German final devoicing: why 'und' ends in a T
At the end of a word or syllable, German b, d, and g switch to their voiceless partners. Written b is said as p, written d as t, and written g as k — so 'und' ends in a t sound, 'halb' in a p sound, and 'Tag' in a k sound. The spelling never changes; only the pronunciation does. It is one rule, it has almost no exceptions, and it affects hundreds of everyday words.
What voicing actually is
Put a hand flat on the front of your throat and say a long 'zzzz'. You feel a buzz: your vocal cords are vibrating. Now say 'ssss'. No buzz. Same tongue position, same airflow, voice off.
English pairs its consonants this way throughout: b and p, d and t, g and k, v and f, z and s. Within each pair, the mouth does the same thing and only the voicing changes.
German does the same, with one extra rule English does not have: at the end of a word or syllable, the voiced member of the pair is not used. The voice switches off and you get the voiceless partner instead.
That is the whole mechanism. You are not learning a new sound — you already have p, t, and k. You are learning to put them somewhere your English habits want a b, d, or g.
Where the rule applies
At the end of a word: und ends in t. Hand ends in t. Kind ends in t. Tag ends in k. Weg ends in k. Berg ends in k. halb ends in p. ab ends in p.
Also before a consonant inside a word, where the syllable closes: 'gibt' has a p in the middle, 'sagt' has a k, 'lebt' has a p.
And it survives inflection asymmetrically, which is what makes it visible. 'Tag' ends in a k sound; 'Tage' has a real g, because the vowel that follows opens the syllable back up. 'Kind' ends in t; 'Kinder' has a real d. 'halb' ends in p; 'halbe' has a real b.
The one thing that looks like an exception is the ending -ig, which does not become k in standard pronunciation. 'richtig', 'wenig', and 'König' end in the soft ch of 'nicht' instead.
Why English speakers get it wrong
English keeps voicing at the ends of words. 'Bed' ends in a d, and the d is at least partly voiced. More importantly, English signals the difference between 'bed' and 'bet' partly by making the vowel longer before the voiced consonant.
So an English speaker saying 'und' does two things at once: keeps some voicing on the final consonant, and stretches the vowel in front of it. Both are wrong in German, and the second is the more audible of the two.
The fix is mechanical and complete: same tongue position, voice off, vowel kept short and clean. Say English 'oont' rather than 'oond' and you are much closer.
This is a low-effort, high-return item. It requires no new sound and no new muscle control, it applies to some of the most common words in the language, and getting it wrong makes hundreds of words sound subtly off at once.
Drilling it
Work in pairs, because the pairs are what make the rule audible.
Tag / Tage. Kind / Kinder. Weg / Wege. Hand / Hände. halb / halbe. Berg / Berge.
Say the singular with a hard, short, voiceless ending, then the plural with the voiced consonant restored. Feel your throat: buzz off, then buzz on.
Then take the words that hide the devoicing in the middle: gibt, sagt, lebt, jagt. Slow them down and listen for the voiceless consonant before the t.
Then run the most common words on their own, until the ending is automatic: und, Kind, Hand, Tag, Weg, ab. 'Und' is worth ten repetitions of its own; it is one of the most frequent words in German and one of the most reliably mispronounced.
Keep the vowel short while you do it. If the vowel stretches, the English pattern is still running underneath.
What to listen for
Record 'und' and listen to the last consonant with your eyes closed. Does it sound like the t in English 'ant', or like the d in 'and'? It should be the first.
Then check the vowel length. Record 'und' and English 'oond' back to back — if your German vowel is as long as the English one, shorten it.
Record the pair 'Tag' and 'Tage'. If the consonant sounds the same in both, one of them is wrong. In 'Tag' it should be a clean k; in 'Tage' a clean g.
In TonePerfect, the consonants at the ends of words are scored like every other sound in the word, and your recording comes back with your sounds ranked weakest-first — which is the practical way to check whether the endings you think you have fixed are actually coming out the way you intend.

Questions
Does final devoicing change the spelling?+
No, and that is what makes it easy to miss. German keeps the letter that appears in the related forms — Tag is written with a g because Tage has one — while the pronunciation switches to k. You have to read the word's position, not its letters.
Does it apply to v, z and s too?+
The rule that learners need is the one covering b, d and g, because those are the pairs where the spelling stays voiced and the pronunciation does not. German z is always a ts sound regardless of position, and s at the end of a word is a plain hissing s rather than a buzz.
Why doesn't -ig become a k sound?+
The standard pronunciation of the -ig ending is the soft ch of 'nicht': richtig, wenig, König. It sits outside the b/d/g pattern and is worth learning as its own item, since -ig is an extremely common ending.
Will people misunderstand me if I ignore it?+
Rarely, since context does most of the work, and there are few pairs where the ending alone carries the meaning. But it affects so many frequent words that ignoring it leaves a consistent accent across your whole speech — and it is one of the cheapest things in German pronunciation to fix.
