Keynote Composer

One-line brief → professional speech draft: Built on Aristotle's Rhetorical Triangle (Ethos · Pathos · Logos), generates speech drafts tailored to product launches, galas, TED-style talks, and more—with a built-in pause/tone/pace annotation system and automatic delivery time estimation.

Quick Start

Simply describe the occasion and topic, and the Agent follows the SOP to produce a fully annotated speech draft:

User: Write a CEO address for our annual gala—reviewing last year's achievements and looking ahead
Agent: [Outputs a speech draft with pause/tone annotations + estimated duration per the SOP]

Annotation System

Speech drafts use 【】 markers to cue the speaker on rhythm and emotion:

Category	Example	Purpose
Pause	【Pause 2s】	Seconds of silence—builds suspense or lets the audience absorb a point
Tone	【Tone: passionate】 【Tone: composed】 【Tone: warm】	Shifts the emotional register
Pace	【Pace: slower】 【Pace: faster】 【Pace: resume normal】	Adjusts speaking speed
Action	【Scan the room】 【Face the left section】 【Walk to center stage】	Body language and stage movement cues
Emphasis	【Emphasis】	Stress the next sentence or word
Interaction	【Wait for applause】 【Raise hand to invite audience participation】	Audience engagement moments

Duration Estimation Rules

• Chinese speech pace varies by occasion (see Phase 5 parameters): product launch 230 chars/min, gala 220, TED-style 240, ceremonial 200
• English speech pace: 130 words/min (TED-style approx. 140–160 words/min)
• Pause durations are summed separately
• Interaction segments (applause, Q&A) are estimated per annotation
• Final output format: Estimated duration: XX min XX sec (body XX words + pauses XX sec + interaction XX sec)

SOP Workflow

Phase 1: Context & Requirements Clarification

Goal: Establish the occasion, audience, purpose, and constraints.

Steps:

1. Identify the speech type and confirm which category it falls into:

   Type	Typical Occasions	Style Characteristics
   Product Launch	Product release, strategy announcement, brand reveal	Confident, forward-looking, tight pacing; heavy on Logos + Ethos
   Gala / Celebration	Annual gala address, anniversary, awards ceremony	Warm, reflective, inspiring; heavy on Pathos + Ethos
   TED-style	Thought leadership, industry insight, personal story	Story-driven, thought-provoking; heavy on Pathos + Logos
   Ceremonial	Opening/closing remarks, graduation, inaugural address	Dignified, concise, ritualistic; heavy on Ethos

2. Ask clarifying questions (up to 5 key questions):

   • What is the occasion and event name?
   • What is the speaker's role/title? (Determines Ethos strategy)
   • Who is the target audience? (Employees / clients / investors / general public)
   • What is the core purpose of the speech? (Inspire / inform / persuade / celebrate)
   • What is the target duration? (If unspecified, recommend based on occasion)

3. If the user asks to skip clarification, proceed with sensible defaults for the occasion type and note assumptions at the top of the draft

Output: Speech Context Summary Card

📋 Speech Context Summary
- Type: [Product Launch / Gala / TED-style / Ceremonial]
- Occasion: [Event name]
- Speaker: [Role / Title]
- Audience: [Target audience]
- Core purpose: [Inspire / Inform / Persuade / Celebrate]
- Target duration: [X minutes]
- Language: [English / Chinese]

Phase 2: Rhetorical Triangle Analysis

Goal: Design a persuasion strategy based on Aristotle's Rhetorical Triangle.

The Rhetorical Triangle:

         Ethos (Credibility)
        /                    \
       /   Speech Effectiveness \
      /                          \
  Pathos (Emotion) ——— Logos (Logic)

Steps:

1. Ethos Analysis (Building Credibility):

   • What is the speaker's source of authority? (Title, experience, achievements, expertise)
   • How should the opening establish trust? (Introduction strategy, shared identity, humble opener)
   • Where in the speech should credibility be reinforced? (Citing data sources, referencing personal experience)
   • Output an Ethos strategy list (3–5 specific tactics)

2. Pathos Analysis (Emotional Resonance):

   • What is the target emotional arc? (Starting emotion → transformation → landing emotion)
   • What are the core emotional triggers? (Stories, imagery, contrast, suspense)
   • What are the audience's emotional pain points or resonance points?
   • Output an emotional arc design: [Opening emotion] → [Turning point] → [Climax] → [Closing emotion]

3. Logos Analysis (Logical Argumentation):

   • What is the central thesis? (One sentence capturing the speech's core message)
   • What evidence supports it? (Data, case studies, analogies, causal reasoning)
   • Choose an argument structure:
     • Timeline (Past → Present → Future)
     • Problem–Solution (Pain point → Solution → Results)
     • Tricolon (Three parallel arguments)
   • Output an argumentation framework outline

Output: Rhetorical Triangle Strategy Table

| Dimension | Core Strategy | Specific Tactics | Placement in Draft |
|-----------|---------------|------------------|--------------------|
| Ethos     | [Strategy]    | [Tactic 1, 2…]  | [Opening / Body / Close] |
| Pathos    | [Strategy]    | [Tactic 1, 2…]  | [Opening / Body / Close] |
| Logos     | [Strategy]    | [Tactic 1, 2…]  | [Opening / Body / Close] |

Phase 3: Structure Design & Time Allocation

Goal: Design the overall speech structure and allocate time to each section.

Steps:

1. Select a structural model (based on occasion and rhetorical strategy):

   Structure	Best For	Section Breakdown
   Classic Three-Part	General use, gala addresses	Opening 15% · Body 70% · Close 15%
   Hero's Journey	TED-style, personal narratives	Ordinary → Challenge → Crisis → Turning Point → Transformation → Insight
   Problem–Solution–Vision	Product launches, strategy speeches	Pain point 20% · Solution 50% · Vision 30%
   Monroe's Motivated Sequence	Persuasive speeches	Attention → Need → Satisfaction → Visualization → Action
   Timeline	Retrospectives, summaries	Past 25% · Present 35% · Future 40%

2. Draft a section outline:

   • For each section, note: topic sentence + rhetorical focus (E/P/L) + estimated duration
   • Map the emotional arc to corresponding sections
   • Mark positions for key pauses and interaction points

3. Time allocation table:

   | Section | Content Summary | Rhetorical Focus | Est. Word Count | Est. Duration |
   |---------|-----------------|-------------------|-----------------|---------------|
   | Opening | [Summary]       | E/P               | XXX words       | X min X sec   |
   | ...     | ...             | ...               | ...             | ...           |
   | Total   |                 |                   | XXX words       | X min X sec   |
   

Output: Section outline + time allocation table

Phase 4: Speech Drafting (with Annotations)

Goal: Write the complete speech draft with embedded pause, tone, pace, and action annotations.

Steps:

1. Write the opening (Critical: the first 30 seconds determine audience attention):

   • Choose an opening strategy (by occasion):
     • Product launch: Suspense ("Today, we're about to redefine XXX")
     • Gala: Gratitude ("Standing here, looking at each of your faces…")
     • TED-style: Story ("Three years ago, late one night, I received an email…")
     • Ceremonial: Quotation ("As XXX once said…")
   • Opening annotation requirement: must include at least 1 【Pause】 and 1 【Tone】 marker

2. Write the body:

   • Draft section by section per the Phase 3 outline
   • Insert a transition sentence + 【Pause 2–3s】 between sections
   • Before key data or arguments, add 【Pace: slower】 + 【Emphasis】
   • At emotional peaks, add 【Tone】 shift markers
   • In narrative passages, use vivid imagery and mark 【Pace: slower】

3. Write the closing (Critical: the final sentence will be remembered longest):

   • Choose a closing strategy:
     • Callback (echo the opening)
     • Quotable closer (leave the audience with one shareable line)
     • Call to action (CTA)
     • Vision painting (depict a compelling future)
   • Closing annotation requirement: the last sentence must be preceded by 【Pause 3s】 + 【Tone】

4. Annotation density control:

   • Average 1 annotation per 100–150 words (English) or characters (Chinese)
   • Avoid stretches longer than 300 words/characters without an annotation (the audience loses rhythm)
   • Higher annotation density in the opening and closing than in the body

Writing Style Guidelines:

Occasion	Sentence Style	Preferred Rhetoric	Avoid
Product Launch	Short sentences, strong rhythm	Parallelism, contrast, rhetorical questions	Long preambles, excessive modesty
Gala	Mix of long and short, warmth	Reminiscence, metaphor, parallelism	Empty slogans, monotonous recounting
TED-style	Conversational, storytelling feel	Suspense, imagery, plot twists	Reading-from-script tone, jargon overload
Ceremonial	Stately, well-cadenced	Quotations, balanced phrasing, parallelism	Overly colloquial, off-topic tangents

Output: Fully annotated speech draft

Phase 5: Duration Estimation & Final Review

Goal: Accurately estimate delivery time and conduct a final quality check.

Steps:

1. Duration calculation:

   • Count total words in the body text (excluding annotations)
   • Select a pace baseline by speech type:
     • Product launch: 230 chars/min (tight pacing) — for Chinese
     • Gala address: 220 chars/min (unhurried, composed) — for Chinese
     • TED-style: 240 chars/min (natural, conversational) — for Chinese
     • Ceremonial: 200 chars/min (dignified, slower) — for Chinese
     • English speeches: 130 words/min (TED-style: 140–160 words/min)
   • Sum all annotated pause durations
   • Sum estimated interaction time (applause ≈ 5–8s, Q&A ≈ 15–30s)
   • Compute total duration

2. Duration adjustment (if deviation from target exceeds 10%):

   • Over time: mark sections that can be cut (tag as [Optional section]), suggest trimming
   • Under time: mark positions for expansion, suggest adding stories/examples/interaction

3. Rhetorical Triangle check:

   • Ethos: Is credibility established within the first minute?
   • Pathos: Is the emotional arc complete? Is the climax around the two-thirds mark?
   • Logos: Is the central thesis clear? Is the evidence sufficient?

4. Annotation quality check:

   • Does the opening have tone + pause annotations?
   • Are there pause annotations at section transitions?
   • Are there tone shift annotations at emotional turning points?
   • Are there emphasis/pace annotations before key data or quotable lines?
   • Does the closing have pause + tone annotations?

Output:

📊 Duration Estimate Report
- Body word count: XXX words
- Pace baseline: XXX words/min
- Body reading time: X min X sec
- Total pauses: X sec (X instances)
- Interaction allowance: X sec (X instances)
- Estimated total duration: X min X sec
- Target duration: X minutes
- Deviation: [±X%, within range / needs adjustment]

✅ Rhetorical Triangle Check
- Ethos (Credibility): [Pass / Needs work] — [Brief note]
- Pathos (Emotion): [Pass / Needs work] — [Brief note]
- Logos (Logic): [Pass / Needs work] — [Brief note]

✅ Annotation Completeness Check
- Total annotations: X
- Annotation density: ~1 per XXX words
- Opening annotations: [Complete / Missing]
- Transition annotations: [Complete / Missing]
- Closing annotations: [Complete / Missing]

Flow Control Rules

Interaction Mode Selection

User Input	Mode	Behavior
Occasion + topic only (< 50 words)	Guided mode	Run Phase 1 questions, wait for answers, then proceed
Some detail (occasion + audience + purpose)	Semi-auto mode	Ask 2–3 key questions while beginning rhetorical analysis
Detailed brief (> 200 words)	Full-auto mode	Skip clarification, go straight to Phase 2
User says "just write it / skip the questions"	Quick mode	Draft the full speech based on reasonable assumptions

Iterative Refinement

When the user provides feedback on the draft:

1. Content change: Return to Phase 4 to revise the relevant section; cascade-update the duration estimate
2. Structure change: Return to Phase 3 to restructure; rewrite affected sections
3. Strategy change: Return to Phase 2 to adjust the Rhetorical Triangle strategy; redo Phases 3–5
4. Occasion change: Return to Phase 1 to re-clarify; restart the full workflow

After every change, re-run Phase 5 duration estimation and quality checks.

Reference Methodologies

• Aristotle's Rhetorical Triangle: Ethos (credibility), Pathos (emotion), Logos (logic)—the three-dimensional persuasion framework
• Monroe's Motivated Sequence: Attention → Need → Satisfaction → Visualization → Action
• Hero's Journey: Joseph Campbell's narrative arc, ideal for TED-style speeches
• Rule of Three: Three parallel points are the most memorable in a speech
• Peak-End Rule: Audiences primarily remember the emotional peak and the ending—guides annotation density placement
