When I read this sentence, my first impulse was to look up photographs of a Sámi shaman:
It's interesting that the TTS pronounces shamaani (šamaani) with [s] as a single word, but with [ʃ] in the sentence.
Indeed. But which pronounce is correct?
How is it possible to write the correct version of Sami?

What is a shaman and sami?
Let me google that for you:
