01

Start a session

Choose your JLPT level and available unit, review the session summary, then press Start. The app cues you before it listens.

02

Microphone permissions

Live spoken answers require Microphone access. Japanese hands-free commands also require Speech Recognition access.

03

On-device speech matching

CTC means Connectionist Temporal Classification. Kanji Aloud uses it with a bundled neural network to compare the captured speech sound with the expected Japanese reading directly on the iPhone.

04

iCloud progress

Study always starts from local data. When iCloud is available, private CloudKit sync can restore and merge progress without a Kanji Aloud account.

05

Achievements

The Board works locally. Signing into Apple Game Center adds Apple-managed achievements and friend leaderboards when available.

06

Hands-free safety

Use voice control only when your surroundings and activity make it safe. Stop the session whenever the display or audio becomes distracting.
