Voice Clone & Podcast — Audio AI for Personal Brand (Global)
This skill focuses on audio AI — voice clone, podcast, audiobook, voiceover.
Pairs with 24-ai-avatar-production-global (video) — combine both for full content stack coverage.
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?

5 common mistakes
- AI voice sounds robotic: sample too short or monotonic. Fix: re-record 3-5 minutes with varied emotions (happy, serious, sad).
- Mispronounced names/jargon: TTS engines mishandle proper nouns. Fix: use phonetic spelling (e.g., "Anthropic" -> "an-THROW-pic") in the script.
- Audio clipping: levels too hot. Fix: target -3dB peak, -16 LUFS loudness.
- Background noise/echo: untreated room. Fix: small room with curtains and rugs, or apply NVIDIA Broadcast / Krisp / Adobe Enhance Speech.
- Boring podcast: no editing, too many "ums". Fix: Descript auto-removes filler words, add light background music (-25dB).
2. Information collection
Ask up to 4 questions before starting:
- Main use case? Short voiceover (TikTok/Reels) / Podcast 30-60 min / Audiobook?

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
[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.

8. Audio QA + Disclosure
5 QA criteria
- Clarity (10 pts): voice clear, no rasp, no stuttering. Test: play on phone speaker, still intelligible.
- No clipping (10 pts): peak below -1 dB. Tools: Audacity, Adobe Audition, Reaper.
- No background noise (10 pts): no fans, traffic, neighbors. Tools: Krisp, NVIDIA Broadcast, Adobe Enhance Speech.
- Consistent loudness (10 pts): stable -16 LUFS (podcast) or -14 LUFS (TikTok). Tool: loudness meter in DAW.
- Natural pauses (10 pts): human-like pacing. Manual review: listen 3 times.
Pass: 40+/50. Below 40 = re-render or re-record.

223## 6. 1-on-1 podcast with an AI co-host
224
225> **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.
226
227### Setup — prompt-engineering the AI personality
228
229**Step 1: Define the AI co-host's personality**
230```
231Name: [AI co-host name]
232Personality: curious, asks deep follow-ups, occasionally light humor
233Role: asks the host questions, doesn't talk too much
234Speaking style: casual, natural, addresses the host by first name
235Knowledge level: average — asks questions like a listener would
236Catchphrases: "Wow, that's wild." / "What does that mean exactly?" / "Can you go deeper?"
237```
238
239**Step 2: Create a separate voice clone for the AI co-host**
240- Use a different voice than the host (e.g., woman vs man, or different accent)
241- Clone from a consenting friend, or use one of ElevenLabs' built-in voices
242
243**Step 3: Tool stack**
244- **ElevenLabs:** generate the AI co-host voice
245- **Riverside:** record the host live
246- **Descript:** edit + splice in the AI co-host (text-to-audio)
247
248### Q&A script template
249
250```
251[INTRO]
252Host: Hey everyone, today [AI co-host] and I are diving into...
253AI co-host: Hi all, I'm [name]. Today I want to dig into [topic] from [host]'s
254 point of view. Let's go!
255
256[BODY — 5-7 Q&A pairs]
257AI co-host: [Broad opening question]
258Host: [Answers 2-3 minutes]
259AI co-host: [Deeper follow-up]
260Host: [Answers with a concrete example]
261... repeat 5-7 times ...
262
263[OUTRO]
264AI co-host: Thanks [host] for sharing. The biggest thing I learned was...
265Host: Thanks [AI co-host]. If you have questions, drop them in the comments...
266```
267
268**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.
