AI Dialect Preservation Engine DialectGuard Launches: Using AI to Record and Revive Endangered Languages

UNESCO and iFlytek jointly release AI dialect preservation engine DialectGuard, using AI speech synthesis and recognition to record and revive endangered dialects, completing digital preservation of 32 Chinese dialects.

UNESCO and iFlytek jointly released the AI dialect preservation engine DialectGuard on December 24. The system uses AI speech recognition and synthesis technology to digitally record, model, and restore endangered dialects, having completed digital preservation of 32 endangered dialects in China.

DialectGuard's workflow involves three steps: first, dialect speakers record 50 to 100 hours of voice data; then a dialect speech recognition model is trained; finally, fluent dialect speech can be synthesized from minimal new recordings. UNESCO's language diversity department head said approximately 3,000 languages worldwide face extinction risk, and DialectGuard provides a technological pathway for language preservation.
