A NOTE FROM NATIVEFLOW

How the lab works.

Enter a phrase, choose an accent and listen. Select highlighted words to explore patterns that may occur in connected speech.

01
Real speech, generated for your text.

Two Cloudflare Workers AI voices can synthesize your sentence. They are AI-generated, not recordings of a person, and may sound more like reading than casual conversation.

02
Possibilities, not promises.

Explanations are predictions from text. We have not verified whether a reduction is present in the audio. Style changes the analysis and playback speed, not reliably the pronunciation.

03
Explore at your own pace.

Word timings are estimated. IPA is a dictionary-based word form, not a transcription of the generated voice. Save phrases locally in your browser.

Text is sent to Cloudflare Workers AI when speech is requested. This app does not persist audio on its server; saved phrases stay in this browser. No microphone is required.
