What the Multi-lingual Voice Interviewer Does

When you allow voice readout, participants can switch on read-aloud at the start of the interview and hear each question. Read-aloud is off for each participant until they turn it on. This makes interviews more accessible and conversational, particularly valuable for:
  • Markets where reading in a second language creates fatigue
  • Older audiences or those with lower literacy rates
  • Mobile studies where audio-first feels more natural than reading
  • Studies designed to feel like a natural conversation rather than a questionnaire

​
Choosing a Language and Voice

Listen offers multiple voice options for each of the 42 supported languages. Voices vary in tone, pacing, and regional accent — so you can choose one that feels authentic for your target audience. (Note: Voice audio is separate from Auto-Translations, which covers 120+ languages for text-based interviews.)

​

Voice vs. Text Interviewer

You can use voice and text interchangeably per study, or set a study-wide default. Text tends to work better for B2B and professional audiences; voice performs better for consumer research, mobile-first studies, and international markets where reading in a second language is a barrier.
