Writing a Role Prompt That Acts Like a Great Tutor
Generic 'let's chat in French' sessions wander into long textbook paragraphs. Instead, start a custom session and write three specific rules in the instructions:
1) Pick a concrete scene—ordering hardware parts, a job interview intro, or checking into a hotel. 2) Ask the assistant to speak one or two sentences per turn at B1/B2 speed. 3) Tell it to answer naturally first and append a one-line phrasing tip only when your grammar obscures meaning. That keeps conversation flowing without turning every sentence into a grammar quiz.
Rehearsing Talks and Pronunciation with Karaoke Readback
When you have a specific paragraph, conference pitch, or set of idiomatic sentences you want to internalize, switch to Karaoke Readback.
Using Apple's on-device speech recognition, words light up in real time as you pronounce them clearly—instantly revealing which syllables or liaisons trip your cadence, without burning cloud audio credits.

Frequently Asked Questions
Does Karaoke Readback spend my monthly AI credits?
Karaoke word-highlighting uses Apple's on-device speech recognition engine, so rehearsing passages aloud does not stream continuous cloud audio.
Can I schedule daily 10-minute speaking drills?
Yes. Use the built-in Scheduler tab (under More on iPhone) with notification reminders to build a consistent ten-minute daily speaking habit.
