How do I pronounce 用勿着 in Shanghainese?
Here is the entry for 用勿着 in《上海方言词典》on p. 304:



Text:

【用勿着】
ɦyoŋ˨˧꜖ uə?˥꜒ za?˨˧꜒꜔
⇨ ⟦得⟧ ßiɔ˥꜒ tə?˥꜒꜕

Tone letter to number translation:

ɦyoŋ²³⁻¹¹ uə?⁵⁵⁻⁵⁵ za?²³⁻⁵³

Tone sandhi is usually represented by back-to-back tone letters. So it looks like the corrected tones are:

ɦyoŋ¹¹ uə?⁵⁵ za?⁵³

Correct me if I'm wrong, because I have no idea about Shanghainese tones.

Here's an entry from a second dictionary 上海话大辞典 p. 274
