Pinyin Input

When preset phrases and custom content are not sufficient to express an idea, users can navigate to the third quadrant (bottom-left) for "Pinyin Input".

Basic Operation

1. Progress through the four-quadrant tree to select the initial consonant (shengmu).
2. Once the initial is selected, the interface displays valid combining final vowels (yunmu).
3. Upon selecting the final, the complete Pinyin syllable is appended to the top phrase bar, returning to the home screen.

Multiple syllables can be entered consecutively. When AI is active, consecutive syllables at the end of a sentence are processed collectively (for instance, jue ding suggests "决定..." rather than analyzing ding in isolation). Selecting a Chinese AI suggestion replaces the typed Pinyin segment while retaining all prior phrases as contextual semantic input.

The top-left "Back" shortcut steps up one level in the Pinyin tree; on the root finals page it returns to initials selection, and on the root initials page it exits Pinyin input back to the home screen.

AI Pinyin Predictions

When AI is enabled, the two bottom quick prediction buttons provide direct Chinese phrase recommendations based on the active phonetic branch:

• During the initials stage, the leading character of suggested words matches the active initials group.
• During the finals stage, suggestions match the complete combinable syllables.
• Selecting a bottom Chinese prediction appends it directly to the sentence and returns home.

If AI is disabled or daily quota is depleted, bottom predictions will not appear, but standard quadrant navigation through initials and finals remains fully accessible.

NOTE

The fixed Pinyin navigation tree inserts phonetic syllables. To produce native Chinese characters directly, use the bottom AI candidates when AI is enabled.

Pinyin syllables remain displayed phonetically on screen. During speech synthesis (both auto-speak and full-sentence speech), the app maps syllables on-device to homophonic Chinese characters before passing text to the iOS speech synthesizer, preventing Apple's TTS engine from misinterpreting short syllables as English acronyms or musical terms.
