Tracking the right metrics is the difference between a feedback program that drives improvement and one that collects data nobody uses. Voice feedback generates rich, multi-dimensional data, and knowing which metrics matter -- and at which stage of your program -- keeps your team focused on insights that lead to action.
Collection Metrics
These metrics tell you whether your feedback program is reaching the right people and generating enough data to draw meaningful conclusions.
Response Volume
The total number of voice messages received per period (daily, weekly, monthly). This is your most basic health check. Low volume means either poor awareness, bad placement, or lack of trust. Track volume by channel to identify which touchpoints are performing best. Compare against our placement guide benchmarks.
Response Rate
The percentage of people exposed to the feedback opportunity who actually leave a message. Calculate this by dividing message volume by foot traffic, transactions, or employee count. Healthy response rates for voice feedback range from 3 to 8% for customer channels and 10 to 25% for employee channels.
Completion Rate
The percentage of people who start a voice recording and finish it. A low completion rate suggests friction in the recording experience -- perhaps the interface is confusing, the prompt is unclear, or the recording time limit is too short.
Average Message Length
Longer messages generally contain richer insights. Track average recording duration over time. If message length is declining, it could indicate survey fatigue, unclear prompts, or a shift in the type of feedback people are sharing.
Sentiment Metrics
These metrics reveal the emotional landscape of your feedback and how it changes over time.
Average Sentiment Score
The mean sentiment score across all messages in a period. Track this weekly and monthly. A rising trend indicates improvement; a declining trend signals emerging problems. Benchmark your starting score and set targets for improvement.
Sentiment Distribution
The percentage of messages that fall into positive, neutral, and negative categories. A healthy distribution shifts over time as you act on feedback. Watch for changes in the proportion of negative messages -- even if the average score is stable, an increasing percentage of negative messages is a warning sign.
Sentiment by Channel
Compare sentiment scores across different feedback channels (locations, touchpoints, departments). This reveals which parts of your operation are performing well and which need attention. Significant disparities between channels indicate localized issues rather than systemic ones.
Sentiment Volatility
How much does your daily sentiment score vary? High volatility (large swings between days) suggests inconsistent experiences. Low volatility with a positive trend indicates stable, improving operations.
Insight Metrics
These metrics measure the quality and actionability of the insights you extract from voice feedback.
Theme Frequency
Track how often each theme appears in your feedback. The most frequently mentioned themes are your highest-priority focus areas. Watch for themes that are growing in frequency -- these represent emerging issues or opportunities.
Theme Sentiment
Not all themes are equal. A frequently mentioned theme with positive sentiment is a strength to maintain. A frequently mentioned theme with negative sentiment is a problem to fix. Track both dimensions together to prioritize effectively.
Urgency Distribution
Track the distribution of urgency scores across your feedback. An increasing proportion of high-urgency messages indicates escalating issues. Monitor this weekly as part of your crisis prevention strategy.
New Theme Emergence
Count the number of new themes identified by AI each month. A steady stream of new themes is normal as your program matures and people share more diverse feedback. A sudden burst of new negative themes warrants immediate investigation.
Action Metrics
These metrics measure whether your team is actually doing something with the feedback -- the ultimate determinant of program success.
Response Time
How quickly does your team acknowledge and act on urgent feedback? Set targets by urgency level: critical within 30 minutes, high within 4 hours, medium within 24 hours, low within one week.
Resolution Rate
What percentage of identified issues have been addressed with concrete action? Track this by theme to ensure that systemic problems are being resolved, not just individual incidents.
Feedback Loop Closure
How often do you communicate back to stakeholders about changes made based on feedback? The feedback loop is only closed when the people who gave feedback (or their peers) know that their voice led to change. Track communication frequency and content.
Impact Verification
After making a change based on feedback, did the underlying metric improve? For example, if you improved kitchen wait times based on feedback, did wait-time-related complaints decrease? This closes the measurement loop and validates that your actions are working.
Building Your Metrics Dashboard
Start with a simple weekly dashboard that includes these five core metrics:
- Total feedback volume (trend over 4 weeks)
- Average sentiment score (trend over 4 weeks)
- Top 3 themes by frequency
- Urgent alerts and resolution status
- Actions taken this week based on feedback
As your program matures, expand the dashboard to include channel comparisons, cohort analysis, and ROI tracking using our ROI measurement framework.
