Technical Documentation Analysis & Feedback

Section titled “Technical Documentation Analysis & Feedback”

This documentation provides a solid foundation but needs significant improvements in structure, completeness, and user guidance. Here’s my detailed feedback:

  • Missing: Python version requirements
  • Missing: Expected audio format specifications (supported formats, file size limits, duration limits)
  • Missing: Clear explanation of LeMUR credit costs and consumption rates
  • Add: Minimum account tier requirements beyond “upgrade with credit card”
# Add this essential error handling section:
try:
transcript = transcriber.transcribe(audio_url)
if transcript.status == aai.TranscriptStatus.error:
print(f"Transcription failed: {transcript.error}")
return
except Exception as e:
print(f"Error during transcription: {e}")
return
  • Missing: How to validate audio files before processing
  • Missing: Handling of different audio formats and quality levels
  • Missing: Maximum file size and duration limits

The “Quickstart” and “Step-by-Step Instructions” contain nearly identical code. Recommendation:

  • Keep Quickstart as a complete, copy-paste example
  • Make Step-by-Step focus on explanations and variations
  • Add a “Complete Example” section at the end
## Suggested New Structure:
1. Overview & Use Cases
2. Prerequisites & Setup
3. Quick Start (complete example)
4. Detailed Walkthrough
5. Customization Options
6. Output Processing
7. Error Handling
8. Best Practices
9. Troubleshooting

Current: “Define the phases you want to identify” Improved:

### Defining Call Phases
Phases represent distinct stages in your phone call. Choose phases that match your specific use case:
**Customer Support Example:**
- Introduction: Greeting and problem identification
- Investigation: Gathering details and troubleshooting
- Resolution: Providing solutions or next steps
- Closure: Confirming satisfaction and ending call
**Sales Call Example:**
- Opening: Introductions and rapport building
- Discovery: Understanding customer needs
- Presentation: Showcasing products/services
- Close: Handling objections and finalizing
  • Add: Explanation of why VTT format is used
  • Add: Alternative input formats (plain text, SRT, etc.)
  • Add: Token consumption estimation
  • Add: Processing time expectations

Add these examples:

# Sales call phases
sales_phases = [
"Opening & Rapport",
"Needs Discovery",
"Product Presentation",
"Objection Handling",
"Closing"
]
# Medical consultation phases
medical_phases = [
"Patient Check-in",
"Symptom Discussion",
"Examination Planning",
"Treatment Recommendation",
"Follow-up Scheduling"
]

Add this critical section:

import json
# Parse and work with the results
response_data = json.loads(result.response)
# Extract specific phase information
for phase in response_data["phases"]:
duration = phase["end_time"] - phase["start_time"]
print(f"{phase['name']}: {duration:.1f} seconds")
print(f"Summary: {phase['summary']}\n")
# Find longest phase
longest_phase = max(response_data["phases"],
key=lambda x: x["end_time"] - x["start_time"])
print(f"Longest phase: {longest_phase['name']}")

Add:

# Validate API key
if not aai.settings.api_key or aai.settings.api_key == "YOUR_API_KEY":
raise ValueError("Please set your AssemblyAI API key")
# Show progress
print("Starting transcription...")
transcript = transcriber.transcribe(audio_url)
print(f"Transcription complete. Duration: {transcript.audio_duration}s")
print("Analyzing with LeMUR...")

Add troubleshooting section:

## Common Issues
### Transcription Fails
- Check audio file format (supported: mp3, wav, m4a, etc.)
- Verify file accessibility (URL or local path)
- Ensure file size under 5GB
### LeMUR Analysis Incomplete
- Try shorter audio files (under 30 minutes recommended)
- Simplify phase definitions
- Check account credits

Add:

## Best Practices
### Audio Optimization
- Use clear, high-quality recordings
- Minimize background noise
- Ensure speakers are distinguishable
### Phase Definition Tips
- Keep phase names simple and distinct
- Use 3-6 phases for optimal results
- Define phases that naturally occur in sequence
## Try It Now
Use our sample audio file to test the segmentation:
```python
# Use AssemblyAI's sample customer service call
sample_url = "https://storage.googleapis.com/aai-web-samples/customer-service-call.wav"
# Advanced LeMUR options
result = aai.Lemur().task(
input_text=transcript.export_subtitles_vtt(),
prompt=prompt,
final_model=aai.LemurModel.claude3_5_sonnet,
max_tokens=4000, # Control response length
temperature=0.1 # Lower temperature for more consistent results
)

Show how to integrate with common workflows (CSV export, database storage, visualization tools).

This documentation needs substantial expansion to become truly user-friendly and production-ready. Focus on the missing error handling, better examples, and clearer explanations as top priorities.
