Why speed matters so much for dictation

Slow dictation can break your train of thought, but a fair test needs a clear start and finish. Begin timing when you stop speaking and stop when the text is ready to use, including any cleanup or correction step.

Use the same device, connection, language, and sample text for every app. Repeat the test several times and compare the median result, because cloud and device performance can vary from one run to the next.

Why AiType uses Groq

AiType uses Groq-hosted Whisper large-v3-turbo for transcription, then applies an AI cleanup pass to the completed utterance. In normal use, transcription and cleanup typically complete in about 250 ms after you stop speaking.

Actual timing varies by device, connection, language, and text length. The useful comparison is the complete speech-to-clean-text workflow, not one provider's raw model benchmark.

When on-device is faster

On-device dictation can respond quickly and can keep audio on the device. If offline use or local processing is essential, that may matter more than AI cleanup. AiType is designed for people who want cloud transcription plus a cleanup pass before the text is pasted.

Practical speed test

Use one 30-word message and measure from releasing the mic to having paste-ready text, including any editing you need to do:

Your result will depend on how quickly you speak and type, plus how much correction each tool needs. Short messages may still be faster to type.

AiType's focus: fast dictation with AI cleanup

AiType typically completes transcription and cleanup in about 250 ms, then pastes the result into the active app on desktop or makes it available in the mobile keyboard. Test it in your own workflow, because timing and cleanup needs vary.
