+# List All The Say Voices
+
+The `say` command can be a fun party trick.
+
+```bash
+$ say Get ready for the bass to drop
+```
+
+Your friends will be even more impressed when you use some of the alternate
+voices.
+
+```bash
+$ say -v Daniel Would you like a cup of tea?
+```
+
+To see all the alternate voices available, type the following
+
+```bash
+$ say -v '?'
+```
