MAC's “say” command to MP3 [closed]

Question

I want to read a very long text with the SAY mac's command (say -f file.txt), and to record the output to file.mp3. I thought about using ffmpeg to record all of it, but then i'll need to wait for all the reading process to complete..

I don't really need to listen to it, so if there is a way to directly have an mp3 file just by hitting enter, it would be great..

There is also this project txt2mp3mac but i can't use it in a shell script..

Thanks..

Update

Check this gist for a script that does it

Answer 1

I'm not on a Mac right now, so I can't test, but this page suggests you can do

say -f script.txt -o greetings.aiff

to load what should be said from script.txt and save the audio output as greetings.aiff. You can then convert it to mp3 using lame with

lame -m m greetings.aiff greetings.mp3

Definitely try the different voices. :D
