Code reveals Google Translate Android app testing 'Smart assist' to clean voice input before translation

Tech media outlet Android Authority discovered traces of a new "Smart assist" feature by decompiling version 10.39 of the Google Translate Android app on October 9.

The feature aims to preprocess user voice input before translation, automatically removing filler words like "um" and "uh" as well as repeated corrections, sending only the cleaned text to the translation model. Current code clues suggest this option may be available only in "Conversation mode," while it appears disabled in "Listening mode" and text-only modes.

This follows previous iterations such as the introduction of Gemini real-time translation in 2025 and background real-time translation in 2026. Note that this is unannounced leaked information; the final release form and scope may change.
