聞こえにくいって英語でなんて言うの？

「私はあなたがよく聞こえない」が直訳です。

このように言うのが一般的かと思います(^^)

その直前にI'm sorry butなどと付けると丁寧な響きがするでしょう♪

have trouble hearing = よく聞こえない

他のアンカーさんも仰るとおり、sorryを前につけると良いです。

Sorry, I'm having trouble hearing you.

Here are two very easy ways to say that you can't hear someone very well over the phone. Notice that the first example is using the verb, "to be able to (can)," to express our ability to hear something. The second example is using the verb, "to have," with the adjective, "trouble," to express this same ability to hear.

The three sentences you see provided above are excellent ways to express to your listener that you cannot hear them on the phone. In the second sentence you will see the term break up and in the second sentence you will see the word choppy. They both mean unclear. We use this term and this word a lot when we cannot hear someone on the phone, these would make great additions to your vocabulary.

As we all know, we can have problems when speaking to people over the phone. This is especially true when we are using mobile phones. We or the other person may be in an area where there is bad reception or just a lot of noise.

We can use either of these two sentences to let somebody know that we can't hear them very well.

When you are on the phone with someone and cannot hear them properly; you may let them know in the following ways:
-Pardon? I missed that. Please say that again.
-I cannot hear you very well. Can you please say that again?
-I have trouble hearing you. Can you please say that again?

If you cannot hear someone very well when you are on the phone, you could say any of the following to express this: "I can't hear you very well, I think the connection is not great", "The line seems to keep breaking up" or "I can't hear you very well".

1. When the signal is poor and the person's voice disappears, you would say, "You are breaking up", the speaker would immediately know to repeat themselves as you did not hear them clearly.
2. This is the same as 1 (above), BUT the speaker would not know you did hear them. So say it like this, "The connection is bad, please say that again".
3. This sentence can be used as it is written.
