What is Voice Input?
The basics
Voice input (also called voice typing, voice dictation, or speech-to-text) lets you type by speaking into your computer's microphone. Your speech is transcribed to text and inserted into whatever application you're using.
Modern voice input has two stages:
- Speech-to-Text (STT) — converts your audio into raw text transcription
- AI Text Polishing — an LLM removes filler words, fixes grammar, and formats the text
OpenTypeless combines both stages into a single hotkey press. You speak, and polished text appears in your app seconds later.

Tips for Better Voice Input
Get the most out of dictation
Use a decent microphone
A USB headset or decent built-in mic makes a big difference. Background noise is the #1 enemy of accuracy.
Speak in complete sentences
Short phrases work, but complete sentences give the LLM more context for better polishing and grammar correction.
Customize your polishing prompt
The default prompt works well, but you can customize it for your use case — formal emails, casual chat, code comments, etc.
Build your custom dictionary
Add project-specific terms, names, and acronyms. This prevents the STT from misrecognizing your domain vocabulary.
Alternate between typing and voice
Use voice for long-form content and typing for quick edits. This reduces strain and maximizes productivity.
