And better yet, how can you record it in OSX?

[red rocket]

You can use Terminal.app.

[codex]SAY(1) Speech Synthesis Manager SAY(1)

NAME
say - Convert text to audible speech

SYNOPSIS
say [-v voice] [-o out.aiff] [-f file | string ...]

DESCRIPTION
This tool uses the Speech Synthesis manager to convert input text to
audible speech and either play it through the sound output device cho-
sen in System Preferences or save it to an AIFF file.

OPTIONS
string
Specify the text to speak on the command line. This can consist of
multiple arguments, which are considered to be separated by spaces.

-f file
Specify a file to be spoken. If file is - or neither this parameter
nor a message is specified, read from standard input.

-v voice
Specify the voice to be used. Default is the voice selected in Sys-
tem Preferences.

-o out.aiff
Specify an AIFF file to be written.

If the input is a TTY, text is spoken line by line, and the output
file, if specified, will only contain audio for the last line of the
input. Otherwise, text is spoken all at once.[/codex]

Or, you could just highlight what you want spoken, right click, and go to the "speech" menu...

For recording, Terminal seems the only OS X built in way...

AppleScript is the easiest way to record speech in OS X.

Thank you!

Highlight the text you want read (or hit Command-A to highlight everything). Go to the App's menu -> Services -> Speech -> Start Speaking Text

This only seems to work in Cocoa apps.

Doesn't record, though, which the applescript linked to above does.

I find the speech recognition works a bit better if you set the font size above 11 and choose a more readable font like Times New Roman. im only joking!
