Speaker notes in PowerPoint play a crucial role in enhancing the presenter's delivery and ensuring a seamless presentation experience. They can be added to individual slides to provide valuable guidance, reminders, and supplementary information for the presenter. Unlike the content displayed on the slides, speaker notes are typically not visible to the audience during the actual presentation. In this article, we'll explain how to add, read or delete speaker notes in a PowerPoint presentation in Python using Spire.Presentation for Python.

Add Speaker Notes to PowerPoint in Python

Spire.Presentation for Python provides the ISlide.AddNotesSlides() method to add notes to a PowerPoint slide. The detailed steps are as follows.

• Create a Presentation object.
• Load a PowerPoint presentation using Presentation.LoadFromFile() method.
• Get the slide that you want to add notes to using Presentation.Slides[index] property.
• Add a notes slide to the slide using ISlide.AddNotesSlides() method.
• Create TextParagraph objects and set text for the paragraphs using TextParagraph.Text property, then add the paragraphs to the notes slide using NotesSlide.NotesTextFrame.Paragraphs.Append() method.
• Save the resulting presentation using Presentation.SaveToFile() method.

from spire.presentation.common import *
from spire.presentation import *

# Create a Presentation object
ppt = Presentation()
# Load a PowerPoint presentation
ppt.LoadFromFile("Sample.pptx")

# Get the first slide
slide = ppt.Slides[0]

# Add a notes slide to the slide
notesSlide = slide.AddNotesSlide()

# Add 4 paragraphs to the notes slide
paragraph = TextParagraph()
paragraph.Text = "Tips for making effective presentations:"
notesSlide.NotesTextFrame.Paragraphs.Append(paragraph)

paragraph = TextParagraph()
paragraph.Text = "Use the slide master feature to create a consistent and simple design template."
notesSlide.NotesTextFrame.Paragraphs.Append(paragraph)

paragraph = TextParagraph()
paragraph.Text = "Simplify and limit the number of words on each screen."
notesSlide.NotesTextFrame.Paragraphs.Append(paragraph)

paragraph = TextParagraph()
paragraph.Text = "Use contrasting colors for text and background."
notesSlide.NotesTextFrame.Paragraphs.Append(paragraph)

# Set bullet type and style for specific paragraphs
for i in range(1, notesSlide.NotesTextFrame.Paragraphs.Count):
    notesSlide.NotesTextFrame.Paragraphs[i].BulletType = TextBulletType.Numbered
    notesSlide.NotesTextFrame.Paragraphs[i].BulletStyle = NumberedBulletStyle.BulletArabicPeriod

# Save the resulting presentation
ppt.SaveToFile("AddSpeakerNotes.pptx", FileFormat.Pptx2016)
ppt.Dispose()
