Cartesia Voice AI Platform

What do you like best about the product?

The availability of voices, most of them really natural and expressive, an agent platform with free credits and SIP out of the box

What do you dislike about the product?

Some voices aren’t good and miss the pronunciations (for example Dutch language), the team is really unresponsive at times, the agent platform itself extremely limited and requires external providers for better experience

What problems is the product solving and how is that benefiting you?

Text to speech voice AI in different use cases, collections, customer support etc

What do you like best about the product?

The standout feature of Cartesia is its ultra low latency text to speech generation.

What do you dislike about the product?

Its pre made voice library is smaller than older platforms. Additionally, as a newer specialized service, it lacks the extensive third-party ecosystem of legacy text-to-speech providers.

What problems is the product solving and how is that benefiting you?

Cartesia solves the high latency, robotic sound, and high computing costs of traditional voice AI by using State Space Models instead of standard transformers. This benefits me by delivering ultra-fast, natural-sounding, and expressive real-time voice interactions.

What do you like best about the product?

Its low latency to respond , multi language coverage

What do you dislike about the product?

It requires long form expressiveness , it is somewhat expensive

What problems is the product solving and how is that benefiting you?

It solves problem by translating text to speech with low latency by which it helps to communicate with others

What do you like best about the product?

I’ve been able to speak with real people to discuss their plans and features. Their support has also been very good: when I’ve reported bugs or issues, they’ve been fixed and addressed, and any questions I’ve had have been answered.

What do you dislike about the product?

Coding a voice agent comes with a bit of a learning curve. Claude Code really reduced that ramp-up time for me, though, and it makes me think that using any kind of AI coding agent could significantly speed up the development process for anyone considering Cartesia.

What problems is the product solving and how is that benefiting you?

They make it easy to have a voice agent automatically run an in-depth interview, and it still sounds pleasant and easy to work with throughout.

What do you like best about the product?

Cartesia helps me improve my pronunciation, since my first language is Spanish.

What do you dislike about the product?

Maybe the web page is a little boring, but the software is amazing.

What problems is the product solving and how is that benefiting you?

It helps me learn how to pronounce a lot of words that are hard for me. Since I use Cartesía, it’s easier for me.

What do you like best about the product?

The app is easy to use, and the policies are easy to understand.

What do you dislike about the product?

Nothing specific comes to mind from my initial use.

What problems is the product solving and how is that benefiting you?

It helped me handle day-to-day tasks more easily by creating agents.

What do you like best about the product?

Cartesia stands out for the natural quality and low latency of its AI voice technology. The speech generation feels responsive enough for conversational applications, where even small delays can make a voice interaction feel artificial. I also like the developer experience, with APIs and SDKs that make it relatively straightforward to connect voice capabilities to an existing application or AI agent. The platform's focus on real-time interaction makes it particularly useful for voice agents and other applications where responsiveness matters as much as audio quality. For teams building AI-powered voice experiences, the combination of speech quality, speed, and developer flexibility provides strong practical value.

What do you dislike about the product?

Cartesia is clearly designed with developers and AI teams in mind, so users without experience working with APIs, voice models, or AI infrastructure may need more time to become comfortable with the platform. I would also like more built-in tools for evaluating voice quality across different models and use cases, particularly when comparing latency, naturalness, and cost. Pricing can become an important consideration for applications with high volumes of real-time conversations, so clearer cost forecasting and optimization guidance would make it easier to estimate ROI before scaling a production voice application. More guided onboarding examples for common voice-agent scenarios would also improve the initial experience.

What problems is the product solving and how is that benefiting you?

Cartesia addresses the challenge of making AI voice interactions sound natural while remaining fast enough for real-time conversations. Traditional text-to-speech systems can introduce noticeable delays or produce voices that feel less conversational, which becomes especially problematic for AI agents that need to respond naturally and continuously. Cartesia's focus on low-latency speech generation helps reduce that friction and makes voice-based AI applications feel more responsive. The API and developer tooling also reduce the amount of custom infrastructure needed to add speech capabilities to an existing AI workflow, allowing teams to spend more time improving the actual agent experience rather than building the voice layer from scratch.

What do you like best about the product?

What I like best about Cartesia is the quality and naturalness of its AI voice generation. The voices sound remarkably realistic, with good clarity, expression, and responsiveness. It’s also easy to integrate into applications, making it a great choice for building fast, engaging voice experiences.

What do you dislike about the product?

One area that could be improved is the pricing and usage limits, particularly for higher-volume use cases. It would also be helpful to offer more customization and fine-tuning options to better meet specific voice and pronunciation requirements.

What problems is the product solving and how is that benefiting you?

Cartesia addresses the challenge of delivering natural, real-time AI voice experiences without the need for a lot of complex infrastructure. With fast response times and realistic-sounding voices, it becomes easier to build engaging voice-based applications, while also cutting down development time and improving the overall user experience.

What do you like best about the product?

What stands out about Cartesia is its fast, natural-sounding voice generation and low-latency performance. It works especially well for real-time conversational AI applications, and the developer-friendly APIs make it relatively straightforward to integrate voice capabilities into existing apps.

What do you dislike about the product?

Some of the more advanced voice customization options can take time to fine-tune for specific use cases, and the output quality can occasionally be inconsistent when dealing with complex or unusual inputs. I’d also like to see greater flexibility and more direct control over voice styles and pronunciation, especially when trying to match a particular tone or delivery.

What problems is the product solving and how is that benefiting you?

Cartesia helps us add fast, natural-sounding voice capabilities to our conversational AI applications without having to build speech infrastructure from scratch. The low-latency voice generation makes interactions feel more responsive while also reducing development effort, so we can build, iterate on, and deploy real-time voice experiences more quickly.

What do you like best about the product?

The best thing that i like about Cartesia is it's easy to use interface and Text to speech creation. You can easily generate text to speech with just adding the content you want to generate the audio for.

What do you dislike about the product?

The one thing that i dislike about Cartesia is at times the audio sounds a bit robotic and not natural or human.

What problems is the product solving and how is that benefiting you?

The problem that cartesia is solving for me is text to speech. I can easily create text to speech audio for my content.
