Narration works best when each slide has its own short script. Write one script per slide, keep each to a few sentences, and convert them one at a time. That way a change to one slide never forces you to redo the whole deck.
Name the MP3 files in slide order, such as slide-01 and slide-02, and keep the script text next to them. Most presentation software can insert an audio file on a slide and play it automatically or on click; check how your software does it and test the slide show once from the start.
Use short sentences, write numbers as they should be spoken and spell out abbreviations once. Do not read the slide word for word: say what the slide shows. Listen to each clip with the slide on screen to check the timing.
