Title: Audio needs improvement
Review: Like another reviewer said, teaching tones needs more attention and practice, especially in contrasting them. I am not complaining about the audio amount in the main text but it would be advisable to have it clearer, slower and with pauses between phrases, even if Vietnamese people speak faster naturally. Alternatively, recording in 2 speeds could be provided - slow and natural. Individual vocabulary words could be read as well. As for the text, vocabulary choice and exercises, they are not bad and manageable, not always spoon-fed but the words can be found in the provided glossary. For any serious learner, a dictionary is a must, so... I give it 4 points for some flaws with audio. Perhaps, having Southern accent example would be good but this may only confuse some learners, taking into account the difficulty of the accent.
