Voice AI has emerged as one of the hottest sectors in AI, with investors pouring in billions of dollars to serve use cases ranging from automating customer support and sales calls to creating meeting notetakers and developing AI smart glasses that use voice as the primary interaction surface.
Meanwhile, AI labs are quickly releasing models, and hardware makers are trying to create the best experience for consumers to interact with devices.
All of this new technology needs testing and a feedback loop for improvement. An Iceland-based startup, Treble, is positioning itself to be at the center of the voice AI industry by creating a simulation platform that can cater to model makers, robotics companies, and consumer hardware makers.
The company, founded in 2020 by acoustic engineers Finnur Pind and Jesper Pedersen, has raised $18 million in an extension of its Series A funding led by Paladin Capital Group, with participation from existing investors KOMPAS VC, Frumtak Ventures, EIC, and Omega ehf. It received an investment of $12 million in 2024, bringing its total raise to date to over $40 million. The startup counts Amazon and Logitech as customers.

Treble has a few verticals related to simulation and data. For voice AI companies, it has a synthetic data generation platform that could be used for speech enhancement, noise suppression, and model training. It also evaluates voice AI models in different conditions to provide feedback to labs. Earlier this year, it partnered with Hugging Face to launch a benchmark for speech recognition models across different realistic conditions.
“Audio AI is really a data challenge, and this is where the most opportunities to enable next-generation models and hardware lie. To date, pretty much all sound-related AI has been made from recordings and data scraped from the internet. We believe that accurate physics simulation can be an alternative way to create data for sound,” Pind told TechCrunch.
The startup also focuses on hardware design and testing from a voice perspective. For instance, it works with headphone and speaker companies for virtual prototyping to help them understand how their product might sound. It could also test how a smart speaker can understand commands based on the positioning of the speaker. Lately, Treble has ventured into providing simulation testing for smart glasses and AI devices.
Pind said that the company is excited to work on wearables that could enhance hearing for users.
“I’m really excited about the next generation of these devices like headphones and smart glasses that can enable [a feature like] superhuman hearing. That’s an area where you can really just hear better in challenging acoustic environments. Maybe you are in a restaurant, and you only want to hear people within two meters of range, or you are in a seminar, and want to mute people around you,” he said.
Treble aims to increase its focus in the physical AI space, including robotics, automotive, and drone companies, to enable sound-based functions for them through testing and simulation.
Francois Ruether, VP of Paladin Capital Group, told TechCrunch that Treble’s platform, which simulates different models and devices, stands out; the platform’s importance will increase as it gets involved in more areas.
“Our thesis is that, as more products depend on understanding sound, this infrastructure becomes increasingly valuable across voice AI, wearables, robotics, and physical AI. Customers retain ownership of their models, products, and development workflows, while benefiting from a shared foundation of a simulation-native acoustic infrastructure layer,” Ruether said.

The Nigeria Police Force has confirmed the arrest of a 22-year-old man, Umar Ibrahim Gandi Maradun, over a viral video allegedly showing him calling for the use of AK-47 rifles to kill Christians in Enugu and Plateau states.
Politics Nigeria reports that the suspect, a native of Maradun Local Government Area of Zamfara State, was arrested for investigation after the video circulated on social media and sparked concerns over religiously motivated violence.
In a statement issued on Tuesday, October 27, 2026, the Force Public Relations Officer, Chief Superintendent of Police (CSP) Ani Iniedu, said the Zamfara State Police Command had activated its intelligence resources to identify those involved in the incident.
The police also confirmed that the command had engaged the leadership of Jama’atu Izalatil Bidi’a Wa’ikamatus Sunnah (JIBWIS) at the national and state levels following the emergence of the video.
According to the police, the organisation disassociated itself from the alleged conduct and handed the suspect over to the authorities for investigation.
The video reportedly showed the suspect wearing JIBWIS uniform and appearing alongside pupils from two Islamic schools in Maradun: Nurul Islam Islamiya and Akidatul Sahiha Islamiya.
Preliminary findings by the Zamfara State Police Command indicated that the video was recorded on Friday, October 23, 2026, while the suspect was reportedly on his way to Aliyu Ibn Abi Thalib Mosque, where he and others allegedly provided security during Friday prayers and preaching.
The suspect was born on September 15, 2004. He reportedly attended Mualledi Model Primary School and Government Day Secondary School, both in Maradun.
He also reportedly joined JIBWIS in 2025 and recently gained admission to study Mass Communication at Zamfara State University, Talata Mafara.
The police said a comprehensive investigation had commenced and that the suspect would be charged before a competent court if sufficient evidence established an offence under applicable law.
Earlier, the Zamfara State Commissioner of Police, Bello, said the investigation would consider allegations of incitement to violence, disturbance of public peace and criminal intimidation under Sections 77, 78 and 380(b) of the Penal Code Law applicable in the state, subject to the evidence gathered and applicable law.
The police also condemned statements capable of promoting religious hatred, threatening community safety or undermining peaceful coexistence.
“The Zamfara State Police Command remains resolute in its duty to uphold the law, protect lives and property, defend the rights of all citizens without discrimination, and work with relevant stakeholders to sustain peace and security throughout Zamfara State,” the commissioner said.
The development comes as JIBWIS has publicly distanced itself from the video and condemned calls for violence against non-Muslims.
The group’s National Publicity Secretary, Sheikh Ahmad Muhammad Ashiru, stated this in a statement issued at its headquarters in Jos on Tuesday.
Ashiru said the organisation had yet to establish the authenticity of the video but maintained that its position against violence was clear.
“We are yet to confirm whether the video is authentic, but our position against violence remains clear,” he said.
He added that JIBWIS, under the leadership of Ash-Sheikh Muhammad Sani Yahaya Jingir, would not support calls to attack or kill anyone because of their religious affiliation.
Ashiru said banditry, kidnapping, armed robbery and Boko Haram attacks were already affecting communities across the country, warning that statements promoting violence could heighten tensions and threaten peaceful coexistence.
“We would not support any call capable of disturbing the peace of Nigeria, as such comments are capable of inciting violence and creating unnecessary tension among Nigerians,” he said.

The JIBWIS spokesperson stressed that anyone making such statements in the organisation’s name did not represent its position.
He urged security agencies to investigate the video, establish its authenticity and identify those responsible, adding that anyone found culpable should face the law after a proper investigation.
Meanwhile, the Nigeria Police Force has urged members of the public to remain calm, avoid circulating unverified information and refrain from sharing the video in ways that could escalate religious tensions.
The Force reiterated its commitment to protecting Nigerians irrespective of religious affiliation and taking lawful action against conduct capable of inciting hatred or threatening public peace.
Senator Victor Umeh has accused Anambra State Governor Chukwuma Soludo of acting out of envy and hatred towards presidential candidate of the Nigeria Democratic Congress, NDC, Mr Peter Obi.
Umeh claimed that Soludo was trying to surpass Obi's political record, insisting that the former Anambra governor remained more popular than his successor in the state and across Nigeria.
The senator made the remarks on Tuesday while fielding questions on Channels Television's Politics Today programme.
Umeh, who said he attended the University of Nigeria, Nsukka, UNN, alongside Obi and Soludo between 1980 and 1984, suggested that their shared academic background might have contributed to what he described as peer envy.
He said, “He (Peter Obi) cannot be drawn to what is called the peer envy and hate. You know, all of us were in the university together. Myself, Soludo, Peter Obi. We were at the University of Nigeria from 1980 to 1984, all of us graduated the same day.
“So sometimes when you see people talk, they talk out of maybe peer envy. He (Soludo) is running after Peter Obi's record.”
The senator further argued that Obi remained more popular than Soludo despite the latter's position as governor of Anambra State.
“Whether he likes it or not, today, no matter what Soludo does, Peter Obi will continue to be more popular than him, both in Nigeria and in Anambra State. Go there and see,” Umeh added.
Obi served as governor of Anambra State from 2006 to 2014. Soludo became governor in 2022.
