AI calling for voice-based CSAT and NPS surveys

Capture satisfaction scores and verbatim feedback by voice after every service interaction — reaching customers who never click a survey link.

The problem

Post-service link surveys see consistently low response because most customers do not take the time to click and type. Voice surveys reach customers on a channel they already answer, and a spoken answer is richer than a tapped number on a form.

How Vaanicall runs it

  1. Post-service trigger

    After a service event — a delivery, a repair, a clinic visit — upload the relevant contacts as a CSV. The system dials them within your configured window, while the experience is still fresh.

  2. Short voice survey

    The AI agent runs through two to four questions: an overall satisfaction score, a specific experience question, and an open-ended verbatim. Question sequence and wording are set in your agent script.

  3. Scores and verbatims extracted

    Each numeric score and the verbatim answer are extracted as structured fields on the contact record, visible per-contact in the dashboard. The overall disposition (e.g. detractor) is available via GET /v1/calls.

  4. Detractors flagged for callback

    Respondents who give a low score are dispositioned as "detractor" and a callback task is raised for your service team — so every unhappy customer gets a human follow-up.

  4. Customer: Main four dunga. Technician accha tha lekin thoda late aaya.

  5. AI Agent: Shukriya. Aur kya koi cheez hai jo hum better kar sakte hain?

  6. Customer: Bas time ki punctuality theek hoti toh perfect hota.

  • Opt-out honoured mid-call: if a customer says they do not want to participate, the call ends immediately and the contact is flagged as opted-out for future campaigns.
  • TRAI calling window: all outbound calls dial only within 09:00–21:00 IST.

Questions, answered

Response rates vary by industry, timing, and how well-known your brand is to the customer — we do not quote a number. What we can say is that voice surveys consistently outperform link-based surveys in Indian markets because customers are more accustomed to picking up a call than clicking a link. Your results will depend on your specific audience and call cadence.
