ovos-audio 0.2.1

ovos-core audio daemon client

ovos-audio

The "mouth" of the OVOS assistant!

Handles TTS generation and sounds playback

Install

pip install ovos-audio[extras] to install this package and the default plugins.

Without extras, you will also need to manually install, and possibly configure TTS modules as described below.

Configuration

under mycroft.conf

{

  // Text to Speech parameters
  "tts": {
    "module": "ovos-tts-plugin-server",
    "fallback_module": "ovos-tts-plugin-mimic",
    "ovos-tts-plugin-mimic": {
        "voice": "ap"
    }
  },

  // File locations of sounds to play for system events
  "sounds": {
    "start_listening": "snd/start_listening.wav",
    "end_listening": "snd/end_listening.wav",
    "acknowledge": "snd/acknowledge.mp3",
    "error": "snd/error.mp3"
  },

  // Mechanism used to play WAV audio files
  "play_wav_cmdline": "paplay %1 --stream-name=mycroft-voice",

  // Mechanism used to play MP3 audio files
  "play_mp3_cmdline": "mpg123 %1",

  // Mechanism used to play OGG audio files
  "play_ogg_cmdline": "ogg123 -q %1"
}

Using Legacy AudioService

The legacy audio service supports audio playback via the old mycroft api (@mycroft @ovos)

by default OCP acts as a translation layer for this api and no action is needed, but if you want to disable ocp this api remains available

NOTE: once ovos-media is released OCP and this api will be disabled by default and deprecated!

{
    "enable_old_audioservice": true,
    "disable_ocp": true,
    "Audio": {
        "default-backend": "vlc",
        "backends": {
          "simple": {
            "type": "ovos_audio_simple",
            "active": true
          },
          "vlc": {
            "type": "ovos_vlc",
            "active": true
          }
        }
    }
  },
}

legacy plugins:

• ocp
• vlc
• simple (no https support)

OCP technical details:

• OCP was developed for mycroft-core under this legacy system
• OCP will pose as a legacy plugin and translate the received bus events to the OCP api
• OCP is always the default audio plugin, unless you set "disable_ocp": true in config
• OCP uses the legacy api internally, to delegate playback when GUI is not available (or configured to do so)
• this does NOT bring support for old Mycroft CommonPlay skills, that is related to skills service not ovos-audio
• this brings support for OCP skills to OVOS until ovos-media is finished
• ovos-media will fully replace OCP in ovos-audio 0.2.0
