In 1990, the first research paper regarding Golden Speakers came out proving their efficacy in helping individuals build native-like accent in a target foreign language. A "Golden Speaker" refers to another person with proper pronunciation but a similar voice identity.
With today's technology, a user's "Golden Speaker" can be generated-> You record yourself saying a sentence (which would be a phonetic pangram), we keep your accent which represents your voice identity but we correct your pronunciation and then you have a Golden Speaker system. This may be in the form of a TTS or a real-time accent conversion technology.
furthermore, if you would like to get early access to a real-time accent conversion technology to be able to go from Point A (foreign accent) to B (native-like accent) faster, you can sign up at loxai.tech.
would very much appreciate input on this idea especially from those in AI and linguistics
