Felicitas Goodman studied a number of Pentecostal communities in the United States, the Caribbean, and Mexico; these included English-, Spanish- and Mayan-speaking groups. She compared what she found with recordings of non-Christian rituals from Africa, Borneo, Indonesia and Japan. She took into account both the segmental structure (such as sounds, syllables, phrases) and the supra-segmental elements (rhythm, accent, intonation) and concluded that there was no distinction between what was practised by the Pentecostal Protestants and the followers of other religions.[19]
