Compiles input files written in a simple, custom DSL to MP3 audio files. Currently only works on Mac OS X. I use these files to power a physical computing project based on Raspberry PI that plays the audio and collects user input through push buttons (like a simple modern Speak 'N Spell).
Install Clojure, Leiningen, and Lame.
$ brew install clojure leiningen lame
$ lein do clean, run [voice] [question bank]
Each question from the question bank will be compiled to an MP3 file in a
subfolder corresponding to the correct answer under the target directory.
[voice]- the name of an installed Voice Over voice (defaults to Samanth)[rate]- the rate at which the voice should speak (defaults to 30)[question bank]- the name (minus extension) of a file under resources/input to compile (defaults to electrical-engineering).
Run say -v '?' at the command line to see installed voices.
Tip: I've found slowing the speech rate to 33 in the Voice Over utility sounds better than the default setting.
The input source is a plain text file containing a question on one line,
followed by multiple answers. Each of the answers must begin with either a +,
which denotes the correct answer, or a - which denotes an incorrect answer.
Questions must be separated by one or more blank lines.
