“The simplicity of turning recordings you already have into great content is priceless. It turns content from noise into a value-add for any business or personal brand.”
Voice profile
Trained on how you talk,not how you prompt.
SparkVox's voice profile learns from your recordings, every approval and edit in the draft review, and your top-performing LinkedIn posts. It compounds across projects - you never re-explain who you are each session.
Free to sign up. Card required for full access.
No charge until day 15.
The short answer
A voice profile that actually sounds like you needs source material from how you communicate naturally - sales calls, podcasts, interviews - not generic prompts or scraped LinkedIn posts. SparkVox builds that profile from transcripts and compounds it with every edit and top-performing publish. Voice Confidence (0-100) tracks how much Sparky has learned.
What the profile learns from
Four signals feed every draft. None of them require you to write a style guide.
Brief Sparky
Who you help, topics you own, and constraints you set once in Settings. Brief Sparky shapes angle and audience on every generation alongside your voice profile.
Transcript depth
Tone, sentence rhythm, vocabulary, and how you build to a point - learned from every recording you process, not from a style guide you wrote to sound professional.
Post approvals andedits
Every change you make before approving teaches Sparky what to avoid and what to keep. Edits compound into the profile the same way approvals do.
Post Analytics
Your top-performing direct LinkedIn publishes feed back into future drafts. What actually resonated on the feed shapes the next project.
Why transcripts beat style guides
Most AI tools learn from what you type about yourself. SparkVox learns from what you actually said.
| Input method | What it captures | SparkVox |
|---|---|---|
| ChatGPT / Claude session | Nothing after you close the tab | Voice profile deepens across every project |
| Scraped LinkedIn posts | Your curated, performative writing self | How you talk on calls, podcasts, and interviews |
| Jasper Brand Voice | Written samples and style guides you upload | Recordings of you explaining your expertise out loud |
| Prompt: write like me | Surface patterns for one session only | Persistent profile with Voice Confidence (0-100) |
Voice Confidence
A score that tracks depth, not vanity.
Voice Confidence (0-100) in Settings shows how much transcript material Sparky has learned from. It climbs with every project you process and every edit you make before approving.
- Upload 1: baseline tone and vocabulary from first transcript
- Uploads 3-5: hooks and rhythm start matching your speech
- Uploads 5-6: most users see drafts need noticeably less editing
- Ongoing: Post Analytics reinforces what performed on LinkedIn
- Edits: every correction before approve sharpens future drafts
"I had to admit, prior to this: do I want AI to create my LinkedIn posts? But it's not, because it's also my interview - my human-to-human conversation that it's based upon. So it's not bullshit. Some people just go to their AI, create a post, and don't even know themselves what they're writing about. I'm not a big fan of that."
