New language in Amazon Rekognition

I apologize, but there seems to be a misunderstanding in your question. Amazon Rekognition is an image and video analysis service that doesn't directly deal with languages in the same way that translation or natural language processing services do.

Amazon Rekognition focuses on detecting and analyzing visual content in images and videos, such as identifying objects, people, text, scenes, and activities. It doesn't have a concept of "languages" to be added or onboarded in the traditional sense.

If you're looking to add support for a new language in text detection within images, Amazon Rekognition already supports text detection in multiple languages and scripts. The service automatically detects and reads text found in images without requiring specific language selection.

If you're interested in adding new languages to AWS services that do deal directly with language processing, you might be thinking of services like Amazon Translate or Amazon Comprehend. These services periodically add support for new languages, but there isn't a public procedure for requesting new languages. AWS typically announces new language support as it becomes available.

If you have specific needs or requests regarding AWS services, the best approach is to contact AWS Support or your AWS account representative. They can provide more detailed information about current capabilities and potentially relay feature requests to the appropriate teams within AWS.
