In the name of Allah the most Gracious the most Merciful
The answer to your question is as follows:
The art of Tajweed and Qiraat is meant only for the recitation of the Holy Quran. While reading the Holy Quran, the Quranic Phonetics should be observed. There is no need for Tajweed while reading Hadith. However, the hadith should be read clearly and in the Arabic accent, observing the rules of the Arabic language.
And Allah knows best
