The company’s latest model uses a conversation’s historical context to facilitate natural, human-like conversational experiences.
With the AI-powered voice generation industry projected to grow fourfold in the coming decade (Market.Us report), investors are backing PlayAI. The two-year-old startup having served approximately 40,000 customers announced the closing of a $21 million Seed funding round to support its AI speech models and an AI voice agent platform.
PlayAI co-founders Hammad Syed and Mahmoud Felfel leveraged their experience as software engineers at UAE-based dubizzle, a classifieds website to buy, sell, and find anything. They seized an opportunity they observed in the rapidly growing AI arena, launching PlayAI with their shared vision to “Enable Delightful Human-AI Interactions”.
“Speech as an interface is exploding in popularity, and we knew it was a massive opportunity from the get-go,” said Felfel, CEO of PlayAI. “Building voice agents that can converse like humans and autonomously handle complex tasks is no easy feat, and I’m immensely proud of what our team has achieved.”
Instead of developers and businesses each building their own models, they use the PlayAI platform that enables them to build and deploy powerful voice applications—enhancing the work and performance of customer support teams, sales departments, content creators, and other growing industries.
As a result of this tech breakthrough, rapidly adopted generative AI-delivered speech capabilities that provide human-like conversational experiences are now surpassing previous generations of voice technology. PlayAI’s technology addresses the challenge of unnatural sound that lacks prosody – correct latency, pacing, emphasis and cadence of speech.
PlayAI accomplishes these significant improvements by using custom large language models (LLMs) trained on an extensive dataset of diverse human speech. The resulting speech styles are used in podcasts, narrations, storytelling, and business conversation, of which the latter entails state-of-the-art voice cloning across multiple languages and accents.
Now the low-latency models are readily available through text-to-speech APIs.
“PlayAI’s text-to-speech models have been incredibly valuable to our Agentic Phone Rep,” said Keith Fearon, Head of Growth at 11x, customer of PlayAI. “PlayAI’s models bring more natural, fluid sounding voices in multiple languages, and are delivered with ultra-low latency. Their on-prem offering makes it a natural fit for our application, where data security is crucial.”
PlayAI provides a growing range of capabilities. Users can create speech with PlayDialog through its editor, API, or via PlayNote, a just-launched tool that transforms PDFs, text, videos and other media into stories, podcasts, briefings, and more in just minutes. Its Play 3.0 mini is a lighter weight low-latency model that supports 30+ languages and a voice agent platform for a diversity of applications.
Kindred Ventures and 500 Global led the Seed round with participation from Race Capital, Y Combinator, Soma Capital, Pioneer Fund, TRAC, and others. The company will use the capital to invest in its generative AI voice models, and voice agent platform, while shortening the time for businesses to build human-quality speech experiences.
“We’ve been early big believers in the nascent and rapidly-evolving generative media space,” said Steve Jang, Founder and Managing Partner at Kindred Ventures. “AI voice generation platforms are fundamentally transforming how enterprise and consumer businesses are communicating with their customers, and we’re proud to back PlayAI to further the development of their powerful mission.”
