Voice of the customer (VoC): meaning, methods and examples

What is voice of the customer (VoC)?

Voice of the customer is the practice of capturing what customers say about their needs, experiences and frustrations, in their own words, and feeding it into product, service and marketing decisions.

Voice of the customer methods

  • Surveys, including open-text questions.
  • Interviews and customer advisory groups.
  • Support tickets, chats and call notes.
  • Reviews, community posts and social mentions.
  • Sales call notes and lost-deal reasons.

Voice of the customer examples

  • Support tickets show complaints about exports doubled after a release, so the fix jumps the roadmap.
  • Interviews reveal customers buy for audit readiness, not speed, and the homepage message changes.
  • Lost-deal notes show per-user pricing is the main objection, so a team plan is tested.

Running a VoC program

Collect continuously rather than in one annual survey, tie each insight to someone who owns the decision, and close the loop by telling customers what changed. Common VoC data sources include support conversations, which are unusually honest because people write them when something matters to them.

Support conversations as VoC data

Customer Support Sentiment Analyzer reads support conversations for sentiment, emotion and topics, which turns the busiest source of customer feedback most companies already have into something they can act on.

  • Topic clustering — Topic clustering groups customer conversations by what they are about, such as billing, login problems or a specific feature, so sentiment and volume can be traced to a cause instead of reported as one average.
  • Sentiment analysis — Sentiment analysis classifies text by the attitude it expresses, usually positive, negative or neutral, and ideally by how strongly, so large volumes of reviews, tickets or comments can be read at a glance.
  • Churn risk — Churn risk is the likelihood that a customer will leave.
