This video talks about what is the custom translator along with it's need. It also explains, how to create a completely customized language translator model with personalized training data and how to deploy the model in multiple Azure regions. For validating the model, C# console application was created.

In this article, I’m going to write about another interesting Azure-based service named Translator, which falls under the umbrella of Azure Cognitive Services. This service helps us to translate documents from one language to another and at the same time, it retains the formatting and the structure of the source document. So, let’s say, if any text in the source document is in italics, then the newly translated document, will also have the text in italics.
Let’s have a look at a few of the key features, of the Translator service,
- Auto-detection of the language of the source document
- Translates large files
- Translates multiple files in a shot
- Preserves formatting of the source document
- Supports custom translations
- Supports custom glossaries
- Supported document types – pdf, csv, html/htm, doc/docx, msg, rtf, txt, etc.
- Implementation can be done using C#/Python as SDKs are available. Supports REST API too.
To perform this entire translation process, here are the major steps, one needs to take care of:
The first step is to login into the Azure portal and creates an instance of the Translator service.
Clicking on Create will open up a new page, furnish all the details and click on the Review + Create button. Doing this will create an instance of a Translator service.
Grabbing the key and the endpoint of the Translator service:
Create an instance of Azure Storage service as we need to create two containers.
- The first container named inputdocs - holds source documents, which need to be translated
- The second container named translateddocs - holds target documents, which are the translated documents
Once containers are created, you could see them listed under your storage account as shown below:
Upload all the documents which need to be translated, under inputdocs container.
Next is to generate the SAS tokens for both source and target containers. Note that the source container must have at least Read and List permissions enabled, whereas the target container must have Write and List permissions enabled while generating SAS. Below are the steps to generate SAS token for the source document:
Similar steps need to be performed for the target container too.
Now comes the C# code, which utilizes all the information from the above steps:
route endpoint key json args client request data json Encoding UTF8 request Method HttpMethod Post request RequestUri endpoint route request Headers key request Content data response client request result response Content Result response IsSuccessStatusCode Console $ Console $
Step 7 - Sample input(English) and output document(French)
On executing the above C# code, you will notice that translated files got added to translateddocs container.
In this article, we have learned how to translate any document which is placed in Azure Blob to other languages. Here is the list of all the supported languages as of today. I've also recorded this entire flow on my channel, in case if you want to have a look.
Hope you enjoyed learning about Azure Translator Service.

Today I'll be mentioning one of the useful functions of Azure Text Analytics - Sentiment Analysis. Azure text analytics is a cloud-based offering from Microsoft and it provides Natural Language Processing over raw text.
Use Case Described
In this article, I will explain how to use customer-provided product reviews to understand the market insight and how one can take a call on manufacturing the products in the future. Here is the pictorial representation of this use case.
Here are the high-level steps of how we can achieve this entire flow:
