The demand for voice and speech recognition technologies is massive — and growing. An analysis by market research firm Markets and Markets found that the sector could be worth over $28.1 billion by 2027.
There’s no shortage of vendors providing voice and speech recognition solutions, but some newer upstarts have managed to carve out niches. Sanas is a good example. Founded in 2020, the company develops software that uses AI to adjust a speaker’s accent in real-time.
“At Sanas, we believe that while technology is transforming the industry, it shouldn’t replace human connection, but rather, enhance it,” Sharath Keshava Narayana, Sanas’ co-founder and president, told TechCrunch. “With the number of customer interactions continuing to scale globally, the need for human-to-human communication remains critical.”
Maxim Serebryakov launched Sanas with Shawn Zhang and Andrés Soderi while in college. The trio was inspired by a fellow student’s frustrating experience working in a call center.
“Max and Shawn’s friend, Raul, who had to return to Nicaragua to support his family, faced accent discrimination at his call center job,” Narayana said. “His experience with ‘accent neutralization training’ and the toll it took on him inspired Max and Shawn to build a solution to reduce accent bias.”
In 2021, Narayana, who previously co-founded call center startup Observe.ai, joined Sanas, and the company secured its first tranche of funding.
Sanas’ technology analyzes speech and outputs converted speech that matches a specified accent. The company claims it is able to preserve the original speaker’s emotion and “identity” while minimizing reverb, echo, and noise.
“What sets Sanas apart is the company’s patented AI technologies, which recognize phonetic patterns and adjust them instantly while keeping the speaker’s unique identity intact,” Narayana said. “Sanas’s AI models are trained with over 50 million utterances of speech using datasets collected from our technology partners and in-house voice actors.”
Recently, Sanas acquired InTone, a competitor, which Narayana said “strengthens Sanas’ IP portfolio” and positions the startup to serve a wider customer base.
Today, Sanas has around 50 customers in industries including healthcare, logistics, and hardware manufacturing. Narayana said that the company’s annual recurring revenue has reached $21 million, up $3 million from last year.
Sanas is in a bit of a controversial business. Some research suggests that exposure to different accents in fact helps to combat bias. As technologists told The Guardian in a 2022 profile of the startup, Sanas’ solutions run the risk of homogenizing workers across call centers.
Narayana pushed back against this notion.
“What makes Sanas special is not just the technology, but its deeply human mission to break barriers, reduce discrimination, and amplify voices across the globe,” he said. “Together with my co-founders, we’re building a world where communication is a bridge — not a barrier.”
The mixed optics don’t appear to have impacted Sanas’ ability to raise cash. This week, Sanas announced that it closed a $65 million funding round that values the company at over $500 million. Quadrille Capital and Teleperformance led the round, which also had participation from Insight Partners, Quiet Capital, Alorica, and DN Capital.
Having raised over $100 million in capital to date, Sanas plans to build new “speech-to-speech” algorithms, expand to new regions, and “explore opportunities across industries such as healthcare, retail, and
beyond,” Narayana said.
“With a clear focus on scaling responsibly and innovating continuously, Sanas is well-prepared to weather potential headwinds,” he continued.
Sanas also intends to grow its roughly-150-person team, Narayana added, and open a new office in the Philippines, a country home to millions of contact centers.
