Recording audio is an expensive affair, where you need to take services from a professional voice artist, have an audio recording studio, and buy expensive equipment and software. Moreover, if there are any edits required at a later stage, you need to redo the entire recording process.

Participants in this session will learn how generating audio using text-to-speech engines allows the eLearning designer and developer to quickly add narration to their eLearning courses at low cost. But this audio sounds mechanical and is not usable for professional courses—you need to treat the audio generated to make it sound more natural. Learn how VTML tags are the powerful hidden gems for text-to-speech audio that will help you control the generated speech by adding pauses, and changing things the pitch, volume, and speed.

In this session, you will learn:

  • How to use the VTML tags for text-to-speech voices
  • How to use VTML tags to generate natural-sounding audio
  • How to add text-to-speech in eLearning courses
  • Best practices of using text-to-speech in eLearning courses

Novice and intermediate designers and developers with basic eLearning course development skills.

Technology discussed in this session:
Adobe Captivate, text-to-speech engines.

Student technology needs:
Participants should have Adobe Captivate 7 installed.
