Unique Narration Software Automates Voice-Overs in PowerPoint® Presentations and E-Learning Courses

Speech-Over narration software generates voice-overs in PowerPoint© presentations from narration script text in seconds with built-in text-to-speech software.

This unique PowerPoint® add-in allows developers to add voice-over narration any time, any place. They can now develop, integrate and preview narration content during course development instead of adding a recording at the end.

By eliminating voice recording, Speech-Over can save 50% in course development time and 75% in updates.

Like a live presenter, Speech-Over doesn't just read the text on the screen, but rather expands on and explains text bullets and graphics from narration text entered and stored by the developer.

Speech-Over can sync the narration with PowerPoint animations of text and graphics or play it in the background. Optionally,  it can generate captions and speaker notes.


Speech-Over makes it easy to revise and update the narration due to changes in product, procedures and data by just changing the narration text.

Developers enliven the narration and make it more understandable by adding special punctuation in the text.

Speech-Over's narration is automatically converted from PowerPoint into the e-Learning video or web formats produced by the e-Learning authoring tools Articulate®, Captivate®, iSpring®, Camtasia® - and PowerPoint.

Excellent for e-learning, training, marketing, and education in small businesses, corporations, institutions, and government. Includes a commercial TTS voice license.

Speech-Over is a complete narration solution: It can combine microphone recording, audio files and text-to-speech voices on a single slide.

Why is Narration Important in Learning and Why Speech-Over?

Principles for the Best E-Learning

One of the early gurus of e-learning, Prof. Richard E. Mayer, defined the principles of great e-learning:

  1. Use words and graphics rather than words alone (Multimedia Principle)
  2. Present words as audio narration rather than on-screen text (Modality Principle)
  3. Synchronize spoken words with corresponding graphics (Contiguity Principle)

Present words as audio narration (2)

There are many reasons why audio narration is better for learning than on-screen text.

  • Visual overload - With only on-screen text, it is difficult to read the text and view the graphics at the same time.
  • Captures attention -The narrator's voice captures the learner's attention, sets a pace and motivates learning
  • More content - The narration delivers much more content. A two minute slide can have 300 spoken words but not more than 50 words of readable text.
  • Better understanding - The narrator uses phrasing and articulation in their speech to bring out the exact meaning of the material in a way that text cannot do.

Problem with recording: Because of time and cost constraints of voice recording and the difficulty of integrating it, many companies opt to  eliminate narration and settle for screen text only. :-(

Speech-Over Supports Learning Principles

Speech-Over supports the modality and the contiguity principles.

Modality Principle: Speech-Over overcomes the constraints of time and cost of voice recording in narrated e-learning by using text-to-speech voices to create and update a narrator's voice track more quickly and inexpensively than by recording and it automatically integrates the narration into the course. :-)

Contiguity Principle: Speech-Over automatically syncs the narration with the corresponding text and graphics.
