 His assessment was based on a large sample of glossolalia recorded in public and private Christian meetings in Italy, the Netherlands, Jamaica, Canada, and the United States over the course of five years; his wide range of subjects included the Puerto Ricans of the Bronx, the snake handlers of the Appalachians and the spiritual Christians from Russia in Los Angeles ("Pryguny, Dukh-i-zhizniki").Samarin found that glossolalic speech does resemble human language in some respects.The speaker uses accent, rhythm, intonation and pauses to break up the speech into distinct units.
