• Support Alexa Voice Service API v20160207
• Support multiple audio players: gstreamer 1.0, mpv and mpg123
• 支持DuerOS

Choose a player from mpv, mpg123 and gstreamer. SpeechSynthesizer and Alerts prefer mpg123 as it is more responsive. AudioPlayer likes gstreamer > mpv > mpg123. Gstreamer supports more audio format and works well on raspberry pi. We can also specify the player of AudioPlayer using the environment variable PLAYER.

• one of mpg123, mpv and gstreamer 1.0
• python-pyaudio
• respeaker python library and pocketsphinx (optional, for hands-free keyword spotting)

If you use raspberry pi and gstreamer, it is likely that gstreamer's default audio sink is GstOMXHdmiAudioSink. It ignores ALSA configurations and outputs audio to HDMI. If you don't want to use HDMI audio output, you should run sudo apt remove gstreamer1.0-omx gstreamer1.0-omx-rpi

• For ReSpeaker Core (MT7688)

  gstreamer1.0, pyaudio and pocketsphinx and respeaker python library are already installed by default, just run pip install avs

• For Ubuntu/Debian

  sudo apt-install mpg123 mpv sudo apt-get install gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly
  gir1.2-gstreamer-1.0 python-gi python-gst-1.0 sudo apt-get install python-pyaudio sudo pip install avs respeaker pocketsphinx # requires gcc toolchain and libpulse-dev

1. run alexa-audio-check to check if recording & playing is OK. If RMS is not zero, recording is OK, if you can hear alarm, playing is OK

   $alexa-audio-check RMS: 41 RMS: 43

2. run alexa-auth to login Amazon, it will save authorization information to ~/.avs.json

3. run alexa-tap, then press Enter to talk with alexa

4. run alexa, then use "alexa" to start with conversation with alexa, for example, "alexa, what time is it"

If you want to use a specified player, use the environment variable PLAYER to specify it, such as PLAYER=mpv alexa-tap or PLAYER=mpg123 alexa or PLAYER=gstreamer alexa

• Speaker interface
• Notifications interface

If you want to use your own client id and product id, try:

1. register for an Amazon Developer Account

2. create a file named config.json with your product_id, client_id and client_secret

   { "product_id": "x", "client_id": "y", "client_secret": "z" }

3. run alexa-auth -c config.json

4. run alexa-tap or alexa
