Why do I mishear?

absolutely yes its me that has the problem  ----

with the person mentioned it is entire sentences for me. But like I say he a very nice guy and went out of his way to make me feel ok  by emailing documents of what he wanted me to do. His techniques of helping where so good I put it to the entire team that his techniques should be used. 

Whys thr post been put as -1?

That's a good idea anyway. It sounds like it's you who has the problem not him. I work with low level English speakers so am used to communicating with people who others find difficult. There's also a man there who has had a stroke and has reduced communication but for some reason I can understand him when I think others would struggle. For others who have no problems communicating, I have more confidence now to ask them to repeat or I lean in more and block one ear out. I think in the past I wouldve just tried my hardest to listen and understand.

This missing words seems to be one word I miss-hear in a sentence. Or I'm told I said one thing when I swear I said another. I think sometimes my brain goes too fast.

yea there is one guy in work from Stoke and when he speaks I miss about 50% of his words. We came to an agreement that he would email me instead from a certain day onwards. I felt very stupid saying "what are u saying , can u repeat that" over and over. He clearing felt my embarrassment.

He is a really sweet guy and very accommodating.  

This happens to me and my partner, especially will tell me he said one thing when I most definitely heard another. I don't believe him most of the time but have to trust what he's saying is true as it isn't done maliciously.   It's happened a few times at work too. A colleague was telling me about fish pakoras she made. I asked what type of fish did you use? She said "it was chicken, I said chicken pakoras.  You are tired, go and take your break". No matter how tired I was, I still don't believe I miss heard her.

It's like when I feel awkward or am made to feel daft / awkward when I haven't got a joke or sarcasm. I mostly put it down to the other person's delivery.  Why's it always me who has to be at fault.

could be intentional to fit the tune.

or... could just be americans saying words wrong or in a weird accent to the point "one" in a song could be "worn" or "won" in the mistake that is american english lol

yes that an adhd/add thing i experience that all the time. I tend to only deal in now anything in the past is mostly archived.

I tend to remember most of what I heard before, but I sometimes need a few hints. My female friend I chat to on Google Duo is cool with it; and she can talk for Canada. (she's Canadian)

I have a partner who tends to start talking without bothering to set the context.

Me too      Also uses 'they' to refer to different people during the conversation or names of people who I've never heard of - it makes comprehension extremely difficult. 

..... And if you are also lacking some information about the context in which the singer is singing, all sorts of interpretations become possible. If Annie was accompanied with a video illustrating her plight, either literally or metaphorically, you might begin to perceive her lyrics a bit more accurately.

I have a partner who tends to start talking without bothering to set the context. She seems to think that if she provided the context as long ago as an hour or two (or even longer) ago, that I am going to hear her speak and immediately remember the previous context she provided. My problem is that I have nearly always been through hundreds of different thoughts since she provided that context earlier, and so I have completely lost her plot. (So that's also my issue, which seems to be ADD.) If only she would say something like "Do you remember what I said ..... earlier about ..... ?", before she launches into one of her monologues. If I begin to ask questions to establish the context, I get accused of being unimaginative. Now if only i could just get the idea over occasionally that I am perhaps being 'unimaginative' about contexts, ......  because my imagination is constantly running all over the place. ;-) Arghh!

But then again, perhaps we are both neurodivergent. I have seen and heard some evidence of that recently.

I can't memorise lyrics for s**te! So, I don't bother.

Your brain is programmed to detect words and will create them from barely perceived fragments of sounds - so depending on how the sound is presented to you, its frequency response and volume levels and the angle it hits your ears, anything is possible  

I used to love the "Maxell" adverts.   https://www.youtube.com/watch?v=Gib916jJW1o   or    https://www.youtube.com/watch?v=mxELSzay2lc    

Hard to tell whether it's accidental, or intentional. More likely the latter, but we live in a World which vindicates scepticism.

depends what modulation the radio was using FM  or AM   on AM the sound can warp no problem then add some inconsistency from the singer and unless u know the lyrics it would be very common to misunderstand a radio.

FM radio is better an FM DAB is really clean sound 

as for real life i have found people with certain rhythms i can't make out what they are saying. I went and got my ears tested and they said u are way above normal :)    so the conclusion is that my hearing - speak brain processing is faulty at certain frequencies/volume/word rhythms.

There isnt much I can do about it so I was offered an MRI but I decided it wasnt worth the hassle

singers tend to warp their words to make it sound better musically and force it to fit.

as for people, people mumble when they talk and dont speak clearly enough. would probably be handy if they ditched some pointless lessons in high schools and replaced them with elocution lessons perhaps, to make everyone less mumbly. would help them in life more than gender studies or religious education anyway lol
