What it does

The voice picker can show voices from connected ElevenLabs, Sarvam and Deepgram providers. Voice availability depends on account access, provider configuration and language; the picker separates the voice from its language and model.

How to use it

Connect a voice provider, open the project's Voice step, filter and preview available voices, then generate and listen to the narration. You can also choose My own recording or No voice (captions + music).

Where it helps

A voice that fits the audience and language can make a walkthrough easier to follow. Listen to the full narration, check pronunciation and regenerate after edits.

A practical example

A product owner can listen to a short line in two available voices, compare pace and pronunciation, then choose one for the full narration.

What to check before sharing

Check voice availability and provider terms, and listen to the complete rendered narration rather than judging from the preview sample alone.

Compare the final video with the current product, confirm the selected plan and provider limits, and review the preview at each format before export.

Plan a small, verifiable first use

Start with one outcome this feature should help you prepare, and decide who will judge whether it is ready. Gather only the current product context the task needs: the relevant local app folder or guide, the intended audience, and any voice, brand or format choice that affects the result. Use fictional data and keep credentials, private customer details and unreleased claims out of the brief.

Build a short representative example before preparing a larger set. Review the source and settings, then compare the script and scenes with the product behavior they describe. If the feature depends on a provider, language, plan or destination, state that dependency plainly so the reviewer can judge the right version of the output.

Review changes and pass the files along

When the first preview is ready, check the result in context: listen to the full narration, inspect captions against the audio, and preview each selected aspect ratio. Ask the product owner to verify behavior and labels; ask the publishing owner to check readability, duration and destination requirements. A successful setting or generated draft does not itself confirm that the video is accurate or ready to publish.

For handoff, include the approved MP4, subtitle files when available, the intended placement and the product version used. Keep a reviewer and review date with the asset. Revisit it when the underlying product, provider options or publishing requirements change, then rebuild and review the affected output before replacing an existing video.

Decide whether this feature fits the job

Use this workflow when a reviewed, animated explanation is useful and your team can check it against current product context. If the viewer needs to see a live-only behavior, a real person demonstrating hardware, or an interactive path they can explore themselves, consider whether a screen recording, live demonstration or interactive guide would answer the question more directly. Choose based on what the audience needs to observe.

For this feature, define a simple acceptance check before production: name the visible output that must be present and one condition that would make the draft unsuitable. That could be a required caption track, a verified provider voice, a readable mobile composition or a release-approved screen. Share that check with reviewers so feedback leads to a clear edit or approval decision.

Frequently asked questions

Which voice providers can I use?

DemoVexa documents ElevenLabs, Sarvam and Deepgram voice options, subject to account access and provider setup. You can also use your own recording or choose captions and music without a voice provider.

What should I review when using voice options for product videos?

Check voice availability and provider terms, and listen to the complete rendered narration rather than judging from the preview sample alone.

Does using this feature publish or verify my video automatically?

No. DemoVexa prepares project materials for you to review and export. A person remains responsible for checking product facts, provider limits, accessibility and destination requirements, then publishing through the chosen channel.
