RightHand - Voice Controlled Assistant for Mac

RightHand is a voice controlled assistant for macOS, built using Go. With the power of RightHand, you can control your apps with voice commands, making your workflow smoother and more efficient. Whether it's opening a file, navigating through your apps, or even controlling your music player, everything can be done by your voice.

RightHand leverages several powerful libraries such as robotgo for simulating keyboard input, whisper for voice recognition, macdriver for creating macOS applications using Go, and langchaingo for Language Learning Model interpretation. This software uses OpenAI's GPT-4 model to interpret transcriptions and generate corresponding commands.

Righthand uses the lovely macdriver project to enable MacOS api interactions.

Motivation

Two weeks before initially publishing this I got into a pretty bad mountain biking accident. I built this for myself to better use my computer with a mix of one-handed typing and voice control.

Features

1. Voice Recognition: Leveraging the whisper model, RightHand can accurately transcribe spoken words into text.
2. Natural Language Understanding: RightHand uses langchaingo with OpenAI's GPT-4 model to understand the context of your speech and execute relevant actions.
3. Contextual Awareness: RightHand adapts its responses based on the currently active application, providing a tailored user experience.
4. Hands-Free Control: Perform actions such as opening files, navigating through apps, controlling media playback, and more using just your voice.

Installation

Dependencies:

• Go
• portaudio

Ensure that Go is installed on your machine. To install RightHand, run:

$ go install github.com/tmc/righthand@main

Usage

$ righthand

You can toggle the listening state of RightHand by pressing the control key while holding down the command key. RightHand will start transcribing your speech, interpret it, and execute commands on the active application.
