What is wrong with people? Everyone thinks they have an expert opinion about everything. Maybe you are a linguistics expert? Really? Whatever…store and door don’t sound the same when you remove the s! It’s two totally different words and they are pronounced totally different!
End of story…I’m out!
What makes you think you know me?
This is a fun and interesting thread let us keep it that way please 
This is exactly what I’m talking about but I don’t have a PhD in linguistics. English words are pronounced differently and taking the s off of a word doesn’t make it sound the same. It’s pronounced differently. I’ll let the experts explain it.
To settle this:
This is store: https://voca.ro/1nxg8zLjK8mp
This is store with the initial s clipped off in audigy: https://voca.ro/1iFPpOstNbzB
This is door: https://voca.ro/1xITjUDkDWKI
And this is tore spoken out as a standalone word (without being clipped off of another word): https://voca.ro/1bqqV6UY7oVV
Please don’t take offense. I didn’t mean to totally direct this at you. It’s just a broad statement. English is a strange language for non native English speakers. I will admit it’s not even the best language but it’s the only one i know. I didn’t mean to offend and sorry if i did. Just trying to say that the words may sound the same for non native English speakers but they don’t to me because i know how to pronounce the words and maybe they don’t. I’m not a linguistics expert i just know how to say the words because that’s what i learned. I don’t know all the nuances of how and why and how to explain it using my PhD voice. 
You are correct in terms of aspirated and non aspirated etc. We don’t get taught linguistics so i would never be able to explain something in those terms. All i know is if the person is pronouncing the words as they are meant to be pronounced in English they don’t sound the same.
Native English speakers would never pronounce those words like that!
So sir, I want to know the fact that why do we write silent letter in spellings of few words; even if they don’t affect the pronunciation ?
As English is not my native language, hence someone with proficiency level like you can provide the idea behind it…
As a native Briton and English speaker having been brought up in England with a southern English accent I am going to throw in my piece to this discussion.
Having read through most of this thread I must say I agree with @Kresimir about the t & d oddity. I have sat here repeating the words and have to draw that conclusion.
I’m not sure about Canadian pronunciation (only briefly been twice) but an American English speaker could not hope to replicate British English very accurately (I’ve been all over the US). Also as a little friendly dig at you Yanks: Why do you pronounce t (when in the middle of a word) as d? For example forty becomes fordy, snotty would become snoddy etc etc! 
This illustrates my point perfectly, thanks @anon31549144!
Speaking as a North American - I don’t think residents of the UK have any room for taking others to task for pronunciation differences… explain lieutenant! 
Even with the excuse that it ‘came from elsewhere’…
As for MY accent - I grew up in a variety of locations, so my accent has a tendency to ‘float’, depending on what I am hearing from another in a conversation… even in Yorkshire! Too much time in a Hampstead prep school, and the Lake District, and travelling all over NA as well…
The points above only make sense when playing with the audio files - of course the pronunciation shifts when the speaker KNOWS what the word is before enunciating it! And then, depending on the person, they MIGHT be more clear than average in the first place - which affects the results of the testing too.
Like i said I’m not an expert on language or linguistics. I just know what i was taught as a native English speaker born and raised. I do not speak any other languages expect some French. Again i am not from France and Quebec French or French as it is taught here is not the same either as it is spoken in France. I only know that the way words are pronounced here don’t sound like some are saying. It’s just not. In English we say store and door does not sound the same as dropping the s on store because that word then becomes tore. They all sound differently when pronounced properly in English. That’s all i can say. I am not an English teacher, linguist or a PhD in any of it or a speech pathologist. I’m just a native English speaker and these are normal vocabulary. They are everyday words used by most. We are not talking about words that most of us don’t use such as higher level more intricate written and spoken vocabulary. Most everyday people are not scholars of the English language. But we do know how to say the words properly. Some people have speech problems. If they do not get the help needed when they are young to correct that then those speech issues will follow them their whole life. So they may pronounce words incorrectly because of that. In the schools here they try at an early age to identify those issues and have early intervention as we do have language speech pathologists here in the schools to work with those children identified as having speech impairments.
The examples that @anon31549144 has provide sound to me like a non native English speaker pronouncing those words. I can tell you they do not sound like that in proper native English by a native English speaker.
They just don’t. 
No offense!
I think perhaps you missed the point - when the longer word is spoken, it can be (and often is) uttered differently than the shorter word contained within it is. This is the same ‘place’ that contractions come from over time, btw. I still remeber arguments with English teachers over “You can’t say would of done” - when I actually said “would’ve done” which is possibly quite correct.
Another thing that comes to mind is that native speakers often do not put much ‘effort’ into pronunciation, as they ‘already know’ from what they hear around them. For instance, my accent speaking French is FAR superior to my knowledge of and capability with the language! All too often, the NEXT phrase spoken to me is WAY too fast because the sound misleads them into thinking I know what I’m doing!
Sir, I think you had misinterpreted my question. I only asked about the point which confuses me because I don’t have knowledge of it. You being the native English speaker, can provide some facts to my point which I may not be aware of.
It’s just the way google speaks them out. it might very well not be the real thing. Sounds close enough to me.
Here’s an interesting thing I learned today while playing with these sounds. The link I gave above for the pronunciation of store, here’s how it looks in audacity:
There is a pause between s and tore (that’s why it was easy for me to separate it). You can’t really feel it while listening, but the pause is there, waveforms don’t lie.
You would have to give me an example of what you mean? I may not be able to articulate it properly as I’m not a professional.
I think the only way to test the theory is to record yourself and truncate as appropriate. You might be surprised!
BTW, as a Canadian I can point out significant differences in language usage and sounds in various places in Canada! We have to allow for the Newfoundlander somehow
There are many words like talk, calm, align, etc; where we don’t pronounce the letter.
For example, in word align, we say aline, not ah-li-g-n.
Yes you right. The s is longer…just like the video i showed which explains it as @pebcak was talking about aspiration. My point only is that if the words are pronounced properly they do not sound the same. Sure if people use lazy speech and slur their words. Then yes it’s going to sound the same because they aren’t pronouncing some of the letters as they are meant to be in the word.
