3 different Alexa modules, which one is the best?

[lucallmon]

I have installed AlexaPi separate from MM 3 times with success each time. I feel like the AlexaPi I’m not sure where you guys are getting hung up. I’d be willing to walk you through it when I have time. I can do that on gitter.

@rchase said in 3 different Alexa modules, which one is the best?:
I think MMM-Alexa by sakirtemel is the best.
Because it’s pretty good from other.
Thanks :)

@romain said in 3 different Alexa modules, which one is the best?:

ncomplete instruction to me. They explain how to setup some stuff but not how to test it. So

Hi @romain , did you get to test all modules and conclude which one is the best? I am totally lost with MMM-Alexa. I installed it and can see the yellow square in the MM interface but I don’t know how to get it working. Documentation says:

" You can easily develop your own module and control this module or get notified about events happening"

But it does not say how to develop this module :(

Any clues will be greatly appreciated.

Thanks

@borrigan Hello. I end up successfully setting MMM-AlexaPi and MMM-alexa.
they both have adventages and inconvinient
-MMM-AlexaPi

• This module isn’t a stand alone module. You need to install AlexaPi on you pi ( https://github.com/alexa-pi/AlexaPi )
• This module is ONLY to show the status of AlexaPi. And this is AlexaPi that allow you to talk to Alexa. Meaning you don’t need the mirror at all to use it. But it’s neat because you can “see” what’s happening. Also Alexa saying “yes” when you say her name.
• It might or might not be easy to setting up. Some people won’t have any issue using it by following the setup instruction and other would have to tweaks some things.
• slower than MMM-alexa

-MMM-alexa

• It is a stand alone module. Meaning you just need this module to talk to Alexa.
• The square indicate you the status . yellow is bad configuration if I recall correctly. Red is ready to listen. green is listening.
• It is not activated by voice. You need either a button or to send the right notification to the module to make Alexa listen to you.
• It seem to not answer as much as MMM-AlexaPi
• You need to add https://sakirtemel.github.io/MMM-alexa/ to the allow return URL in your avs security settings of your device . And need to generate the first token by going in that first url and enter the requested information
• faster than MMM-AlexaPi

in both case I had to tweak some of my sound configurations files so my microphone is picked up and the output is my speaker.
Because MMM-Alexa needed to be activated manually or by another module (and the fact it seem to provide less answer) I think MMM-AlexaPi is better. Even though AlexaPi seem a bit slower to answer. To trigger MMM-Alexa I used the voicecontrol module (it’s a module that convert voice into notification. I set up the word “Alexa” to send the right notification to mmm-alexa) but the voicecontrol module seem to have a loooooooooot of false positive. It was activated way to much even if I didn’t talk sometime.

I didn’t successfully made mirrormirroronthewall worked though (I might try again later. I didn’t tryed since I made the other two works)
I think mirrormirroronthewall is probably the best module of all three since is suppositivly allow you to do more than the other two that only allow you to ask question to alexa and get answers from it.

as for the

But it does not say how to develop this module :(

You can either use an already existing moduel like “voicecontrol” to do that.

or developping something yourself. to do that:
You can for example take as a template the helloworld module in the ~/MagicMirror/modules/default as a template . copy/past it in the ~/MagicMirror/modules , rename the folder to something else. let’s say “toto” as an example, then rename the file inside it to match that name. helloworld.js should now be toto.js . now open the toto.js and replace all the hello words by toto.
Then delete the text: "Hello World!" and the wrapper.innerHTML = this.config.text; since you don’t need to display anything.
Now you can write this.sendNotification('ALEXA_START_RECORDING', {}); where was the wrapper.innerHTML = this.config.text;
And that send the notification to start recording what you are saying to mmm-alexa. However that example will only work once.

If you never code something before, I don’t recomand you to do the developping of a module like this yourself. It’s better to use an already existing module.

/!\ if your sound configuration isn’t good, you might not be able to use voicecontrol and mmm-alexa in the same time.
Explaining the sound configuration here would be pointless since you might not have those issue.

Thank you very very much @romain ! I will go for AlexaPi with MMM-AlexaPi. I spent all yesterday trying to set it up, and I will continue today, your input is very valuable. Just a few newbie, extra questions:

• AlexaPi service, when running, is “Always On”? It is always listening? How to test it directly without having integrated with MMM-AlexaPi Yet?

• Where can the activation word be configured? If I just say “Alexa”, should it work?

• Finally, I spent hours troubleshooting the microphone. It is a very standard Logitech Microphone. I just could not get it working.

AlexaPi service, when running, is “Always On”? It is always listening? How to test it directly without having integrated with MMM-AlexaPi Yet?

you should hear “hello” when it start and then if you say Alexa you should hear “yes” then you can ask a question. It is always listening.
A little tips for you, before using the service, try to run AlexaPi yourself. It provide you more debugging info that way.
To do it, first desactivate the service with the terminal by writing sudo systemctl stop AlexaPi.service; sudo systemctl disable AlexaPi.service (you can reactivate later by doing sudo systemctl enable AlexaPi.service).
Then you can run AlexaPi yourself by writing in the terminal /opt/AlexaPi/src/main.py -d (If you you putted it on that location anyway).

Where can the activation word be configured? If I just say “Alexa”, should it work?

in the yaml file in /etc/opt/AlexaPi/config.yaml there is a section pocketsphinx: (this is what is use to detect words I believe). in that section you have a key phrase: with "alexa" as a value. you can simply change the word to another word. Do not choose an over complicated one though, I think pocketsphinx try to guess what it supposed to sound like based on the spelling so if you choose a word not in English it might not guess correctly. You shoudl let alexa untill you get it to work though, because we know that one work for sure. You can test other word later.

Finally, I spent hours troubleshooting the microphone. It is a very standard Logitech Microphone. I just could not get it working.

I am no expert in sound but I going to try to help you.
First, I rather have the output from arecord -l rather than arecord -L . the later give to much information to my understanding.
The output of my arecord -l look like this:

pi@raspberrypi:~ $ arecord -l
**** List of CAPTURE Hardware Devices ****
card 1: Device [USB Audio Device], device 0: USB Audio [USB Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

I can see it’s “card 1” and “device 0” . that’s what I am interesting about.
then, my aplay -l give me

pi@raspberrypi:~ $ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: ALSA [bcm2835 ALSA], device 0: bcm2835 ALSA [bcm2835 ALSA]
  Subdevices: 8/8
  Subdevice #0: subdevice #0
  Subdevice #1: subdevice #1
  Subdevice #2: subdevice #2
  Subdevice #3: subdevice #3
  Subdevice #4: subdevice #4
  Subdevice #5: subdevice #5
  Subdevice #6: subdevice #6
  Subdevice #7: subdevice #7
card 0: ALSA [bcm2835 ALSA], device 1: bcm2835 ALSA [bcm2835 IEC958/HDMI]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: Device [USB Audio Device], device 0: USB Audio [USB Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

I using the default speaker output, which is the bcm2835 Alsa device which is “card 0” and “device 0”

Knowing that you can test if your device working by doing the following:
meaning you should be able to do a aplay -D hw:0,0 /usr/share/sounds/alsa/Front_Center.wav to test your speaker where “hw:0,0” (you could also put “plughw:0,0”) is your output device. Not sur what does “hw” and “plughw” mean, but the numbers are the card number and the device number. 0,0 in my example (remember the aplay -l above)
this will use the vlc handler i beleive. You can test it the same way with play instead of aplay for the sox handler.

you can test your michrophone in the same way by doing arecord -r 48000 -f S16_LE -D hw:1,0 -d 5 test.wav this will tell to record with the device hw:1,0 (in my example the card 1, device 0) for 5 second at a rate of 48000Hz and as S16_Le type (not sure what that is) and the result will be put in a file name test.wav. You can then play or aplay that file to see if the recording whent well.

If you manage to make those command work. In the /etc/opt/AlexaPi/config.yaml there is a section sound: with a key “input_device:” and a key “output_device:” . Both of those key have for value “default” . for the output it’s easy, the default is the system defautl output which is hw:0,0 in my example. so you can let default or put “hw:0,0” instead if you want to use that output like me.
The tricky part is the input. The input is your michrophone, but there is no “default” michrophone in the pi right ? so the chance AlexaPi understand what you are talking about are prett slim in my opinion.
But when I wrote “hw:1,0” or “plugwh:1,0” instead of default , I had an error. For some reason it didn’t wanted to take that value. That’s when trickery was needed for me. I’m sure some people hadn’t to do that but I did.
I creat a alsa configuration file name “asound.conf” with the following in it :

pcm.myTest {
    type dsnoop
    ipc_key 816357492
    ipc_key_add_uid 0
    ipc_perm 0666
    slave {
        pcm "hw:1,0"
        channels 1
    }
}

pcm.!default {
        type asym
        playback.pcm {
                type plug
                slave.pcm "hw:0,0"
        }
        capture.pcm {
                type plug
                slave.pcm "myTest"
        }
}

This overrite what is the “default” configuration.
type asym mean my playback and default arn’t on the same sound device.
the playback.pcm describe what is my output device. In my example you can see i putted “hw:0,0” because I use the default output.
the capture.pcm describe the input device (microphone). I put “MyTest” as a name which is describe above in the file (the name isn’t very explicit but I was testing and never changed it >.> )
I am not going to enter in the detail for the myTest thing, but basically, it’s tell that the michrophone can be use in multiple application at the time and that it is the “hw:1,0” (remember the arecord -l thing above in the post)

This asound.conf file should be put in the /etc/ folder.

Well. That’s it. That’s what I had to do to make my microphone work for AlexaPi. Adapt this to your own devices and it might work like me.
Remember to test it whitout the service first and when that’s work you activate the service and see if it still work or not. and if not we’ll try to understand why.

@romain thank you very very much for all this feedback. I was definitely missing some pieces of the puzzle. I will try this again today and post my findings here. Have a great day!

[romain]

@johnnyboy I struggle because of this @johnnyboy at first. But the lambda service is working both with us and ireland (west-eu or eu-west. don’t remember exactly now).
I end up have skill that was working. On the amazon interfaces anyway by choosing that instead of us. (even though I’m in france. I had no error anymore on the amazon test aera)
I had to change the hard coded region in the code though (easy fix).
I think I had no more error at the end (don’t remember for sure). But nothing was happening when I talked (maybe it was again a microphone issue. Not really sure about that)
I also did not understood how to use the npm start dev correctly at that time so maybe I would be able to do a better job at finding the issue now.
Maybe I try today, maybe I never try again. we’ll see (it’s not my raspberry pie I using so I am limited in when I can use it. So I rather do what I am ask to first before trying again)

[romain]

@johnnyboy Yes, But it’s not your fault. I have read an entire very long thread about mirror mirror on the wall (and maybe some others, I don’t remember if all the information were on the same spot or not) and it seem that one guy talked about trying that (changing the region) and the creator of the module himself didn’t knew Ireland was possible. But he did point out in which file the region thing was. (it wasn’t had to find though).
So I do think he meant that “that one ‘must’ be in the us-east” because he didn’t knew there was another option.
And he didn’t changed his tutorial to reflect that. (I’m guessing because he wasn’t able to test this way itself. Or maybe he wasn’t willing to)

[borrigan]

@romain hi again!!

I have done some progress. I followed your instructions, created the asound.conf file and setup myTest as the input device in the config.yaml file. When I run alexaPi, now it does not give me a microphone error, but a strange “Capture data too large” error. I get to hear the “hello” sound but when I speak “alexa” it won’t do anything.

Really weird. Here is the full output of main.py execution:

Thank you very much for your patience @romain

Best regards,

@borrigan Try to let “default” as an input device rather than myTest. The default thing will be in charge to call myTest itself (I think putting myTest directly doesn’t work for some weird reason I don’t now about)
Do you hear the “hello” when you run the script ?
If you still have the error after using the default, then ty to change you input handler from sox to vlc.I don’t think that’s related but at this point trying stuff might be the right thing x) Maybe that will fix it.

@romain finally got it working by replacing myTest with default as you indicated. Than you so very much!! One short glitch though, sometimes Alexa’s phrases can not be heard completely. For example, at boot time I can hear “o” instead of “hello”. Same happens when talking to her.

But it is working!! Now time to test MMM-AlexaPi

Thanks again @romain

[romain]

@borrigan you’r welcom =)

[borrigan]

@romain quick question, I’ve noticed that Alexa takes a few seconds to answer, sometimes around 20 seconds. Does this happen to you as well? Could it be a slow internet connection. Thanks again!

[romain]

@borrigan It happen to me as well. MMM-alexa seem a little faster but it’s a pain to use so I rather wait few second for an answer
