Turn the current script into playable speech.
Synthesis creates vocal audio for the selected text and voice. Preview helps you judge the creative; Download renders the chosen creative and dynamic values into a deliverable file.
Know the vocal state
| State | What you hear | Required action |
|---|---|---|
| Not synthesized | No generated performance for the current paragraph. | Select a voice and synthesize. |
| Fresh | Audio matches the current text and relevant settings. | Preview or continue production. |
| Stale | The earlier take may still play, but it no longer represents the current model. | Synthesize again before approval or export. |
Synthesize a creative
- Finish the text and choose the intended voice.
- Check dynamic values in the current preview.
- Start the vocal synchronization or synthesis action.
- Review the credit confirmation.
- Wait for audio URL, duration, waveform, and fresh status.
- Play the generated paragraph in context.
What makes speech stale
- Changing the spoken text.
- Replacing the voice.
- Applying an AI rewrite or enhancement that changes the vocal representation.
- Changing a dynamic option that needs its own generated outcome.
Moving an existing clip changes timing, not its words. Resizing generated speech can change effective speed; listen again even when the audio remains available.
Preview before rendering
Use ordinary playback for fast editorial checks. In Mix, choose between raw, client-side Quick, and rendered HQ preview depending on what you need to verify. The Mixing guide explains those differences.
- Start playback before the changed clip, not exactly on it.
- Listen through the following transition.
- Check the default and every business-critical dynamic option.
- Use HQ before approving server-side ducking or mastering.
Download the current result
- Open Download.
- Review the selected creative and available variant values.
- Choose the required MP3 or WAV/PCM format.
- Generate the variant.
- Save the file and verify its name, duration, and playback.
The final generation applies the project's production chain. A downloaded file can therefore differ from a lightweight browser preview.
Download All and variant count
A dynamic project can produce combinations across creatives and criteria. Before using Download All:
- count enabled creatives;
- review every dynamic criterion and its options;
- remove test or unused alternatives;
- confirm naming and expected output count;
- allow time and storage for the complete render set.
Final verification
- Content — the file contains the intended creative and dynamic values.
- Duration — it fits the booked inventory.
- Format — codec, sample rate, bit depth, and bitrate meet the destination specification.
- Mix — speech remains intelligible throughout.
- Master — loudness and peak targets match the delivery requirement.
- Identity — the filename can be mapped back to project, creative, and variant.
