Tips for better Korean TTS results:
- Use proper Korean punctuation to control pacing โ commas (,) create short pauses, periods (.) create stops, and question marks (?) naturally raise pitch
- Write in standard Hangul (ํ๊ธ) orthography for the most reliable pronunciation โ 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 โ 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 โ the model adjusts pitch and energy for emphatic Korean sentences
- For formal vs informal speech (์กด๋๋ง vs ๋ฐ๋ง), the model preserves the register you write in โ choose your speech level in the text

Offline behavior depends on the selected engine and language. Supertonic, Piper, Kitten, 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.
