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 African Democratic Congress Presidential Campaign Council (ADC-PCC) has said poor welfare, inadequate salaries and rising living costs are making it difficult for Nigerian teachers to perform their duties effectively.

The council said teachers, who play a major role in educating children and shaping the country’s future, are facing worsening working and living conditions.

The ADC-PCC Director of Media and Publicity, Kola Ologbondiyan, stated this in a message marking the 2026 World Teachers’ Day.

Ologbondiyan described teachers as the backbone of national development, saying many had continued to work despite what he described as years of neglect and hardship.

“Nigerian teachers are true heroes. They have continued to mould lives, build character and sustain our educational system even in the face of neglect and hardship,” he said.

“We are seeing teachers struggle with rising living costs, irregular and inadequate salaries, poor welfare, limited opportunities for training and deteriorating school infrastructure,” he said.

Ologbondiyan also linked the difficulties to the removal of the petroleum subsidy, saying teachers had not received adequate support to cope with the resulting increase in the cost of living.

He questioned how teachers could perform effectively when they struggled to meet basic needs such as transportation, healthcare and accommodation.

“How can a teacher teach effectively on an empty stomach?” he asked.

He added that high transport costs, inadequate salaries, limited access to medical insurance and the high cost of decent accommodation were placing additional pressure on teachers.

The ADC Presidential Campaign Council also alleged that the teaching profession had been devalued under the All Progressives Congress-led administration.

It cited what it described as poor remuneration for primary and secondary school teachers and repeated industrial actions by tertiary education workers over welfare and working conditions.

Ologbondiyan said teachers had continued to perform their duties and deserved improved working conditions and professional support.

He said an ADC administration led by its presidential candidate, Alhaji Atiku Abubakar, would make education and teachers’ welfare a priority if elected in 2027.

According to him, the proposed measures would include better wages and allowances, health insurance, affordable housing, professional development and improved teaching and learning facilities.

The National Peace Committee, spearheaded by former Head of State, General Abdulsalami Abubakar (rtd.), has warned President Bola Tinubu, former Vice-President Atiku Abubakar, Peter Obi and other political actors against inflammatory and inciting campaigns ahead of the 2027 general elections.

The committee issued the warning in a statement jointly signed by Abubakar and Bishop Matthew Hassan Kukah on Monday.

It also raised the alarm over 60 election-related incidents recorded across the country within one month, including political violence, intimidation, threats, attacks on political activities and misinformation.

The statement partly read:

“To political parties, candidates, and supporters: Immediately stop false, inflammatory or inciting communication. Uphold the commitments of the Accord, verify information before publication, and actively prevent supporters from engaging in unlawful conduct, intimidation, or disruption.

“As the 2027 electoral cycle progresses, the message of the NPC remains clear and unwavering. Every candidate must be able to campaign peacefully; every political party must be able to organise lawfully; and every citizen must be able to make a political choice without intimidation or coercion.

“To INEC, strengthen monitoring of political campaigns and ensure compliance with the Electoral Act 2026 and applicable regulations governing political parties and campaign conduct.

“Where breaches are identified, the commission should take appropriate regulatory action within its mandate and promptly refer suspected criminal violations to the relevant law-enforcement agencies.”
