Why it matters
A participant in São Paulo hearing a Brazilian Portuguese moderator is having a different experience than the same participant hearing an American voice.

Global default voices can create friction in interviews—leading to shorter answers, hesitation, and lower completion in markets where the moderator sounds unfamiliar or out of place.

Regional voice and accent support helps interviews feel more natural and localized, improving participant comfort and response quality across global studies.
