When I listen to the pronunciation of amtlicher on Dict.cc, I hear the letter t pronounced more like g or k. At least I do not hear it as a clear t. Can somebody please explain how t is pronounced here?
For both 't' and 'l' the tip of the tongue is in the same spot (on the speaker's alveolar ridge, to be precise).
When 't' is followed by 'l', German speakers leave the tip of the tongue in that place, merely narrowing their tongue to go from one sound to the other. Thus, the release of the plosive 't' is very close to that of 'k' in this case.

Speech synthesizers as used by dict.cc are prone to an artificial pronunciation, especially when it comes to a finer differentiation of sounds. In this example the sound
t and the sound of
k may be very similarly reproduced by the computer generated voice.
