# 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> <voice> { <text> | @inputfile } [ <codec> <format> ]
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"
voice the voice, "default" for the default voice
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"
codec the audio codec, "MP3", "WAV", "OGG" or "AAC", "MP3" by default
format the audio format, "44khz_16bit_mono" by default
Sample: java org.openhab.voice.voicerss.tool.CreateTTSCache --api-key 1234567890 cache en-US default @messages.txt
