I appreciate your energy 😊
There are multiple communities that have regular Discord voice:

• PAL has their MSP Waves Radio show that runs I think almost every day
• PYPT (Pump Your Post Thursday)
• Steemitgigs that does it weekely and last for over 8 hours with talks and singing
• SteemStars radio show

Team Vietnam Discord server has a voice room too but we have not yet set any program. You are more than welcome to organise something. Just come up with topics, date and time and take over the voice channel.
