Recording Requirements
To produce a high-quality clone, your recording should meet the following criteria:
- Record in a studio - use a quiet, professional recording environment. Avoid recording on phones to prevent unwanted noise or static.
- Sample rate - 48 kHz for best results.
- Speak naturally - be dynamic, avoid monotony. The clone will reflect the energy and character of your recording.
- Script - you can read any plain text of your choice. No specific script is required, just ensure the content is clear and varied.
Recording Duration
| Duration | What to expect |
|---|---|
| 1–2 minutes | A quick trial clone - gives a general idea of the cloned voice quality |
| 20–30 minutes | Recommended for best cloning performance and production-ready output |
Finding 20–30 minutes of clean studio recording can be challenging. A shorter recording of 1–2 minutes is enough to evaluate the results before committing to a full session.
Getting Started
Once your recording meets the criteria above, contact the SESTEK Sales Team. We take care of everything from there - processing, fine-tuning, and delivery. No technical setup required on your end.
