Speech synthesis is the artificial production of human speech. A computer system used for this purpose is called a "speech computer" or "speech synthesizer," and can be implemented in software or hardware products. A text-to-speech (TTS) system converts normal language text into speech; other systems render symbolic linguistic representations like phonetic transcriptions into speech.
Synthesized speech can be created by concatenating pieces of recorded speech that are stored in a database. A system that stores phones or diphones provides the largest output range, but may lack clarity. Alternatively, a synthesizer can incorporate a model of the vocal tract and other human voice characteristics to create a completely "synthetic" voice output.
Deepfakes (a portmanteau of "deep learning" and "fake") are synthetic media in which a person in an image or video is replaced with someone else's likeness. While the act of faking content is not new, deepfakes leverage powerful techniques from machine learning and artificial intelligence to generate visual and audio content with a high potential to deceive.
15.ai is a freeware artificial intelligence web application that generates natural, emotive, high-quality text-to-speech voices from an assortment of fictional characters. The project began development while the developer was an undergraduate at MIT. It uses a combination of audio synthesis algorithms, speech synthesis deep neural networks, and sentiment analysis models to generate and serve emotive character voices faster than in real-time.
Visit the company's website and enter the source, character, and emotion. Add the text you would like converted to audio (a maximum of 200 characters). Hit "Play" to hear your audio or "Download Link" to save your voice clone clip.
15.ai voice cloning is an online program that turns the text you input into audio clips using the voices of beloved characters. The characters on the program are subject to change, but some of the users of the voice have been able to choose from including characters from Rick and Morty, My Little Pony, Spongebob SquarePants, and more.
GLaDOS and Wheatley from Portal, Twilight Sparkle from My Little Pony: Friendship is Magic, SpongeBob from SpongeBob SquarePants, Daria Morgendorffer and Jane Lane from Daria, HAL 9000 from 2001: A Space Odyssey, The Stanley Parable, Super Smash Bros Announcer (formerly), and Sans from Undertale are among the characters available.
