best method of opening the airway of an unresponsive victim when you do not suspect cervical spine injury
The first method of opening the airway of an unresponsive victim, when cervical spine injury is not suspected, is the head-tilt, chin-lift maneuver. This technique involves tilting the head back slightly by placing one hand on the victim's forehead and using the fingers of the other hand to lift the chin forward. This position helps to clear the airway by moving the tongue away from the back of the throat, allowing for better airflow. Always ensure to check for breathing after performing this maneuver.
(The nasopharyngeal airway device is another method to insure the airway is open.) Grasp the angles of the victim's lower jaw and lift with both hands, one on each side, displacing the jaw forward and up. Your elbows should rest on the surface where the victim is lying. If the lips close, the lower lip can be opened with your thumb. If mouth-to-mouth is necessary, close the nostrils by placing your cheek against them. The victims head should be carefully supported without tilting it backwards or turning it from side to side. If this is unsuccessful, the head should be tilted back very slightly. The jaw-thrust is the safest approach to opening the airway of a victim who has a possible neck injury because it can be accomplished without extending the neck.

Rest your elbows on the same surface in which the victim is lying.The naso-pharyngeal airway device is another way to insure the airway is open.

Place elbows on the same ground as the victim's head.
A nasopharyngeal airway is used when you don't want to intubate the victim. Sometimes all you need is that open airway.
What is your question?
The victim would be unable to speak, or sing opera.
