(Thanks to Marco Gulino for this nice hint!)
This page shows how to configure Ubuntu for "emulating" MacOs say command, in order to use Cruise-monitor on Ubuntu.
Install Festival
First step is installing festival, a general purpose text-to-speech system. We'll also need to install a voice, which doesn't get installed with festival by default. We'll use festvox-don.
Open a terminal in Ubuntu and type:
sudo apt-get install festival festvox-don
You should now be able to run it; test it with:
echo hello | festival --tts
For any other info or troubles installing festival on Ubuntu, please refer to the official page.
Create say script
We can now wrap festival with a shell script, emulating MacOs say command. Save this script file in /usr/bin/say:
#!/bin/bash
echo "$@" | festival --tts
It should now be into PATH. Test it with:
say hello world!
That's all: we should now be able to use Cruise-monitor on Ubuntu too!
See this FiveMinutesTutorial for installing, configuring and running Cruise-monitor.
