Hey everyone,

We’ve overhauled our entire voice system to make dictation smoother, faster, and more reliable, especially when it comes to capturing your very first word.

Oh and Facetime works perfeclty now :)

What We Did

We rebuilt the whole voice pipeline from scratch to improve responsiveness and quality.

The Results

Instant capture from the first millisecond — Your very first word is recorded the moment you trigger the keyboard shortcut, no lag or missed beginnings.
Seamless input switching — Change your microphone mid-recording without any disruption.
Enhanced Bluetooth stability — Clearer audio and fewer dropouts with wireless devices.
Sharper speaker identification for local models — No more imaginary voices or phantom participants in meetings.

🦸The super hero trick

Did you know you can use speech-to-prompt with any selected text?

Just select a text, press and hold the mic icon or your voice shortcut, then ask Alter a question.

It works really well with requests like “explain what this means.”
