Kaiju Hub AI

Voice Typing

Voice Typing service selection in Kaiju Hub settings

Overview

Choose a local transcription engine or your operating system's built-in dictation service. Availability depends on your platform and which optional engines are installed.

What speech-to-text does

Speech to text turns what you say into editable text wherever Kaiju Hub AI offers a microphone action. Use it to dictate agent prompts, continue a Kaiju Voice conversation, and enter longer instructions without typing. Local engines such as Whisper and Parakeet keep transcription on your machine; platform dictation uses the speech service provided by Windows or macOS.

Parakeet and Insanely Fast Whisper

Optional fast engines

These engines are separate downloads so the default installation stays small. The settings screen shows installation and hardware status for each engine.

See words stream into your prompt as you speak with live local transcription. Insanely Fast Whisper is optimized for modern NVIDIA GPUs, with Whisper, Parakeet, cloud, and platform speech options also available.

NVIDIA Parakeet

A high-speed local speech-to-text engine. Install its optional runtime from the Voice Typing settings before selecting it.

Insanely Fast Whisper

An accelerated Whisper implementation intended for compatible GPU systems. Install the optional engine before use.

Selecting one through Kaiju Voice never starts a large download silently. Install it in Settings first; the assistant can then verify availability and switch services.
