I remember the first time I heard it. I was listening to a podcast, or so I thought. The host was interviewing a guest who had a very distinctive voice. Deep, resonant, with a slight accent I couldn't quite place. The conversation was fascinating, a deep dive into the future of AI. Then, at the end of the show, the host revealed that the guest was entirely generated by AI. The voice, the words, everything. I was floored. Not just because of the technology, but because of the emotional connection I had felt with a being that didn't even exist.
That was the moment I realized that AI voice was not just a novelty. It was a fundamental shift in how we interact with technology and with each other. And it’s a space I’ve been investing in heavily, with bets on companies like Anthropic, OpenAI, and a dozen other under-the-radar startups that are pushing the boundaries of what's possible. I'm not just talking about my angel investments; my first company, RemoteTeam, was acquired by Gusto, and we were already exploring how to use voice to make remote work more human. The potential is massive.
The Magic of AI Voice
Let's get one thing straight. This isn't about a slightly-less-robotic Siri or Alexa. We're talking about voices that are indistinguishable from humans. Voices that can convey emotion, nuance, and personality. The technology behind this is called text-to-speech, or TTS, and it has come a long, long way.
I remember playing with TTS in the early 2000s. It was a fun toy, but the voices were laughably bad. Tinny, robotic, and prone to mispronouncing even simple words. We've come a long way from that. Today, companies are using deep learning models like WaveNet and Tacotron to create voices that are not just realistic, but also controllable. You can specify the age, gender, accent, and even the emotional tone of the voice. It's like having a voice actor on demand, 24/7. I've seen startups in my portfolio that can generate a voice from a single sentence of text. It's insane.
And it's not just about creating new voices. It's also about cloning existing ones. With just a few minutes of audio, you can create a digital replica of someone's voice. This has huge implications for everything from personalized advertising to creating digital avatars of loved ones who have passed away. I’ve seen demos from some of my portfolio companies that would blow your mind. We’re talking about cloning a voice from a 30-second audio clip. It’s that good.
The Podcasting Revolution
One of the areas where I see the most immediate potential for AI voice is in podcasting. I'm a huge podcast listener, and I've even thought about starting my own. But the time commitment is huge. You have to record, edit, and produce each episode. It's a lot of work.
With AI voice, you can automate the entire process. You can write a script, choose a voice, and have a professional-sounding podcast in minutes. I'm not saying it will replace the top 1% of podcasters, but for the long tail of niche content, it's a game-changer. I'm advising a startup that's building a platform for this. They're not just creating a marketplace for AI voices; they're building a whole ecosystem around it, with tools for scriptwriting, editing, and distribution. You can even create multiple hosts with different personalities. Imagine a podcast where you can have a debate between a historian and a futurist, all generated by AI. The possibilities are endless.
I’ve seen startups that are building platforms for this. They are creating marketplaces for AI voices, where you can license the voice of a famous actor or a popular podcaster. It's a whole new economy being built around voice.
The Future of Conversational AI
Beyond podcasting, AI voice is going to change the way we interact with all of our devices. Voice assistants like Siri and Alexa are just the beginning. The next generation of assistants will be truly conversational. They will be able to understand context, remember past conversations, and even anticipate your needs.
I've invested in a few companies in this space, and the technology is incredible. We're talking about AI that can understand sarcasm, irony, and humor. AI that can have a real conversation with you, not just follow a script. One of my portfolio companies is working on a conversational AI for sales. It can handle initial customer inquiries, qualify leads, and even schedule meetings. It's like having a team of SDRs working 24/7. This is the holy grail of conversational AI, and we're getting closer to it every day.
Think about the implications. You could have an AI assistant that helps you with your work, your personal life, and your health. An assistant that you can talk to like a real person. It's like having a super-smart friend who is always there for you.
The Dark Side of AI Voice
Of course, with any powerful technology, there are also risks. The potential for misuse of AI voice is huge. We've already seen examples of deepfake audio being used to create fake news and propaganda. And the problem is only going to get worse as the technology gets better.
We need to have a serious conversation about the ethics of AI voice. We need to establish clear guidelines for how this technology can be used. And we need to develop tools to detect and flag deepfake audio. I’m not a fan of regulation, but this is one area where we might need it. I'm on the board of a company that's developing a watermarking technology for AI-generated content. It's a step in the right direction, but it's not a silver bullet. We need a multi-layered approach, with technology, regulation, and education.
I’m an optimist, but I’m also a realist. I know that there will be bad actors who will try to use this technology for malicious purposes. But I also believe that the good will outweigh the bad. The potential for AI voice to improve our lives is just too great to ignore.
My Prediction for the Future
So, what's my prediction for the future of AI voice? I believe that within the next 5 years, we will see AI voices that are so realistic that we won't be able to tell them apart from human voices. We will have AI assistants that are so smart that they will become our trusted companions. And we will have a whole new economy built around voice.
The Investment Landscape
As an investor, I'm constantly looking for the next big thing. And I believe that AI voice is one of the most exciting investment opportunities of the next decade. The market is still in its early days, but it's growing at an exponential rate. I'm not just talking about the big players like Google, Amazon, and Microsoft. I'm also seeing a ton of innovation from startups.
I'm particularly excited about companies that are building the infrastructure for the voice economy. This includes everything from TTS and ASR (Automatic Speech Recognition) engines to platforms for creating and distributing voice content. I'm also bullish on companies that are using AI voice to disrupt specific industries, like customer service, sales, and healthcare.
If you're an entrepreneur who's thinking about starting a company in the AI voice space, my advice is to focus on a specific niche. Don't try to build a general-purpose voice assistant. Instead, find a problem that can be solved with voice and build a solution for it. The opportunities are endless.
It's an exciting time to be an investor and an entrepreneur. The pace of innovation is faster than ever before. And I can't wait to see what the future holds. I’m putting my money where my mouth is, with over a dozen investments in the AI voice space. It’s going to be a wild ride.
Frequently Asked Questions
Do all experts agree with this view?
No, and that's fine. The best ideas in business are often contrarian. I share my perspective based on my experience and data, but I encourage you to seek out opposing viewpoints and form your own conclusions.
What experience informs this perspective?
This perspective comes from over a decade of building companies in Silicon Valley, two successful exits (RemoteTeam to Gusto, MovieLaLa to Gfycat), and investing in 200+ startups including Anthropic, OpenAI, and Scale AI. I write about what I've lived.
How can I apply this thinking to my own situation?
Start by identifying the core principle behind the opinion, not the specific example. Then ask yourself: does this principle apply to my context? If yes, test it in a small, low-risk way before going all in.
What's the most common pushback you get on this?
People often push back by citing exceptions or edge cases. And they're usually right that exceptions exist. But building a strategy around exceptions rather than patterns is a losing game for most founders.
