Hi Situpstraight.
I would agree that the setup of either the Google Home or the Amazon Echo speakers is certainly not straightforward. However, having had experience of both versions I have found that "once up and running" very few problems occur as they just sit there waiting for the opening command of "hey Google" or "Alexa" followed by the instruction of what you want it to do.
Therefore, my feeling would be that even with persons that have little or no IT experience, teaching the basic voice commands to operate the device should be an easy straight forward tuition experience for almost all having them installed.
In regard to areas with poor broadband speeds then 5mgps will run both Google and Amazon speakers as no graphics are involved. In the case of having to use a mobile network connection, then 3g should also suffice.
However, as the Hampshire County Council home speaker installation is in a trial phase then I would feel that at this point in time only property's with good broadband and LTE connectivity is being considered for use in the trial.
My wife and I live in a small town on the Bristol Channel coast of North Somerset. Only two years ago our broadband speeds were no better than 5-7mbps at peak times. In that, improvements have been rolling out quickly across North Somerset as is the case in many other areas of the country and speeds of 140mbps throughout the day is now standard in the majority of households. Again, as with many parts of the UK 4G LTE connection is now standard across the majority of North Somerset with EE now promising 5G speeds in the early part of next year.
As stated the trials will in all probability only be carried out in areas of good broadband and LTE connectivity and other means of support will have to be provided where that is not the case. The foregoing is the situation now for persons requiring social services support on a daily basis, but the addition of Amazon and Google speakers in suitable properties would without doubt I feel greatly improve communication and help alleviate loneliness for many.
Sufficient support for the elderly and vulnerable in our society is critical at a time of huge pressure on those providing social services for the most needy in our society. In that, innovation may prove to be hugely beneficial in maintaining that support into the future.
