[How Setup Voice Chat]

Clarification: This mod uses Discord to divide users by location.

1 - Discord Configuration

Copy your discord user id
Go to "C:\Program Files (x86)\Steam\steamapps\common\Stardew Valley\mods\LVCMod\config.json" (If you don't have it purchased on Steam, you have to look for it in the other folder you have)
Paste your user id into "DiscordUserId"
Create a Discord Server (or use and existing one)
Copy your guild ID (To be able to do this, you have to activate developer mode)
Paste your guild id into "HostDiscordServerId"

2 - Bot Configuration

Go to "https://discord.com/developers/applications"
Click on "New Application" and give your bot a name
Go to "Bot" section, and click the button that says "Reset Token"
Copy your bot token
Go to "C:\Program Files (x86)\Steam\steamapps\common\Stardew Valley\mods\LVCMod\config.json"
Paste your bot token into "HostDiscordBotToken"
And you're done! :D

[Config Voice Chat]

"DiscordUserId": It is actually used to save your user's Discord ID, anyone who has the mod will be able to access this ID (it is already public).
"HostDiscordServerId": Here you save the guild id that will be used as voice chat (Only the host of the game will be used).
"HostDiscordBotToken": This is your Discord bot token. Please be careful not to share it with anyone. (Only the match host's token is used.)
"ITalkChannelName": It is used to define which is the default chat where no one can speak and the bot will know if the player wants to use the voice chat or not. (If the voice chat doesn't exist, the bot will create a new one with the same name)
"StardewVoiceChatsCategory": It is used to tell the bot where to create all the voice chats for the locations to prevent it from creating them anywhere. (If the category doesn't exist, the bot will create a new one with the same name)
"HostSavesData": It's better if you don't touch this, but it's used to save the Discord IDs of all the users you have in your settings.

[Possible doubts]

Is the mod compatible with mods that add new localizations?

I haven't tried it, but it's supposed to.

Does the mod have a location limit?

No but yes, the only limit is the number of voice chats that discord can support on a single server

Do all players need to have the mod downloaded?

I don't know, but I imagine that if someone doesn't have it downloaded, the voice chat alone won't work for them.

Can I use the mod without a bot?

No, the bot is necessary to create the voice chats and to be able to use the voice chat.

Can I use the mod without a Discord server?

No, the mod is based on the use of Discord Guilds to create voice chats.

Why does the game crash on me?

There are several possible reasons, one is that some of the necessary data in config.json is not filled in, another is that the bot is not on your Discord server, and another is that your bot's token is incorrect.
