Voice Commands provide quick, context-aware actions you can trigger through voice input, complementing the full Voice Agent experience.

​
Overview

While the Voice Agent provides conversational AI interaction, Voice Commands offer instant execution of predefined actions through simple voice triggers.

​
Global Voice Shortcuts

​
Primary Voice Controls

Voice Agent

Ctrl+Alt+JLaunch the full Voice Agent for conversational AI interaction

Voice Transcription

Ctrl+Alt+TToggle voice-to-text transcription mode

Cycle Transcribe Modes

Ctrl+Shift+TSwitch between paste, typewriter, and buffer modes

Stop Auto-typing

Ctrl+Shift+XImmediately halt any ongoing AI typing

​
Built-in Voice Actions

These actions are available when the Voice Agent is active:

​
System Commands

Voice trigger: “Change the theme to [light/dark]”Switches the Tabby interface between light and dark mode.
{
  name: 'changeBrowserTheme',
  type: 'function',
  description: 'Change the browser theme',
  parameters: {
    type: 'object',
    properties: {
      theme: {
        type: 'string',
        enum: ['light', 'dark']
      }
    },
    required: ['theme']
  }
}
Voice trigger: “End conversation” / “Hang up” / “Goodbye”Gracefully ends the voice session and closes the agent.
{
  name: 'endConversation',
  type: 'function',
  description: 'End the current voice conversation',
  parameters: {
    type: 'object',
    properties: {},
    required: []
  }
}

​
Desktop Automation Commands

When Windows MCP is enabled, these voice commands are available:
​
Open Applications
voice
“Open Chrome” / “Launch VS Code” / “Start Notepad”Uses Powershell-Tool to launch applications quickly.
​
Switch Applications
voice
“Switch to Chrome” / “Focus on VS Code”Uses App-Tool to activate running applications.
​
Close Applications
voice
“Close Chrome” / “Quit Notepad”Uses process management to terminate applications.

​
Workflow Automation

Create custom voice-triggered workflows by training the Voice Agent:
1

Describe Your Workflow

Tell the agent about your routine:“Every morning I open Slack, Gmail in Chrome, and VS Code with my project folder.”
2

Agent Stores as Memory

The agent saves this as a procedural memory with type PROCEDURAL.
3

Trigger Workflow

Next time, just say:“Prep my workspace” / “Start my day” / “Set up my environment”The agent executes the stored workflow automatically.

​
Example Workflows

User: "When I say 'dev mode', open VS Code in my projects folder, 
       start the terminal, and open Chrome with localhost:3000"

[Agent stores workflow]

User: "Dev mode"
[Agent executes all steps]

​
Memory-Based Commands

The Voice Agent remembers context across sessions:
Example: After telling the agent your name is Sarah:User: “What’s my name?”Agent: “Your name is Sarah.”The agent searches memories first before responding to any query.
Example: After expressing preference:User: “I prefer dark mode”[Agent stores preference]Later: “Set my theme”[Agent applies dark mode based on stored preference]
Example: Sharing your tech stack:User: “I work with React, TypeScript, and Tailwind CSS”[Agent stores technical preferences]Later: “Create a new component”[Agent generates React + TypeScript + Tailwind component]

​
Creating Custom Commands

You can extend voice commands by adding custom tools to the MCP server or creating new functions in the Voice Agent API.

​
Custom Tool Template

{
  type: 'function',
  name: 'customAction',
  description: 'Description of what this action does',
  parameters: {
    type: 'object',
    properties: {
      param1: {
        type: 'string',
        description: 'Description of parameter'
      }
    },
    required: ['param1']
  }
}
Add your tool to DEFAULT_VOICE_TOOLS array in /lib/ai/voice/index.ts.

​
Tool Execution Handler

Implement the execution logic in the Voice Agent hook: 
case "customAction":
  // Your custom logic here
  console.log(toolArgs.param1);
  // Perform action
  break;

​
Command Best Practices

For reliable voice command recognition:
  1. Be specific: “Open Chrome” vs “Open browser”
  2. Use natural language: “What’s the weather?” vs “Weather query”
  3. Avoid ambiguity: “Open my main project” (after teaching the agent which project)
  4. Build context: Let the agent learn your preferences over time
  5. Confirm actions: The agent will acknowledge and execute

Troubleshooting

  • Check microphone permissions in browser settings
  • Verify microphone is selected as default input device
  • Test microphone in browser console: navigator.mediaDevices.getUserMedia({ audio: true })
  • Reduce background noise
  • Ensure Windows MCP server is running (for desktop automation)
  • Check API keys are properly configured
  • Verify memory backend is accessible at localhost:8000
  • Review browser console for error messages
  • Confirm memory backend is running
  • Check Supabase connection for vector storage
  • Verify Neo4j connection (if using knowledge graph)
  • Try explicitly saying “Remember that” after sharing information

​
Requirements

Voice Commands require:
  • OpenAI API key (for Voice Agent)
  • Groq API key (for Transcription)
  • Microphone permissions
  • (Optional) Windows MCP server for desktop automation
  • (Optional) Memory backend for persistent context
