What does the languages of whisper song at end mean from band evanescene?

The "languages of whisper song" in the Evanescence song "My Immortal" is a reference to the way the song's lyrics seem to be sung in a foreign language, even though they are actually in English. This effect is created by the use of a vocal technique called glossolalia, which is the spontaneous utterance of apparently unintelligible sounds. In the context of the song, the "languages of whisper song" can be interpreted as a representation of the protagonist's overwhelming emotions and her inability to express them in a conventional way. The lyrics suggest that she is so consumed by her grief that she is no longer able to communicate in a rational manner, and instead resorts to a primal, guttural expression of her pain.
