Intelligibility is how easy it is to understand speech, writing, or an idea. If a recording has high intelligibility, you can catch the words even when there is noise. If a text has low intelligibility, you see the sentences but cannot hold the meaning.

Intelligibility Intelligibility is指的是 how easy it is to understand speech, writing, or an idea要理解說話、文字、或一個想法有多容易。If a recording has high intelligibility如果一段錄音的intelligibility很高，you can catch the words你也能聽懂每個字 even when there is noise就算有噪音。If a text has low intelligibility如果一段文字的intelligibility很低，you see the sentences你看得到句子，but cannot hold the meaning卻抓不住意思。

People who teach speaking, and people who make phones and hearing machines, use this word a lot. It is a little technical.

People who teach speaking教口說的人，and people who make phones and hearing machines還有做手機和助聽器的人，use this word a lot很常用這個字。It它 is a little technical有點技術性。

In ordinary talk most people just say “I can understand it” or “it is clear.” It is not the same as intelligence, which is about being clever. A clever talk can still have poor intelligibility if the speaker does not open their mouth enough.

In ordinary talk在一般的對話裡，most people just say大部分人就只會說 "I can understand it" or "it is clear."「我聽得懂」或「這很清楚」。It它 is not the same as intelligence跟intelligence不一樣，which是 about being clever講的是聰不聰明。A clever talk一場聰明的談話 can still have poor intelligibility仍然可能intelligibility很差，if the speaker does not open their mouth enough如果講者嘴巴張得不夠開的話。
