have ChildWebGuardian PRO
The program helps parents to solve two problems:
1. Limit the time spent with the child at the computer.
2. Block inappropriate sites and limit the social networks.
And do it all possible through the online parental control system!
And in the "Primerchik" but jobs vowels and consonants, voiced and unvoiced letters and many other primerchik: the multiplication table and the addition / subtraction of a column, and fractions and brackets, and more!
ANSWERS MAIL.RU: What is different vowel sounds from consonant?
Vowel sounds are called, are unlike the consonants occur in the formation of tone - without the noise. In addition, unlike the consonant vowels can form syllables and participate in the formation of stress. Vowel sounds in the Russian language is very important: in addition to participating in smyslorazlichenii, they are for us to support the determination of the rhythmic structure of speech and its limits.
In Russian vowels have the following functions: participate in the construction of words, can distinguish words, create a rhythm - to form an accent, to participate in shaping the tone (including emotional - "" How did she pla-avaet! "" - we say when we want express my particularly warm attitude). Vowel sounds in the Russian language the most intense and can change their length in a very wide range, unlike most consonants. Acoustically vowels from consonants differ significantly greater total energy of the utterance. This feature - the total energy of the utterance - is important not only for the vowels, it also allows you to distinguish among consonants special class sonorous sounds, or sonants. Sonants occupy an intermediate position on the basis of the total energy between pronouncing vowels and the rest of the (non-sonorous) consonants - explosive, noisy and affricates. Compare the words of maximum contrast in intensity between the consonants and vowels (deaf explosive consonant + vowel), and words with minimal contrast (these words are made up of vowels and sonants).
whale - pact - Cap - Dad - sieve
small - we - Laurel - my mother - the norm - the frame
The basis of vowel sounds - tone. The harmonic character of the tonal sound is important for speech - harmonic oscillations have a high energy level, as well as the fact that the sound energy is distributed fairly evenly across the acoustic spectrum, thus the sound becomes resistant to all sorts of natural noise, which in most cases are located in a limited spectral range . Therefore, the vowel sounds clearly audible, they can be stretched in duration (lost in the woods, we call "ay-oo-oo!"); they can be quite short, but at the same time retain their intensity. This property vowels allows for such a fundamental phonetic system of Russian language phonetic phenomena as quantitative reduction of vowels.
Vowel sounds in Russian language aurally vary depending on the size and shape of the resonators which are formed in the speech path by changing the position and shape tongue in the oral cavity, and also depending on how the shape of the mouth opening formed through the lips, changes the nature of the air jet at the outlet mouth. However, language, like most slider articulation, is always busy in manufacturing and other sounds - consonants (as well as the lips). Therefore, the volume and shape of the cavities in the speech flow is constantly changing due to coarticulation processes. And subsystems Russian vowels (as well as consonants) can not be set beyond their meaning-possibilities in a single phonetic system of language.
Vowels melodious, smooth, logkozvuchnye, freely come out of the mouth.
Consonants are created in the vocal apparatus (mouth, tongue) the sound barrier as if they stumble about all that is in the mouth (palate, teeth, tongue, gums, lips).
