Yet Another Voice Module (Sphinx + Alexa)

@lb-rezende said in Yet Another Voice Module (Sphinx + Alexa):

-Dmaven.multiModuleProjectDirectory system property is not set. Check $M2_HOME environment variable and mvn script match.

I would verify your Maven installation. Is $M2_HOME set? If so you can -Dmaven.multiModuleProjectDirectory=$M2_HOME although this should be the default behavior.

-Dmaven.multiModuleProjectDirectory=$M2_HOME

Where do I set the $M2_HOME (and how)? I just created the maven.sh file as described in the tutorial and included the two lines. I inserted this line that you suggested in the same file, maven.sh, but did not work.
Is there a way to uninstall those applications and do all over again?

Looks like the $M2_HOME is set in the script

export M2_HOME=/opt/apache-maven-3.3.9

If the script resides in /etc/profile.d/ then it should run during boot (have you restarted your pi at all?).

Is there a way to uninstall those applications and do all over again?

Easiest would be to nuke the entire thing and start over. TBH these are linux questions and I’m very happy to support my plugin but they seem beyond the scope of that. I’ll try my best to help but may not be able to provide support on every question.

Thanks for your help. I formatted the SD card and installed all over again, but it has something that does not work.

I have Alexa working, I used the following guide:
https://github.com/alexa/alexa-avs-sample-app/wiki/Raspberry-Pi

So, following the README of your module, I have the following:
VLC:

VLC media player 2.2.1 Terry Pratchett (Weatherwax) (revision 2.2.1-0-ga425c42)

JAVA

java version “1.8.0_111”
Java™ SE Runtime Environment (build 1.8.0_111-b14)
Java HotSpot™ Client VM (build 25.111-b14, mixed mode)
javac 1.8.0_111

So ALPN is configured to 8.1.0.v20141016 (1.8.0u11 OpenJDK version)

MAVEN

Apache Maven 3.0.5
Maven home: /usr/share/maven
Java version: 1.8.0_111, vendor: Oracle Corporation
Java home: /usr/lib/jvm/java-8-oracle/jre
Default locale: en_GB, platform encoding: UTF-8
OS name: “linux”, version: “4.4.35-v7+”, arch: “arm”, family: “unix”

I configured config.js with the following sets and after that executed npm install in the module directory:

            {
                    module: 'magic-mirror-voice',
                    header: 'Magic Mirror Voice',
                    position: 'top_right',
                    config: {
                            debug: true,
                            alexa: {
                                    productId: 'my_device',
                                    dsn: '1xxxxxxxxxx'
                            },
                            ssl: {
                                    sslCaCert: '',
                                    sslKey: '',
                                    sslCert: '',
                                    sslClientKeyStore: '',
                                    sslClientKeyStorePassphrase: ''
                            },
                            companion: {
                                    port: 3000,
                                    serviceUrl: 'https://localhost:3000',
                                    redirectUrl: 'https://localhost:3000/authresponse',
                                    clientId: '.MY PRIVATE KEY',
                                    clientSecret: 'MY PRIVATE KEY'
                            },
                            client: {
                                    alpnVersion: '8.1.0.v20141016',
                                    vlcPath: '/usr/lib/vlc',
                                    vlcPluginPath: '/usr/lib/vlc/plugins'
                            },
                            sphinx: {
                                    commands: {
                                            "mirror mirror": {
                                                    action: 'alexa'
                                                    }
                                            },
                                    dictionary: './commands.dic', // Optional
                                    model: './commands.lm' // Optional
                                    }
                            }
            },

I removed the ssl optional configuration, the port is the same that is configured at the amazon developer site, the clientId and clientSecret are correct (I removed here), the ALPN version is the same of Java and the vlc address is correct, so it should be working, but I receive the following message:

MagicMirror will not quit, but it might be a good idea to check why this happened. Maybe no internet connection?
If you think this really is an issue, please open an issue on GitHub: https://github.com/MichMich/MagicMirror/issues

Do you have any idea of what is happening?

Looking through the stack trace it looks like this is unrelated to my plugin.

@whyjustin: I have integrated your module into other modules. However, am seeing the following problems:

1. Saying “mirror mirror” doesn’t trigger Alexa. Do the AVS sample apps need to be started alongside?I tried that but your module was exiting with an exception:
   Unable to run Listen in Sphinx Java Client:Error: Error running instance method
   java.lang.NullPointerException
   at com.amazon.alexa.avs.AudioCapture.startCapture(AudioCapture.java:74)
   at com.amazon.alexa.avs.AudioCapture.getAudioInputStream(AudioCapture.java:56)
   at com.whyjustin.magicmirror.sphinx.SphinxMirrorRecognizer.startRecognition(SphinxMirrorReroot@raspberrypi:/home/pi/MagicMirror/MagicMirror-master/modules/magic-mirror-voice

2. There are few errors:
   Error with Alexa Companion Service: { [Error: Not Found] status: 404 }

Please let me know where am I going wrong.

@Mirrorolentia If you can’t get that one to work or want to try a different one checkout AlexaPi. It’s a python implementation of Alexa made for all sorts of platforms.
You can get it from here: https://github.com/alexa-pi/AlexaPi

You can also use this mirror module to give status feedback on the mirror: https://github.com/dgonano/MMM-AlexaPi

Just be sure to pick the magicmirror platform during setup instead of the default raspberrypi
