Dear Kwiziq,
In virtually all of the dictations I have completed, I have found that it is quite difficult to discern when a sentence ends based on the speakers voice. This is to say, the speaker lowers his/her voice in a way that implies the end of a sentence, but when the answer is shown it becomes apparent to me that the lowering of the speaker's voice was actually meant to convey a pause. Is this the natural way hispanohablantes speak --- whether from Spain or Central/South America? Of course, as recommended, I do listen to the dictation before attempting to write it out, but I cannot memorize where sentences end vs. when there is a pause in the speaker's speech. Consequently, I'm constantly guessing at when the sentence ends. I am a native English speaker and typically, when translating spoken English to written form, lowering of the voice signifies a period --- not a pause (comma). As such, I often find it confusing (indeed, quite frustrating) to differentiate pauses from ends of sentences in the Kwiziq dictation exercises.
