I have a Raspberry PI model B+ and I was thinking of integrating it to Alexa Voice Service. So I was able to manage my Raspberry PI and Alexa Voice Service until the part that Alexa says hello. In order to achieve this I used also PC108 media USB external sound card. So I’m getting both input and output from my plug-in microphone or my mini jack audio output to speaker. The thing is that something is missing in order to work .What do I have to do in order to make Alexa listen ?
Thank you in advance.
At re:Invent 2016 they had a workshop on doing this. Take a look at the slides from the session and the workshop instructions. We used a simple USB microphone and sound is built into the Pi. The sample app is still being updated so it should be good to go.
This was with a Pi3 but the basics should still be the same.
You can also use PiCroft that is an image of Mycroft a open source assistant it's just burn it on a sdcard and use

I have a raspberry pi 4 with a camera module on it and a pan-tilt hat.
I've made a project which when started, it uses the feed from the RPI camera, detects a face and center around it. If the person moves, the camera tracks him.
When I run the .py file through the terminal, it works.
Now I want to use it with my PC. Therefore, I need to simultaneously run my project in the background AND to steam the feed to my PC somehow.
From the methods I searched online, I saw that it's possible to use flask and get a URL to use as an IP camera.
My question is, is it possible to stream the camera feed while my projects runs and tracks the face?
Thank you.
I have camera (camera + videoprocessor TW8834) sending video data over bt656 protocol, but the camera interface have not i2c on cable, so, it isn't recognizing by linux video driver.Is there some way to capture video from my camera in linux without modifieng the video driver?
I got advice to make a fake probe in the existing video driver (sun6i), but i don't think that it is the optimal way. May be i can write some driver or something simmilar that will snap up i2c messaging with my camera? Can i use it with default video driver by this way?
May be, are there some other way?
What should i learn to solve my problem?
I solve my problem by driver and DeviceTree modification. OS Armbian, easy to build, easy to make and apply patches. Big community. Some course about kernel hacking, which was usefull for me: https://courses.linuxchix.org/kernel-hacking-2002.html
For create solution we with my collegue spend about 4 days, we both was non-experienced in kernel modification earlier. I hope, this information will help someone with similar problem.
I am very new to raspberry pi. I want to use annyang speech recognition software (it is a speech recognition software for websites). But I am not understanding how to start working with microphone. (When I use arecord or aplay commands, it is showing error such as: No such file in directory).
Do I need to change any settings in the pi board to access microphone?
Raspberry pi's do not have a built in microphone, you will need to use a USB microphone or connect a USB Sound Card and plug a microphone into that.
When you use arecord you will probably have to tell it to use the right device with a command similar to this:
arecord /home/pi/Desktop/a.wav -D sysdefault:CARD=1
I'm looking for a way to capture pictures or video from my entry-level GoPro using the command line and with the camera connected via USB. There're lots tutorials of how to do it with the goPros that have Wi-Fi. Is there any way to do it like we do with webcams?
None of the GoPros support live streaming via USB. USB is primarily used for charging camera and access SD card. You simply cannot live stream from entry-level GoPro.
I have a few questions about Motion-MMAL for the Raspberry Pi B+ model, running on Raspbian: Sorry if these are noob questions.
1) I want to disable the live stream capability completely; however, i can only find information on how to keep the live stream local
2) If I do not visit the local address for the live stream, is it still technically uploading data and live streaming?
I think if you comment out the webcam_port value in motion.conf then you will not be streaming. Default is 0 for disabled.
So motion will still be recording video if there is actual motion. Nobody will be able to view a live stream.
