This toolkit is used to interact with the Azure Cognitive Services API to achieve some multimodal capabilities. Currently There are four tools bundled in this toolkit:
  • AzureCogsImageAnalysisTool: used to extract caption, objects, tags, and text from images. (Note: this tool is not available on Mac OS yet, due to the dependency on azure-ai-vision package, which is only supported on Windows and Linux currently.)
  • AzureCogsFormRecognizerTool: used to extract text, tables, and key-value pairs from documents.
  • AzureCogsSpeech2TextTool: used to transcribe speech to text.
  • AzureCogsText2SpeechTool: used to synthesize text to speech.
  • AzureCogsTextAnalyticsHealthTool: used to extract healthcare entities.
First, you need to set up an Azure account and create a Cognitive Services resource. You can follow the instructions here to create a resource. Then, you need to get the endpoint, key and region of your resource, and set them as environment variables. You can find them in the “Keys and Endpoint” page of your resource.

Create the Toolkit

from langchain_community.agent_toolkits import AzureCognitiveServicesToolkit

toolkit = AzureCognitiveServicesToolkit()

[tool.name for tool in toolkit.get_tools()]

['Azure Cognitive Services Image Analysis',
