# Khmer text-to-speech — ការបម្លែងអត្ថបទជាសំឡេងខ្មែរ

Type Khmer text, hear natural Khmer speech. Free demo, two voices (male/female).

វាយអត្ថបទខ្មែរ ហើយស្តាប់សំឡេងអានដោយ AI — ឥតគិតថ្លៃ។ អាចអានលេខ កាលបរិច្ឆេទ
និងអត្ថបទវែងៗបានដោយស្វ័យប្រវត្តិ។

**How it works:** an F5-TTS model fine-tuned on ~1,000 hours of Khmer speech,
with a purpose-built Khmer text front-end — automatic number verbalization
(២៥ → ម្ភៃប្រាំ), sentence-aware chunking for paragraphs, and Khmer Unicode
repair. In our held-out evaluation it transcribes more intelligibly (ASR CER)
than Google Translate's Khmer voice and Meta MMS.
