Unfortunately "say" behaves differently depending on whether its stdin is
attached to a tty or not (and there's no cmd line option to prevent this).
With the former it'll speak after every newline, with the latter not until

gets an EOF and I'd rather not do a fork-exec for each individual word or
phrase that needs to be spoken.

Sounds a little bit hacky but I'll have a look at it, cheers.
