The voiced dental fricative is a consonant sound used in some spoken languages.It is familiar to English-speakers as the th sound in father.Its symbol in the International Phonetic Alphabet is eth, or ð and was taken from the Old English and Icelandic letter eth, which could stand for either a voiced or unvoiced (inter)dental non-sibilant fricative.
The following are the non-pulmonic consonants.They are sounds whose airflow is not dependent on the lungs. These include clicks (found in the Khoisan languages and some neighboring Bantu languages of Africa), implosives (found in languages such as Sindhi, Hausa, Swahili and Vietnamese), and ejectives (found in many Amerindian and Caucasian languages).

In standard English, the phonetic realization of the two dental fricative phonemes shows less variation than many other English consonants. Both are pronounced either interdentally, with the blade of the tongue resting against the lower part of the back of the upper teeth and the tip protruding slightly, or with the tip of the tongue against the back of the upper teeth.
There are several types (those used in English being written as th): Voiced dental fricative [ð] - as in the English this, [ðɪs]. [2] Voiceless dental fricative [θ] - as in the English thin, [θɪn]. [2] Dental ejective fricative [θʼ]
The voiced alveolar lateral fricative is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents voiced dental , alveolar , and postalveolar lateral fricatives is ɮ (sometimes referred to as lezh ), and the equivalent X-SAMPA symbol is K\ .
Most commonly, the change is a result of sound assimilation with an adjacent sound of opposite voicing, but it can also occur word-finally or in contact with a specific vowel. For example, the English suffix -s is pronounced [s] when it follows a voiceless phoneme (cats), and [z] when it follows a voiced phoneme (dogs). [1]
