Voice AI has emerged as one of many hottest sectors in AI, with traders pouring in billions of {dollars} to serve use circumstances starting from automating buyer assist and gross sales calls to creating assembly notetakers and growing AI good glasses that use voice as the first interplay floor.
In the meantime, AI labs are rapidly releasing fashions, and {hardware} makers try to create the perfect expertise for shoppers to work together with gadgets.
All of this new know-how wants testing and a suggestions loop for enchancment. An Iceland-based startup, Treble, is positioning itself to be on the heart of the voice AI trade by making a simulation platform that may cater to mannequin makers, robotics corporations, and shopper {hardware} makers.
The corporate, based in 2020 by acoustic engineers Finnur Pind and Jesper Pedersen, has raised $18 million in an extension of its Collection A funding led by Paladin Capital Group, with participation from current traders KOMPAS VC, Frumtak Ventures, EIC, and Omega ehf. It obtained an funding of $12 million in 2024, bringing its whole elevate thus far to over $40 million. The startup counts Amazon and Logitech as clients.
Treble has a couple of verticals associated to simulation and information. For voice AI corporations, it has an artificial information era platform that might be used for speech enhancement, noise suppression, and mannequin coaching. It additionally evaluates voice AI fashions in several circumstances to offer suggestions to labs. Earlier this yr, it partnered with Hugging Face to launch a benchmark for speech recognition fashions across different realistic conditions.
“Audio AI is mostly a information problem, and that is the place essentially the most alternatives to allow next-generation fashions and {hardware} lie. Thus far, just about all sound-related AI has been made out of recordings and information scraped from the web. We consider that correct physics simulation may be an alternate method to create information for sound,” Pind informed TechCrunch.
The startup additionally focuses on {hardware} design and testing from a voice perspective. As an example, it really works with headphone and speaker corporations for digital prototyping to assist them perceive how their product would possibly sound. It may additionally take a look at how a sensible speaker can perceive instructions primarily based on the positioning of the speaker. Currently, Treble has ventured into offering simulation testing for good glasses and AI gadgets.
Pind mentioned that the corporate is worked up to work on wearables that would improve listening to for customers.
“I’m actually excited in regards to the subsequent era of those gadgets like headphones and good glasses that may allow [a feature like] superhuman listening to. That’s an space the place you may actually simply hear higher in difficult acoustic environments. Possibly you might be in a restaurant, and also you solely wish to hear folks inside two meters of vary, or you might be in a seminar, and wish to mute folks round you,” he mentioned.
Treble goals to extend its focus within the bodily AI house, together with robotics, automotive, and drone corporations, to allow sound-based features for them via testing and simulation.
Francois Ruether, VP of Paladin Capital Group, informed TechCrunch that Treble’s platform, which simulates totally different fashions and gadgets, stands out; the platform’s significance will enhance because it will get concerned in additional areas.
“Our thesis is that, as extra merchandise depend upon understanding sound, this infrastructure turns into more and more useful throughout voice AI, wearables, robotics, and bodily AI. Clients retain possession of their fashions, merchandise, and improvement workflows, whereas benefiting from a shared basis of a simulation-native acoustic infrastructure layer,” Ruether mentioned.
