One way to picture it: a tight string is pulled back and let go. The sound that follows is short, bright and a little sharp, and it shakes for a moment before it dies. The evidence packet says the word is simply that sound. From there, everything else is the same sharpness moved somewhere new — into a voice, or onto the tongue.
The evidence packet marks the word as onomatopoeic — it imitates the sound itself — and compares older words in the twinge family. It offers no further route to the voice or taste uses, so those links are read here as pictures, not as descent.
手上的資料把這個字標成擬聲：字的聲音就是那個聲音，並拿 twinge 那一家的老字來比對。資料沒有說明「嗓音」和「味道」這兩支是怎麼長出來的，所以這裡只把它們當成同一股銳利的延伸畫面，不當成字源上的傳承。

Three branches
那一聲本身
這一組就站在核心畫面上：名詞是那個聲音，動詞是發出那個聲音的動作。
noun · C1
A short, sharp ringing sound, like the one a tight string or wire makes when you pull it and let it go — for example a guitar string, a bow string or a rubber band. In music it is also the name for the sharp, bright sound an electric guitar can make.
嗡的一聲（撥弦聲）
那股銳利跑進嗓子裡
弦上那股「緊、亮、帶鼻子」的味道，被拿來寫人的聲音。這是一個好用的畫面，資料沒有說這是字源上的路線。
noun · C1
A sharp, slightly nasal quality in someone's voice — part of the sound comes down the nose as well as out of the mouth. The word is also used for a light trace of a regional or foreign accent that you can hear in the way someone speaks.
（說話的）鼻音腔調
那股銳利跑到舌頭上
聲音上的「突然又刺」被借去寫味道。同樣是畫面上的連結，資料沒有交代這一支的來歷。
noun · C2
A sharp, strong taste that stands out — often a sour or spicy edge. It can be a good thing, as in yogurt or vinegar, and it can also describe a taste that is slightly off.
（食物的）嗆味／酸勁
