The spelling of the German word "Lachs" is quite tricky, as it does not follow the typical phonetic rules. The word, which means "salmon" in English, is pronounced as "laks," with the "ch" being pronounced as a voiceless velar fricative sound, similar to the "ch" in the Scottish word "loch." In IPA phonetic transcription, the spelling of "Lachs" would be /laks/, with the "a" sound being a short vowel, and the "s" being pronounced as a voiceless alveolar sibilant.
