Voxmind’s phoneme extraction model (XLSR-300M) was trained across 128 languages, making the core voice biometrics engine genuinely language-agnostic. This means a user can enroll in one language and authenticate in another — the voiceprint captures anatomical constants that don’t change with language. TheDocumentation Index

language parameter on enrollment and verification calls helps the phoneme segmentation model apply the correct acoustic boundaries for the submitted audio. It’s optional (defaulting to en-UK) but specifying the correct language improves accuracy, particularly for languages with phoneme inventories that differ significantly from English.
