Azure TTS cache

A small utility to cache the audio files generated by the Azure Text-to-Speech service.

Usage

• Build and run the service (default port is :8080 or specify with PORT environment variable)
• Make an http request to /tts with the following body:

{
  "text": "Hello world!",
  "language": "en-US",
  "name": "en-US-BrianNeural",
  "style": "chat",
  "gender": "Female",
  "azureRegion": "<region where your azure TTS instance is>",
  "azureKey": "<your azure TTS key>",
  "shouldCache": true // if set to false, the audio will be cached for 5 minutes, otherwise it will be cached indefinitely
}

• Make a GET request to /status to see the status and memory usage of the cache

Configuration

Environment variables:

• PORT: the port the service will listen on
• PERSIST_CACHE: save cache to file, default is true, if set to false the cache will be in-memory only
