Browser audio synthesis; text handling and network needs depend on the selected engine and language.
Generate natural Korean speech directly in your browser with Supertonic 3. The model downloads once, and all processing β text normalization, phonemization, and audio synthesis β runs locally on your device.
Available voices: Supertonic 3 offers 10 built-in voices (M1-M5, F1-F5) that work with Korean text input.
Tips for better Korean TTS results:
- Use proper Korean punctuation to control pacing β commas (,) create short pauses, periods (.) create stops, and question marks (?) naturally raise pitch
- Write in standard Hangul (νκΈ) orthography for the most reliable pronunciation β the model handles Korean's phonetic writing system naturally
- For mixed Korean-English text, keep Korean portions in Hangul and English portions in Roman characters β the model handles code-switching well with Supertonic 3
- Break long paragraphs into shorter sentences for clearer enunciation and more natural delivery
- Use exclamation marks for emphasis β the model adjusts pitch and energy for emphatic Korean sentences
- For formal vs informal speech (μ‘΄λλ§ vs λ°λ§), the model preserves the register you write in β choose your speech level in the text

Korean Uses the Supertonic Local Processing Route
Korean on OfflineTTS uses Supertonic rather than the Kokoro server-phonemization path. After the required model and style assets have loaded, Korean text normalization, phonemization, and waveform synthesis run in the browser. The first visit and uncached model fetch still need network access, and clearing site data removes those cached assets.
The ten M1βM5 and F1βF5 labels identify preset styles; they do not certify age, identity, dialect, or professional suitability. Compare voices with the same Korean passage and speed. Use standard Hangul, preserve spacing and punctuation, and ask a fluent reviewer to check any narration intended for lessons, customers, or public distribution.
Check Korean Spacing, Number Systems, and English Brand Names
Build a test passage with personal and place names, counters, dates, telephone numbers, prices, Sino-Korean and native Korean numerals, honorific forms, and English product names. Write a value as words when only one reading is acceptable. Mixed Korean-English content can vary by term, so test every important code-switched phrase instead of relying on a generic demo.
Generate coherent sections and listen through automatic joins for repeated syllables, clipped endings, or unnatural pauses. Keep the approved Hangul source, engine version, voice style, speed, browser, and export date with the WAV or MP3. Local synthesis does not remove the need to confirm script rights, avoid impersonation, and secure downloaded audio containing sensitive information.

Korean Text to Speech β FAQ
Is Korean text to speech free?
Yes. OfflineTTS does not charge per character and requires no signup or API key. Audio synthesis runs in your browser with the engine you select.
Does Korean text to speech work offline?
Offline behavior depends on the selected engine and language. Supertonic, Piper, Kitten, Pocket TTS, and English Kokoro can synthesize locally after their model files download. Non-English Kokoro uses the OfflineTTS phonemization service before audio is generated on your device.
Is my Korean text data private?
Audio synthesis runs locally in your browser. Fully local-capable engine and language combinations keep the input on your device after model download. Non-English Kokoro sends plain text to the OfflineTTS phonemization service and receives pronunciation data before local synthesis.
