Japanese Proper-Noun Fine-tuned Qwen3-ASR

A fine-tuned checkpoint of Qwen/Qwen3-ASR-1.7B optimized for Japanese automatic speech recognition.

This variant is specifically trained to improve recognition of Japanese proper nouns, organization names, product names, service names, and kanji-heavy expressions that general-purpose ASR models tend to mistranscribe.

Intended Use

Designed for Japanese ASR tasks requiring accurate transcription of:

• Proper nouns (people, places, organizations)
• Difficult or uncommon kanji spellings
• Company and product names
• Mixed Japanese/English technical terminology

Example Normalizations

Product / Company Names

Japanese Numerals

Math / Code
