Video Examples of Baby-Toddler Noises, and Speech 24-60 Months

Vegetative Sounds

Vegetative sounds relate to bodily functions: digestion, excretion and respiration. The sounds include burps, coughs, hiccups, sneezes, gulps, grunts, etc.

Newborn: Typical development


Fixed signals

Fixed signals are recurring motor sequences that do not vary across individuals (or languages: a giggle will never sound as though the giggler speaks a particular language). Fixed signals include laughs, giggles, cries, and moans, etc.

8 months: Typical development


Protophones

The purpose of protophones varies. They can be "just for fun", to attract attention, etc. Protophones are speech-like, but not "transcribable"; that is, they cannot be written down using phonetic symbols (IPA | Extended IPA for transcribing disordered speech). Protophones include quasivowels (vowel-like sounds produced with the vocal tract at rest) and marginal babbling (sometimes called pre-canonical babbling). It is similar to cooing where the infant produces a few random sounds.

4 months: Typical development

12 months: Typical development


Resonant Productions

Fully resonant productions are "transcribable"; that is, they can be written down using phonetic symbols (IPA | Extended IPA for transcribing disordered speech). Resonant productions include fully resonant vowels, resonant consonants, canonical babbling and true words.

14 months: Typical development

Canonical Babbling: Typical development

Variegated Babbling: Typical development


Speech

"Speech" can include meaningful speech (real words) or non-words (made-up wordsž)

24 months made-up words: Typical development

30 months: Typical development

37 months: children talking to each other on the phone: Typical development

48 months: telling a story (1): Typical development

48 months: telling a story (2): Typical development

60 months: A 5-year-old asks Siri a series of questions: Typical development
