Code Block
1. Initialize and download the code base - Example for RaspberryPi: (we can use rdkv.xml to build with external source method or rdkv-nosrc.xml to build without externalsrc) $ repo init -u https://code.rdkcentral.com/r/manifests -m rdkv-nosrc.xml -b rdk-next $ repo sync 2. Download the meta-rdk-voice layer in project root $ git clone https://code.rdkcentral.com/r/components/generic/rdk-oe/meta-rdk-voice 3. Enable the below DISTRO feature to build AVS plugin $ vi meta-rdk-voice/conf/layer.conf - enable the below commented line #DISTRO_FEATURES_append = " alexa-plugin" 4. For the external source builds (such as some Broadcom platforms) add below line in manifest/auto.conf - In <Manifest>.xml <project name="components/generic/avs/alexa_skill_mapper" revision="rdk-next"/> - In auto.conf (where brcmexternalsrc is enabled) BRCMEXTERNALSRC_pn-wpe-alexaskillmapper += "components/generic/avs/alexa_skill_mapper" SRCPV_pn-wpe-alexaskillmapper = "${BRCMEXTERNAL-SRCPV-CMF}" $ repo sync

4. if wanted to use MIC based implementation (Ignore if using BLE voice remote) $ vi meta-rdk-voice/conf/layer.conf - enable the below commented line #DISTRO_FEATURES_append = " alexa_ffv"

...

Keyword detector (KWD) support enables the device to wake-up & listen to input after receiving the hot word "Alexa". It is used with devices that has on-board Microphonehas on-board Microphone

This option need to be enabled along with "alexa_ffv" DISTRO for MIC based voice input

Code Block
1. To use pryon lite KWD engine for devices with MIC input Note: Source code need to be obtained from amazon separately 2. Set the KWD support flag to "ON" $ vi meta-rdk-voice/recipes-wpe/wpeframework/include/avs.inc AVS_KWD_SUPPORT ?= "ON" 3. include the KWD detector recipe to build. - enable the commented line #PREFERRED_PROVIDER_virtual/alexa-kwd-detector = "pryonlite" 4. Create a bbappend file in platform layer and provide artifact location e.g. $ vi meta-rdk-oem-<OEMNAME>/meta-<MACHINE>/recipes-avs/pryonlite/pryonlite_2.3.0.bbappend SRC_URI = "file://pryon_lite_2.3.0-metrological-2019.12.23.2344.zip"
