From March 3–6, Whispp is back at Mobile World Congress (MWC) Barcelona 2025, hosted by GSMA, showcasing the latest updates to our on-device voice AI technology. After being a finalist at 4YFN 2024, we’re thrilled to return with even more powerful solutions that make speech accessible for everyone.
Whispp enables people with impaired or lost speech to communicate clearly by converting whispered or affected speech into a natural, intelligible voice—in real-time.
This year, we’re introducing Live Conversations:
Our lowest-latency, on-device voice AI, designed to work even in noisy environments. It enables people who’ve lost their voice to have live, in-person conversations—without delay or external devices.
But that’s not all. Our technology is expanding beyond traditional assistive use cases. Business users can now discreetly whisper during private phone or video calls, while maintaining vocal consistency and natural expression—even in high-demand conversations.
At 4YFN, we were honored to take the stage and share our vision for voice accessibility. One of the week’s major highlights? A visit from the Deutsche Telekom board, including Group CEO Tim Höttges and Claudia Nemat, who experienced Whispp firsthand. Their enthusiasm for inclusive communication solutions echoes a broader industry trend: tech that empowers every voice.
We also welcomed Dirk Beljaarts from the Dutch Ministry of Economic Affairs, reinforcing the Netherlands’ support for breakthrough innovation in AI and accessibility.
