Most often in the Russian language, one letter corresponds to one sound. For example, the word "table" with four letters and the same sounds. It is good it becomes clear to the children when they perform phonetic analysis of words or just make up his transcription.
A mismatch occurs if the letter "e", "I", "u" are the beginning of a word, after a vowel and after a hard or soft signs. In addition, they soften the standing in front of a consonant, they also form the two sounds. For example, the word "Apple" for the letter "I" stands for two sounds [ th ] and [ a ]. Thus, in the word of letters six, seven and sounds. And the word "Blizzard" is the letter "s" after the soft sign, represents two sounds: [ y ] and [ y ]. So the sounds in this word will be one greater than the number of letters.
Does not match the number of letters and sounds in words with silent letters. In him there will be more characters, as some will not be indicated with sounds. For example, the word "flattering" is unpronounceable consonant "t". It has no sound. So this word is seven letters and six sounds. And the word "heart", the letter "d" is silent. It has six letters and five sounds.
If you try to count the number of sounds in the verbs ending in "tsya" and "ll", you will see that they are less than letters. This is clearly seen in the transcription of speech. "Sterile" or "ll" in it are indicated the two sounds [TS ]. So, the word "learning" with six letters and five sounds.
Not marked with the sounds of hard and soft signs. For example, the word "fire" is five letters and only four sounds.
To learn how to count the number of sounds, you need to understand the basic rules of phonetics and master the sound analysis of words.
