VTML (VoiceText Markup Language) – This Powerful hidden gem in Text to Speech helps you control the generated speech by adding pause, changing the pitch etc !
This post on customizing text to speech Pronunciations received many comments requesting a way to control the generated speech with html like tags.
The interesting thing is that this feature is already there in Captivate 4 ! Even more interesting is the fact that it is so simple to use. All you need to do is insert the appropriate tags into the slide notes. You can type in (or copy paste) the tags just like you do any other text.
Just before making this post, I quickly tried few of them:
1. Hello I am here <vtml_pause time=”1000″/> for a break: Introduces a pause of 1 sec in between.
2. <vtml_speed value=”50″> This is my text </vtml_speed>: Helps you control the speed of the text
There are many more similar useful tags. The VTML tags are listed in the Appendix C of the document here. It has a examples as well on the usage.
