So, lately I've been really interested in the 'DEVOICING 'Voiced Consonants to thei r counterparts'. I've been doing many studies painstakingly, so I would like to share it with you, and you can tell me if you agree with me or not.
So, I'll start:
- I have two bookshelves= See in this case the word 'HAVE' is pronounced with a 'V' sound, however, due to the fact that the next word is a 'T', it becomes an 'F' sound. 'Bookshelves' is pronounced with a 'V' sound and with an 'Z' sound, however, due to the fact that is at the end of a sentence, the 'v and the 'z' sound, will transformed into a very but very ultra week 'F, 'S' sound. So the sentence= aɪ hæv tu ˈbʊkˌʃɛlvz, actually becomes= aɪ hæf tu ˈˈbʊkˌʃɛlfs= This is how google translator pronounces it: https://translate.google.com/?hl=es#view=home&op=translate&sl=auto&tl=es&text=I%20have%20to%20bookshelves
2.Vegetable= ˈvɛʤtəbəl. Pronounced with a 'J sound', however, it you try to pronounce vegetable with a 'J' sound, it is possible, but it's hard, and not only that, but it sounds unnatural. So, due to the fact that the next sound is a 'T' sound, it'll mean that the word 'VEGETABLE' will actually become = vɛʧtəbəl. The 'j' sound will convert into its counterpart consonant, which is the 'Ch' SOUND. https://translate.google.com/?hl=es#view=home&op=translate&sl=auto&tl=es&text=vegetable
3.The phrase= You've changed a lot= So, the 'Ch' sound is actually a mix between the 'T' sound and the 'Sh'= ʧ. sound' ʧ. So it means ,that it'll apply the same rule as deovoicing as the 'T' sound. So, It seems like the 'V' from you've will become a very weak 'F' sound, instead of a hard 'V' sound. Not only that, but it seems like the 'J' sound from "changed" will become a very weak "CH" sound", so... juv ʧeɪnʤd ə lɑt.= juf ʧeɪnʧt ə lɑt. Not only that, but it seems like the 'D' from changed will become more of a 'T sound. Keep in mind, they're becoming very weak counterparts. Here's the audio: https://translate.google.com/?hl=es#view=home&op=translate&sl=auto&tl=es&text=you've%20changed%20a%20lot
He's trying= The same will happen here, He's is pronounced with a Z sound, however, due to the fact that the next word starts with a 'T' sound', well, it'll actually be more of a 'Ch sound' since it's more common to pronounce the 'TR' cluster as a 'Ch' sound. So, hiz ˈtraɪɪŋ, will become more like= hisˈtraɪɪŋ= Audio:
I moved. Here will happen something= "Moved" is at the end of a sentence, so this means, that the 'V' sound from moved, will become a very ultra light 'F' sound.
The 'T' and 'Ch sound, seem to devoice many things.
'You move to me' 'I have to go' 'I've been ENGAGED TWICE'(see the 'J' sound will become more of an 'Ch sound)
This also happens at the end of words= So. "Never in my wildest dreams"= The 'Z' from dreams, will actually be a very ultra light 'S', so light, that it'll sound like a little whispery s SOUND.
Same with. "I have a page"=. THAT 'J'. will become a very ULTRA light 'Ch sound, instead, since it's at the end.
However, if you say: "In my dreams I see you" Then, that 'Z' sound will be strong.
If you say: "I'm gonna change my name" Then that 'J' sound will be strong.
"I'm gonna move again"= In this sentence the 'V' sound, will remain and it won't change to a 'F sound.
One last more: "It won't change to a 'F sound". See, the "CHANGE TO", that 'J' sound, will actually change more to a 'Ch sound' since the 'T' sound, devoices it.
Same with, 'I have a garage= When it's at the end it seems it becomes a very ultra light 'Sh' sound instead of the 'Zh' sound. But if you say: "My garage is big" Then no, that 'ZH' sound will be strong and remain!
