1. An authentication system for impaired voice authentication, the system comprising;
at least one processor; and
memory including instructions that, when executed by the at least one processor, cause the at least one processor to perform operations to:
retrieve an initial voice profile for a user;
generate an alternate voice profile by passing the initial voice profile through a voice filter;
transmit an inaudible audio tone pattern to a device of the user;
receive an audio stream including an authentication voice data of the user; and
authenticate the user based on a match of the authentication voice data with a portion of a first set of authentication criteria and based on detection of the inaudible audio tone pattern in the audio stream, the first set of authentication criteria including acoustic features of the initial voice profile and acoustic features of the alternate voice profile.
