Approximately equal numbers of phones are now produced in word-initial and intervocalic position. Additions to the phonetic inventory are the voiced stop /ɡ/ and a few consonant clusters. Co-articulations are perceived, such as labio-velar plosives and the aspirated plosive series. Alveolars and bilabials are the two most common places of articulation. Labiodental and postalveolar production increases throughout development, while velar production decreases. Luthic lenitions also become evident, as more fricatives and approximants are produced. Children develop syllabic segmentation awareness earlier than phonemic segmentation awareness. | Approximately equal numbers of phones are now produced in word-initial and intervocalic position.

=====Word processes===== | |||
* ''Weak syllable deletion:'' word-initial and word-terminal unstressed syllables are often omitted [bɐˈna.nɐ] > [ˈna.nɐ]; | |||
* ''Coda deletion:'' omission of general coda consonant and the final consonant in the word [kɐɾ] > [kɐ], [ˈbɾo.θɐɾ] > [ˈbɾo.θɐ]; | |||
* ''Consonant harmony:'' a target word consonant takes on features of another target word consonant , [kɐn] > [kɐŋ], [ˈstɛk.kɐ] > [ˈstɛt.tɐ]; | |||
* ''Velar fronting:'' velar plosives are often replaced by alveolar ones nearby a front vowel [ki] > [ti]; | |||
* ''Stopping or affrication:'' fricatives are often fortified nearby a front vowel [si] > [ti ~ t͡ʃi]; | |||
* ''Gliding:'' taps and liquids are replaced by a glide [ˈka.ɾu] > [ˈka.wu], [ˈaʎ.ʎo] > [ˈaj.jo]. | |||
=====6 years===== | |||
Children produce mostly adult-like segments. Their ability to produce complex sound sequences and multisyllabic words continues to improve throughout middle childhood. | |||
