Large v3 Turbo ignores dictations shorter than 6-7 seconds despite enabling aggressive transcription

[AB-boi]

Description

I have noticed that dictations shorter than 6-7 seconds get the live preview transcript but then no text is actually transcribed and the overlay says No speech detected. This is troublesome as often the sentence maybe 4-5 words or just even a word.

Screen.Recording.2026-06-16.at.12.11.15-optimised.mp4

Steps to Reproduce

1. Load WhisperKit Large v3 Turbo.
2. Record a transcript shorter than 6-7s.

Nothing is entered at the cursor and No speech detected appears in the overlay.

Another thing to note is if you start recording and then say a word or two and then don't say anything and wait for 15s, the model then transcribe and enters those words (albeit with some errors appended due to the environmental sounds captured when silent).

Expected Behavior

One should be able to dictation short sentences and even single words.
