You can trade range for bandwidth by playing with the spread factor, an encoding tunable: https://meshtastic.org/docs/configuration/radio/lora/#modem-preset https://meshtastic.org/docs/configuration/radio/lora/#modem-... But generally yes, latency is too high and bandwidth is too low for synchronous voice. The upside is that real-world performance often exceeds the range of analog UHF even at significantly lower frequencies, e.g. GMRS.
