USB microphone and speakers for raspberry pi?

Question

Electronics

And so, there is a raspberry pi 2 B. There is a desire to make a voice assistant out of it, which will tell you the weather and find music in VK and launch it. The realization of the problems came at the moment when I realized that the microphone is connected only via USB. This is where advice is needed:
What would you stick into a raspberry so that it starts up easily, is not expensive (considering the cost of the Rassberry itself), and at the same time it is desirable not to be bulky? If you tell me where to get in St. Petersburg I will be very happy.
Well, a passing question - as far as I understand, there is no problem in connecting any speakers with 3.5?

Answer 1

USB microphones - on aliexpress for 3 bucks . There are also USB speakers for a buck
... hmm, why not buy a USB sound card for a buck ? And plug any microphone and speakers into it

Answer 2

Blue Microphones Yeti - USB, good sensitivity, can hear you without interference even on the push, and turn on the music.
