I don't know if I should trust my non-native ears, but I've heard a couple of people (Katie from CollegeHumor is the first one come to mind) who say "thank you" with a voiced "th" instead of the proper voiceless one. Also quite a couple of people seem to have said "princible" instead of "principle" (like those guys from Corridor I think). I don't remember the exact videos where they say those words for demonstration, though.

So do Americans often voice their voiceless consonant if at all? Discounting intervocalic voicing which is more of a historical thing that happened centuries ago ("knives, clothes, Stephen"), this seems counter-intuitive to me, because it's more natural to devoice voiced consants, especially at utterance boundaries or if that consonant is next to a voiceless one (e.g., "slide" + a pause, in which /l/ is slightly devoiced because of /s/ and /d/ slightly so because of the following pause). Also discounting the North American tapped /t/.

  • Hello Vun, I am from the US and I have never said Thank you with a voiced th. I also have never voiced the p in priniciple except when someone is congested and can't do the non-voiced or from little kids who are learning. I have never watched the shows you are talking about, but it would sound very weird to me. But remember that there are a great number of regional pronunciations in the US, so each can have different pronunciations.

    The only word that comes to mind is congratulate, which some Americans now pronounce voiced. American schoolchildren might think the head of their school is a princibal, but they grow out of it.

    Also the loan word kindergarten, which is almost always pronounced and frequently misspelled "-garden."

  • @shoover In AmE most intervocalic 't's are not aspirated (like in BrE) but are instead lenited to a flap (so 'writer' and 'rider' sound identical). But this certainly could be an instance of the OP.

No, it isn't that common to voice voiceless consonants. It does happen sometimes, though (the biggest example of course is intervocalic /t/ in certain contexts).

The two examples that you give are quite specific.

  • Voicing the initial th in thank is known to be a feature of some people's speech (See Voiced “th” in “thank you”? on Linguistics SE and Pronunciation of "thank" using ð (voiced th) instead of θ (unvoiced th) on ELU). The distinction between voiceless and voiced th does not have a large "functional load" and it isn't indicated in the spelling, either.

  • I hadn't heard before about voicing the p in principle. It seems possible that this is partly an analogical change based on the large number of words ending in -able/-ible—although those are mostly adjectives, while principle is a noun. Based on Google results for the spelling "multible", the word multiple may be another word where some people voice /p/ to /b/ when it comes after an unstressed vowel and before word-final /əl/. I haven't heard of any analogous change of voicing /kəl/ to /gəl/ in words like miracle, article, vehicle, oracle.

In some words, sibilant sounds may be unexpectedly voiced.

  • KarlG mentions the use of voiced /dʒ/ in congratulations. Some speakers use voiced /dʒ/ word-finally after an unstressed vowel in certain words where /tʃ/ would be expected from the spelling, such as ostrich, sandwich. I don't know if this /dʒ/ is actually phonetically voiced, or just phonemically voiced. Actually, the variation between /tʃ/ and /dʒ/ after unstressed vowels seems to date back to Middle English, so it didn't originate as a specifically American English thing (it's discussed in § of "Change in Obstruent Laryngeal Specifications in English: Historical and Theoretical Phonology", by Magdalena Jeannette Spaargaren, 2009).

  • Voiced /ʒ/ is used where /ʃ/ would be expected in a number of words, such as equation, words ending in -rsion (version, dispersion, immersion), and fission. The pronunciations with /ʒ/ have varying frequencies for each word depending on the dialect. Using /ʒ/ in -rsion words seems to be a specifically American English thing, while using /ʒ/ in equation is usual in all major varieties of English as far as I know.

  • The distinction between /s/ and /z/ is relatively unstable in certain contexts/words (interchange between these is probably facilitated by the use of the letter S to represent both sounds). The final consonant of versus is often voiced (even by speakers who have not reanalyzed the word as an inflected form of a verb "to verse").

  • /ʒ/ in fission? That’s definitely a new one to me. Sounds like a Dutchman saying vision! Oct 23, 2018 at 17:48

    @JanusBahsJacquet: It's probably influenced by the /ʒ/ in fusion.

  • Still sounds very odd to me, unlike princible and multible, which sound perfectly unremarkable to me. I could easily imagine myself saying those in normal speech (though probably not discible, presumably due to the different stress), but I think I’d actually be confused if I heard someone say fizzion, and wonder whether I’d understood them right. (There’s also cases like possess, parallel to equation but with /z/ for /s/ instead of /ʒ/ for /ʃ/.) Oct 23, 2018 at 17:52
  • @JanusBahsJacquet: I didn't go into possess and similar words (dessert, dissolve) because the voicing there seems to have arisen before American English existed. But maybe I was being inconsistent, because the use of /dʒ/ in words like ostrich seems to be of similar antiquity.
