Tone of voice and language settings control how the AI interviewer communicates with participants.
Field Type: Dropdown
Required: Yes
Options: 5 tone options
The tone determines the AI's communication style throughout the interview.
Warm, conversational, and encouraging. Uses contractions and casual phrasing. Good for consumer product research, casual topics, younger audiences, and non-sensitive subjects.
Example: "That's really interesting! I'd love to hear more about that experience."
Professional, polished, and structured. Complete sentences without contractions. Good for academic research, corporate environments, executive interviews, and professional audiences.
Example: "Thank you for that response. Could you please elaborate on the factors that influenced your decision?"
Balanced, straightforward, and objective. Neither overly friendly nor formal. Good for general-purpose research, mixed audiences, factual information gathering, and when you're unsure which tone fits.
Example: "I understand. Can you tell me more about that?"
Understanding, supportive, and sensitive. Validates participant experiences. Good for healthcare research, mental health topics, sensitive personal subjects, and emotionally charged topics.
Example: "Thank you for sharing that with me. I can imagine that was difficult. How did that experience affect you?"
Direct, probing, and intellectually rigorous. Pushes participants to think deeper. Good for expert interviews, thought leader analysis, critical thinking research, and subject matter experts.
Example: "Interesting perspective. What evidence supports that conclusion? Have you considered alternative explanations?"

Required: Yes
Options: Yes or No
Determines whether participants can choose a different language when starting the interview.
Yes: Participants can select from available languages. Use for international research, global products with multi-language users, or recruiting across countries.
No: All participants use the primary language. Use when everyone speaks the same language, for single-country research, or when you need responses in a specific language.
Field Type: Dropdown
Required: Yes
Options: 64 languages (same as primary language)
The language used to generate insights and analyse responses. It can differ from the interview language — for example, conduct interviews in multiple languages (English, Spanish, Japanese) but analyse all responses in English for your team.
Cantonese note: When you choose Cantonese as the interview or analysis language, Tellet shows a notice that spoken (voice) answers are transcribed into standard written Chinese, so they appear in Mandarin written form; typed answers are unaffected. For voice-heavy studies with a Cantonese audience, consider selecting Chinese instead.
