PlayAI secures $21m to bring real-time agents and voice interfaces to businesses, developers and creators

PlayAI, the voice AI platform powering the future of conversational AI, has raised $21 million seed round led by Kindred Ventures and 500 Global with participation from Race Capital, Y Combinator, Soma Capital, Pioneer Fund, TRAC, and others. As part of the announcement, Steve Jang of Kindred Ventures joined as a board observer. The company will use the capital to invest in its generative AI voice models, voice agent platform, and to shorten the time for businesses to build human-quality speech experiences.

PlayAI has also released a new version of its speech model, PlayDialog, a multi-turn Text-to-Speech model that uses a conversation’s historical context to control prosody, intonation, emotion and pacing to deliver more natural sounding speech. Trained on hundreds of millions of conversations that represent real-world examples, PlayDialog delivers human-like conversation with natural delivery and appropriate tone in real time. 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 captivating stories, podcasts, briefings, and more in just minutes.

''Speech as an interface is exploding in popularity, and we knew it was a massive opportunity from the get-go," said Mahmoud Felfel, Co-founder and 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. This funding will help us deliver our vision of powerful, emotive, and human-like voice interfaces for any application."

The AI-powered voice generation industry is expected to grow more than fourfold over the next decade, according to a new Market.Us report. Both enterprise and consumer applications are rapidly adopting generative AI delivered speech capabilities to provide human-like conversational experiences that far surpass previous generations of voice technology. Previous generations of voice technology sounded unnatural because they lacked prosody – correct latency, pacing, emphasis and cadence of speech – the very qualities that make speech sound human and familiar.

PlayAI enables developers to create their own powerful voice applications without having to build their own model. The company uses custom large language models (LLMs) trained on an extensive dataset of diverse human speech, representing speech styles like podcasts, narrations, storytelling and business conversations with state-of-the-art voice cloning across multiple languages and accents. These powerful, low-latency models are accessible to every developer of enterprise and consumer applications through text-to-speech APIs.

In addition to its new PlayDialog model, PlayAI also offers Play 3.0 mini, a lighter weight low-latency model that supports 30+ languages and a voice agent platform that allows the rapid creation of generative AI voice agents for applications as diverse as 24/7 customer support, appointment scheduling and sales lead engagement. Play 3.0 mini serves industries including healthcare, travel, hospitality and retail, and seamlessly integrates with many of today’s most popular business applications with simple set-up within 20 minutes.

''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.''
