Quality Guarantee

Every localized voice app runs through a checklist and a human review, to ensure compliance with language requirements for Amazon Alexa and Google Assistant certification. Jargon guarantees that the localized apps pass the language portion of the Amazon Alexa and Google Assistant certification. In the event where modifications are required, Jargon completes them at no extra cost.

Jargon Language Localization

Frictionless Experience

Amazon Alexa Skills and Actions on Google developers securely upload the content of their voice app and specify the targeted languages. Jargon automates the process of finding translators, completing the localization, running a review process and repackaging the localized content in the same format.

Jargon Response Variation

Multi-modal and Pre-recorded Audio

Jargon's solution manages the localization process for on-screen content as well as pre-recorded audio fully eliminating the barriers for voice apps to reach global customers.

Jargon Localization Translation

Blend of Machine and Human Translation

Machine translation alone is inadequate for meeting the requirements of Alexa or Google certification. Jargon partners with professional localization networks to select native-speaking translators and reviewers, who are aided by machine translation for the optimal balance of efficiency, cost, and quality.

How to translate and localize a voice app:

Jargon Localization SDK
Step 1: Implement the Free Jargon SDK

The content structure enables Jargon to automatically ingest and parse the content and prepare it for localization

Start Building
Voice Application Content
Step 2: Upload Voice App Content

Securely share voice app content and targeted languages to receive a quote and schedule through Jargon's Conversation Platform. Once the quote is accepted, Jargon kicks off the process and sends a notification when the localized content is ready

Skill Action Certification
Step 3: Submit for Certification

The localized content is returned in a consistent format and can easily be incorporated into the voice app and submitted for certification by Amazon or Google

Voice App Localization vs Translation

Translation is defined as the rendering of words or text from one language to another whereas localization is making conversation local to a region.

Our localization service includes the various utterances a specific locale may use and expect in a voice application. When it comes to introducing internationalization of an Alexa Skill or Google Action, get started with the Jargon SDK.

With the help of Jargon, it was quick and easy to create Les Statues Musicales, the French version of Freeze Dancers. I love being able to release skills worldwide and create fun experiences for a more global audience, and the highlight of this project was seeing a video of French-speaking Alexa giving dance instructions to a group of the most adorable children.
