Cartesia Voice AI Platform

What do you like best about the product?

I like how natural and responsive the voice technology feels. The speech sounds smooth and expressive rather than overly robotic, which makes a big difference when using it for customer facing experiences.

What do you dislike about the product?

That there can be a bit of a learning curve when you start exploring the more advanced options. The basics are fairly straightforward, but getting everything configured exactly the way you want can take some experimenting.

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

Helping me create more natural voice based experiences without having to rely on traditional recordings or spend a lot of time producing audio manually. I can generate realistic speech quickly and make changes when needed, which is esp useful when testing different customer interactions or support scenarios.

What do you like best about the product?

I like how straightforward Cartesia makes it to set up and monitor AI voice agents. The Calls section gives me a simple view of completed calls, call type, duration, and other details, which makes it easier to keep track of how an agent is being used. The setup also feels approachable when testing an assistant for real business use cases.

What do you dislike about the product?

Some areas could provide more detailed information around individual calls. I would also like to see more flexibility and deeper reporting options as the number of agents and calls grows.

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

We use Cartesia to experiment with AI-powered assistants for business workflows and customer interactions. Being able to create an assistant and monitor its calls gives us a practical way to test conversational automation without building the entire voice infrastructure ourselves. It helps us evaluate where AI agents can reduce repetitive communication work and improve responsiveness.

What do you like best about the product?

What I like most about Cartesia is how easy it is to experiment with its AI voice features. I especially like the voice library because it offers a range of voices, accents, and languages to choose from, so it’s simple to find something that fits. I also appreciate the voice agent setup and the pronunciation controls. Being able to test these features on the Free plan makes it a solid option for trying out voice ideas before spending money, and it helps me plan my pricing budget accordingly. Also Ui/UX is so smooth to understand that i walkthrough each and every page and it was self explanatory.

What do you dislike about the product?

I dislike about cartesia is that I got little bit confused at frist because different features use credits differently. every feature has diffeernt credit usuage for some its by character , while other have on time , etc which is like i cant guarantee when tokens get consumed by how much.

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

The pronunciation problem is what Cartesia is solving for me. It enables me to create a custom dictionary, which is really useful when using AI voice that needs to correctly say product names, categories, and division/vendor names in our use case. For example, “Bud Light” sometimes gets pronounced like “bird light,” and this helps prevent that.

The Voice Agent section was another strong part of the platform. You can create an agent and connect things like instructions, tools, and a knowledge base, which was a lifesaver. That way, when customers ask questions, we can be more confident the AI won’t hallucinate.

What do you like best about the product?

The biggest advantage is the low latency, which makes conversations feel more natural and responsive. The voice quality is also quite natural, especially for conversational use cases. It integrates well with our existing voice-bot stack and has been relatively easy to implement.
The streaming capabilities are particularly useful because we can start playing the response without waiting for the entire audio to be generated. We use both STT/TTS voice models, and the voice model rates are best in market.

What do you dislike about the product?

Indian English and Hinglish pronunciation can sometimes be inconsistent, especially with names and local terminology, so it takes many trials to get it right. More granular controls for emotion, tone, pauses, and overall speaking style would also be helpful. The voice library could include more high-quality Indian voices and additional regional language options, although this may be a plan limitation on our side.

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

We use Cartesia TTS/STT as the voice-generation layer for our AI voice bots. The key requirement is to generate natural speech with very low latency so customers can have a smooth, real-time conversation.
Cartesia helps us reduce the robotic feel of automated calls while maintaining the responsiveness required for customer-facing conversations. This is particularly important for use cases where even a small delay can make the interaction feel unnatural.

What do you like best about the product?

the ease of use, and the incredible real human voice output

What do you dislike about the product?

the cost of the solution is very high if used at a professional level even for the pro model

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

have the ability to create an agent that contacts people to invite them to an event

What do you like best about the product?

As a PM overseeing our automated support workflows, latency is the biggest bottleneck we face with voice AI. Cartesia's Sonic model essentially eliminated the awkward pauses in our voice bots. The sub-200ms generation time is noticeably faster than other major providers we tested for our stack.

What do you dislike about the product?

The core API is solid, but the developer dashboard and usage analytics are still pretty barebones. When I'm trying to pull quick reports on token usage or track down specific error spikes during peak operation hours, I usually have to rely on our internal logging rather than getting a quick visual from their UI. Also, fine-tuning custom voices requires a bit more trial and error than expected to get the pronunciation of industry-specific terms exactly right.

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

We are building out real-time conversational agents to handle initial tier-1 customer support queries. Cartesia solves the "uncanny valley" problem of slow, monotone AI voices. The primary business benefit has been a noticeable drop in caller hang-ups during the initial bot routing phase, purely because the voice sounds natural enough and responds fast enough that users don't get immediately frustrated.

What do you like best about the product?

Very realistic voice over and sound quality + speed generation

What do you dislike about the product?

I don’t like how the accents are limited

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

Ai sales calls

What do you like best about the product?

I use Cartesia to translate papers from Spanish into English. In comparison to the other tools such as Claude and other AI tools, I believe that Cartesia is the quickest in terms of rapid translation. I would recommend this app among a few others for those who are bilingual or learning multiple languages.

What do you dislike about the product?

I don't have anything negative to say. Maybe an expansion of languages you can translate from/ a few more voices?

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

Right now I use Cartesia for articles that are not translated online. I read a lot in English and Spanish and this helps me learn more throughout the day. Overall, the software runs great and is quick. Also, you can utilize their free features before paying more for additional features.

What do you like best about the product?

Cartesia actually has one of the best Gen AI TTS services out there. The voice actually feels too natural and not robotic at all. The latency is also negligible. UI/UX to try and test the voices is much friendly for even a beginner. The accessibility of Cartesia to be integrated with tools like LiveKit, etc. makes it all the worth of its cost. Moreover, their support and customer success team makes it too easy to onboard.

What do you dislike about the product?

No such things to dislike but if you are a bit shorthanded on cost side of things, you can try other alternatives out there.

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

Cartesia is making our Voice AI agents feel natural and make it a lot User friendly, rather than most of the agents out there who are a lot robotic.

What do you like best about the product?

I really like how quickly the text-to-speech works

What do you dislike about the product?

Sometimes the voices don't sound human enough

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

I don't have time to read long things so it is nice to be able to listen to them instead
