Yet Another Voice Module (Sphinx + Alexa)

d3r

@clumsy_ninja This module has no visual feedback. You only get an audio prompt which indicates that alexa is listening and a second audio prompt when the audio stops.

clumsy_ninja

@d3r Thanks. I’ve been looking at AlexaPi and i’m not sure how similar the code is but i did notice is has led’s indicating the status (listening, processing, speaking).
https://github.com/alexa-pi/AlexaPi

What i really want to achieve is a module for the mirror which shows the visual feedback with a microphone icon and also show the GUI cards alexa service returns. Problem is I’m not sure how to make this hahah I’m only use to writing in C and Java.

IIRC I exposed some of this stuff in the plugin, it shouldn’t be too hard to provide UI feedback for these events. Look at the events passed to the Java client here: https://github.com/whyjustin/magic-mirror-voice/blob/master/node_helper.js#L49. If you get anything working, PRs welcome.

GUI Cards are going to take more work.

@whyjustin Thanks for that, I’m new to javascript myself but I’m trying to recruit a mate to give us a hand haha. I’ll post something back if I get anything working.

@whyjustin Is it possible to change the activation work in your alexa? I remember seeing it defined in json somewhere but does it require voice training or something?

Hi,

I’m having a problem installing this module and maybe someone could help me, because this is my first experience with Linux and the Magic Mirror.

I followed the link describe in the Github to install Alexa. It was everything ok, I talked to her at the end.

I followed the rest of the instructions to install the module, although when I start the Magic Mirror it keeps at “loading” and after a while the application crash.

The last message is:
Listening for transport dt_socket at address: 5005
electron js/electron.js: …/src/java.cpp:105: v8::Localv8::Value Java::ensureJvm(): Assertion `result->IsNull()’ failed.

How can I solve it?

Thanks in advance.

     commands: {
        "mirror mirror": {
          action: 'alexa'
        }
      },

If you edit the above you can adjust the activation of Alexa. Haven’t spent much time with this project recently but IIRC you have to remove sphinx-model-generator/commands.dic and sphinx-model-generator/commands.lm when changing the commands.

If I were to hazard a guess the JDK isn’t installed on your machine although you previously said that you were able to verify Alexa was working. Wild guess would be to verify the steps in [0] were followed to downgrade the electron client although this may not be related.

I had done that step when I installed. I checked again, and Alexa is working when I execute the last step of the installation process (the one that has to open three different terminals and then the Alexa opens).

As I said, I’m new with Linux, so probably I configured it with something missing or wrong. My config.js is this way:

            {
                    module: 'magic-mirror-voice',
                    header: 'Magic Mirror Voice',
                    position: 'top_right',
                    config: {
                            debug: true,
                            alexa: {
                                    productId: 'MagicMirrorEmmanuel',
                                    dsn: 'MagicMirrorEmmanuel'
                            },
                            ssl: {

                            },
                            companion: {

                            },
                            client: {
                                    alpnVersion: '1.0.2',

                            sphinx: {

                                            "mirror mirror": {
                                                    action: 'alexa'
                                                    }
                                            },
                                    dictionary: './commands.dic', // Optional
                                    model: './commands.lm' // Optional

                            }
            },

I’m not sure about the alpnVersion, vlcPath and vlcPluginPath, because I do not know where and how to find it. The dsn line as well, where do I find it?
I already changed ports as discussed here before, but did not work.

Thanks!

Verify your java version by running java -version then you should be able to look up the ALPN here. Your version looks incorrect so maybe this is your issue.

vlcPath and vlcPluginPath,

Check the docs here, but it should boil down to running whereis vlc. The values you provided look correct for a default setup.

because I do not know where and how to find it. The dsn line as well, where do I find it?

I don’t think you need to worry about this. It’s part of the automated cert generation and the communication between the OAuth NodeJS server and the Alexa Java application. IIRC this can be any value.

@whyjustin Yeah thats it. Do i need to record a new training file to replace those or where did the original one come from?

lb-rezende

@whyjustin

I followed this doc that you linked and it has more details than the original readme file that I used, when I used the automated installation. The problem now is that Maven is no longer working. I receive the following message:

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

Any idea how to solve it?

The plugin will automatically generate your models and dictionary on startup using the JSON property names (e.g. “mirror mirror”) if the sphinx-model-generator/commands.dic and sphinx-model-generator/commands.lm are missing. So remove those files, adjust the JSON, then start the plugin again. You can also manually edit the commands.lm and commands.dic files after they are automatically generated if you are comfortable with language modeling.

whyjustin

@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.

lb-rezende

@whyjustin said in Yet Another Voice Module (Sphinx + Alexa):

-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?

whyjustin

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

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.

lb-rezende

@whyjustin

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:

                            companion: {
                                    port: 3000,

                            client: {
                                    alpnVersion: '8.1.0.v20141016',

                            },
                            sphinx: {

                            }
            },

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:

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:

@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
