Use Cases

Quality Assurance

Automatically evaluate every call for compliance with company standards. Identify agents needing coaching.

Compliance Monitoring

Ensure regulated industries (healthcare, finance) meet compliance requirements. Generate audit reports.

Training & Coaching

Identify common mistakes and improvement areas. Create targeted training programs.

Customer Insights

Extract recurring issues, sentiment trends, and customer pain points from call data.

Performance Metrics

Track agent performance over time. Set benchmarks and measure improvement.

Risk Management

Flag problematic calls for review. Identify potential legal or PR risks early.

Best Practices

Writing Effective Analysis Fields

Be Specific

❌ “Rate the call quality” ✅ “Did the agent actively listen and acknowledge the customer’s concerns?”

Use Clear Scales

❌ “Rate professionalism 1-10” (undefined) ✅ “Rate professionalism: 1=Rude, 5=Neutral, 10=Exceptionally polite”

Keep It Focused

Limit to 5-10 key metrics. Too many fields increase analysis time and cost.

Include Action Items

Always have a text field for “Improvement areas” or “Action items” to get actionable feedback.

Analysis Frequency

Use Case	Recommended Frequency
Quality Assurance	100% of calls
Compliance	100% of calls
Training	10-20% random sample
Customer Insights	100% of calls
Performance Reviews	All calls + monthly summary

Cost Optimization

Tips:

Use GPT-5 Nano for high-volume simple analysis
Analyze only completed calls (skip abandoned/failed)
Limit text fields to 200 words max
Batch analysis during off-peak hours (coming soon)

Troubleshooting

Analysis is taking too long

Problem: Analysis typically takes 10-30 seconds per call. If longer:Solutions:

Reduce number of fields
Use faster model (Nano or Flash Lite)
Shorten text field descriptions
Check if transcript is very long (>30 min call)

Analysis results are generic or unhelpful

Problem: Field descriptions are too vague.Solution: Be more specific:

❌ “Rate the agent”
✅ “Rate how well the agent explained the solution in simple terms”

Some fields are empty in results

Problem: Optional fields may be skipped if AI can’t determine answer.Solution:

Make critical fields required (optional: false)
Improve field descriptions
Add examples to descriptions

Analysis cost is too high

Solutions:

Switch to cheaper model (Nano or Flash Lite)
Analyze sample instead of 100% of calls
Reduce number of text fields (most expensive)
Shorten analysis prompts
