We have now built all the behavior for the timer, and it turned out to be pretty complex! We had to create new ways for the child to communicate back to the parent, and we had to implement behavior to pause the timer whenever an alert is shown, and it was pretty cool to see how we were able to accomplish these features.

OK, we are finally ready to attack the speech recognition functionality.

We are going to do the absolute bare minimum of work to implement this behavior by cramming Speech framework code directly into our model. Longtime viewers of Point-Free will see the problems with this right away, but we want to show this approach as it is how Apple’s Scrumdinger was built, and it will make it easier to see the drawbacks.
