DeepL, a global leader in Language AI, has announced the integration of the team and technology from Mixhalo, a San Francisco-based audio streaming platform. This strategic move is set to enhance DeepL's real-time voice translation capabilities for large-scale applications like global conferences and enterprise workflows. The acquisition also marks the establishment of DeepL's first office in San Francisco, reinforcing its expansion in the United States.


Enhancing Real-Time Translation with Ultra-Low Latency

Mixhalo is renowned for its ultra-low latency audio technology, capable of delivering high-fidelity sound to thousands of listeners simultaneously. The platform has been trusted by major names in sports, entertainment, and technology, including MLB, Metallica, and Salesforce for their flagship events. Its system ensures audio reaches audiences through their phones with virtually no perceptible delay, creating a seamless live experience.

The integration of Mixhalo's technology will significantly bolster DeepL Voice, which already leads the market in translation quality and speed. By combining DeepL's rapid AI translation with Mixhalo's near-instantaneous audio delivery, the company aims to create a truly fluent and natural communication experience. This synergy will allow translated speech and captions to reach large audiences without the typical lag associated with such services.

A Strategic Move for Market Expansion

This development signals a major push into the American market, DeepL's fastest-growing region, with the opening of a new San Francisco office. The company already serves a substantial US customer base, including prominent clients like NVIDIA and Cisco, with nearly half of Fortune 500 companies using its services. This physical presence in the heart of the tech industry will accelerate customer adoption and partnership opportunities.

The collaboration is a formalization of an already successful partnership, as Mixhalo previously utilized the DeepL Voice API to power its real-time translation offerings. This proven combination has already been deployed at major global conferences, demonstrating its effectiveness in real-world, high-stakes environments. By bringing the technology in-house, DeepL can now more deeply integrate and scale these powerful capabilities for its global clientele.

The Future of Voice AI Communication

According to CEO Jarek Kutylowski, the combined technologies will build a real-time Language AI layer for all forms of communication. The vision extends beyond conferences to include team meetings, customer support centers, and other enterprise workflows where language barriers exist. This move positions DeepL to become an integral part of the infrastructure for global business communication.

The speed advantage gained from Mixhalo's technology provides more than just faster delivery; it creates opportunities for qualitative improvements. This saved time allows DeepL's AI to layer on features like personalized voice cloning, nuanced intonation, and emotional accuracy. The result is a translated voice that more faithfully reproduces the original speaker's delivery and intent.


The integration of Mixhalo's team and technology represents a transformative step for DeepL in the competitive Voice AI landscape. By solving the complex challenge of delivering high-quality, low-latency audio at scale, the company is poised to set a new standard for real-time translation. This strategic enhancement solidifies DeepL's mission to break down language barriers and enable seamless, natural communication across the globe.
