computer generated text-to-speech

Does it comply with the Librivox mission statement for someone to run Gutenberg (or any PD) texts through a Text-to-Speech program and upload them to Librivox? Or do sections have to be recorded by an actual person? I ask this because some sections I have listened to definitely sound computer generated. Is there any way to test this?

No, it is not LV's mission to use computer generated voices. We use real people, even some that speak somewhat robotically.

But it is a good question. Can a suspicious file be tested to see if it is a text-to-speech generated file? It would be tragic if all our personal efforts could be thwarted by computer generated audio files. Is there anything in our mission statement deterring that?

The mission statement is definitely people not computers - but we do have to trust our readers. There are couple of readers with an unusual sound but they do breathe.

I am delighted to hear that LV does not condone computer generated files.
Suppose that some files are found whose contents *ARE* convincingly "synthetic".
What would be done about them? And with the person who tried to pawn them off a "real" voice recordings?
Is there a policy for that situation?

-- just curious

How would we prove it? And what would someone gain by generating them and giving them away ?

I can envision an unfortunate soul of diminished self-worth who would like to brag that he has had over 400 items accepted on LibriVox. "His ego makes him do it!"

Or, more kindly, I can envision a throat cancer survivor who is able to "talk" only with the use of an electronic larynx. These devices work by emitting a square-wave "carrier" tone (a buzz sound) and then modulating it with what's left of any vocal chords. That ever present monotone BUZZ tone is one give away that an electronic device is producing the words.

Lastly, I can envision a reader who is bored silly by the proofing and editing process for their recorded files. If he let's the computer do it, then it will be "word perfect" every time, you see. A lot of meaning of the text normally imparted thru intonation and inflection will be totally lost; the rhyming of poems would be hardly noticeable, but every single word will have been included as written.

A last comment: I asked Mr. Google what free programs or websites were available to produce speech files from text files (Text-to-Speech).
I found 84 of them. And, these were the FREE sources.

I am delighted that a friend turned me on to Librivox. I am spreading the word like crazy among all my friends. Keep up the good work!

Does LibriVox discriminate against zombies?

Not as such, I don't think. It's just that there aren't many books out there that are made up completely of moans and/or the word "braaaaains"...

Well... But then again, PP & Zombies won't be PD for a long time to come. Would make a great DR, I'm sure.
