Sufficient cognitive ability to follow simple instructions via a mobile device (tablet)\n5. For children under 7 years of age: a caregiver who has received sufficient explanation of the study purpose and procedures and has voluntarily provided written informed consent\n6. For children aged 7 years or older: voluntary assent from the child after sufficient explanation of the study purpose and procedures by the investigator,\n\nin addition to written informed consent from the caregiver\n\nExclusion Criteria:\n\n1. Caregiver or child does not consent to study participation, or withdraws consent during the study\n2. U-TAP results indicate articulation development within the normal range, with no suspicion of articulation developmental delay\n3. Difficulty understanding simple instructions or participating in assessments and training due to moderate or severe cognitive impairment, attention deficit, autism spectrum disorder, or similar conditions\n4. Significantly limited speech production due to neuromuscular or anatomical causes, including severe visual impairment or visual field deficits, hearing impairment, cleft palate structural abnormalities, or severe oral\u002Ffacial muscle dysfunction, resulting in difficulty with articulation\n5. Inability to continue study participation due to acute illness or other conditions that may affect assessment or training during the study period, or unwillingness of the caregiver or child to continue participation\n6.
