AI Voiceovers for Livestream Selling and Product Videos

A sales pitch lives on energy. Pace, emotion and rhythm all sit a notch above normal speech, and generic TTS reads it like a manual. Here is the full recipe — the first clip in the homepage gallery is the result.

1. Pick a high-energy character

  • Livestream Host — fast, excited, persuasive; built for "three, two, one, link's up".
  • E-sports Caster — escalating hype, perfect for countdowns and flash sales.
  • Shonen Hero — sports, gadgets, gaming.
  • Playful Sweetheart — beauty, snacks, pets.

All are character voices with portraits and previews in the voice gallery.

2. Control the rhythm with tags

The flagship model understands emotion tags. The three a pitch needs most:

[excited] Friends, I've used this tumbler for three months!
[laughs] The brand manager just turned green —
[excited] Only three hundred left. Three, two, one — link's up!

One tag per line, at the start; leave a short line before the countdown to build tension. More in the emotion-tag cheatsheet.

3. Two hosts sound more like a real stream

Real streams are rarely one voice. Use multi-speaker dialogue for host + sidekick banter in a single take — the "two-host livestream" demo on the homepage is Livestream Host × Playful Sweetheart.

4. Batch: one script, many versions

Swap voice, pace and opening line to get five A/B variants from one script; for overseas stores switch the language and the same character speaks English, Spanish or Japanese. Voiceover is billed per character — a 200-character pitch is about 14 credits on the standard model, so the Starter plan (600 credits) covers 40+ clips.

Hear a live-stream close

The live-selling cadence is the hardest read to describe in words — listening beats explaining:

5. Subtitles and delivery
