We want the machine learning algorithms to able to handle a variety of background noise, and even relatively loud noises can be accepted provided that they don’t prevent you from hearing the entirety of the text. Quiet background music is OK; music loud enough to prevent you from hearing each and every word is not.
Ri ḓo ṱoḓa uri algorithm dza machine learning dzi kone u fhambanyisa phosho i re nga murahu, na phosho ya khulwane i nga tendela, fhedzi a yo ngo tea u thivhela uri ni pfe zwoṱhe zwo ambiwaho. Muzika u re fhasi wo tendelwa; muzika u ne wa khou ita phosho lune ni si kone u pfa maipfi oṱhe ane muṅwe a khou a amba a wo ngo tendelwa.
