DeepL Launches Voice-Preserving Real-Time Translation
On September 15, 2026, DeepL announced the general availability of a new feature for its "DeepL Voice" service that allows real-time voice translation while preserving the speaker's unique voice characteristics, tone, and tempo. The update supports 14 languages, including Japanese, and is available via desktop apps for Windows and Mac, integrating with Zoom, Microsoft Teams, and Google Meet. This technology moves beyond standard text-to-speech synthesis by cloning the speaker's vocal identity in the target language, aiming to reduce the "robotic" feel of previous AI interpreters and enhance emotional nuance in cross-language meetings.
Korean AI Firm Hudson AI Deploys at International Broadcast Event
Korean AI voice technology company Hudson AI provided real-time simultaneous interpretation services in six languages at the "2026 International Broadcast Content Market" (BCWW) held in Seoul from September 14–16. The event featured 403 companies from 17 countries, and Hudson AI's solution demonstrated low-latency translation capabilities suitable for high-stakes business environments. This deployment highlights the growing adoption of specialized Korean AI translation models in global industry events, competing directly with major players like DeepL and Google.
Smartling Report Confirms DeepL’s Expansion to 100+ Languages
A recent comparison by Smartling notes that as of September 2026, DeepL has expanded its translation support to over 100 languages, significantly closing the gap with Google Translate’s 130+ language pairs. While Google maintains broader coverage, DeepL continues to dominate in accuracy tests for European language pairs and has recently integrated more robust API pricing structures to attract enterprise clients. This expansion positions DeepL as a more viable alternative for multinational corporations requiring nuanced translation beyond just English-centric pairs.

Local view
In Japan, media outlets such as CNET Japan and AppBank have focused heavily on the "voice cloning" aspect of DeepL’s new release, emphasizing its utility for remote work platforms like Zoom and Teams. Nikkei reported on the feature's ability to maintain the speaker's "personality" through vocal characteristics, framing it as a breakthrough for natural-sounding business communication.
In South Korea, Edaily covered the competitive landscape by highlighting domestic success stories like Hudson AI’s deployment at BCWW 2026, suggesting a growing confidence in local AI interpretation solutions. Additionally, Good Morning Vietnam Media (reporting on Korean tech) detailed DeepL’s new desktop app for multi-language meetings, noting the support for voice-to-voice translation in over 30 languages, which aligns with the global launch but is being scrutinized for its latency and accuracy in Asian language pairs.
Context & numbers
- Duolingo User Base: As of Q1 2026, Duolingo reported 137.8 million monthly active users and 56.5 million daily active users, with revenue reaching $292.0 million (up 27% YoY).
