Version Control of Speaker Recognition Systems

Wang, Quan, Moreno, Ignacio Lopez

Understand

This paper discusses one of the most challenging practical engineering problems in speaker recognition systems - the version control of models and user profiles.

  • A typical speaker recognition system consists of two stages: the enrollment stage, where a profile is generated from user-provided enrollment audio; and the runtime stage, where the voice identity of the runtime audio is compared against the stored profiles.
  • As technology advances, the speaker recognition system needs to be updated for better performance.
  • However, if the stored user profiles are not updated accordingly, version mismatch will result in meaningless recognition results.
