• Quality checks (clarity, pacing)
• Export formats (MP3, WAV)

Educational Delivery Characteristics

Target WPM: 130-150 words per minute Tone: Calm, authoritative, patient Energy: Measured and clear Pacing: Deliberate with pauses for comprehension

Voice Profile: Configured in parent skill's voice_profiles.json (narration profile)

• See PROFILE.md for style guidance
• Technical settings managed centrally

Core Workflow

1. Script Review

• Receive educational script or course content
• Identify key learning points
• Review technical terms and pronunciation
• Check for clarity and logical flow

2. Voice Generation

• Optimize script for instructional delivery
• Apply educational voice profile settings
• Generate voiceover with clear pacing
• Review for clarity and authority
• Re-generate unclear segments

3. Delivery

• Export in required format (MP3 for courses, WAV for video sync)
• Package with metadata (duration, WPM, key topics)
• Handoff to course packager or video editor

Quality Checklist

• Pronunciation of technical terms accurate
• Pacing allows for comprehension (130-150 WPM)
• Tone is calm and authoritative
• Key concepts emphasized appropriately
• Transitions between topics clear
• No rushed or confusing moments
• Audio quality high (no artifacts)
• Overall delivery feels patient and supportive

Script Optimization for Education

Best Practices:

• Break complex concepts into simple steps
• Use clear transitions between topics
• Emphasize key terms on first mention
• Include brief pauses after important points
• Spell out technical terms phonetically if needed
• Number steps explicitly ("First...", "Second...")

Example Optimized Script:

In this lesson, we'll learn three fundamental principles of 
time management.

First... the principle of prioritization. This means focusing on 
what truly matters, rather than what feels urgent.

Let's look at a practical example...

[pause]

The second principle is time blocking. Here's how it works...

Avoid:

• Rushing through complex concepts
• Assuming prior knowledge
• Skipping transitions
• Technical jargon without explanation
• Long, unbroken explanations

Using the Educational Generator

from src.Voiceover import VoiceoverGenerator

generator = VoiceoverGenerator(profile_type="narration")

result = generator.generate(
    script="In this lesson, we'll explore...",
    content_type="educational",
    optimize_script=True,
    output_filename="lesson-01.mp3"
)

print(f"Generated: {result['output_file']}")
print(f"Duration: {result['duration_seconds']}s")
print(f"WPM: {result['words_per_minute']}")

Educational Content Types

Course Lessons:

• Structured, logical flow
• Clear learning objectives
• Recaps and summaries
• WPM: 130-140

Tutorials:

• Step-by-step instructions
• Practical demonstrations
• Verification points
• WPM: 140-150

Explainer Videos:

• Concept introduction
• Visual synchronization points
• Clear conclusions
• WPM: 135-145

Training Materials:

• Professional, authoritative tone
• Compliance or certification focus
• Assessment preparation
• WPM: 130-140

Avoid

• Too Fast: Rushing → 130-150 WPM pacing
• Unclear Terms: Jargon → Plain explanations
• Monotone: Flat delivery → Calm but engaging authority
• No Structure: Rambling → Clear, logical progression

Escalate When

• Script has complex technical terms needing pronunciation guide
• Content requires visual synchronization timing
• Target audience level unclear (beginner vs advanced)
• Assessment or quiz content needs special treatment
• Timeline doesn't allow for quality review
