Yeah we all have different opinions and requirements and what I was doing was looking at what I could do in comparison to commercially available units.
Because recognition via Google or Amazon is server based the recognition accuracy over my tests was far superior.
The beamforming and DSP that is embedded in their silicon is just missing and from echo, workplace noise we are all playing at copying a poor assimilation of the big data companies I want to beat.
Its also not $35 as by the time you get SD, PSU, case and ancillaries you quickly find yourself quite a bit above commercial product that is superior in every way apart from supposed privacy.
That due to popularity there is a rake of 2nd user models starting about $15.
That is what got me thinking about audio as I say I want to beat big data, have that privacy but this emulation of one of there products with honesty is lack lustre to say the least.
I wouldn’t use that opensource product at home, definitely not for work and the only place it has is an enjoyable builders experiment into the world of AI assistants.
In fact I am not as probably doing the same again as now playing with Peltier modules in a quest to make a near as possible silent dehumifier and likely by time I finish I will come to the conclusion the commercial guys just have me beat due to economies of sale.
The media thing wasn’t because that is how I use an assistant it was my thoughts on where I could beat big data where they are obsessed in consumer products that I can create better and also lower costs by diversification of use.
Part of the rationale for being a wifi sound system for a room is that would give me the inputs to many domestic sources that kill recognition stone dead such as hi-fi & tv.
I started seeing distributed wide array microphones being separate to true stereo audio and that a home processor is likely to be more 2001 HAL like so we can share a GPU.
In opensource we are desperately short of various audio processing algs, DSP and AI accelerators and you can build something up, but after you have there are some like me who might be more critical of what you actually have.
Its interesting and a good builders project but the reality is you can not do it for $35 and when finished apart from hobbyist/enthusiast maybe of questionable use.
So yeah we all have different opinions and some are far more critical but from the simple fact a wired mic module is far more flexible due to the flexible wires it connects on.
I don’t like the HATs at all as hard GPIO connectors just makes a whole lot of unessacarily for no advantage as if you are going to print a case you can create something far superior if you actually get choice of placement.
I actually think opensource could beat commercial offerings if it stopped copying and redesigned on diversification of use as the commercial stuff as each manufacturer wants ‘its own’ product isn’t very cost effective or interoperable and as said could be beat.
Is it that little box with a micro speaker, nope not for me and each to his own and like I say it does have everything but unless any of its actually any good what do you have?
