Compare recognized words
Review omitted, substituted, or extra words. Speech recognition can make mistakes, especially for accented or unusual words, so differences are cues to practice—not a diagnosis.

Tip: Start slowly, then try the whole sentence naturally.
Reference speech uses browser/OS voices. Some voices may use a provider's online service. The voice audio is not available for export.

Analyze your delivery
The optional AI model runs in your browser after downloading assets. It does not upload your recordings to PixelOkay.
Editing the transcript changes the text-match estimate. It cannot turn the result into a verified acoustic pronunciation score.
For on-device AI, first record or upload a short phrase.

SMART PRACTICE, HONEST FEEDBACK
Learn what the microphone can—and can't—tell you.
Understand your pacing
Inspect the waveform, estimated speaking time, longer energy gaps, and relative recording level. Quiet speech and background noise can affect these measurements.
Explore selected IPA sounds
Reference IPA notes help with English consonant contrasts. Accurate assessment of individual spoken phonemes would require a separate calibrated phoneme-recognition model.
Frequently asked questions
Is this a phoneme-level pronunciation examiner?
No. The current coach can compare recognized words and provide IPA reference guidance for selected phrases. It does not claim to identify actual mispronounced phonemes or measure accent quality. A calibrated acoustic pronunciation model would be required for that.
Does it work fully in the browser?
The editor, recording, playback, acoustic level estimates, and manual text comparison work without a backend. Optional local AI transcription downloads model/runtime assets only after you choose Download & Load Model in Model Setup. Analyze then uses the initialized model. Browser dictation may send audio to a speech-service provider; choose it only if that is acceptable.
Does using the AI model require payment?
No paid API or account is required. The first use needs a potentially large model download and a device capable of running it. Subsequent use may be cached. Some low-memory devices may not support inference.
Why doesn't transcript agreement prove correct pronunciation?
Speech recognition is designed to recover words, not score each speech sound. It can recognize a word despite non-standard pronunciation, or misrecognize a correctly spoken word. Treat its results as practice guidance only.
Can I practice privately?
Recording and local analysis do not upload audio to PixelOkay. The optional local model fetches code and model assets from third-party hosts. Reference voices and the separate browser dictation option may use operating-system or browser online services.
Does it support languages other than English?
This release targets English phrases and an English-language Whisper model. Reference voices depend on your device; a full multilingual assessment and phoneme dictionaries are future work.
