# Mary Text-to-Speech
|
||
|
|
|
||
|
|
## Overview
|
||
|
|
|
||
|
|
The Mary Text-to-Speech (TTS) service is a pure Java implementation of a TTS service, which uses the [MaryTTS](http://mary.dfki.de/) project of DFKI.
|
||
|
|
|
||
|
|
While it provides good quality results, it must be noted that it is too heavy-weight for most embedded hardware like a Raspberry Pi. When using this service, you should be running openHAB on some real server instead.
|
||
|
|
|
||
|
|
## Configuration
|
||
|
|
|
||
|
|
There is no need to configure anything for this service.
|
||
|
|
|
||
|
|
## Voices
|
||
|
|
|
||
|
|
MaryTTS comes with three packages voices, one for American English, two for German:
|
||
|
|
|
||
|
|
```
|
||
|
|
> voice voices
|
||
|
|
marytts:cmuslthsmm cmu-slt-hsmm (en_US)
|
||
|
|
marytts:bits3hsmm bits3-hsmm (de)
|
||
|
|
marytts:bits1hsmm bits1-hsmm (de)
|
||
|
|
```
|
||
|
|
|
||
|
|
## Supported Audio Formats
|
||
|
|
|
||
|
|
The MaryTTS service produces audio streams using WAV containers and PCM (signed) codec with 16bit depth.
|
||
|
|
The sample frequency depends on the chosen voice and ranges from 16kHz to 48kHz.
|
||
|
|
|
||
|
|
## Log files
|
||
|
|
|
||
|
|
The log messages of Mary TTS are not bundled with the openHAB log messages in the `openhab.log` file of your log directory but are stored in their own log file at `server.log` of your log directory.
