Asking for the Party.
I know that most of the gadgets are text based but is there something in the short voice memos niche?
I dont believe so - LoRa is more designed for small (think tweet) text messages.
For voice, probably just want walkie talkies (since they were designed for that)
My guess was that short msgs could be compressed and exchanged. WTs are for realtime comm.
The data rate is too low - youre talking about <300 bytes per transmission
Probably the SEEED Xiao devices.
With a 6€ ESP32C6 for thread support or wifi
Or 11€ nRF52840 for ultra low powrr and bluetooth
That is at a reseller to, already with duties paid. 11-16€ is quite a hard price to beat.
It is also one of the smallest stacks you can get.
Wisblock is the go-to for great power performance while still being very small. I have heard heltecs and some others have problems if you are trying to build a really low power device due to inefficiency in power converters and such, but that is just hearsay.
