Is it hereditary that the front and back sounds of the tongue tip are unclear?

Unclear pronunciation of the front and back sounds by the tip of the tongue will have a great impact on our pronunciation. In particular, many people's pronunciation is not clear and they are unable to recite or do some other professions. This is also caused by problems with the tip of the tongue. The solution to the problem first comes from oral training. This disease has nothing to do with genetics.

introduce

The tip-of-the-tongue consonants are consonants produced by using the tip of the tongue to press against the back of the upper front teeth. The back of the upper incisors is located closer to the lips than the upper alveola, so compared to the tip-of-the-tongue middle sounds that use the tip of the tongue to press against the upper alveola, this type of sound is called tip-front sounds.

Pronunciation method

When pronouncing "z", the tip of the tongue presses against the back of the upper front teeth, the soft palate rises, and the airflow accumulates because the passage is completely closed. Then the tip of the tongue slightly leaves the back of the upper teeth, forming a narrow gap, and the air flows out from the narrow gap, making a sound due to friction. The vocal cords do not vibrate. The obstruction point and pronunciation method of pronouncing c are the same as those of pronouncing z, except that when pronouncing c, the airflow is much stronger than that when pronouncing z. z is a front-alveolar unaspirated voiceless affricate, and c is a front-alveolar aspirated voiceless affricate.

When pronouncing "s", the tip of the tongue approaches the back of the upper front teeth, forming a narrow gap. The soft palate rises, and the air flows out from the narrow gap, creating a friction sound. The vocal cords do not vibrate. s is a voiceless front-alveolar fricative.

Because when pronouncing the tip of the tongue, the tip of the tongue needs to extend forward, the upward posture is not obvious, and the tongue surface is straight, the tip of the tongue sounds z, c, s are usually called flat tongue sounds. In many dialects, retroflex and flat tongue sounds are not distinguished, and even these two types of sounds and the front tongue sounds j, q, x are not distinguished. When learning Mandarin, pay special attention to the distinction between these three types of sounds.

Pronunciation Tips

This is a group of sounds that are blocked by the tip of the tongue and the upper or lower incisors. When pronouncing, you should pay attention to the tip of the tongue must be focused and strong, and the contact area with the upper or lower incisors should be as small as possible, forming a point rather than a piece. Otherwise, the power of the pronunciation part will not be concentrated, making the pronunciation appear turbid and unclean.
