What is voice typing?

Voice typing software lets you hold a hotkey, speak naturally, and have polished text appear in whatever app has focus — Slack, Gmail, Notion, VS Code, ChatGPT, or anything else.

It's a category that overlaps with what people used to call dictation. The difference: traditional dictation tools wrote to a single dedicated text field. Modern voice typing works anywhere you can type with a keyboard.

Modern voice typing tools follow a four-stage pipeline:

1. Audio capture. A microphone records your speech and segments it into chunks.
2. Speech recognition. A transformer model (often Whisper-family or Deepgram) converts audio chunks to a raw text transcript.
3. AI cleanup. A language model removes filler words, fixes grammar, adds punctuation, and applies tone matching for the active app.
4. Text injection. The cleaned text is inserted into the focused text field via accessibility APIs.

The whole pipeline runs in under a second on most modern hardware. Earlier dictation tools (like Apple's built-in Dictation) skip the AI cleanup step, which is why their output reads more like a raw transcript.

Voice typing tools come in two privacy postures:

• On-device: Audio never leaves your computer. Slower than cloud on older hardware, but private by default. Examples: FluidVox Local plan, Aiko, MacWhisper.
• Cloud: Audio streams to a remote server (often Azure Speech, Deepgram, or OpenAI Whisper API) for transcription. Faster on weak hardware, but requires internet and trust in the provider. Examples: Wispr Flow, Windows Voice Typing.

Some tools support both. Superwhisper and FluidVox both offer hybrid models — on-device for privacy, cloud as an option when you want speed.

• Per-app tone matching. Casual in Slack, professional in Outlook, technical in VS Code — automatically.
• Custom dictionaries. Add product names, jargon, and acronyms once; they're preserved every time.
• Multi-language support. Modern models cover 99–100+ languages including code-switching contexts.
• Voice commands. "Hey Vox, translate this to English" or "rephrase this more formally."
• File transcription. Drop an audio or video file and get a clean transcript out.
• Hands-free toggles. Sustained dictation without holding a key.

The fit depends on what you need:

• Want it free and don't need much beyond basic transcription? Use macOS built-in Dictation or Windows Voice Typing (Win+H).
• Want AI cleanup, per-app tone, custom dictionary, and cross-platform support? Compare Wispr Flow, Superwhisper, and FluidVox.
• Mostly need to transcribe recorded audio (lectures, meetings, podcasts)? Look at Aiko, MacWhisper, or FluidVox's file-transcription mode.
