Glossary

15.ai was a freeware artificial intelligence web application that generated text-to-speech voices from fictional characters from various media sources.[5][6][7][8] Created by a pseudonymous developer under the alias 15,[1][2][3][4][9] the project used a combination of audio synthesis algorithms, speech synthesis deep neural networks, and sentiment analysis models to generate emotive character voices faster than real-time.[a][10][11]

In early 2020, 15.ai appeared online as a proof of concept of the democratization of voice acting and dubbing.[9][12] Its gratis nature, ease of use without user accounts, and improvements over existing text-to-speech implementations made it popular.[6][5][7] Some critics and voice actors questioned the legality and ethicality of making such technology so readily accessible.[13]

The site was credited as the impetus behind the popularization of AI voice cloning (also known as audio deepfakes) in content creation.[2][9] It was embraced by Internet fandoms such as My Little Pony, Team Fortress 2, and SpongeBob SquarePants.[1][14][9]

Several commercial alternatives appeared in the following years.[2][3][4] In January 2022, the company Voiceverse NFT plagiarized 15.ai's work as part of their platform.[15][16][17]

In September 2022, a year after its last stable release, 15.ai was taken offline.[3][2] As of November 2024, the website was still offline, with the creator's most recent post being dated February 2023.[18]

Features

HAL 9000, known for his sinister robotic voice, is one of the available characters on 15.ai.[5]

The platform required no user registration or account creation to generate voices.[2][4][9] Users could generate speech by entering text and selecting a character voice (optionally specifying an emotional contextualizer and/or phonetic transcriptions), with the system producing three variations of the audio with different emotional deliveries.[10] The platform operated completely free of charge, though the developer reported spending thousands of dollars monthly to maintain the service.[9]

Available characters included GLaDOS and Wheatley from Portal, characters from Team Fortress 2, Twilight Sparkle and other characters from My Little Pony: Friendship Is Magic, SpongeBob, Daria Morgendorffer and Jane Lane from Daria, the Tenth Doctor Who, HAL 9000 from 2001: A Space Odyssey, the Narrator from The Stanley Parable, Carl Brutananadilewski from Aqua Teen Hunger Force, Steven Universe, Dan from Dan Vs., and Sans from Undertale.[14][1][19][20]

The nondeterministic nature of the deep learning model ensured that each generation would have slightly different intonations, similar to multiple takes from a voice actor.[10][1] The application supported manually altering the emotion of a generated line using emotional contextualizers (a term coined by this project), a sentence or phrase conveying the emotion of the take that serves as a guide for the model during inference.[1][14] Emotional contextualizers were representations of the emotional content of a sentence deduced via transfer learned emoji embeddings using DeepMoji, a deep neural network sentiment analysis algorithm developed by the MIT Media Lab in 2017.[21][22] DeepMoji was trained on 1.2 billion emoji occurrences in Twitter data from 2013 to 2017, and outperformed human subjects in correctly identifying sarcasm in Tweets and other online modes of communication.[23][24][25]

15.ai used a multi-speaker model—hundreds of voices were trained concurrently rather than sequentially, decreasing the required training time and enabling the model to learn and generalize shared emotional context, even for voices with no exposure to that context.[26][2] Consequently, the characters in the application were powered by a single trained model, as opposed to multiple single-speaker models.[27] The lexicon used by 15.ai was scraped from a variety of Internet sources, including Oxford Dictionaries, Wiktionary, the CMU Pronouncing Dictionary, 4chan, Reddit, and Twitter. Pronunciations of unfamiliar words were automatically deduced using phonological rules learned by the deep learning model.[1]

The application supported a simplified phonetic transcription known as ARPABET, to correct mispronunciations and account for heteronyms—words that are spelled the same but are pronounced differently (such as the word read, which can be pronounced as either /ˈrɛd/ or /ˈriːd/ depending on its tense). It followed the CMU Pronouncing Dictionary's ARPABET conventions.[1]

Background

Speech synthesis

Main article: Deep learning speech synthesis
See also: Audio deepfake
A stack of dilated casual convolutional layers used in DeepMind's WaveNet.[28]

In 2016, with the proposal of DeepMind's WaveNet, deep-learning-based models for speech synthesis began to gain popularity as a method of modeling waveforms and generating high-fidelity human-like speech.[29][30][28] Tacotron2, a neural network architecture for speech synthesis developed by Google AI, was published in 2018 and required tens of hours of audio data to produce intelligible speech; when trained on 2 hours of speech, the model was able to produce intelligible speech with mediocre quality, and when trained on 36 minutes of speech, the model was unable to produce intelligible speech.[31][32]

For years, reducing the amount of data required to train a realistic high-quality text-to-speech model has been a primary goal of scientific researchers in the field of deep learning speech synthesis.[33][34] The developer of 15.ai claims that as little as 15 seconds of data is sufficient to clone a voice up to human standards, a significant reduction in the amount of data required.[35]

Copyrighted material in deep learning

Main article: Authors Guild, Inc. v. Google, Inc.

A landmark case between Google and the Authors Guild in 2013 ruled that Google Books—a service that searches the full text of printed copyrighted books—was transformative, thus meeting all requirements for fair use.[36] This case set an important legal precedent for the field of deep learning and artificial intelligence: using copyrighted material to train a discriminative model or a non-commercial generative model was deemed legal. The legality of commercial generative models trained using copyrighted material is still under debate; due to the black-box nature of machine learning models, any allegations of copyright infringement via direct competition would be difficult to prove.[37]

Development

15.ai was designed and created by an anonymous research scientist known by the alias 15.[1][2][3][4] Developing and running 15.ai cost several thousands of dollars per month, initially funded by the developer's personal finances after a successful startup exit.[9]

The algorithm used by the project was dubbed DeepThroat.[9][38] The developer said the project and algorithm were conceived as part of MIT's Undergraduate Research Opportunities Program, and had been in development for years before the first release of the application.[1][39]

The Pony Preservation Project from 4chan's /mlp/ board has been integral to the development of 15.ai.[40]

The developer also worked closely with the Pony Preservation Project from /mlp/, the My Little Pony board of 4chan.[9] This project was a "collaborative effort by /mlp/ to build and curate pony datasets" with the aim of creating applications in artificial intelligence.[41][42] The Friendship Is Magic voices on 15.ai were trained on a large dataset crowdsourced by the project: audio and dialogue from the show and related media[9]—including all nine seasons of Friendship Is Magic, the 2017 movie, spinoffs, leaks, and various other content voiced by the same voice actors—were parsed, hand-transcribed, and processed to remove background noise.

Reception

15.ai was met with a largely positive reception. Liana Ruppert of Game Informer described it as "simplistically brilliant"[6] and José Villalobos of LaPS4 wrote that it "works as easy as it looks."[19][b] Lauren Morton of Rock, Paper, Shotgun called the tool "fascinating,"[8] and Yuki Kurosawa of AUTOMATON deemed it "revolutionary."[1][c] Users praised the ability to easily create audio of popular characters that sound believable to those unaware they had been synthesized. Zack Zwiezen of Kotaku reported that "[his] girlfriend was convinced it was a new voice line from GLaDOS' voice actor, Ellen McLain".[5]

Impact

Fandom content creation

15.ai was frequently used for content creation in various fandoms, including the My Little Pony: Friendship Is Magic fandom, the Team Fortress 2 fandom, the Portal fandom, and the SpongeBob SquarePants fandom, with numerous videos and projects containing speech from 15.ai having gone viral.[5][6] The platform is credited as the impetus behind the popularization of AI voice cloning in content creation, demonstrating the potential for accessible, high-quality voice synthesis technology.[2][9]

The My Little Pony: Friendship Is Magic fandom saw a resurgence in video and musical content creation as a result, inspiring a new genre of fan-created content assisted by artificial intelligence. Some fanfictions weren adapted into fully voiced "episodes": The Tax Breaks is a 17-minute long animated video rendition of a fan-written story published in 2014 that uses voices generated from 15.ai with sound effects and audio editing, emulating the episodic style of the early seasons of Friendship Is Magic.[43][44]

Viral videos from the Team Fortress 2 fandom featuring voices from 15.ai include Spy is a Furry (which gained over 3 million views on YouTube across multiple videos[yt 1][yt 2][yt 3]) and The RED Bread Bank, both of which inspired Source Filmmaker animated video renditions.[1] Other fandoms used voices from 15.ai to produce viral videos. As of July 2022, the viral video Among Us Struggles (with voices from Friendship Is Magic) had over 5.5 million views on YouTube;[yt 4] YouTubers, TikTokers, and Twitch streamers also used 15.ai for their videos, such as FitMC's video on the history of 2b2t—one of the oldest running Minecraft servers—and datpon3's TikTok video featuring the main characters of Friendship Is Magic, which have 1.4 million and 510 thousand views, respectively.[yt 5][tt 1]

Some users created AI virtual assistants using 15.ai and external voice control software. One user on Twitter created a personal desktop assistant inspired by GLaDOS using 15.ai-generated dialogue in tandem with voice control system VoiceAttack.[1][14]

I’m partnering with @VoiceverseNFT to explore ways where together we might bring new tools to new creators to make new things, and allow everyone a chance to own & invest in the IP’s they create. We all have a story to tell. You can hate. Or you can create. What'll it be?

January 14, 2022[tweet 1]

In December 2021, the developer of 15.ai posted on Twitter that they had no interest in incorporating non-fungible tokens (NFTs) into their work.[13][16][tweet 2]

On January 14, 2022, it was discovered that Voiceverse NFT, a company that video game and anime dub voice actor Troy Baker announced his partnership with, had plagiarized voice lines generated from 15.ai as part of their marketing campaign.[15][16][17] Log files showed that Voiceverse had generated audio of Twilight Sparkle and Rainbow Dash from the show My Little Pony: Friendship Is Magic using 15.ai, pitched them up to make them sound unrecognizable from the original voices, and appropriated them without credit, to falsely market their own platform—in violation of 15.ai's terms of service.[35][13][17]

I've been informed that the aforementioned NFT vocal synthesis is actively attempting to appropriate my work for their own benefit. After digging through the log files, I have evidence that some of the voices that they are taking credit for were indeed generated from my own site.

Hey @fifteenai we are extremely sorry about this. The voice was indeed taken from your platform, which our marketing team used without giving proper credit. Chubbiverse team has no knowledge of this. We will make sure this never happens again.

Go fuck yourself.

January 14, 2022[tweet 5]

A week prior to the announcement of the partnership with Baker, Voiceverse made a (now-deleted) Twitter post directly responding to a (now-deleted) video posted by Chubbiverse—an NFT platform with which Voiceverse had partnered—showcasing an AI-generated voice and claimed that it was generated using Voiceverse's platform, remarking "I wonder who created the voice for this? ;)"[15][tweet 6] A few hours after news of the partnership broke, the developer of 15.ai—having been alerted by another Twitter user asking for his opinion on the partnership, to which he speculated that it "sounds like a scam"[tweet 7]—posted screenshots of log files that proved that a user of the website (with their IP address redacted) had submitted inputs of the exact words spoken by the AI voice in the video posted by Chubbiverse,[tweet 8] and subsequently responded to Voiceverse's claim directly, tweeting "Certainly not you :)".[35][16][tweet 9]

Following the tweet, Voiceverse admitted to plagiarizing voices from 15.ai as their own platform, claiming that their marketing team had used the project without giving proper credit and that the "Chubbiverse team [had] no knowledge of this." In response to the admission, 15 tweeted "Go fuck yourself."[15][16][17][35] The final tweet went viral, accruing over 75,000 total likes and 13,000 total retweets across multiple reposts.[tweet 10][tweet 11][tweet 12]

The initial partnership between Baker and Voiceverse was met with severe backlash and universally negative reception.[15] Critics highlighted the environmental impact of and potential for exit scams associated with NFT sales.[45] Commentators also pointed out the irony in Baker's initial Tweet announcing the partnership, which ended with "You can hate. Or you can create. What'll it be?", hours before the public revelation that the company in question had resorted to theft instead of creating their own product. Baker responded that he appreciated people sharing their thoughts and their responses were "giving [him] a lot to think about,"[46][47] and asked fans on social media to forgive him.[16][48] Two weeks later, Baker discontinued his partnership with Voiceverse.[49][50]

Impact on voice cloning technology

15.ai introduced several technical innovations in voice cloning. While traditional text-to-speech systems like Google's Tacotron2 required tens of hours of audio data to produce intelligible speech in 2017,[31][32] 15.ai claimed to achieve high-quality voice cloning with as little as 15 seconds of training data.[35][9] This reduction in required training data represented a breakthrough in the field of speech synthesis.[10][9]

The project also introduced the concept of "emotional contextualizers" for controlling speech emotion through sentiment analysis.[1][14][10]

Reactions from voice actors

Some voice actors have publicly decried the use of voice cloning technology. Cited reasons include concerns about copyright infringement, right to privacy, impersonation and fraud, unauthorized use of an actor's voice in pornography or explicit content, and the potential of AI being used to make voice actors obsolete.[3][13][9][10]

  1. ^ The term "faster than real-time" in speech synthesis means that the system can generate audio more quickly than the actual duration of the speech – for example, generating 10 seconds of speech in less than 10 seconds would be considered faster than real-time.
  2. ^ Translated from original quote written in Spanish: "La dirección es 15.AI y funciona tan fácil como parece."[19]
  3. ^ Translated from original quote written in Japanese: "しかし15.aiが画期的なのは「データが30秒しかない文字でも、ほぼ100％の発音精度を達成できること」そして「ごくわずかなデータのみを使って、自然な感情のこもった音声を数百以上生成できること」だという。"[1]
