Supported Audio Formats

It supports the following audio formats: MP3, OGG, AAC and WAV.

Caching

The VoiceRSS extension does cache audio files from previous requests, to reduce traffic, improve performance, reduce number of requests and provide same time offline capability.

For convenience, there is a tool where the audio cache can be generated in advance, to have a prefilled cache when starting this extension. You have to copy the generated data to your userdata/voicerss/cache folder.

Synopsis of this tool:

Usage: java org.openhab.voice.voicerss.tool.CreateTTSCache <args>
Arguments: --api-key <key> <cache-dir> <locale> { <text> | @inputfile }
  key       the VoiceRSS API Key, e.g. "123456789"
  cache-dir is directory where the files will be stored, e.g. "voicerss-cache"
  locale    the language locale, has to be valid, e.g. "en-us", "de-de"
  text      the text to create audio file for, e.g. "Hello World"
  inputfile a name of a file, where all lines will be translatet to text, e.g. "@message.txt"

Sample: java org.openhab.voice.voicerss.tool.CreateTTSCache --api-key 1234567890 cache en-US @messages.txt
