Luna:Text to Speech Demo

Cobalt's Luna technology powers all our text-to-speech projects. For this limited demo, spell out all the text as you want it said: e.g. "nineteen eighty four" or "one thousand nine hundred eighty four" rather than "1984". Why?

For a production deployment of Luna, we specify custom rules to determine how numbers, symbols, acronyms, etc. should be verbalized. We do not include these tokenization rules for the demo because the same input may be verbalized differently in different contexts (e.g. "7-11" might be "the seventh of November" in the U.K. or "July eleventh" in the U.S. or even "Seven Eleven" the brand name).
