    Alexa

    Amazon Alexa home assistant

    With three sensitive microphones, it is possible to recognize speech from a distance of up to 5 meters, which makes it easy to integrate the device with Amazon Alexa, ChatGPT, Google Home, and other voice control systems.


     

    In the version with the pan-tilt camera, facial detection and tracking allow for activation with just a glance (without the need to speak wake words like "Alexa" or "OK Google"). An example of this can be seen in the demonstration video (see Camera Pan/Tilt).
     

    You can easly setup Amazon Alexa on SaraKIt using prepared repository 

    Register an AVS device

    Before you can use the SDK, you must register an AVS device on the Amazon developer portal by following the instructions on Register an AVS Product and Create a Security Profile. After registering your device, you download a config.json file. This file contains your client ID and client secret. The client ID and client secret authorize your device to retrieve access tokens from AVS. Your config.json file facilitates the authorization calls between AVS and your device. Save your config.json file somewhere accessible. You need to use it later in this tutorial to build and authorize your instance of the SDK.

    Build Amazon Alexa sample

    Clone repository to /home/pi/  and go to SaraKIT/Alexa

    cd SaraKIT/Alexa

    create necesearry directories

    mkdir install build && cd build

    cmake project

    cmake ../AVS
-DGSTREAMER_MEDIA_PLAYER=ON
-DPORTAUDIO=ON
-DPORTAUDIO_LIB_PATH=/home/pi/saraKIT/third-party/portaudio/lib/libportaudio.so
-DPORTAUDIO_INCLUDE_DIR=/home/pi/saraKIT/third-party/portaudio/include
-DPORCUPINE_KEY_WORD_DETECTOR=ON
-DPORCUPINE_KEY_WORD_DETECTOR_LIB_PATH=/home/pi/saraKIT/third-party/porcupine/libpv_porcupine.so
-DPORCUPINE_KEY_WORD_DETECTOR_INCLUDE_DIR=/home/pi/saraKIT/third-party/porcupine/include
-DCMAKE_INSTALL_PREFIX=../install
-DBUILD_TESTING=OFF

    make project

    make -j4 && make install

    Set up your SDK configuration file go to AVS\tools\Install and run 

    ./genConfig.sh config.json 12345
/home/pi/saraKIT/Alexa/db
/home/pi/saraKIT/Alexa/AVS
/home/pi/saraKIT/Alexa/build/Integration/AlexaClientSDKConfig.json
-DSDK_CONFIG_MANUFACTURER_NAME="saraKIT"
-DSDK_CONFIG_DEVICE_DESCRIPTION="saraKIT"

    run sample:

    PA_ALSA_PLUGHW=1 ./SampleApp ./AlexaClientSDKConfig.json /home/pi/saraKIT/third-party/porcupine DEBUG9
