+# VoiceRSS Text-to-Speech
+
+## Overview
+
+VoiceRSS is an Internet based TTS service hosted at <https://api.voicerss.org>.
+You must obtain an API Key to get access to this service.
+The free version allows you to make up to 350 requests per day; for more you may need a commercial subscription.
+
+For more information, see <http://www.voicerss.org/>.
+
+## Samples
+
+Replace API_KEY with your personal API key for simple testing of different API calls:
+
+```
+# EN
+https://api.voicerss.org/?key=API_KEY&hl=en-us&src=Hello%20World
+https://api.voicerss.org/?key=API_KEY&hl=en-us&c=WAV&src=Hello%20World
+https://api.voicerss.org/?key=API_KEY&hl=en-us&f=44khz_16bit_mono&src=Hello%20World
+https://api.voicerss.org/?key=API_KEY&hl=en-gb&f=44khz_16bit_stereo&src=Hello%20World
+
+# DE
+https://api.voicerss.org/?key=API_KEY&hl=de-de&f=44khz_16bit_mono&src=Hallo%20Welt
+```
+
+## Configuration
+
+You must add your API_KEY to your configuration by adding a file "voicerss.cfg" to the services folder, with this entry:
+
+```
+apiKey=1234567890
+```
+
+It actually supports only one voice: "voicerss:default", which is configured to use 44kHz, mono, 16 bit sampling quality.
+
+## 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
+```
+
