+Language Support
+----------------
+
+eSpeak supports multiple languages so speak.js can too. To do this, you
+need to build a custom version of speak.js:
+
+ * Bundle the proper language files. For french, you need fr_dict and voices/fr.
+   See commented-out code in emscripten.sh.
+ * Expose those files to the emulated filesystem, in post.js. See commented-out
+   code in there as well.
+ * Run emscripten.sh to build.
+
+You then need to call speak() with the `voice` option that tells it to use the
+right voice for your language. For example, for French this should work:
+
+      `speak('boulanger', { voice: 'fr' })`
