The goal of this clinical trial is to learn the effect of Speech-to-speech Voice-Cloning Care (SVCC) on improving ICU-acquired anxiety for critically ill patients. The main question it aims to answer is:
* Can the use of participants' loved ones' voices by nurses in communication while providing care lead to better mental health and clinical outcomes?
Researchers will see if the implementation of SVCC can reduce anxiety and depression and improve clinical outcomes.
Participants will:
* Receive the SVCC intervention until the endotracheal tube (ETT) is removed. * Keep a diary of delirium, the duration of mechanical ventilation, and ICU stays.
Expected mechanical ventilation time > 24 hours;
Expected ICU stay > 72 hours;
