LTP Growth, Voice AI Valuations, RWS, Appen, Lionbridge

Slator’s Head of Research Anna Wyndham joins Florian on the pod to discuss Slator’s new Pro Guide: Growth Hacks for Language Technology Platforms, describing it as a practical playbook for turning strong AI products into scalable revenue.

Florian highlights ElevenLabs’ USD 500m raise at an USD 11bn valuation and Synthesia’s USD 200m round as evidence that investor appetite for voice AI is accelerating rapidly. 

Florian connects that funding momentum to product launches, including ElevenLab’s Expressive Mode and YouTube’s expanding AI dubbing push.

The duo then reviews YouTube’s AI dubbing in German and Spanish, finding the intelligibility and naturalness impressive, but rhythm and intonation still mirroring the English source language too closely.

Anna turns to new academic research arguing that current text-to-speech evaluation methods under-test real-world deployment factors such as long-form consistency, punctuation handling, and robustness across messy inputs.

Anna reports that Appen delivered double-digit revenue growth and an EBITDA turnaround in Q4 FY25, driven by a higher share of generative AI projects and strong momentum in China.

Florian closes by touching on prompt injection issues in AI translation tools, RWS’s return to growth, and Lionbridge’s ownership transition.
