I live in germany, and i pray mostly at home, as no mosque is nearby. I usually recite surah fatihah and next surah aloud because its make me focus more and it helps in memorisation. Is it okay if i recite loudly in all the salah even in dhur and asar, where the sunnah is to recite slow?

Ustadh AbdulAziz al-Haqqan

No, don't go against the Sunnah. In Dhuhr and Asr, pray silently. In the other salawats and in your voluntary prayer, you can pray out loud.
