Samsung Keyboard leak points to AI voice dictation in One UI 9.5

Refine Voice Input appears in a test build

Samsung may be preparing a smarter way to dictate text on Galaxy phones. According to Android Authority, citing a SamMobile report, a new option called Refine Voice Input has surfaced in an internal test build of the Samsung Keyboard app. The feature description says it is designed to clean up filler words, hesitations and similar verbal clutter.

In practice, that would work much like Gboard's Rambler voice mode on Android. Instead of transcribing every um and repeated word, the feature turns spoken ramblings into tidy, formatted text. Samsung's version would be powered by Galaxy AI rather than Google's Gemini, which drives Rambler.

The discovery comes from leaks about One UI 9.5, the next version of Samsung's software layer for Galaxy devices. It is not confirmed by Samsung itself, so the feature could still change or be dropped before release.

How Samsung's version would work

Details about the user experience come from the SamMobile report relayed by Android Authority. When the feature is enabled, the microphone icon on the Samsung Keyboard would be replaced with a Galaxy AI icon. This would signal to users that dictation is being processed by the AI system rather than plain transcription.

There are reportedly two ways to reach the feature. One is a Galaxy AI button in the bottom-left corner of the keyboard. The other is the side button on supported Galaxy phones, which could trigger the refined dictation mode directly.

As with Gboard's Rambler mode, the transcribed and cleaned-up text would appear once the user stops speaking. That flow differs from live transcription, where words appear on screen while the person is still talking.

A crowded field for AI dictation

If it ships, Refine Voice Input would put Samsung Keyboard alongside two rivals that already offer similar tools. Google's Gboard has Rambler mode, which uses Gemini to tidy up dictated speech. Microsoft's SwiftKey also has an AI voice typing feature with comparable capabilities.

Voice dictation has become a visible battleground for AI features on phones. Raw transcription often produces messy text full of filler words, so cleaning it up automatically is a practical use of on-device or cloud AI. Samsung has been adding Galaxy AI features across its software, and a keyboard-based dictation tool fits that pattern.

Because the feature was found in an internal test build, it may not be polished yet. Leaked builds frequently contain work in progress that never reaches the public.

What might come next

Android Authority notes that Samsung could introduce Refine Voice Input with the One UI 9.5 beta programme. Beta releases let enthusiasts try upcoming features before a wider rollout, so the beta could reveal whether the feature is finished and which devices support it.

Samsung has not announced the feature, and no rollout timeline is confirmed. Readers interested in the feature should wait for official details from Samsung rather than relying on the leaked build.

The leak arrives amid a series of other One UI 9.5 reports, including an upgrade to the call recorder. Together they suggest Samsung is preparing a batch of new tools for the next software release, with AI-assisted typing and dictation among them.
