It's one of the most difficult things to pick up when learning Japanese as well. There are lots of words that are basically homophones except for vowel length and tone. To an English speaker they tend to sound identical, but to a Japanese speaker if you get it wrong the result is unintelligible. For example "地図" (in romaji: chizu and pronounce cheezu with a short "ee") is "map" and "チーズ" (in romaji: chiizu and pronounced cheezu with a long "ee") is "cheese" (though they have the same tones... I'm struggling to think of an example with different tones as well as vowel length).
The thing that helped me the most for this was singing songs. Once you understand that there is a necessary rhythm to the words, it makes it much easier to use that rhythm in speaking. Or at least it did for me -- YMMV.

(the major difference you hear is the long ii, rather than the t/d difference)
A phone is a class of sounds (as opposed to their instances which are all unique) that can be reliably described by articulatory or acoustic features (phonetics) or by patterns found in EEG (I'm thinking of MIT's voiceless mic).
A phoneme is another type of "sound" class used in linguistics and it is arguably the more important: phonemes, as studied in the context of a particular language, is the finite set of sounds (a few dozens at most) from which you build different words in that language. Phonemes always come in pairs, since they are defined as the minimal distinctive linguistic unit that can yield a difference in meaning.
Substitute /p/ with /f/ in/fear/ and you get /pear/, i.e. another word, a difference in meaning --> thus /p/ and /f/ are phonemes.
But substitute /r/ with /rrrrr/ in /Braveheart/ and you get the same word but with a scottish accent. These do not form a phonemic pair but allophonic variations of the same phoneme (here according to different geographic areas but they can also vary according to age, social status, gender, etc ...)
Bare in mind I'm not a Linguist, but my take on this is that the word Ratte just flows out of my mouth under one breath. The second syllable is is made without needing to "stop my voice" if that makes sense… I just move my tongue up to the top of my mouth to make a small `-t-` sound. Ratte is pronounced very quick.
Rathaus, on the other hand, there is a something like a full stop (but not really a full and total silence) in between `Rat-` and `-Haus`. And for whatever reason, it seems like I pronounce the `-a-` in Rathaus longer than I do in Ratte.

Or better yet: "Luke", "look", and "luck"
And for Spanish speakers there's "Jeep", "sheep" and "cheap"
I'm a non-native English speaker, and certainly has no problem distinguishing between your examples; in fact I use such words as illustration when explaining subtleties of Danish pronunciation to anglophones.
And I absolutely cringe whenever '2' is used for 'to', og '4' for 'for'. Just stop it, they sound nothing alike.
I'm a native english speaker, and I pronounce those the same.
Two = to = too, but "tool" sometimes nearly has 2 "o" sounds, depending. For = four, and the sound in "four" is not the same as in "foul", which is two sounds.
What's the concrete difference? Global rising or falling? Upsteps/downsteps? Pitch contours?
