I'm also close to losing that distinction, but my MOUTH vowel is weird (see below).Imralu wrote: ↑Tue Apr 18, 2023 8:02 pmI almost have that merger. /æl/ and /aʊl/ are very similar. I'm not quite sure how to transcribe them. Having very velarised /l/s (in all positions) and tending towards vocalising them makes the offglide of /aʊ/ less noticeable I think.Nortaneous wrote: ↑Tue Apr 18, 2023 7:14 pmOnce I was talking to a linguistics grad student (from a few hours north of me - had the /æ/-/eə/ contrast) about the syllabification of words in <ow(e)l> and she thought I had a "Hal-howl merger". But MOUTH is [æə̯] here.
I just recorded mass and mouse in citation form, and the spectrogram is not what you might expect. In fact both seem to be monophthongal, with the main differences being:Nortaneous wrote: ↑Tue Apr 18, 2023 7:14 pm(I think the primary phonetic contrast between TRAP and MOUTH is that TRAP has some kind of +ARGH, although I don't know what this +ARGH is. Not the same +ARGH as Nuosu.)
- TRAP is further back (sic), with F2 around 1350Hz as opposed to more like 1650Hz for MOUTH.
- TRAP is slightly more open.
- MOUTH has a stronger (or perhaps just more concentrated) and slightly lower third formant.
Perhaps the last of these is -ARGH.
(I knew my accent had a reduced glide in MOUTH compared to most English accents, but I'm a little surprised that even in citation form I can't see one at all.)
