Glossolalia.


observed properties

intonation seems same as speaker's native language.

most common vowels - [i] and [a]

common consonant? - [sh]

much smaller phoneme inventory than most (and native) languages.

lots of repetition.

use of "exotic sounds" that are known (consciously or not) to speaker - eg. changing bunched [r] to tap [r].



xenoglossa?

apparently no concrete evidence. testimonials are available, but they are often by people likely with a bias.



of god/of the devil?

glossolalia not limited to christianity. present in voodoo and other parts of the world. sounds are similar?
