Video: Voiceover, Subtitles and Sound

Sound is half the impression a video makes. In Telematic, voiceover, subtitles and music are configured once in a preset and then work automatically. ## Voices The library offers realistic neural voices for different languages. The voice is chosen in the video preset; there you can also set the **voice character** — a free-form description of the delivery ("calm narrator", "energetic host") that shapes the performance — and the **speech rate**. Before voicing, the text goes through automatic preparation: numbers and abbreviations are expanded into words ("$1,500" becomes "one thousand five hundred dollars") so the synthesis doesn't stumble. The voiceover language is pinned to the project's content language — the voice won't "flip" to another language because of foreign words in the text. ## Your own voiceover You can voice any scene yourself: - record or prepare the audio and **upload the file to the scene** — it's free, and no synthesis is run for that scene; - or open the built-in **audio editor**: waveform view, microphone recording, basic processing and undo — all in the browser, no extra software. Subtitles keep working either way: the system transcribes your recording itself and aligns the text to the timing. ## Subtitles Subtitles are generated automatically and synced to the audio word by word. You can configure the style and the **position in the frame**: simply drag and resize the subtitle box in the preview — for example, lift it above the Shorts interface overlay. The position is saved in the preset. ## Music and volume levels The preset defines background music and **separate volume levels**: voice and music are adjusted independently. For YouTube, **automatic loudness normalization** to the platform standard (−14 LUFS) is applied — your videos sound consistently loud and don't "sink" next to others. ## Cost Voiceover is billed by duration: **1 token per 6 seconds** of finished speech. Uploading your own voiceover is free. The full cost breakdown of a video is in ["Tokens and Billing"](/en/help/tokens-and-billing).
