"I do not like soup at all."
Translation:Cha toil leam brot idir.
The ch is like the ch in "loch", as in Loch Lomond. From an American English speaker's point of view, it's placed fairly deep in the throat; we don't place anything there except throat-clearing. (In another discussion the Scotts thought it was a pretty normal place to put a sound, and not deep in the throat at all, but...)
I've no idea what you heard, as they've changed the recordings around a lot and fixed some of the problems. I do know there's a lot of Scottish Gaelic pronunciation variation from place to place though.
ch (…) it's placed fairly deep in the throat; we don't place anything there except throat-clearing.
That’s not true. It has the exact same place of articulation as (English) /k/ and /ɡ/, ie. it is a velar consonant (the tongue gets close to the velum AKA soft palate). The only difference between /k/ and /x/ (the ch sound) is that /k/ is a stop and /x/ is a fricative. That means that when you say /k/ you entirely block the air flow with your tongue (you stop the air flowing) while for /x/ you put your tongue in the same place but instead of blocking the air flow you just obstruct it a little to create friction.
It’s a similar difference as between English /t/ (a stop) and /s/ (a fricative).
It’s definitely not deep in the throat (it’s possible to make consonants further back there, eg. German ch might be [x] like in Gaelic but also it might be uvular [χ], or French /r/ is voiced uvular [ʁ] – the tongue indeed closing to uvula a bit further down, or Arabic has eg. /ʕ/ – a pharyngeal fricative that indeed is made in pharynx, in the throat… – but none of that in Gaelic, its /x/ has the same exact place of articulation as /k/).
As for the original comment – I remember there being some more comments about weird sound for cha, so I guess there was something wrong with the recordings (or maybe some bug with playback distorting beginning of the recordings?) at some point, but since I don’t see newer reports like that, I guess it’s been fixed?
Yes, well, there are no fricatves placed in the throat like that in American English, and IMO while as you say the shape of the sound is placed where the k is, the action and vibration of the airflow is distinctly deeper in the throat than the action for the k. It's not something we know how to coordinate. There is a similar sound in the same position in Hebrew, though less aspirated, and my (largely expert) church choir sat around teaching it to each other -- all describing that as "deep in the throat" -- and with the additional aspiration and extra coordination needed for the Gàidhlig "ch," it feels even deeper. This is a sound I presume you have in your linguistic repertoire; it's not one we have.

But it’s not. It’s really the same place as /k/. The only difference being the manner of articulation. You’re right there is no such phoneme in English and it might not be easy or natural for native English speakers to produce this sound but it’s in no way ‘deeper in the throat’ than /k/ is.
