1. Newbie Guide

What is audio AI and how is it different from video AI?

Audio AI is the tech behind synthetic voices that sound nearly human — from a sample of your voice, AI learns and produces a synthetic clone (voice clone). You write text -> AI reads it back (Text-to-Speech).

Differences vs video AI:

• Video AI (skill 24): produces video with face + voice -> talking head, social video
• Audio AI (this skill): produces voice only -> podcast, audiobook, voiceover, narration

When to use audio AI instead of video?

Situation	Pick audio AI	Pick video AI
Long-form content (>10 min)	YES — podcast format	NO — too long for video
Don't want to be on camera	YES	NO
Need volume content fast	YES — 1 podcast = 10 shorts	YES but more expensive
Audience listens while driving / at gym	YES	NO
Need visuals to demo	NO	YES
Personal brand thought leader	YES — podcast = authority	YES — if face brand exists

Time and cost

Task	Time	Cost (USD/mo)
Voice clone setup	30-60 min	$5-22 (ElevenLabs Starter/Pro)
60s voiceover (TikTok)	5-10 min	$5-22
30 min solo podcast	1-2 hrs	$22-99 (ElevenLabs + Riverside)
Audiobook chapter (15 min)	30-45 min	$22-99
1 podcast -> 10 clips	1-2 hrs	$0-30 (Descript/Opus Clip)

5 common mistakes

1. AI voice sounds robotic: sample too short or monotonic. Fix: re-record 3-5 minutes with varied emotions (happy, serious, sad).
2. Mispronounced names/jargon: TTS engines mishandle proper nouns. Fix: use phonetic spelling (e.g., "Anthropic" -> "an-THROW-pic") in the script.
3. Audio clipping: levels too hot. Fix: target -3dB peak, -16 LUFS loudness.
4. Background noise/echo: untreated room. Fix: small room with curtains and rugs, or apply NVIDIA Broadcast / Krisp / Adobe Enhance Speech.
5. Boring podcast: no editing, too many "ums". Fix: Descript auto-removes filler words, add light background music (-25dB).

4. Three use cases

Use case A: Short voiceover for TikTok/Reels (Energetic)

Spec:

• Length: 15-60s
• Pace: fast (180-220 wpm) — younger English-speaking audience
• Tone: energetic, slightly higher pitch, exciting
• Audio levels: -14 LUFS (TikTok), peak -1 dB
• CTA: clear in the last 5 seconds

Script template (30s):

[HOOK 0-3s] "Did you know [shocking stat]?"
[PROBLEM 3-10s] "Most people are still stuck in [wrong loop]"
[SOLUTION 10-22s] "I tried [method], and here are 3 things..."
[PAYOFF 22-27s] "Result: [specific number]"
[CTA 27-30s] "Comment 'YES' to get the full breakdown"

Voice settings (ElevenLabs):

• Stability: 35-45 (low — allows variation)
• Similarity: 75-85
• Style: 50-65 (boost expressiveness)
• Speaker Boost: ON

Use case B: Podcast 30-60 min (Conversational)

Structure:

• Intro (1-2 min): hook + introduce topic + welcome listeners
• Body (25-50 min): 3-5 main segments, each 5-10 min
• Ad slot (optional): 3-5 min after intro, or mid-body
• Outro (1-2 min): recap + CTA + thanks

Pacing:

• Conversational pace: 140-160 wpm
• 1-2s pause after important sentences
• Segment transitions: 2-3s pause + audio sting

Sound design:

• Background music: -25 to -30 dB (very subtle)
• Stings/transitions: -15 dB, 1-2s
• Voice levels: -16 LUFS (podcast standard), peak -1 dB

Voice settings (ElevenLabs):

• Stability: 60-75 (high — consistent across 30+ minutes)
• Similarity: 85-95
• Style: 30-40 (natural, not over-expressive)
• Speaker Boost: ON

Use case C: Audiobook (Mid-tempo)

Structure:

• Chapter intro: "Chapter [X]: [Title]" — 2s pause
• Chapter body: 10-20 min/chapter, 1s pause between paragraphs
• Chapter end: 3s pause before next chapter

Pacing:

• Mid-tempo: 150-170 wpm
• Natural breath every 2-3 sentences
• Dialogue: subtle voice shifts per character (fiction)

Consistency check (most important):

• Render Chapter 1 and Chapter 5 -> compare voice -> must match 95%+
• If voices drift: re-clone with a longer sample (5+ min)
• Pronunciation guide: build a database of proper nouns + custom phonetics

Voice settings (ElevenLabs):

• Stability: 70-85 (very high — consistent for hours)
• Similarity: 90-95
• Style: 20-30 (calm, even)

6. 1-on-1 podcast with an AI co-host

Use case: solo podcaster who wants conversational format but can't find a co-host. AI co-host = a second AI voice that asks questions while you answer.

Setup — prompt-engineering the AI personality

Step 1: Define the AI co-host's personality

Name: [AI co-host name]
Personality: curious, asks deep follow-ups, occasionally light humor
Role: asks the host questions, doesn't talk too much
Speaking style: casual, natural, addresses the host by first name
Knowledge level: average — asks questions like a listener would
Catchphrases: "Wow, that's wild." / "What does that mean exactly?" / "Can you go deeper?"

Step 2: Create a separate voice clone for the AI co-host

• Use a different voice than the host (e.g., woman vs man, or different accent)
• Clone from a consenting friend, or use one of ElevenLabs' built-in voices

Step 3: Tool stack

• ElevenLabs: generate the AI co-host voice
• Riverside: record the host live
• Descript: edit + splice in the AI co-host (text-to-audio)

Q&A script template

[INTRO]
Host: Hey everyone, today [AI co-host] and I are diving into...
AI co-host: Hi all, I'm [name]. Today I want to dig into [topic] from [host]'s
            point of view. Let's go!

[BODY — 5-7 Q&A pairs]
AI co-host: [Broad opening question]
Host: [Answers 2-3 minutes]
AI co-host: [Deeper follow-up]
Host: [Answers with a concrete example]
... repeat 5-7 times ...

[OUTRO]
AI co-host: Thanks [host] for sharing. The biggest thing I learned was...
Host: Thanks [AI co-host]. If you have questions, drop them in the comments...

Tip: pre-write 7-10 AI co-host questions in a doc, record host responses in one go. Then generate AI co-host audio in ElevenLabs and splice in via Descript.

7. Repurpose pipeline 1:10 (1 podcast -> 10 short clips)

Workflow overview

[1] Record 60-min podcast (Riverside)
        v
[2] Auto-transcript (Descript / Riverside)
        v
[3] Identify hooks (10-15 quotable lines)
        v
[4] Cut 30-60s clips per quote (Opus Clip / Descript)
        v
[5] Add captions (auto-caption)
        v
[6] Distribute across 4 platforms

How to identify hooks

Find moments in the transcript with these traits:

• Bold statement: "I think 90% of founders are doing this wrong"
• Counter-intuitive: "Raising prices actually grew revenue"
• Specific number: "Went from $0 to $1M in 6 months"
• Personal story: "On my first startup I lost $200K"
• Actionable tip: "3 specific steps you can take today"

Target: 10-15 hooks per 60-min podcast. Pick the 10 best.

Tool stack

• Descript: auto-clip — select sentences, export short clips (free tier 1 hr/month)
• Opus Clip: AI auto-finds viral moments + auto-format vertical/horizontal ($19-99)
• Riverside Magic Clips: built-in to Riverside Pro ($29)
• CapCut + ChatGPT: manual but free — paste transcript, ChatGPT extracts hook candidates

Distribution across 4 platforms

Platform	Format	Length	Caption	Bonus
TikTok	9:16 (1080×1920)	30-60s	Bold caption on top	Trend audio overlay (low volume)
Instagram Reels	9:16	15-90s	Clean subtitle, sans-serif font	Strong cover image
YouTube Shorts	9:16	<60s	Auto-caption	Title with target keyword
LinkedIn audio	1:1 (square video w/ audio)	60-120s	Subtitle below	Long-form thread (carousel)

Pro tip: each clip should target one platform with platform-specific captions and cover image. Maximizes reach.
