Text-to-Speech Overview and NLP Quality

Tony Karrer

It took a couple more years for me to say (in 2009) that virtual classrooms reached a tipping point. Text-to-speech can create professional voice narration without any recording which provides significant advantages: keeps narrated presentations continuously up to date (it's too time consuming/expensive to rerecord human narration) faster development - streamlined workflow lower costs. A better way is to use modulation tags to directly emphasize a word.
