I can't hear any of the tones!
A ạ á à ả sound all the same to me. Only in a select few sentences do I hear some distinctive intonation in à and á, but e.g. between i and ì and í there's no audible difference I can detect. It's only the length that I can differentiate. How can I improve my feel of the tones?
And then uô iê sound like long u i to me. I feel like I need to spend many weeks on my listening alone.
Did you try the exercise that is at the bottom of the post?
"To help with learning the tones, it might help to pair each tone with an action, to further burn it into your memory. Here are ones I have use for association:
Ngang (a) – hands moving forward, just below eye level
Huyền (à) – hands pushing down, starting from chest level
Hỏi (ả) – dipping motion with either hand
Ngã (ã) – forearms at shoulder level and rising, with a deliberate stop midway
Sắc (á) – hands lifting up, starting from just below chest level
Nặng (ạ) – dropping an (imaginary) stone from stomach level"
I learned a lot about tones and other pronunciations from these videos. Tones is the 4th video. :)
I actually find Vietnamese tones pretty easy to tell apart on the Duolingo audio, but I could already speak Mandarin, so I'm used to hearing tones (even though Mandarin tones are a bit easier, as stated in another comment). If you don't have that background, it's probably a bit harder.
Personally - I think the easiest Viet tone to recognise is the low-short (glottalised) one, the one with the underdot (ạ). It's short, sharp and forceful.
The tilde tone (ã) is also pretty distinctive, as it has a croak in the middle.
The hardest for me to tell apart are the low tone (à) and the hook tone (ả).
Duolingo has its limitations - as great as it is, it can only really be part of your language learning routine. I strongly recommend getting the Pimsleur course as an adjunct, even if just to get the sound system solid in your head.
with babies,when they practice speaking, they usually speak alone words ,those words are very easy to pronounce, like 'bố' (father) or ''mẹ'' (mother) ; ''bà ''(grandmothers), so ìf you want to improve your feeling òf the tones you should start at easy tones to you. my idea, you should pratice listening and pronouncing tone 'sắc' and ''huyền''
