LOR.pth

**LOR.pth** is an incomplete AI voice model that mimics Randy Crenshaw's Lorax, as heard in the scrapped 2012 Lorax movie song, "Biggering".

Its intended use was for The Biggering-related projects; and represent The Lorax, possibly after having been fused with another model.

LOR's creation started at the beginning of August, 2023, but progress was aborted later that month when Google Colab reinforced its rules on "disallowed code"; and made it no longer possible to freely train AI models through means of the RVC-Project web UI or similar Colab templates.

There's no certainty on whether LOR can or will be revisited.

## Technical details

LOR was assembled through a Colab-hosted Python script, known as the RVC-Project, on standard 40k settings. The first model was trained with only 25 seconds of audio, solely extracted from "Biggering".

With no other examples of the voice available online, the audio library was increased with help of the model itself; and songs performed by LOR were used to teach the next model. In order to maintain the character's New Yorker accent, LOR also redubbed the entirety of the Danny DeVito AI's audio library. Mispronounced words were cut out or fixed in editing, trying to help LOR speak properly. Around 6 minutes of total usable footage was left to train with.

All audio files were exported in MP3 format -opposed to the often recommended, but heavier WAV.

### Used data

* "Biggering" by The 88 (speech extraction)
* Test performances by an earlier version of the model, fed back to it:
	+ Danny Devito AI's audio library
	+ "iPad" by Parry Gripp
	+ "Help the People" by Birdy
	+ "Burning Stuntman" by Golden Earring
	+ "Family of Me" by Ben Folds
	+ "Nobody Needs a Thneed" (first recorded demo)

### Voice description

LOR sounds like a parody of Randy Crenshaw's Lorax; with its higher pitch and subdued roughness, yet is relatively coherent, considering the small quantity of footage it was given to work with. Even so, by borrowing Danny DeVito AI's audio library, it shares its faults, and in addition slurs his speech.

It has a robotic sound that's not too noticeable at times, but worsens when a voice's volume or tone gets too low. Generally, its sound quality is clear and decent for song mixing, though of lower quality than that of, for example, the common animation studio.

Like AI models in general at this stage (2023), it can't properly copy tracks with strong echo in them, vocals with background singers performing at the same time, or group performances/overtone singing. Occasionally, it may circumvent it, but tends to break again when the pitch strays from the average or there's a long note.

If the original singer has a particular accent, it will try to copy it, though the model's speech impediment remains strongly present. Since Crenshaw is an American-English speaker, the model sings foreign songs with an accent.

On the flip side, foreigners with a slight accent sound more American when they speak English through LOR, unless their accent is especially strong.

### LOR

"LOR", or "DemoLorax", is an unfinished 200 epoch model that was still in its starting phase when Colab reinforced their rules. It's not considered useable at this time.

## Trivia

* LOR is VampireMeerkat's third attempt at voice cloning.
* With there being little to no (recent) online fuss about the code restriction that prevents further development on GM, the possibility exists that the real problem concerns something Google Colab refuses to specify and is specific to VampireMeerkat.
