How AI Voiceover Credits Work: Per-Character Pricing by Model

The complete VoiceSmiths credit rules: text-to-speech billed per character (7 credits per 100 on standard models, 4 on fast models), dialogue and long-form at the same rate, per-job prices for transcription, voice changer, sound effects and dubbing, automatic refunds, and how many characters each plan buys.

Most AI voice tools bill from a black box. Ours is written down here, and the generate button shows the exact estimate before you click.

1. Text to speech: characters × model

| Model | Per 100 chars | 200-char clip | 1,500-char episode | | --- | --- | --- | --- | | Resona Flash / Turbo (fast, low latency) | 4 credits | 8 | 60 | | Resona Multi (standard, 70+ languages) | 7 credits | 14 | 105 | | Resona Ultra (flagship, emotion tags) | 7 credits | 14 | 105 |

Anything under 100 characters counts as 100.
Multi-speaker dialogue uses the flagship rate on the combined script.
Long-form audiobooks are billed on total length — a 50,000-character job is about 3,500 credits on the standard model.

Fast models cost half upstream, so they cost half here. When to use them: picking the right TTS model.

2. Everything else: per job

| Capability | Credits | | --- | --- | | Speech to text (90+ languages, word timestamps) | 20 | | Voice changer (performance kept, timbre swapped) | 15 | | Vocal isolation | 10 | | Forced alignment (recording + script → timeline) | 5 | | Sound effect | 10 | | Music | 40 | | Voice design / voice clone | 20 / 30 | | Video dubbing (up to ~3 minutes) | 700 | | Voice-agent call (studio, 60 s) | 15 |

3. Failures are free

Any failed generation is refunded in full, automatically.

4. What each plan buys

| Plan | Credits / month | Standard-model characters | Fast-model characters | | --- | --- | --- | --- | | Starter $5 | 600 | ≈ 8,500 | ≈ 15,000 | | Creator $19 | 2,400 | ≈ 34,000 | ≈ 60,000 | | Pro $89 | 10,000 | ≈ 140,000 | ≈ 250,000 |

Yearly plans are cheaper and credit packs never expire — see pricing. Alipay, WeChat Pay and card (Stripe) are all accepted.
