## What it is
Official sample code repository for the Microsoft Cognitive Services (Azure) Speech SDK, demonstrating speech-to-text, text-to-speech, and related speech features across many languages and platforms. It includes both simple getting-started examples and more complex end-to-end scenarios.

## Use cases
- add speech recognition to my app with azure speech sdk
- learn how to do text to speech with cognitive services
- sample code for azure speech sdk in c#
- convert speech to text from a microphone in python
- build a voice assistant with azure speech services
- examples of speech synthesis with custom voices
- get started with azure cognitive services speech

## When to choose
- you are building with the Azure Speech SDK and want working reference code
- you need cross-platform speech samples in C#, C++, Java, Python, JavaScript, Swift, or Objective-C
- you want to learn Azure text-to-speech and speech recognition APIs through examples

## When to avoid
- you need a production-ready speech application rather than sample code
- you want offline or self-hosted speech recognition without an Azure subscription
- you are not using Microsoft Azure Cognitive Services
