PPTX Speech Synthesis

Overview

Speech synthesis can be an effective tool for enhancing presentations by converting slide text into spoken audio. This skill details how to generate audio narratives from text in PowerPoint slides.

Text-to-Speech Conversion

You can utilize libraries such as gTTS (Google Text-to-Speech) to convert slide text into audio files:

from pptx import Presentation
from gtts import gTTS
import os

# Load the presentation
prs = Presentation('path-to-file.pptx')

# Extract text and convert to speech
for slide in prs.slides:
    text = ''
    for shape in slide.shapes:
        if hasattr(shape, 'text'):
            text += shape.text + '\n'

    # Create audio file
    tts = gTTS(text)
    audio_file = 'slide_audio.mp3'
    tts.save(audio_file)

    # Optionally play audio or attach it to the slide
    os.system(f'start {audio_file}')  # Adjust command for OS

Conclusion

Integrating speech synthesis into your PowerPoint presentations allows for a dynamic and engaging format for delivering content, enabling accessibility and enhancing audience comprehension.
