# Pico Text-to-Speech
|
|
|
|
The Pico Text-to-Speech (TTS) service uses the TTS binary from SVOX for producing spoken text.
|
|
|
|
You manually need to install the pico2wave binary in order for this service to work correctly. You can,
|
|
e.g., install it with apt-get on an Ubuntu system:
|
|
|
|
```bash
|
|
sudo apt-get install libttspico-utils
|
|
```
|
|
|
|
In Arch Linux the pico2wave binaries are available in an Arch User repository (AUR) under
|
|
https://aur.archlinux.org/packages/svox-pico-bin/
|
|
|
|
## Configuration
|
|
|
|
There is no need to configure anything for this service.
|
|
|
|
## Voices
|
|
|
|
The following list are the only supported languages (as these are the languages supported by
|
|
pico2wave, see also [the documentation of the Debian package](https://packages.debian.org/de/wheezy/libttspico-utils)):
|
|
|
|
```
|
|
German (de-DE)
|
|
English, US (en-US)
|
|
English, GB (en-GB)
|
|
Spanish (es-ES)
|
|
French (fr-FR)
|
|
Italian (it-IT)
|
|
```
|
|
|
|
### Default Text-to-Speech and Voice Configuration
|
|
|
|
You can setup your preferred default Text-to-Speech and default voice in the UI:
|
|
|
|
- Go to **Settings**.
|
|
- Edit **System Services - Voice**.
|
|
- Set **PicoTTS** as **Default Text-to-Speech**.
|
|
- Choose your preferred **Default Voice** for your setup.
|
|
|
|
In case you would like to setup these settings via a text file, you can edit the file `runtime.cfg` in `$OPENHAB_ROOT/conf/services` and set the following entries:
|
|
|
|
```ini
|
|
org.openhab.voice:defaultTTS=picotts
|
|
org.openhab.voice:defaultVoice=picotts:frFR
|
|
```
|
|
|
|
## Supported Audio Formats
|
|
|
|
The Pico service produces audio streams using WAV containers and PCM (signed) codec with 16bit depth.
|
|
|
|
## Caching
|
|
|
|
The Pico TTS service uses the openHAB TTS cache to cache audio files produced from the most recent queries in order to reduce traffic, improve performance and reduce number of requests.
