- Support Alexa Voice Service API v20160207
- Support multiple audio players: gstreamer 1.0, mpv and mpg123
- 支持Baidu 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, pocketsphinx and snowboy (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 Debian/Ubuntu/Raspbian
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
-
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

run the following python script and use the keyword
alexa
to start a conversation with alexaimport signal from voice_engine.source import Source from voice_engine.kws import KWS from avs.alexa import Alexa src = Source(rate=16000) kws = KWS(model='alexa') alexa = Alexa() src.pipeline(kws, alexa) def on_detected(keyword): print('detected {}'.format(keyword)) alexa.listen() kws.set_callback(on_detected) is_quit = [] def signal_handler(signal, frame): print('Quit') is_quit.append(True) signal.signal(signal.SIGINT, signal_handler) src.pipeline_start() while not is_quit: time.sleep(1) src.pipeline_stop()
