Keybox Player AutoScript is an innovative repeat player app for learning a language.
Patent 10-2018-0005018 (Application N0.) With existing language repeater apps, you guess which part you want to replay, and clumsily move back-and-forth the proceeding bar. Keybox Player, on the other hand, splits the audio file and shows the corresponding script automatically. So you can pinpoint where you want to repeat. No guesswork, no error in section playing. Keybox Player let you repeat after audio sections and even scores how good your pronunciation is. Instead of passive listening mode, your language learning becomes more active and enhanced. Supports multiple languages (English, French, German, Chinese).
