Aytada generates professional voiceover as part of the video ad pipeline. The voiceover is synthesized from your ad script, delivered by an automatically selected voice matched to your persuasion trigger, and merged with your video clips during the final stitching step. You can also clone a spokesperson voice from a short audio sample and use it as a drop-in replacement on any project. Cost: 5 credits per voiceover.Documentation Index

Voice synthesis
Aytada uses a high-fidelity text-to-speech system as its primary voiceover model. It produces natural, expressive narration suitable for direct-response ads, brand films, and UGC-style content. Emotion tags embedded in the script (for example,[excited] at the hook or [urgently] at the CTA) allow different sections of the script to carry different emotional registers without changing the voice.
If the primary synthesis service is unavailable or times out, a fast fallback model activates automatically. You receive the same credit deduction and a finished voiceover either way — the switch is transparent.
Voice selection
Aytada automatically selects the best-matched voice for your persuasion trigger. You can also choose manually from eight available voices in the Studio.| Voice | Character | Persuasion trigger match |
|---|---|---|
| Adam | Professional male | Authority |
| Jessica | Expressive American female | Liking, Reciprocity |
| Chris | Casual male | Social Proof, Consistency |
| Charlotte | Energetic female | Scarcity & FOMO |
| George | Warm British male | Luxury / Cinematic |
| Sarah | Warm female | Emotional |
| Daniel | Deep male | Direct Response |
| Laura | Upbeat female | Trend / UGC |
Voice auto-selection uses your persuasion trigger as the primary signal. If you manually override the voice in the Studio, your selection is preserved for all future regenerations on that project.
Tone-aware delivery settings
Each ad tone maps to a set of voice delivery parameters that control naturalness, expressiveness, and consistency. These settings are applied automatically when you generate voiceover.| Ad tone | Stability | Similarity | Style | Effect |
|---|---|---|---|---|
| Funny | 0.35 | 0.75 | 0.70 | High expressiveness, comedic timing, natural variation |
| Luxury | 0.80 | 0.85 | 0.15 | Controlled, measured, minimal stylization |
| Aggressive | 0.40 | 0.80 | 0.65 | High energy, punchy delivery |
| Minimal | 0.70 | 0.80 | 0.20 | Clean and restrained |
| Professional | 0.60 | 0.80 | 0.30 | Balanced clarity and warmth |
How voiceover is merged with video
After the voiceover is generated, it is stored as an audio asset attached to your project. During the Stitch step, the cloud render service sequences all video clips on one track and overlays the voiceover on a separate track. The video’s own audio (ambient sound, music generated natively by the video model) is automatically ducked to 30% volume so the voiceover remains clear and intelligible throughout. If you generated a background music track or jingle separately, it can be mixed in at this same step as an additional audio layer.Voice cloning
If you have a specific spokesperson — yourself, a brand character, or a talent you have rights to — you can clone their voice from a short audio sample and use it for all voiceovers on your account.Record or prepare a sample
Record a clean audio sample of the voice you want to clone. The sample should be 5–30 seconds long, contain only one speaker, and be free of background music, echo, or noise. MP3 and WAV formats are both accepted.
Upload in the Studio
Open your project in the Studio and navigate to the Voiceover module. Select Clone a Voice, then upload the audio file.
Regenerating voiceover
You can regenerate the voiceover on any existing project from the Studio without re-rendering the video clips. This is useful when:- You want to try a different voice or persuasion trigger
- The script was edited after the initial voiceover was generated
- You want to apply a cloned voice to a project that previously used a library voice
