Since neither the "—" in the written form, nor the change in voice in the spoken form are part of the Lojban text, where is the mismatch? They are both extratextual enhancements to aid in comprehension. If you plan to read it in a monotone voice it will be hard to follow, but it would also be hard to follow for a reader if the text was written without any spaces and line-breaks.You could also read the "—" as "ni'o" or some new member of NIhO that meant "new speaker", in which case the "—" would become part of the text.mu'o mi'e xorxes
