CoeFont Interpreter Evolves to Correctly Understand 'Japanese-Accented English'

CoeFont Inc. (Headquarters: Minato-ku, Tokyo; CEO: Shogo Hayakawa) is pleased to announce that its AI interpretation service, "CoeFont Interpreter," has implemented speech recognition tuning optimized for Japanese-accented English (characteristics specific to Japanese speakers, such as intonation, rhythm, and pronunciation tendencies).

This update resolves a long-standing bottleneck where traditional AI speech recognition would fail to correctly identify or translate English spoken with typical Japanese pronunciations.

Background: The Biggest Hurdle in AI Interpretation - "Japanese-Accented English is Not Recognized"

Opportunities for Japanese people to speak English in business settings—including inbound tourism, overseas business trips, and international conferences—are rapidly increasing. However, many conventional AI interpretation and speech recognition engines are built based on native speaker utterances. This has created a critical challenge where recognition accuracy significantly drops for characteristics common to Japanese speakers, such as flat intonation, rhythm segmented by syllables, and "Katakana English" pronunciation.

As a result, many users have faced the frustration of AI failing to accurately pick up their words, causing the translation function to malfunction.

To address these practical challenges faced by business professionals and to eliminate the psychological burden of needing to sound native, the company has worked on strengthening speech recognition specifically for the speaking patterns of Japanese speakers.

New Feature Overview: Connect with the World in Your Own Way

"CoeFont Interpreter" has comprehensively learned the characteristic speaking patterns found in Japanese English (such as limited intonation, unique pauses, and word-ending processing). By tuning the speech recognition engine's algorithm, the recognition rate for "Japanese English" has been significantly improved.

This enables speakers, even those lacking confidence in their pronunciation or intonation, to utilize "CoeFont Interpreter" for high-level communication naturally without forcing themselves to correct their own speaking style.

Potential Use Cases

- Inbound Hospitality (Tourism, Food & Beverage, Accommodation): Staff who are less confident in their language skills can convey their hospitality to overseas visitors using their own natural English, without worrying about using unnatural pronunciation to please the AI.
- Overseas Business Trips & International Conferences: Freed from the stress of thinking, "The AI will ignore me if I don't pronounce it as beautifully as a native speaker," users can focus on the essence and content of the discussion.
- Internal English Meetings: In global corporate meetings, the service supports an environment where statements made by non-native Japanese employees are accurately and clearly conveyed to international colleagues through AI.
