Tongue Exercise for EFL AB04

This app is babble training to help student.

Developed a babble training app to help students understand the importance of prosody : rhythm, stress and intonation of speech.

Babbling is a stage in child development and a state in language acquisition, during which an infant appears to be experimenting with uttering articulate sounds, but does not yet produce any recognizable words. Babbling begins shortly after birth and progresses through several stages as the infant's repertoire expands and vocalizations become more speech-like. Infants begin to produce recognizable words usually when they are around 12 months of age, though babbling may continue for some time afterward. Babbling can be seen as a precursor to language development or simply as vocal experimentation. The physical structures involved in producing speech are developed in the first year of a child's life. Abnormal developments such as certain medical conditions, developmental delays, and hearing impairments may interfere with a child's ability to babble normally. Unlike language, babbling is not unique to the human species.

Babbling is a state in language acquisition. These vocalizations do not contain meaning or refer to anything specific. Human infants are not excited or upset when babbling, but instead they will babble spontaneously and incessantly only when they are emotionally calm.

The sounds and expressions of babbling are produced before an infant begins to construct recognizable words. This is mainly due to the immaturity of the vocal tract and neuro musculature at this age in life.
