We asked Shaikh Saleem al-Hilali hafidhuhallah about spoken word during one of our classes and he said it is allowed.
Obviously it should be free of haram things like bad speech as comes in the Hadith:
عَنْ عَبْدِ اللهِ بْنِ عَمْرٍو قَالَ: قَالَ رَسُولُ اللهِ صلى الله عليه وسلم: الشِّعْرُ بِمَنْزِلَةِ الْكَلاَمِ، حَسَنُهُ كَحَسَنِ الْكَلامِ، وَقَبِيحُهُ كَقَبِيحِ الْكَلامِ
‘Abdullah ibn ‘Amr reported that the Messenger of Allah, may Allah bless him and grant him peace, said, “Poetry is in the same position as speech. The good of it is like good words and its bad part is like bad words.” [Saheeh Adab al-Mufrad no. 865]
Or taking a wage or imitating the disbelievers.
And Allah Knows Best
