Talk about localization
Voice localization for content and product teams
Voice localization means making spoken content work for an audience, including its language, pronunciation, and context. Sonic generates the speech; translation, editorial review, and any timing or media assembly belong in your production workflow.
Learning and content production
Create spoken versions of approved training scripts, campaign copy, and narration. Keep a reviewed script for each locale so updates and terminology changes can be traced back to the source.
Product and customer-experience teams
Add spoken guidance to onboarding or support experiences. Test product names, navigation labels, and regional expressions in the interface where customers will hear them.
Multilingual narration and support workflows
Create spoken campaign copy, training material, support responses, and product guidance. Review the script, pronunciation, and delivery for each audience.
Give campaigns a local voice
Generate spoken versions of approved campaign copy. Choose a voice and accent for the audience, then review the delivery in context.
Bring training to more teams
Create narration for onboarding and learning materials. Update the recording when the script changes, and have a fluent reviewer check pronunciation.
Support customers in their language
Add multilingual speech to your support application. Pair it with the language understanding, translation, and business logic your workflow needs.
Make onboarding easier to follow
Add spoken guidance to product tours and setup instructions. Keep the script and terminology consistent with the localized interface.
Find the voice for each audience.
Listen to language and accent examples, then test your translated script with the voice you plan to use. Review names, terminology, and pacing with a fluent speaker.
Add Sonic to your localization workflow.
Sonic generates speech from text. Supply your translated, reviewed scripts and integrate the output into your application or media workflow. Translation, timing, and video assembly remain part of that workflow.

Review each locale before scaling production
Start with a short script that includes the words your audience will actually hear. Choose a voice, generate a sample, and have a fluent reviewer assess it in context before producing the full content set.
Explore languages and voice examples- Pronunciation: include brand names, abbreviations, numbers, and regional terms.
- Editorial fit: check meaning, tone, pacing, and whether the speech matches the translated script.
- Production fit: verify timing, audio format, and the requirements of the destination application.

Localization voice AI FAQs
Does Sonic translate the script for me?
Sonic generates speech from the text you provide. Translate and review your script before synthesis, or connect a separate translation step in your application.
How do I choose a voice for each market?
Start with the language and regional accent your audience uses. Listen to examples, then test your own script with a fluent speaker before publishing.
Can I use the audio in training or product experiences?
Sonic can generate speech for narration and applications. Review the applicable terms and voice permissions for your intended use.
Does voice localization include video dubbing?
Speech generation is one part of a dubbing workflow. Translation, timing, speaker mapping, and combining the audio with video require additional steps.
Where can I check language coverage?
The Cartesia language directory lists available languages and voice examples. Check the coverage of the model you plan to use before starting production.
What is the difference between translation and voice localization?
Translation creates text in another language. Voice localization also considers how that text sounds to the audience, including pronunciation, accent, pacing, and context. Sonic generates speech from the script you supply.
How can we keep terminology consistent across locales?
Maintain reviewed scripts and a terminology list for each locale. Generate samples containing product names and difficult terms, have fluent reviewers check them, and reuse approved choices when updating the content.
Can we update only part of a localized recording?
You can generate speech for revised text and incorporate it into your production workflow. Check the voice, pacing, and edit points against the existing audio so a partial update sounds consistent.
