How AI voice-over works in HookWise

Script in, audio clip out

You write the script, pick one of the 8 voices and add a short style instruction, such as "speak in English with an enthusiastic tone". HookWise sends the text to Gemini TTS with your API key, and Gemini returns the audio. The clip lands on the audio track of the editor, ready to trim and move.

The style instruction sets both the language and the delivery, so you can ask for a calm, slow read or a quick, upbeat one. HookWise can also make captions from the script on the timeline. Results are saved in the library, so the same text with the same voice is not generated, or billed, twice.

Where a generated voice fits

AI voice-over fits videos where nobody talks on camera: product demos, B-roll montages, slide recaps, channel intros and tutorials made from screen recordings. It also helps when you want to hear one script in several voices and pick the one that suits your brand.

Keep scripts short and written for the ear. Use one idea per sentence, write numbers the way they should be read, and spell brand names the way you want them pronounced. Generate, listen, then adjust the wording before you switch voices. Music ducking lowers your background music under the narration, and volume keyframes let you shape the mix by hand.

What it needs and costs

Voice-over needs the Pro or Studio plan, your own Gemini API key and an internet connection. Google bills the TTS usage to that key at Google's rates. Which languages and accents sound natural depends on Gemini TTS, so test your own script during the 7-day trial.

The 8 voices are Kore, Puck, Charon, Aoede, Fenrir, Leda, Orus and Zephyr. HookWise does not clone voices. To use your own voice, record it, import the file and clean it with Enhance Speech. Check each platform's rules on labeling AI-generated audio before you post.
