I updated the mosquito speak skill with some additional functionality (https://github.com/CarstenAgerskov/skill-mosquito-speak).
The skill is now able to say words like CamelCase or hyphen-variable. It works by applying a regex expression to the text it receive, and based on matches split and add speces before speaking it. See the skills README for more details.
I use this skill to notify me of events in my home automation system, and often the automated responses contains CamelCase.
