# ListenLand FAQ: Interviews, Voice Mode, and Webhooks

> Quick answers about ListenLand interviews, voice mode, transcripts, webhooks, and more — everything you need to get the most out of the platform.

Find quick answers to the most common questions about ListenLand below.

<AccordionGroup>
  <Accordion title="Do respondents need a ListenLand account?">
    No. Respondents never need to sign up or download anything. You share a link, they open it, and their conversation begins immediately in the browser. There's no friction between your research question and a completed response.
  </Accordion>

  <Accordion title="How long can a conversation last?">
    Conversations have a hard limit of **20 minutes**. As the limit approaches, the AI interviewer will naturally bring the conversation to a close rather than cutting off abruptly. This cap keeps costs predictable and encourages focused, high-quality responses.
  </Accordion>

  <Accordion title="What's the difference between text and voice mode?">
    * **Text mode:** Respondents type their answers and the AI replies in text — similar to a chat interface. Every exchange is captured in a full transcript.
    * **Voice mode:** Respondents speak and the AI replies in spoken audio using a low-latency connection. This mode feels more like a natural conversation and can surface more candid responses. Both modes produce a complete text transcript.

    The interview owner sets a default mode, but respondents can toggle between modes on the conversation page if they prefer.
  </Accordion>

  <Accordion title="Can I change questions after publishing?">
    Yes. You can edit your questions and interview overview at any time. However, **changes only apply to future conversations** — responses that have already been completed won't be retroactively re-analyzed against the updated questions.
  </Accordion>

  <Accordion title="How does the AI know what follow-up questions to ask?">
    You set a **follow-up depth** — Low, Medium, or High — for each question when building your interview. The AI uses this setting, combined with your interview overview and what the respondent has said so far, to generate contextual follow-up questions dynamically. A richer overview gives the AI more context to probe meaningfully.
  </Accordion>

  <Accordion title="Can I customize the AI's personality or tone?">
    Yes. The **Persona Instructions** field in your interview settings lets you give the AI specific guidance about how it should conduct the conversation. For example:

    * *"Be concise and direct — keep your turns short."*
    * *"Use a friendly, casual tone. Avoid corporate jargon."*
    * *"You are a senior UX researcher. Ask probing, empathetic questions."*

    These instructions apply to every conversation within that interview.
  </Accordion>

  <Accordion title="What languages are supported?">
    You can set any language in the interview settings, and the AI will conduct the entire conversation in that language — questions, follow-ups, and summary alike. Both text and voice modes respect this setting. Most major world languages are supported; if you're unsure whether a specific language will work well, run a quick test conversation before sharing your interview broadly.
  </Accordion>

  <Accordion title="Are audio recordings available for text-mode interviews?">
    Audio recordings are generated for **voice-mode conversations** only, where the respondent speaks and the AI responds with synthesized audio. Text-mode interviews produce full transcripts of every exchange, but no audio file. If audio recordings are important to your workflow, set voice as the default mode for your interview.
  </Accordion>

  <Accordion title="Can I share individual conversation transcripts with stakeholders?">
    Yes. Enable **Public Conversations** on the interview's settings page. Once enabled, each completed conversation gets its own unique, shareable URL that anyone can view — no ListenLand account required. You can share a specific transcript without granting access to your entire dashboard.
  </Accordion>

  <Accordion title="How do I get notified when someone completes an interview?">
    Set up a **webhook** on the interview's integrations page. When a conversation is completed, ListenLand sends a signed `conversation.completed` HTTP POST to your endpoint containing the transcript, summary, and metadata. See the [Webhooks](/integrations/webhooks) documentation for the full payload reference and signature verification guide.
  </Accordion>

  <Accordion title="Can I delete a response?">
    Yes. Open the conversation from your dashboard and use the delete option. **Deletion is permanent** — the transcript, AI summary, and any associated audio files are removed immediately and cannot be recovered. Make sure you've exported anything you need before deleting.
  </Accordion>

  <Accordion title="What browsers does voice mode support?">
    Voice mode uses **WebRTC** and requires a modern desktop or mobile browser:

    | Browser | Minimum Version |
    | ------- | --------------- |
    | Chrome  | 90+             |
    | Firefox | 90+             |
    | Safari  | 17+             |

    Respondents must also **grant microphone permission** when prompted. If a respondent's browser doesn't support WebRTC, they can switch to text mode and still complete the interview.
