Hello-Lucy

[Mykle1]

There was a problem with the HELP screen. The Commands List would display right off the bottom of the screen. I struggled with a fix for 4 days (because I am old and stupid) but then our friend on the forum, @cowboysdude, took a look at it and fixed it in 5 minutes. I am extremely grateful (and I feel even more stupid) but he did an amazing job. :-)

I’m a huge fan of MMM-SystemStats for MM running on the Pi but I’m working almost exclusively on pc/mac boards running ubuntu, now. So, I started a new module for that purpose. So far, it will identify the CPU, the CPU speed, the Total RAM, Free RAM, and each core present with each cores load by percentage. It’s a work in progress but it is functional and available to anyone that cares to try it.

Hi Miykle1,
do you know, if i can change the language of MMM-voice with Pocketsphinx / Sphinxbase to german?

I found a webseite where i can create .dic and .lm files and they work somehow (i also changed the new words in different .js files of folder MMM-voice).

I am looking forward hearing from you.

Regards

Perhaps, but you would have to ask the author of MMM-voice about that.

You say that using a usb mic on the pi is not great, because of Latency, how bad is it? Is it such that it would render the user completely disgruntled using it with Lucy?
And you say using a 3.5 jack microphone is better, albeit on a PC, etc… so I take it that this is really the best all round solution, owing to the limitations of the Pi?

Thanks

What I do remember about using voice with a usb microphone on the Pi is not the latency. It was more the limitation of voice module only allowing me to do certain things. I wanted to be able to completely control my mirror by voice. It took me a year to self-learn enough about coding to attempt Hello-Lucy.

I don’t think the latency bothered me on the Pi but it really bothered me as I was developing Hello-Lucy on a Core i7 Quad core with a USB microphone. I couldn’t understand why a 12 year old laptop with an integrated microphone performed better, until I made the realization. A $6, 3.5mm microphone made all the difference in the world. Unfortunately for Pi users. a USB microphone is your only option.

I feel compelled to say that I love the Pi. It is the reason I’ve become so involved with MM and programming, but I am realistic in my expectations of what it can do.

I have some (maybe helpful) informations about the use of microphones on RPI.
I tested this on RPI3.

I checked the difference beetween the following microphones (i had at home anyway):

1. USB Mic from Wii (Logitech)
2. USB Mic from Playstation 2 (orignal Singstar with that USB adapter inbetween)
3. USB Soundcard (USB-Audio C-Media) with 2x 3.5mm jack for microphone and speaker

Then i tried recording and playing that record to find out about the quality.
I used commands like this:
Record:

arecord /home/pi/Desktop/test_wii_mic.wav -D sysdefault:CARD=1

Play:

omxplayer -p -o hdmi /home/pi/Desktop/test_wii_mic.wav

No. 1 and 2 were terrible (it was even for a human hard to understand what words i recorded), No. 3 was very good. So my thought were to use No. 3 for different MMM-voice projects.

I hope this helps.

Thanks very much @Mykle1. I share your sentiments about the Pi. :-(
My house mirror is made such that the Pi has to be used. But with a little bit of jiggery-pokery I,m sure I can work on a really long HDMI to a hidden PC, and use a 3.5 Mic ;-)

I’ve been abroad working for a while and only just catching up on what is new on here… and really loving the idea of your Lucy. This would, for me, be the jewel in the crown :-)

So heartfelt thanks for your efforts on this, and I shall look forward to using this with utmost pleasure. :-)

@AxLed

Thanks… I just may get one of these to at least give it a try… How would you rate the performance of this, to that of using the 3.5 on a pc?

This would obviously be a much cheaper option, but only if the performance is really great compared to just the usb mic.

But as @Mykle1 noted, the Lucy graphics works best on a PC, but has given a Pi alternative, so will have a look at the two - on a Pi, and PC, and see which one suits best.

If the Pi version looks/works in a similar way to the PC version, and your suggested USB mic works great, then this may be the way to go?

Thanks.

Cool. Be sure to keep me posted. I’d also like to see some video of Hello-Lucy working on your setup when the time comes. :-)
