Text to Speech is certainly one of the coolest features of Captivate 4. e-Learning course developers no longer need to budget for the time and cost of audio creation. This adds a new dimension to rapid authoring. And where individual users like trainers, managers, and software developers are concerned, they can now independently create a movie complete with audio.
All you need to do to generate the audio for a slide is add slide notes and select a voice. Captivate converts the slide notes into audio in seconds. If you want to generate audio for multiple slides in one go, you can use the Speech Management option.
The step-by-step procedures for converting text to speech are documented here.The converted speech sounds pretty good. Common abbreviations like TOC and SAP are converted intelligently. If required, you can even customize the text to speech dictionary and alter a pronunciation. Or you can add VoiceText Markup Language (VHTML) tags in the slide notes to add a pause or tweak the speed of the generated audio.Mukul Vinay Lele gives step-by-step instructions for customizing pronunciations here.For more information about VTML tags, read this post by Sony Kadavan.
