Why Voiceprints Are Not an Interoperable File Format

Voice biometrics often promises portable voiceprints, yet no vendor-neutral standard exists to exchange speaker models. The official ISO/IEC 19794-13 biometrics standard deliberately covers only raw audio packaging, leaving extraction and speaker embeddings outside its scope due to vendor trade secrets. Looking at efforts like Brno University of Technology's Voice Biometry Standardization Initiative reveals the underlying technical friction: cross-system use requires identical frozen checkpoints, and transferring representations across different extraction pipelines demands training custom pairwise regression bridges.
