Step 1: The question refers to the "Acceptance Speech" delivered by Alexander Aris on behalf of his mother, Aung San Suu Kyi.
Step 2: The speech was delivered upon receiving the Nobel Peace Prize, an award that brought global attention to the pro-democracy movement in Burma (Myanmar).
Step 3: Alexander Aris's speech implies that while the world is aware of the human rights violations and suffering in Burma (it has been 'heard'), not enough concrete action has been taken by the international community to alleviate it (it has been 'ignored'). The award is a significant step, but the larger problem of inaction remains.
