Introduction

This demo utilizes Azure OpenAI and Azure AI Foundry Text-To-Speech (TTS) service. It acts as a language tutor that assists users to study new languages.

Workflow

0. User needs to configure the Azure OpenAI (OpenAI Key, deployment, OpenAI Account) and Speech Service (SpeechKey, region)
1. The program takes input from the user.
2. The input is sent to the Azure OpenAI model.
3. The response is then returned as text.
4. The text is sent to TTS Service and a voice is being played.

Prerequisites

• A deployment and endpoint on Azure OpenAI. See Azure OpenAI in Foundry Models.
• A subscription key for the Speech service. See Try the speech service for free.
• A PC with a working speaker or headset. See the Speech SDK installation quickstart for details on system requirements and setup.
